Just an fyi, but before touching load line calibration check for stability of the curve offset first. If you don’t need to touch the load line, don’t. It still increases voltage under load compared to auto which leads to higher temps. This is just to make certain offsets stable when needed.
Came from Intel 6700k. I got that to 5ghz with 1.45 volts. Amd 7900x3d now and it’s so different. Helpful guide! I’m close to world record on 3d mark for a 3080 and 7900x3d set up (says “record for this exact combo of 3080 and 7900x3d” so I’m chasing that haha.
5ghz on a 6700k vs a modern cpu isn’t even comparable lol. Also the 7900x3d is a weird cpu where you have the voltage limitations of the 3d cpus and reduced benefit of 3d vcache since it’s only on half the cpu
@@josephbargo5024 obviously not comparable, but considered that majority of people could not hit 5ghz was pretty crazy. The boost stuff with amd is weird but I found not worth it really to mess with. I didn’t get much gains from anything or any guide I’ve tried, and I’ve tried a lot.
This makes sense, but then Bullzoid suggests that LLC is generally a bad thing, because of the spikes it causes. Confusing... Couldn't you just reduce the CO offset and get the same VCORE result as raising the LLC, but with less transient spikes?
Thank you for that. Without the extra step that you showed I could only cap out at -33. I could do higher for Cinebench but it failed on stability tests. Once I adjusted the LLC I was able to get it to pass OCCT running for an hour at -40 and capped out at 75C. it should be noted that the LLC does increase temps the higher you go but I was still able to keep everything at a reasonable temp with a 280mm AIO.
After you pass a prime95 run of about 6-8h you can say the settings are good. I can run cinebench with even -45 on my 7800x3d but man...the second I press start in prime...boom, crash. After that I started to test each core in OCCT and found out that, 7 of the 8 cores can run at between -21 and -25 and one core is absolute "garbage" and can only run at -13. Yes, curve optimizer is the way to go to lower the temperatures but the architecture on the am5 platform, especially on the 7800x3d is a bit weird, you cannot boost that high the clocks and needs at least a few days of testing to say that your system is 100% stable. After doing all these tweaks I then tested in prime95 and OCCT for about 12h each (the average time my pc is open) and had 0 errors. I saw someone said that picking individual offsets for each core can lower your performance...that is 100% false. You gain performance by doing so, cause each core can boost higher depending on the offset. If you can make 7 cores to boost at a bit over 5ghz and one stays below 5, will always bee better than having all cores limited to 4.8.
The 7000 series x3D chips are technically locked. The 7800x3D will not boost past its top speed of 5050hz without some infinity fabric or multiplier tweaking as the boost overide settings do nothing. It's online but I'm not sure if it is prime stable.
The guy who said you lose performance by applying per core offsets was Michael, one of the first comments. He is greatly mistaken and is applying trying to set per core FREQUENCY in CCD/CCX (not per core CO), which in that case can't be done as it defaults to the lowest core's speed. However, (as you and others have mentioned) per core CO is completely different as it adjusts the voltage offset (not frequency) and it works great . Just a thought on stability testing: Some of the stability tests you mentioned are unrealistic compared to what most people will actually stress their systems in real-world cases. I tend to stress for my worst-case real usage. You could be losing a lot of performance if you stress test for something way outside of your worst-case real-world usage scenario... just something to consider.
@@jimmyhuang7481 You are correct, some of the higher-end mobos, such as the Asus x670e Hero, have a separate bClK adjustment. You set eCLK to asynchronous mode, bCLK1 stays at 100, and bCLK2 you would adjust for cpu frequency (to like 106 or 108.15, etc). Employing that function/strategy/technique along with others can achieve some great overclocks on a processor that is otherwise "locked". I've had a lot of fun with the 7800x3d :)
@@RKBenchmarker i always stress test for worst case scenario, but as you said that is unrealistic for most cases, as I usually game on my pc, for example forza5 or cod can run with no problems, cyberpunk crashes my system the second I play start. Sometimes even the basic youtube videos crashed my pc. Since then i try to find the perfect balance between 100% stability and usual workload/gaming stability. But you cannot go wrong with 100% stability, even at a loss of 2-3 fps.
