Great settings! I Díd in a 14900K and msi pro 790 A Max wifi with last bios Microcode 12B… results :max temp 77 , Max volt 1.370 in cinebench r23 and 39200 pts ❤
First of all a huge thank you for sharing your knowledge on this, the video and your comments have been very helpful! I'm about to build a computer with an i7-14700k and I'm absolutely scraping the internet for any bits of useful information on this issue beforehand. I'm looking to build tomorrow, do you think flashing to the latest BIOS on this board is the right move? Going off that the whole undervolting thing is very new to me. I've never touched anything in the BIOS before regarding overclocking and all that. I guess I'd like to know what your recommendation is going straight into a new build. From what I've gathered, I should flash to the latest BIOS and that should be it, but people are reporting their CPUs under performing, thus going back into the manual undervolting stuff... Edit: Sorry if you've answered a similar question already in your comments, I did go through them a few days ago but since then my brain has been wiped reading SO many conflicting experiences.
Hi! I agree to the suggestions that you should flash the latest BIOS which must contain the 0x12B microcode because the microcode will keep the VIDs requests under control and also because the latest MSI BIOS update introduces a new option to restrict the core voltage to a desired maximum value. All BIOS updates that came with intel default settings as an option, unfortunately, hurt CPU performance with more than one ways. This is by design, to correct stability issues that some people were reporting. Fortunately, you can get all, stability, low core voltages and the nominal performance by tweaking the BIOS settings to your particular hardware tolerances (what we call under volt). To summarise: YES you better make sure you flash the latest BIOS version and YES you better under volt your CPU to get the lost performance back. If you need further help please drop me a comment.
@@valentinosgsxr Thank you! I have my PC built, made sure to flash the BIOS before anything and I’m currently in the process of undervolting. I think I’ll follow through with your method here and see how that goes, however I did read that DC values shouldn’t be tweaked, what are your thoughts on that?
@@JimmyFund I know about some people are recommended not to change DC Loadline values but this doesn't appear to have a solid base. In my testing, DC value, when it is far apart from AC, it can cause clock stretching (drop of the clock speeds) and huge delta between VIDs and Vcore monitored values (which may be the reason of the clock stretching). On top of that, I found intel's recommendations for AC and DC to be the same. On top of that, I can argue that if it wasn't to be changed than who is to say which one is the correct value? Some BIOSs came with AC/DC 1300/1300 and some others 1100/1100 as default! There are instances that the BIOS itself is changing the DC values between different Loadline preset modes. So my recommendation is to go ahead and experiment with DC values as well. That's my two cents about this debate.
hi , i have same cpu and MB and the latest MSI BIOS update (Update CPU Microcode 0x12B) but i have not apply yet. have you change any value since the video upload date? ı wanna know before the apply these settings.
@valentinosgsxr what about the cooling type selection on the bios. I am using tower type, but in some videos choose box type cooling type instead of tower if you use tower type anyway. For much better results
@@moanizm New BIOS does not have tower cooling option. They just call it something else. Any profile will do as long as it does no restrict the power to lower than 253W. The 14700K can hit pick performance at around 230Watts if undervolted.
@@valentinosgsxr Hi again, :) I just finished the settings and test. Here are the results: 0140 didn't work, tested on Cinebench R24, and the test was crushed. reset the voltage to 0,130 and work fine. The 10-minute Cinebench multi-core test result has increased from 32k to 35k. It is amazing. The temperature was only max to 86 °C, which is fine too. same setup, and the cooler is a Thermalright peerless assassin 2x120cm tower cooler.
I have the latest BIOS version and set everything up just like in the video. The processor is i7 14700KF, the motherboard is MSI MAG Z790 Tomahawk, and the RAM is Kingston Fury 16GB 6000 DDR5. Initially, everything was fine for a couple of days. Synthetic tests like OCCT and Cinebench were normal too. But then, while playing a game, it completely froze a couple of times. I’m new to this topic, so what parameters can be changed, what should be increased or decreased? Thanks. P.S. The temperature was significantly lower.
@@blinkx584I don't know maybe because I have another motherboard I own msi pro z790-s wifi With these settings it didn't even let me start the test it says error check error files something like that
You need to decrease the offset. Instead of 0.150, try 0.130 and see how it goes. You may need to go even lower. It depends from your hardware's tolerances.
