Easy to follow explanation, yet deep enough to help me continue working on optimizing parameters for my 7950x having a very diverse cores quality (some allow for -30, some not even a -1).
Are we witnessing AMD letting all the popular RUclipss and other media outlets posting benchmarks with the early, higher-clocking versions, just to then dial down everything over time for the consumer as to keep warranty claims in check ?! .. just saying
Great explanation, this probably wont have a huge impact for most people, but it means people who likes to OC to get the very best performance will have a to work a litle bit harder. This is not thew first time AMD, Intel or Nvidia does this kind of adjustments for a recently launched product.
Hmm I saw the prior video and encountered that stuck at 5.5ghz. I decided to just forget about it and enjoy a -30 curve optimizer offset. Its been stable and I get cooler temps. It just seems like a pita to attempt all these setting changes to work around the limiter.
Sure it's annoying, but if you do anything beyond overclocking for the sake of looking at charts, the real world impact is pretty much zero. Clocks in encoding or rendering would never reach that high anyways.
7950x still boosts to 5.7 Ghz when up to 3 cores are loaded. This limiter only kicks in when 4 or more cores are loaded. Besides, with most workloads you are likely to trigger other limiters such as temperature, current, etc. long before you trigger the C-State limiter when 4 or more cores are loaded.
I noticed this "Boost It" feature 2 days ago... I was really annoyed when I was stuck at 5550, enabled it... 7700x is now running 5750MHz on light and medium loads
Wonder what this is called in MSI bios.. my 7700x will hit the higher core clocks randomly cause I see it on HWmonitor... But even prime 95 one core never goes that high...
i have a x670 gaming x ax and a 7700x cooled by the arctic liquid freezer II 360mm with offset mounting for amd, i managed to set the curve optimizer to a stable -30 and frequency offset to +200, before enabling global cstates and disabling spread spectrum when i ran cinebench at all cores i got 5.3ghz at 87C and single core 5.47ghz at 55C, after enabling global cstates and disabling spread spectrum it runs 5.45ghz at 87C and 5.55ghz at 55C even though it has a lot of headroom in single core tasks it still doesn't boost above 5.55ghz
@@pinkipromise its been a long time since i made this comment, the one weird thing is that it somehow spiked to 5,8 ghz in 3dmark(which should be impossible on pbo because the maximum should be 5.75), i think that there is still no solution to it not boosting. As for scores obviously they're higher because I optimized everything (cpu, ram, gpu, os) it also has lower power draw and temperatures
With pbo2 +200mhz 10x scalar -30mv all core and medium load boost it, in game most cores were on 5.6 some on 5.7 and 2-3 on 5.8ghz.. max were hitting 5997 on most cores on some 6.1-6.2ghz (7900x)
11:00 this video is key for me right now!! I’ve been using AI overclock mode in my x670e, coupled with PBO and curve optimizer at -5 and per core. I have learned about medium boostit through the AI setup. I have disabled the c state control though… I have this on my 5950x pBO setup so I think my thought was mimic that setup. My issue is SSE benchmark. Passmark SSE will immediately spike my tdie to 110c, but normal operation and max on hwinfo is not above 96c. I have seen 5.9 and 5.8ghz. There is definitely a voltage spike with SSE benchmarks both Passmark and OCCT will shut down the pc, not a reboot, it will shut it down, however I can do 10 and 30 minutes tests on cinebench R24 with no issue and very reasonable temperatures. AI uses dynamic overclock switcher, so all core is 5.3 and 5.2 on ccx0 and ccx1. I think with boostit maybe I should just fine tune my per core optimizer instead….my issue there I think is core 1 and 5 trying to push more than -5, I think that will be my next fine tuning plan of attack. Thanks for this video!!
What is the real explanation of the last line, boostit Tuned? Mediumnload boostit does nothing for my board and 7950x3d on the performance cores. Still 5.5ghz. I’ve seen 5.8ghz when I first bought it.
Hi, I have a Ryzen 7600x + B650 Aorus Elite. Could you do a manual overclock tutorial with dynamic v-core? because with PBO I can't go beyond 5,500mhz and I don't want to leave it with V-core at maximum 24/7 either. The ideal is to reach 5600mhz.
Interesting, so this is just impact the performance on 5-8 threads? Graph on CPU profile is just run variation I assume? (Under 1%) Have you check on other SKU? Like 7700X for example. Can we have the NOPbench? :) Thanks Massman!
The impact is from 5 to 16 cores. You can see it more clearly when PBO tuning is involved skatterbencher.com/wp-content/uploads/2022/10/Slide7-1.png. The real-world performance impact is limited because ... well, it takes quite a lot to be able to run >4 cores above 5.5 GHz. Good CPU, good cooling, light workload, ... Most of the CPU Profile graph can be explained by run variation, yes. I included it to demonstrate limited real-world performance impact. Other SKUs have the same limit, yes (checked 7600X which also capped at 5.5G). NOP Bench -> check with Elmor in his discord :)
@@SkatterBencher I say 5-8c load because that's where the clock gracefully decreased vs directly clocked down to 5.5G. the rest (9-16) is the same behavior with default. At least in this video. Yes Maybe there's some samples with adequate cooling that can surpass this. I remember PBO on Zen4 is scale with cold, at -30 - -60C LN2 pot, I get the 7950x run cinebench @ 5.8G automatically. Thanks for the explanation! Will look to Elmor discord later. 😃
@@SkatterBencher the only time I see more than 5.4 all core is in Aida64 stress test. It’s also the most reliable one (cache disable) to test the curve optimizer when selecting affinity to each core
My asrock- x670E steel legend doesnt have A syncronus (eclk) or bclk .. so basically what other options are their to get around 5.5? I mean without manual oc. its unfortunate because my 7600X is doing All core 5.5ghz prime95 @ sub 60*C so much headroom but not much to do with it.