@@Focaz With your knowledge, you and others could easily set different bios profiles for a set of different games/scenarios if you wanted to take the time. Just another option in the long line of options :) Game hard my friend!
Wait..... But if you're reducing the voltage per clock under a specific load..... Then raising the LLC..... That means that the voltage is higher at a specific load so you're undoing the benefits you just got from Curve optimiser. This does not make sense to me
CO undervolts the old 5Ghz. But now at same voltage you get 5.2Ghz. This is not stable at the same voltage so you need overvoltage, since the CPU is locked, LLC is overvoltage workaround.
Mine can only do -20 negative offset. Your one must be a super golden sample. But, I made sure mine is stable on every stress test and game test possible
@@AverageAsianJoe Those are the weakest cores, so offsetting those isn't going to reduce temps all that much. In fact, the gaming cores have less room for offset than the other cores. The main reason why the 7950X3D is lower power than a 7950X is because of those gaming cores being lower clocked and temperature limited by the 3DVCACHE, which heats things up. So the main problem is the weaker cores run hot, and can't be undervolted as much, while the stronger cores run cooler at the same clocks but also reach higher clocks. The problem with LLC though is while it stops Vdroop, the opposite side of that coin is you get voltage spikes when load drops, which is actually worse for your CPU in the long run, because you're getting a lot of voltage pumped through a core that is essentially idle, which is far worse, because you're not doing anything with that energy, it's just scouring through the circuits with nowhere to go but to dissipate into heat, which means you might not get higher overall temps, but you will get very high temps over a smaller area of the chip that the sensors won't pick up. So it's like if a small part of your cores suddenly went up to 100c, but in such a small area that as it dissipates through the chip, by the time it reaches the sensor it's only reading at 70c or less. This means very sharp spikes in voltage/energy, which is worse for electronics than a gradual shift. Temps aren't what kills hardware, it's voltage over time, and voltage spikes. The sudden shifts in voltage results in more dramatic energetic activities in the materials of the chip. This is one reason why the IHS is soo thick in the first place, it's to keep different areas of the chip from becoming too different in temperature, otherwise those temperature differences at such small scales results in more stress on the materials, including physical cracking and delamination from each other. That's the main reason why the VCACHE is limited in temp. Not because it can't run at those temps, but because it would crack/delaminate from the CPU, because it's not so much built into the CPU, but rather, pasted on top of it and connected by thin circuits. If it was actually manufactured with the chip itself, rather than manufactured separately, the temp limits wouldn't even exist.
just for information. running llc on extreme will generate extreme voltage spikes for a short time when the load drops off. this can lead to huge voltage numbers for a short period of time. i dont recommend running llc on extreme!
Thank you for this. Informative without going too far down the rabbit hole and losing the point. I see lots of undervolt videos and nothing about the load line. It helped me get more boost and cooler cooler temps. Can't beat that.
I didn't win the Silicon Lottery and left it on auto and got better performance. So placed my NVME Drive to the middle of the MB and got PCIE4 instead of PCIE3 and got better performance but ran hott. My graphics card slowed down so I placed it back and the NVME is just a little slower but the GPU is at full speed. Cheers!
Yes, most CPUs won't be able to do -40 however, LLC prevents the significant vdroop under full load that would be incurred from such as high negative offset. At the same time, the negative CO offset prevents the higher voltage spike that would normally occur after transitioning from full load to low load or idle; due to using LLC.
I have 7950x3D and I am with MB X670E-PLUS with the "Negative 20" curve Optimizer my PC restarted 2 times in a matter of 3hrs ish maybe? I also Set the Thermal Throttling to be at 75* Cel. Would that mean that my CPU doesn't tolerate even -20 o the curve settings?
It is working on msi as well, just find the right option. And -40 might work like here with 5600mhz 30-36-36, but if your ram is 6400cl32 then u need to give more V, because at the same cpu speed let say 5ghz the ccd will have more data to work with from memory controler therefore it will need more V to work properly.
Don’t think that an AIO is gonna give you -10 C. That ain’t happening. I cool an i9-12900k with a Noctua NH-D15S and it barely hits 82 C at 100% CPU load.
I have the Terra case (mini ITX) I was struggling with finding a fan that could cool my 7800x3d. I have set my offset to negative 35 to reduce temps which is great . Will changing the LCC off auto increase cpu temps the higher I increase it?