@@6a3g65 It should work similar to the pro. You need to drastically lower the offset from 0.150. Try 0.100 and if you are still not stable, go even lower 0.090, 0.080, 0.070 etc.
@@alessioactis1262 Not necessarily, offset is heavily depended by the "silicone lottery". If the your CPU is stable with whatever you are doing with your system, than keep it as is. If you notice instability (freezes, crashes or blue screens) back up a little and try again.
@@valentinosgsxr for now it seems stable, I also did cinebench and on games everything was normal, but so if strange things happen should I lower that value or decrease it?
@@alessioactis1262 Yes. If any program gives you instability issues, under volt is the first suspect (but not the only). In this case you reduce the offset and see if that fixes the issue. You better first reduce the offset by a lot, or even take it out of the way completely when you want to troubleshoot stability issues (until you know what was wrong at first place).
Would this work for a 14900f with a MSI b760-vc WiFi 7 motherboard with IA CEP enabled? Thanks for the video. I want to protect my chip while being able to undervolt for lower temperatures and faster speeds.
Hi. Those settings are not going to work on B760 or anything other than Z790 board because of the voltage regulation hardware difference. You can probably still undervolt tou CPU and will be beneficial, however I can not be more specific than that as I have no experience of this or similar motherboard.
Hi. In a system with the components listed below, can I perform a stable undervolt operation to prevent the processor from getting damaged at temperatures above 100°C? Is it all enough to do the things you did here? Components: Intel i7 14700K MSI MAG Z790 TOMAHAWK DDR5 Patriot Viper 2x32 GB DDR5 6000 MHz GALAX RTX 4070ti Super 16G MSI MAG CoreLiquid 360R v2 360 mm
HI. Yes, those settings are applied in the same platform as the system you are planning. If your system is unstable, reduce the offset to increments of 0.020 until your system is stable.
@@valentinosgsxr After performing undervolting on the 14700K processor, did you experience freezing, crashing, stuttering, or blue screen errors in games and under maximum load during benchmark tests? I've been very indecisive about building a system with the 14700K. Do you think I would be satisfied if I build a computer like that?" Please help.
@@tolgakes88 I am happy with my 14700K as it is fast and it proved reliable to me so far. Under volt can cause instability if the voltage provided to the CPU is not enough for the CPU to function properly. There is a limit to how low you can turn the voltage down while the processor is maintaining its pick performance. Under volt a CPU or a GPU requires a basic testing of the settings to the particular or future conditions of operation of any system. In addition you have to be ready to fine tune your settings whenever you have a new application that is crashing or freezing.
@@valentinosgsxr What is the max CPU temperature (Cinebench) after undervolting? Also, could you please use Prime 95 for testing your 14700K and tell me what the max temperature is?
I already uploaded a short video running Cinebench R23 with similar settings. There will be no difference running prime95 temperature whise. The max temps depending from many factors such as cooling solution, pc case, amount of under volt your CPU can handle, ambient temperature etc. So, don't look at the temperature as a solid number. Don't worry about the CPU getting damaged from high temps unless you remove the temp restrictions from your BIOS, but why would you do that! Your goal should be for the CPU not to thermal throttle under max load and normal conditions.
Hi. Yes, I still recommend similar settings for the 14600Kf but not the same. If you are on MSI Z790 motherboard (any flavor), then you can still try the LLC mode 4 with confidence. For the i5 I would start tweaking with even lower AC/DC Loadlines. Try 5/5 and see if your VIDs are close to Vcore and you are not losing clock speed. The offset should start from low value to high, so I would start from negative 0.100 and work my way up.
@@valentinosgsxrThank you for the quick awnser. I enabled LLC 4 and set the AC/DC Loadline to 5/5. Do I have to enable the offset mode? I have no idea what it does and my system seems to be running just fine.
@@Chris-hq7mb You still better off tweak the offset because this is the actual under volt setting. It will drop all the VIDs requests by the value you set to (As a result it will lower the power consumption for the same load and the package temperatures. Extreme under volt it can hurt performance and stability). If you don't want to test and figure out the maximum negative offset that your system can handle, then you can use a "safe" value that it would work for the majority of the systems. In my experience this would be 0.070 for the i5. If your system is not stable in a particular application, you can always go back and lower the offset to 0.060 or even lower, until you have no issues.