Negative 15 BSOD's me. However, my 7800x3d did win on the FLCK lottery and im able to run a 6400mhz memmory kit with 2133mhz on the infinity fabric. So the lottery is not speficly bound to the curve optimiser.
whoop whoop whoop 😏 thanks bro I follow your guide for my 7900X , I still stable at negative 45 with extreme level calibration , also I just add in my setting temps to reach until 85 in my Aorus Master X670E , got on cinebench23 a score of 29700 , and my volts do not pass the 1.20 level , I monitoring my voltage in multitask heavy application or sleep mode doing nothing and again my volts dont even reach to 1.20v
I follow all his settings for my 7950x3d and it crashed when running CPU benchmark , BLUE SCREEN so if you don't wanna kill your CPU don't follow this video or don't do EXTREME profile, don't put -negative 40 try other value -30, -20
Asus LLC is opposite of others; Asus, highest number is most voltage applied to vdroop. (On other boards, the lowest number is most voltage applied to vdroop).
You probably don't have to worry about it because you're undervolting, but the issue with setting a stiffer LLC is it can cause voltage spikes on transient loads. Youre fully loaded, the LLC is compensating, there's a cache or memory stall which unloads your CPU but because you're running extra vdroop compensation your voltage spikes until the power stages catch up or the CPU loads again. Finding the stiffest value that doesn't cause this requires hooking up an oscilloscope to the voltage probe points on your motherboard, as it varies by model/manufacturer/bios revision.
I've been building pcs for fun for over 20 years. I retired early ,age39 (hey Fu I'm still young at heart) lol but 1) I always buy nvidia gpus And 2) up until last year always purchased Intel cpus. Last year I built 3 pcs for myself. Total overkill, one was for my virtualpinball build I built,the other was for my 32inch rec room masters arcade cabinet build. Both pcs are identical, msi mpg x570 gaming edge wifi motherboards, Ryzen9 5900x cpus, Nzxt 360mm aio coolers , both in corsair 5000D airflow cases. The only difference was (remember this was during the gpu drought) my virtual pinball machine has a rtx3090 founders edition, and my arcade has a rtx3080ti. I fell in love with amd cpus specifically that ryzen 9 5900x 24threads @4.7ghz was no problem. Ok sorry for the backstop but if everyone here is into pcs and tuning them etc, I love seeing peoples builds and hearing them talk about their systems just as car enthusiasts have car shows. Anyway, I went with the gigabyte Aorus X670E Master motherboard (thank God so nothing exploded) ryzen 9 7950X3D, grabbed the only pcie5 m.2 drive I could find (microcenter Inland 2tb pcie5 m.2 drive for only $179!!, and yes it gets read and write speeds over 10,000gb/s) It took lots of updating drivers and bios's but finally the cpu is running as intended. I think I just set my negative to -20 and left it. Right now I'm using the motherboard above, so hoping some of you are familiar with the layout. 1) I'm unsure but are you saying the graph you show , if its still on a negative curve , even on extreme, it's safe to leave it like that? 2) under where we turn pbo on to advanced, then motherboard, there's a scalar option that's on auto but goes 1-10. Should we just leave that alone? Lastly, I want to apologize for all the questions, if you got to know me you would know I try and help every person I can for arcade builds, pcs etc. But I'm a grown man and can admit, all my years of experience isn't really helping with this ryzen9 7950x3d. It idles around 40°C and usually games or benchmarks around 60-65°c. Does that seem like normal temperatures? My cpu cooler is once again the NZXT 360MM kraken. I appreciate anyone whose read this, I have a disability after almost being killed at work so I'm still trying to fight my way back mentally. As I always do, I like and subscribe to any fellow tech youtuber, even though I'm new at it and onky have 1500members lol 😅
Thank you guys for taking the time to read my long ramblings lol I've loved building pcs since my first 386sx 25mhz pc build. I think it had windows 3.1? Or windows for workgroups whatever was before windows 95.