I am very confident that this strategy will work fine with your system. However you will have to figure out the values of the settings yourself. If your motherboard is an MSI, test LLC modes 3 and 4. AC/DC value of 10 should be good in any of those two modes. Finally, adjust the offset so that the board will produce around 1.320V Vcore during benchmarking. Reducing the voltage just enough for your CPU to be able to maintain 5.4Ghz on P cores and 4.3Ghz on E cores (effective clocks). I use one pass of Cinebench for testing and HWinfo for monitoring. It is very useful to keep logs (a spreadsheet) of the most important values so that you can validate the results of your different settings. Once you find the minimum acceptable offset you can start evaluating stability by testing with more dynamic loads (such as OCCT or Nvidia drivers installation or whatever is the most demanding application that your computer is running in regular base). Usually you are going to backdown the offset by 20 to 30mVolts bellow the optimum so that your CPU can be sufficiently stable . Let me know if you need more details.
Hi. First make sure that XMP is causing the crashes because rarely does. When you establish that XMP is the problem, you can manually tweak the speed, latency and voltage of your memory until is stable. You can find many guides of how to tune memory in youtube. Or you can just disable XMP because you are not going to see substantial difference in gaming performance anyway.
@valentinosgsxr Thank you for answer! A couple of days ago, I built myself a new computer with an i7 14700k, 4080 super, an msi z790-p wifi motherboard and xpg lancer blade ddr5 16 GB (x4) 6400 GHz RAM. But in a regular mode, it runs at 4000 Hz. I tried running on xmp and got black screens in cs2. After turning it off, everything started working fine. I assume that this is exactly the problem with xmp, maybe I really need to adjust the voltage parameters and other things for them?
This is a good question. The answer you can find yourself. Since you are confident with building a system, just try remove two of the sticks, enable XMP and see how it goes. You don't need 64Gigs of RAM to play cs2. Let me know how it went. And yes, it is possible that 4 sticks of two sets to be unstable especially if they are of different chipset manufacturer.
Will that effect the preformence for my cpu? Just did it and faced lof of issues like screen blinking and crash without reaching high temp Will not try this again Motherboard: msi z790-s pro wifi
Once you fix the instability, performance should improve. To fix the instability you need to reduce the negative offset. This is the 0.150 you punched. Lower this to 0.100 and see if this working. Lower more, until your system is stable.
This can happen if your AC/DC loadlines are too low for your selected Loadline Calibration curve. Also take it easy with the offset. Start from 0.070 and work your way up. Let me know.
Whatever cooler can handle 250Watts should be good enough. All 420 and 360 and 280 AIOs are OK. Some 240 may be good enough as well but most are not. I wouldn't cool any CPU that's capable of running at more than 160Watts with an air cooler.
Hello! I have the same motherbord and cpu. 12b microcode, I tweaked nothing but memory xmp to 6400 mhz and while gaming p-cores run at just 4200 mhz instead of 5500 mhz.(for a few seconds 5500 mhz but it goes back to 4200 mhz)) How many is your p-core clock while gaming? Thanks to your answer.
Haven's try it yet but I believe the same settings will work. If not, they will only need some small modification. I was thinking to flash the new BIOS after it comes out of the BETA state. If you re not willing to try yourself I may try it tomorrow.
@@valentinosgsxr i have the same motherboard and CPU, but 64Gb Ram and AIO LS720 360mm but have: Max CPU package power = 241 Watts, maybe due to of RAM size Max Core VIDs = less than 1.2 Volts Max CPU package Temp = 78 stable (80 max) So idk looks like last BIOS have some changes in Max Core VIDs by default and also why i have much more Temp than u ?:(
@@googlerdoodler458 All numbers are looking good. I wonder what is your multicore score at R23. The difference in Package Power is margin of error and it is explained by the VRMs tolerances and the overall tolerances of the motherboard. Also the higher temperature is slightly increasing the power consumption and this is normal. Less VID request, again is margin of error. 80C for full load is a great result. The package temperature varies according to the current ambient temperature. I am also using a 420mm AIO in a full tower case. Happy to hear that my video helped, that was the sole purpose.