Lol scored a intel 486DX 66MHZ CPU, WITH 4MB OF RAM. LOL God anyone remember having to run memmaker? Because of the way we had to run games in DOS? Lol
Coupled with the other replies, you must remember that the x3d is different than the x, which you normally wouldn't set to the highest setting. The x3d voltage won't go above its limit. LLC only helps the vdroop remain more stable.
any idea why no matter what curves i set i get no instability also 7800xd im only scoring 15-16k cb23 temps maxing around 81 it seems like no matter what setting i do nothing changes. i feel like i should be benching 19k ddr56000, 360 aio volts also always look the same under all settings i try
Not sure what I’m doing wrong. Using a 7800 x3d and a rog strix b650a. Set the negative on minus 35 on all cores. And the LLC on level 3 of possible 4.

Yes, the 4080 is 320w normal usage 280-300w thats a lot of heat. Install the exhausting fans. Also dont use negative curve -40 all cores like here. With 6000mhz ram and loose timings like 40 40 40 it might work. But if u will go 6400 cl28 or 7800-8000 cl36 100% wont work. Especially in the games. The programs might work but there will be a micro stuttering. With 6400 -30 with 8000 -25 or -20. If u dont believe try to set default 4800 cl 40,40 40 and -50 negative all cores 100% will work. The high temps are always bcos of heat accumulation. So i would say exhaust fans are the best. 🎉😊

I just switched to these AMD CPUs and clearly I need to read up and learn. Because this video to me seems like there's a single attribute (core voltage) that is controlled by two settings, curve and LLC. And that we can lower core voltage more if at the same time we raise it using LLC. I must have misunderstood something.

CPU soc voltage is very important, not just something people are talking about these days lolllllll and for x3d parts, i would seriously consider looking into the purpose of vdroop. Cool overview though. Also worth disabling integrated graphics, actually makes a diff believe it or not
MSI does not have the graphical slopes for load line calibration and the only options are auto and modes 1 to 8. No useful guide in the bios. The explanation in this video is still too technical to translate in simple terms.

What wasnt mentioned is that you can also get a mobo that has an external clock generator and overclock the cpu bus. Something to consider additionally is that extreme LLC will put strain on the VRM. Depending on your board and your cooling scenario this can affect the life of your motherboard. Air cooling is actually better for cooling the VRM.

Thank you for that. Without the extra step that you showed I could only cap out at -33. I could do higher for Cinebench but it failed on stability tests. Once I adjusted the LLC I was able to get it to pass OCCT running for an hour at -40 and capped out at 75C. it should be noted that the LLC does increase temps the higher you go but I was still able to keep everything at a reasonable temp with a 280mm AIO.
After you pass a prime95 run of about 6-8h you can say the settings are good. I can run cinebench with even -45 on my 7800x3d but man...the second I press start in prime...boom, crash. After that I started to test each core in OCCT and found out that, 7 of the 8 cores can run at between -21 and -25 and one core is absolute "garbage" and can only run at -13. Yes, curve optimizer is the way to go to lower the temperatures but the architecture on the am5 platform, especially on the 7800x3d is a bit weird, you cannot boost that high the clocks and needs at least a few days of testing to say that your system is 100% stable. After doing all these tweaks I then tested in prime95 and OCCT for about 12h each (the average time my pc is open) and had 0 errors. I saw someone said that picking individual offsets for each core can lower your performance...that is 100% false. You gain performance by doing so, cause each core can boost higher depending on the offset. If you can make 7 cores to boost at a bit over 5ghz and one stays below 5, will always bee better than having all cores limited to 4.8.
The 7000 series x3D chips are technically locked. The 7800x3D will not boost past its top speed of 5050hz without some infinity fabric or multiplier tweaking as the boost overide settings do nothing. It's online but I'm not sure if it is prime stable.
The guy who said you lose performance by applying per core offsets was Michael, one of the first comments. He is greatly mistaken and is applying trying to set per core FREQUENCY in CCD/CCX (not per core CO), which in that case can't be done as it defaults to the lowest core's speed. However, (as you and others have mentioned) per core CO is completely different as it adjusts the voltage offset (not frequency) and it works great . Just a thought on stability testing: Some of the stability tests you mentioned are unrealistic compared to what most people will actually stress their systems in real-world cases. I tend to stress for my worst-case real usage. You could be losing a lot of performance if you stress test for something way outside of your worst-case real-world usage scenario... just something to consider.