Hi. Loadline calibration curves are related to the motherboard's hardware and it wont work the same. Offset tolerance mostly depends to the CPU so you can always try the offset method. No, you can't punch those settings straight to your motherboard and expect it to work the same but all the settings are there under different menus and names. You need to find a guide for the particular motherboard/CPU compilation if you don't want to experiment your self.
Hello! I did everything the same as you did in the video, but for me the p cores only run at the frequency of the e cores, so the p cores only run at 4200 mhz. I think the cpu is faulty because I did a stress test with a weak cooler and it was often at 100 degrees. Before the stress test, the p cores were working fine at 5500 mhz. What do you think?
Hi. It is possible that you damaged the CPU running it with insufficient cooling but the symptoms usually are crashes, restarts and blue screens. If you want to troubleshoot further, I suggest you run cinebench R23, monitor with HWinfo and take notes of maximum effective clocks, max CPU core temperature, max VIDs and max Vcore as well as your score and let me know. You should also lower the offset because 0150 is extreme for most CPUs and cinebench might crash.
@valentinosgsxr Next week a 360 mm cooler will come and I wiil try. But I ran cpu health program and everything was ok including cpu clock. If I'm playing and stop the game and open msi center hardware monitor it shows 5,5 GHz but when I continue playing clock goes back to 4,2 GHz.
@@ferencdavid1763 Well, depending on how this game is scheduling the CPU usage, the 4.2GHz could be normal behaviour. It also depends of which values you are looking at. Effective clock rate is usually lower than the targeted clock rate. I am suspecting that your CPU is just bored during gaming having not much to do, but this is easy to be proved by benchmarking.
@@valentinosgsxr The cpu usage 10-15% it drives 3070 ti in 1080p but before stress test the cpu ran 5,5 GHz under games. And under every game it runs only at 4,2 GHz. But I will inform you after test next weekend after installing the New cooler.
@@valentinosgsxr hi man. So i should tweak the setting like your after my bios update ? Running the same cpu like you but with z7790 tomahawk max wifi.
@@UfrxhEdi Hi. I haven's flash the 0x12B yet but according to intel it is just a summary of the previous microcode fixes. So yes, I believe nothing is changed in that regard. I would definitely recommend you to under-volt no matter the BIOS version. My settings are very likely to work for you as I also run a Z790 tomahawk in this system. Let me know how it goes... I will probably flash the new BIOS when it's out of its BETA state, just because I m sick and tired with the pushed BIOS' that change very little anyways.
@@UfrxhEdi I may didn't express myself correctly to my previous comment. What I was trying to say about the motherboards is that MAG and MAX they share the same VRMs so the under-volt settings should be comparable.
I got the asus ROG STRIX Z790-A GAMING WIFI motherboard and clueless on how to do this shit since i have the i7 14700k. Intel need to screw their heads on.
You don't have to under volt your CPU if your system is running OK. If you choose to do so, just do the offset tweak and leave the rest alone. The settings are there but in different menus and similar terminology (if not the same).
Hi. If you still haven't figure out your settings, I found a guide here on youtube with a very simple method to get voltages under control, only withdraw is that you are leaving around 10% performance on the table. Check it out: ruclips.net/video/DYDwh9ugTew/видео.html
Hi, I don't have a discord tag. What would you like me to upload? If you are on an MSI Z790 I definitely recommend you to follow this guide and test your system. Just don't go for 0.150V offset straight away because "silicon lottery" is a thing and the tolerances are slightly different from CPU to CPU.
In case anyone wonders, the same settings are working just fine with the new 0x12B microcode (or slightly better judging from my initial testing).
Great settings! I Díd in a 14900K and msi pro 790 A Max wifi with last bios Microcode 12B…

Once you find the minimum acceptable offset you can start evaluating stability by testing with more dynamic loads (such as OCCT or Nvidia drivers installation or whatever is the most demanding application that your computer is running in regular base). Usually you are going to backdown the offset by 20 to 30mVolts bellow the optimum so that your CPU can be sufficiently stable . Let me know if you need more details.