@@jimmyhuang7481 You are correct, some of the higher-end mobos, such as the Asus x670e Hero, have a separate bClK adjustment. You set eCLK to asynchronous mode, bCLK1 stays at 100, and bCLK2 you would adjust for cpu frequency (to like 106 or 108.15, etc). Employing that function/strategy/technique along with others can achieve some great overclocks on a processor that is otherwise "locked". I've had a lot of fun with the 7800x3d :)
@@RKBenchmarker i always stress test for worst case scenario, but as you said that is unrealistic for most cases, as I usually game on my pc, for example forza5 or cod can run with no problems, cyberpunk crashes my system the second I play start. Sometimes even the basic youtube videos crashed my pc. Since then i try to find the perfect balance between 100% stability and usual workload/gaming stability. But you cannot go wrong with 100% stability, even at a loss of 2-3 fps.
@@Focaz With your knowledge, you and others could easily set different bios profiles for a set of different games/scenarios if you wanted to take the time. Just another option in the long line of options :) Game hard my friend!
I just set mine to medium to make a -25 all core more stable. No whea errors. This gave me a 14.5k in timespy
Wait..... But if you're reducing the voltage per clock under a specific load..... Then raising the LLC..... That means that the voltage is higher at a specific load so you're undoing the benefits you just got from Curve optimiser.
This does not make sense to me
CO undervolts the old 5Ghz. But now at same voltage you get 5.2Ghz.
This is not stable at the same voltage so you need overvoltage, since the CPU is locked, LLC is overvoltage workaround.
Mine can only do -20 negative offset. Your one must be a super golden sample. But, I made sure mine is stable on every stress test and game test possible
Try only offsetting your gaming cores, 1-8.
@@AverageAsianJoe Those are the weakest cores, so offsetting those isn't going to reduce temps all that much. In fact, the gaming cores have less room for offset than the other cores. The main reason why the 7950X3D is lower power than a 7950X is because of those gaming cores being lower clocked and temperature limited by the 3DVCACHE, which heats things up. So the main problem is the weaker cores run hot, and can't be undervolted as much, while the stronger cores run cooler at the same clocks but also reach higher clocks.
The problem with LLC though is while it stops Vdroop, the opposite side of that coin is you get voltage spikes when load drops, which is actually worse for your CPU in the long run, because you're getting a lot of voltage pumped through a core that is essentially idle, which is far worse, because you're not doing anything with that energy, it's just scouring through the circuits with nowhere to go but to dissipate into heat, which means you might not get higher overall temps, but you will get very high temps over a smaller area of the chip that the sensors won't pick up.
So it's like if a small part of your cores suddenly went up to 100c, but in such a small area that as it dissipates through the chip, by the time it reaches the sensor it's only reading at 70c or less. This means very sharp spikes in voltage/energy, which is worse for electronics than a gradual shift. Temps aren't what kills hardware, it's voltage over time, and voltage spikes. The sudden shifts in voltage results in more dramatic energetic activities in the materials of the chip.
This is one reason why the IHS is soo thick in the first place, it's to keep different areas of the chip from becoming too different in temperature, otherwise those temperature differences at such small scales results in more stress on the materials, including physical cracking and delamination from each other. That's the main reason why the VCACHE is limited in temp. Not because it can't run at those temps, but because it would crack/delaminate from the CPU, because it's not so much built into the CPU, but rather, pasted on top of it and connected by thin circuits. If it was actually manufactured with the chip itself, rather than manufactured separately, the temp limits wouldn't even exist.
Mine only is stable with -12
Mine is stable with Vcore 1,15v and -40 offset.

To be honest -30 is way above average undervolt if not in %5 of all chips. Yours is excelent -40 all cores wooow, must be hand picked unit :D
just for information. running llc on extreme will generate extreme voltage spikes for a short time when the load drops off. this can lead to huge voltage numbers for a short period of time. i dont recommend running llc on extreme!
This is not the same as applying a max llc to a non-x3d which you normally wouldn't do.
Agreed!
Thank you for this. Informative without going too far down the rabbit hole and losing the point. I see lots of undervolt videos and nothing about the load line. It helped me get more boost and cooler cooler temps. Can't beat that.