Guys, I really need some help with XMP Ram😢
While im turning it on, my computer started crashing in games etc
What should i do to fix that?
Hi. First make sure that XMP is causing the crashes because rarely does. When you establish that XMP is the problem, you can manually tweak the speed, latency and voltage of your memory until is stable. You can find many guides of how to tune memory in youtube. Or you can just disable XMP because you are not going to see substantial difference in gaming performance anyway.
@valentinosgsxr Thank you for answer! A couple of days ago, I built myself a new computer with an i7 14700k, 4080 super, an msi z790-p wifi motherboard and xpg lancer blade ddr5 16 GB (x4) 6400 GHz RAM. But in a regular mode, it runs at 4000 Hz. I tried running on xmp and got black screens in cs2. After turning it off, everything started working fine. I assume that this is exactly the problem with xmp, maybe I really need to adjust the voltage parameters and other things for them?
@@valentinosgsxr and another question, could this be related to different batches of RAM? I took 2 sets of 2 RAMs in each.
This is a good question. The answer you can find yourself. Since you are confident with building a system, just try remove two of the sticks, enable XMP and see how it goes. You don't need 64Gigs of RAM to play cs2. Let me know how it went. And yes, it is possible that 4 sticks of two sets to be unstable especially if they are of different chipset manufacturer.
@@valentinosgsxr bro, can you please explain to me why you set ac and dc to 10? Is it safe? What are they responsible for?
Will that effect the preformence for my cpu?
Just did it and faced lof of issues like screen blinking and crash without reaching high temp
Will not try this again
Motherboard: msi z790-s pro wifi
Once you fix the instability, performance should improve. To fix the instability you need to reduce the negative offset. This is the 0.150 you punched. Lower this to 0.100 and see if this working. Lower more, until your system is stable.
This drastically reduced performance in cinbenech from 34k to 23k same settings as yours
You should have punch something wrong. Double check your settings or better do them again.
This can happen if your AC/DC loadlines are too low for your selected Loadline Calibration curve. Also take it easy with the offset. Start from 0.070 and work your way up. Let me know.
Yea 0.150 offset got me blue screen so I had to reduce it to 0.100
@@Slaven-e6b I had to drop to 0.140 when I flash the 0x12B microcode to make it stable again. Good to hear you figured that out.
@@valentinosgsxr it runs fine now, and the temps are okay, went from 95c to 55-70c in games
Cooling?
Whatever cooler can handle 250Watts should be good enough. All 420 and 360 and 280 AIOs are OK. Some 240 may be good enough as well but most are not. I wouldn't cool any CPU that's capable of running at more than 160Watts with an air cooler.
Hello! I have the same motherbord and cpu. 12b microcode, I tweaked nothing but memory xmp to 6400 mhz and while gaming p-cores run at just 4200 mhz instead of 5500 mhz.(for a few seconds 5500 mhz but it goes back to 4200 mhz)) How many is your p-core clock while gaming? Thanks to your answer.
That's what TVB is doing. It is normal for stock settings. If you under volt correctly it should stay at 5.5 GHz during gaming.
Thank you! @@valentinosgsxr
for latest BIOS 09-26-2024 7D91vHE1(Beta version) still the same settings ?
Haven's try it yet but I believe the same settings will work. If not, they will only need some small modification. I was thinking to flash the new BIOS after it comes out of the BETA state. If you re not willing to try yourself I may try it tomorrow.
@@valentinosgsxr i have the same motherboard and CPU, but 64Gb Ram and AIO LS720 360mm but have:
Max CPU package power = 241 Watts, maybe due to of RAM size
Max Core VIDs = less than 1.2 Volts
Max CPU package Temp = 78 stable (80 max)
So idk looks like last BIOS have some changes in Max Core VIDs by default and also why i have much more Temp than u ?:(
i did the same BIOS setting like in video
@@googlerdoodler458 All numbers are looking good. I wonder what is your multicore score at R23. The difference in Package Power is margin of error and it is explained by the VRMs tolerances and the overall tolerances of the motherboard. Also the higher temperature is slightly increasing the power consumption and this is normal. Less VID request, again is margin of error. 80C for full load is a great result. The package temperature varies according to the current ambient temperature. I am also using a 420mm AIO in a full tower case. Happy to hear that my video helped, that was the sole purpose.