I didn't win the Silicon Lottery and left it on auto and got better performance. So placed my NVME Drive to the middle of the MB and got PCIE4 instead of PCIE3 and got better performance but ran hott. My graphics card slowed down so I placed it back and the NVME is just a little slower but the GPU is at full speed. Cheers!
Doubt that the negative value will be stable with prime95 or aida64 SHA3 testing
But nice to know that LLC improves stability
Yes, most CPUs won't be able to do -40 however, LLC prevents the significant vdroop under full load that would be incurred from such as high negative offset. At the same time, the negative CO offset prevents the higher voltage spike that would normally occur after transitioning from full load to low load or idle; due to using LLC.

You actually compensate with Extreme LLC the low value of Curve Optimizer.... which is wrong, but hey, have fun doing it.
This video didn’t help a single bit, why are there no videos with MSI motherboards???
It is working on msi as well, just find the right option. And -40 might work like here with 5600mhz 30-36-36, but if your ram is 6400cl32 then u need to give more V, because at the same cpu speed let say 5ghz the ccd will have more data to work with from memory controler therefore it will need more V to work properly.
What do you recommend having the PBO limit setting on, auto? I see someone recommending "disabled" and "motherboard".
does this apply for the new 7600x3d? its a 7800x3d with 2 cores turned off.
Don’t think that an AIO is gonna give you -10 C. That ain’t happening. I cool an i9-12900k with a Noctua NH-D15S and it barely hits 82 C at 100% CPU load.
I have the Terra case (mini ITX) I was struggling with finding a fan that could cool my 7800x3d.
I have set my offset to negative 35 to reduce temps which is great .
Will changing the LCC off auto increase cpu temps the higher I increase it?
Thank you so much, so far its working on -38 with Turbo LLC, just want to be safe ^_^...
Negative 15 BSOD's me.
However, my 7800x3d did win on the FLCK lottery and im able to run a 6400mhz memmory kit with 2133mhz on the infinity fabric.

HI, extreme LLC on Gigagybte, what does that translate to on asus boards? I have an x670e e gaming wifi?
Asus LLC is opposite of others; Asus, highest number is most voltage applied to vdroop. (On other boards, the lowest number is most voltage applied to vdroop).
You probably don't have to worry about it because you're undervolting, but the issue with setting a stiffer LLC is it can cause voltage spikes on transient loads.
Youre fully loaded, the LLC is compensating, there's a cache or memory stall which unloads your CPU but because you're running extra vdroop compensation your voltage spikes until the power stages catch up or the CPU loads again.
Finding the stiffest value that doesn't cause this requires hooking up an oscilloscope to the voltage probe points on your motherboard, as it varies by model/manufacturer/bios revision.
This is my concern (and what has prevented me from messing with the LLC); potential for damaging the CPU with overshoot.
Llc doesn’t raise or have higher spikes. It just helps hold continuous. Cheers.
I've been building pcs for fun for over 20 years. I retired early ,age39 (hey Fu I'm still young at heart) lol but 1) I always buy nvidia gpus
And 2) up until last year always purchased Intel cpus.
Last year I built 3 pcs for myself. Total overkill, one was for my virtualpinball build I built,the other was for my 32inch rec room masters arcade cabinet build.
Both pcs are identical, msi mpg x570 gaming edge wifi motherboards, Ryzen9 5900x cpus, Nzxt 360mm aio coolers , both in corsair 5000D airflow cases. The only difference was (remember this was during the gpu drought) my virtual pinball machine has a rtx3090 founders edition, and my arcade has a rtx3080ti. I fell in love with amd cpus specifically that ryzen 9 5900x 24threads @4.7ghz was no problem.
Ok sorry for the backstop but if everyone here is into pcs and tuning them etc, I love seeing peoples builds and hearing them talk about their systems just as car enthusiasts have car shows.
Anyway, I went with the gigabyte Aorus X670E Master motherboard (thank God so nothing exploded) ryzen 9 7950X3D, grabbed the only pcie5 m.2 drive I could find (microcenter Inland 2tb pcie5 m.2 drive for only $179!!, and yes it gets read and write speeds over 10,000gb/s)
It took lots of updating drivers and bios's but finally the cpu is running as intended. I think I just set my negative to -20 and left it.
Right now I'm using the motherboard above, so hoping some of you are familiar with the layout.
1) I'm unsure but are you saying the graph you show , if its still on a negative curve , even on extreme, it's safe to leave it like that?
2) under where we turn pbo on to advanced, then motherboard, there's a scalar option that's on auto but goes 1-10. Should we just leave that alone?
Lastly,
I want to apologize for all the questions, if you got to know me you would know I try and help every person I can for arcade builds, pcs etc.
But I'm a grown man and can admit, all my years of experience isn't really helping with this ryzen9 7950x3d.
It idles around 40°C and usually games or benchmarks around 60-65°c. Does that seem like normal temperatures? My cpu cooler is once again the NZXT 360MM kraken.
I appreciate anyone whose read this, I have a disability after almost being killed at work so I'm still trying to fight my way back mentally.
As I always do, I like and subscribe to any fellow tech youtuber, even though I'm new at it and onky have 1500members lol 😅
Thank you guys for taking the time to read my long ramblings lol I've loved building pcs since my first 386sx 25mhz pc build. I think it had windows 3.1? Or windows for workgroups whatever was before windows 95. Lol it basically could only run the paint app. Then I went to a computer show , some of you who are in your 40's like me remember having to go to computer shows to buy our hardware before the internet. Lol scored a intel 486DX 66MHZ CPU, WITH 4MB OF RAM. LOL God anyone remember having to run memmaker? Because of the way we had to run games in DOS? Lol
Coupled with the other replies, you must remember that the x3d is different than the x, which you normally wouldn't set to the highest setting. The x3d voltage won't go above its limit. LLC only helps the vdroop remain more stable.
My pc wont even boot with these settings any help?
any idea why no matter what curves i set i get no instability also 7800xd im only scoring 15-16k cb23 temps maxing around 81 it seems like no matter what setting i do nothing changes. i feel like i should be benching 19k ddr56000, 360 aio volts also always look the same under all settings i try
Not sure what I’m doing wrong. Using a 7800 x3d and a rog strix b650a.
Set the negative on minus 35 on all cores. And the LLC on level 3 of possible 4. My voltage goes up a little from 0.993V to 1.065V during cinebench. Tried some other LLC levels but only the cpu temperature decreases a little bit. Voltage goes up. Did I miss something?
Got the same motherbroad. Under "Precision Boost Overdrive", what did you select? There is no "Advanced" in the available options.

The programs might work but there will be a micro stuttering. With 6400 -30 with 8000 -25 or -20. If u dont believe try to set default 4800 cl 40,40 40 and -50 negative all cores 100% will work.

What wasnt mentioned is that you can also get a mobo that has an external clock generator and overclock the cpu bus. Something to consider additionally is that extreme LLC will put strain on the VRM. Depending on your board and your cooling scenario this can affect the life of your motherboard. Air cooling is actually better for cooling the VRM.
Overclocking the FSB is just an all around bad idea because now you are talking about OC’ing multiple components within the system………thereby increasing points of failure.

@@arlowicks9359 Yes……you are correct, the fsb can be overclocked by itself without affecting other components……yet……… it is still a bad idea and probably not worth the effort for the minor gains and eventual instability. What’s stable today probably won’t be stable in a few days.

@@GameTechReviews yea I already did that but no matter how low I set my negative it just won’t work did I get screwed lol
@@cizrx1599 Are you able to run it at stock without any changes in the bios?
@@GameTechReviews make a video how to make our 7950x3d perform the same as 7800x3d for gaming
I mean how does a $360 cpu beat the mighty 7950x3d 650$ usd CPU in gaming
Make a video for us 7950x3d users , i want the same performance as 7800x3d is giving
I dont like, that the Temps are going above 90°C. This makes the CPU throttling.
So I have a x670e-a and I’ve set the llc to maximum and I see no difference in performance. If I set it to standard or normal I get the same scores in cinebench. This normal?
It doesn't help performance scores, it helps stability so your computer doesn't crash.
@@Tarrgetthis gotcha ! Good to know! Thanks
@@Mexi99 Are you using Curve Optimizer? That's where you will see increases. LLC will help with vdroop so the voltage won't go too low and crash.
Is it still work? I do -50 mode1 x10
It still 78-81 when play game. Is it work? Or should i buy aio?