@@valentinosgsxr
R23 score: 36248
Happy to hear that numbers are ok 😄 Thanks for your efforts 🤝
Hi! On gigabyte bios where can i do this settings? doesn t match with yours
Hi. Loadline calibration curves are related to the motherboard's hardware and it wont work the same. Offset tolerance mostly depends to the CPU so you can always try the offset method. No, you can't punch those settings straight to your motherboard and expect it to work the same but all the settings are there under different menus and names. You need to find a guide for the particular motherboard/CPU compilation if you don't want to experiment your self.
Hello! I did everything the same as you did in the video, but for me the p cores only run at the frequency of the e cores, so the p cores only run at 4200 mhz. I think the cpu is faulty because I did a stress test with a weak cooler and it was often at 100 degrees. Before the stress test, the p cores were working fine at 5500 mhz. What do you think?
Hi. It is possible that you damaged the CPU running it with insufficient cooling but the symptoms usually are crashes, restarts and blue screens. If you want to troubleshoot further, I suggest you run cinebench R23, monitor with HWinfo and take notes of maximum effective clocks, max CPU core temperature, max VIDs and max Vcore as well as your score and let me know. You should also lower the offset because 0150 is extreme for most CPUs and cinebench might crash.
@valentinosgsxr Next week a 360 mm cooler will come and I wiil try. But I ran cpu health program and everything was ok including cpu clock. If I'm playing and stop the game and open msi center hardware monitor it shows 5,5 GHz but when I continue playing clock goes back to 4,2 GHz.
@@ferencdavid1763 Well, depending on how this game is scheduling the CPU usage, the 4.2GHz could be normal behaviour. It also depends of which values you are looking at. Effective clock rate is usually lower than the targeted clock rate. I am suspecting that your CPU is just bored during gaming having not much to do, but this is easy to be proved by benchmarking.
@@valentinosgsxr The cpu usage 10-15% it drives 3070 ti in 1080p but before stress test the cpu ran 5,5 GHz under games. And under every game it runs only at 4,2 GHz. But I will inform you after test next weekend after installing the New cooler.
@@ferencdavid1763 Yes please, let me know. Hope it will work out for you.
do you keep your system like this or is it just for testing? and xmp always on? thanks!
This is how it runs since new (give or take due to too many BIOS updates) and this my daily gaming PC. XMP is 100% stable for me so its always ON.
@@valentinosgsxr hi man. So i should tweak the setting like your after my bios update ? Running the same cpu like you but with z7790 tomahawk max wifi.
@@UfrxhEdi Hi. I haven's flash the 0x12B yet but according to intel it is just a summary of the previous microcode fixes. So yes, I believe nothing is changed in that regard. I would definitely recommend you to under-volt no matter the BIOS version. My settings are very likely to work for you as I also run a Z790 tomahawk in this system. Let me know how it goes... I will probably flash the new BIOS when it's out of its BETA state, just because I m sick and tired with the pushed BIOS' that change very little anyways.
@@UfrxhEdi I may didn't express myself correctly to my previous comment. What I was trying to say about the motherboards is that MAG and MAX they share the same VRMs so the under-volt settings should be comparable.
@@valentinosgsxr Hows been the new microcode 0x12b treating you?
I got the asus ROG STRIX Z790-A GAMING WIFI motherboard and clueless on how to do this shit since i have the i7 14700k. Intel need to screw their heads on.
You don't have to under volt your CPU if your system is running OK. If you choose to do so, just do the offset tweak and leave the rest alone. The settings are there but in different menus and similar terminology (if not the same).
Hi. If you still haven't figure out your settings, I found a guide here on youtube with a very simple method to get voltages under control, only withdraw is that you are leaving around 10% performance on the table. Check it out: ruclips.net/video/DYDwh9ugTew/видео.html
hey bro ,can u send me your discord tag, or upload new video on this, or can i follow this same settings
Hi, I don't have a discord tag. What would you like me to upload? If you are on an MSI Z790 I definitely recommend you to follow this guide and test your system. Just don't go for 0.150V offset straight away because "silicon lottery" is a thing and the tolerances are slightly different from CPU to CPU.