I need your advice. Two CPUs (7950x3d and 7800x3d) are available for sale: a new 7800x3d for €359 and a 2-month-old 7950x3d for €445. Which one should I go with? (Money is not an issue, and I have a 360 AIO cooler.) Which one should I choose for performance and future-proofing?
7950x3d is better.
In what situation would the llc need to be on extreme? It’s not necessary for regular gaming right ?
Amazing, I’ve been obsessed with overclocking lately. I guess I’m a true enthusiast lol 😂 but I’m learning more and more! Thanks to cool guys like you
I was like you back in the mid 20's. I manually enter all my DRAM timings now. Notice how I called it DRAM instead of RAM? I also correct people when they count DRAM speed in Hertz instead of transfers per second. Wanna buy that awesome ROG whatever mobo? Too bad it has throughhole DIMM sockets. Wanna know why that is bad? Trust me you don't. The fact that I can't bring myself to call a DIMM socket a RAM socket like all the normal human beings is reason enough for any of you to steer clear of any overclocking whatsoever. It all started when I first overclocked my Pentium 3 733 50 800 MHz back in the year 2000. The fact that I kind of know physics and material science makes all this unimaginably worse.
There is still hope for you. Cease all overclocking immediately. This includes using the curve optimizer because, well you really don't wanna know why.
@@ahmetrefikeryilmaz4432 plz explain why it's bad i do wanna know
@@-NoodleBoy I am going to save you from yourself and deny you the knowledge you seek so foolishly. LOL I am speaking like a Skyrim NPC
LLC is to battle vdroop by giving the cpu more voltage during workloads.
complete beginner here, if i used an air cooler and wanted to lower the average power usage during load and idle while achieveing close to the same performance, what can i do? ,
Hello guys,
I have a problem with this settings.
I have set a curve optimizer per core between negative 15 to negative 30 and loadline calibration to low, but when i run games, benchmark etc, my VID core have peak to 1.365Volt and when i simply wathc youtube o doing nothing the voltage VID stay from 1.2 to 1.3volt.
Have you any advice?
thanks :)
place the vcore lower to 1.2 volt
Hey man can we reach 6400mhz cl32 with gskill 2x32gb Rams? As i can see you are at 5600 at cl30. ❤
You can but just remember to change the ratio to UCLK = 1/2 MCLK
@GameTechReviews howcome you have to change the memory clock? I'm running cl30 6400 with uclk and memory clock at 3200 with no issues. Is this going to hinder performance? Seems good but I could be wrong? I do get higher scores than the average 7800x3d in cinebench
with new bios we i can reach 6400MHz C28 with 1:1 Ratio
@21CreativeMedia I've always been able to do 1:1. Got my CPU about 2 months ago .i believe it was 2 bios's before the current one. I can only manage cl30 with my ram though lol cl28 was unstable. But cl30 6400 1:1 has been perfect
What happens if my motherboard doesn’t have a graph for the LLC? My Asus board goes up to level 8
Mines not even 100% stable at negative 15. I got bad luck. I may try negative 10
How do I check the stability ?
@@GadgetsHigh undervolt like he's doing then save and reboot, run cinebench, if you get blue screen means your cpu is not a silicon lottery
return it and buy 7800x3d
Strange I can’t lower my power consumption not even little
Well done that man! 😄
My 7800X3D is only pulling 80W in Cinebench and not getting anywhere near the PPT limits, what’s the deal with that?
Same for me. Performs great tho, it's insanely power efficient
C R23 ~18k score 7800x3d + X670 Gaming X AX + 2x16GB G.Skill Flare X5 6000 CL32 EXPO = Bios settings PBO -40 , SOC 1.15v , VCORE OFFSET -0,050v ,LLC Auto , AIO ENDORFY F280 ~1600rmp on Cinebench R23 = 80*c , in game ~60-65*c 1100-1200rpm AIO

It doesn’t allow me to go to 40 it just says invalid, any help?
i found that changing some values in curve optimizer influences how other cores react,so i can go -33 on some cores and max -11 on others and if i set the -33 to something like -15 than the ones that couldn't run lower than -11 now can run -15...
is this a llc problem? it's on auto for me.
CO is undervolting for the old frequency but actually the voltage stays the same and now you get a higher Frequency at same voltage, as measured with a voltmeter...