And here I am with my 7700x on a MSI B650 motherboard, unable to get past 5500MHz which prevents me from increasing my 3dmark Port Royal score... that sucks. There is no workaround on MSI motherboards yet it seems...
My 7700x still boosts to 5.750 GHz on 6 cores when doing nothing lol. Kinda pointless tho. It's mostly stable on 5.5 GHz so effective clock is 5.5 GHz.
When do you make a deep video on how to stabilize CPU with MLB and boost clock limiter ? My 7950X is so bad that I can’t stabilize with MLB…whatever I do.
I have a 7950X at work and it is driving me crazy. It boosts to 5.85GHz on CCD0 and 5.5GHz on CCD1 when not under full load. When its under full compute load, its boosting to 5.4 and 5.2 while maintaining 80°C. (SMT disabled, my compute software cant use it and loses performance sometimes) there is thermal headroom and i cant use it. The BIOS with asus options and AMD Options is horrible. Undervolting behavior per core is terrible... Dont get me wrong, performance is great, but the behavior is strange
Well I can’t even use this to help me get past 5.5GHZ as I used to be able to before I updated my bios. This is only applicable to people on higher end boards. My Gigabyte B650 doesn’t have a “medium load boosit” setting and no “eclk mode asynchronous mod” setting either. I guess I lost performance just by updating my bios!
I already put up a video with the 7900X and the Crosshair X670E Extreme ruclips.net/video/o_AMxVcS2DM/видео.html I don't have any plans to also do a guide with the Hero.
@@SkatterBencher Can you do a tutorial for the 7950x3d when it comes, with PBO? If it was on the Strix x670-e E gaming wifi, that would be even better haha!
Two weeks ago got 7950x for 550eur and asrock b650e pg riptide wifi. And now i noticed that yeah CPU does not boost above 5.5ghz, even if i set pbo +200 with negative offset -20, its not going above 5.5ghz, even if i set negative offset. Asrock board bios does not have asynchronous mode, or i just cant find it. Also no boostit mode either. Any ideas or it is what it is and, i should cope that 7950x is underperforming.
13700k 5.6ghz 8 cores, 5.7ghz 7 cores and we chillin. I'm glad I chose this over similar priced 7700x. This thing is more in line with a 7900x and gets too close to a 7950x for it to be nearly half the price.
@ScatterBencher, my 7950x (with decent cooling via Lian Li AIO Galahad 360) cannot safely use any curve undervolting beyond -5 or -10 without setting the boost clock lower. I can reach -30 C.O but must set my boost clock to -325 MHz to be stable on long duration load tests. I cannot even boot my PC at -30 C.O without at least a -175MHz override. Does this indicate a bad CPU?
I've seen a CPU like this before and, yes, it was just not a silicon lottery winner unfortunately. What you can try is use Per Core curve optimizer to isolate the core that's so terrible. If you're lucky, maybe it's just one of the CCDs that's bad and you can do a big CO on the cores of the other CCD.
@SkatterBencher interestingly I can run all cores at 5200Mhz no problem with -30 but single is sort of stuck at 5400. Temps are great and wattage is low so not a bad compromise but not quite the lottery winner as you said.
@@SkatterBencher Update: With some additional tweaks and moving my 6 intake and 3 AIO exhaust fans to full speed, I can run all cores at 5280Mhz with a -30 curve on all cores but I had to bump down a touch more on the boost clock which is now at -350MHz, so 5500 + 350 = 5850.... i'm just not sure where that 5850 number comes from. With that said, I'm not complaining about a 39150 Cinibench R23 multi-threaded score. On the other hand, single-threaded tests top out at 5407 despite the max being listed in Ryzen Master as 5500MHz as noted above and single-thread temps at only 49 to 53C. Overall, this is not a bad compromise, especially when you consider that my idle temps are 42.3C (which is pretty cool for a 7950x) and power usage is also low: idle < 3.0 W, single-threaded < 12 W, and multi-threaded < 180 W.
If you are using an MSI or ASUS motherboard (High end only), try setting the VRM switching frequency to 900 or 800 or 700KHz. Also try turning Spread Spectrum ON/OFF. Normally, there should be almost no change, but if there is a significant difference in stability, there is a possibility of a BIOS bug.
Overclocking these days doesn't have the impact on real performance like it did 20 yrs ago .. This is how a 55 yr old guy thinks.. I just spent 1000 bucks just on a processor and motherboard i sure ain't gonna tinker with it lol.. Who cares if you get 200mhz out of it
Does anyone know why is that on the asus motherboards that you can adjust PBO2 at two places? I set both of the mfor the same to be sure but it's just weird. Thanks
The PBO options exposed in the main ROG menu (Extreme Tweaker or Ai Tweaker) are copies of the AMD menu items you can find in the Advanced menu. You can control PBO using either.
Hello again ^^ It's pretty weird i got better results when i'm stuck at 5.5Ghz than up to 5.750Ghz oO I used PBO2. Up to 5.75Ghz (MLB enabled): Prime95 => 5.29Ghz 92C° - 205W Cb23 => 5.4Ghz - 84°C - 163W - 20600pts Assetto Corsa => FPS AVG 466 - FPS MIN 415 Up to 5.5Ghz (MLB disabled): P95 => 5.250Ghz - 67°C - 145W R23 => 5.5Ghz - 71°C - 21000pts Assetto Corsa => FPS AVG 468 - FPS MIN 428 And for the record, C-State enabled has reduced my perf.
Got an 7950X + Gigabyte X670E Aorus Master. Unfortunately, with default settings, the CPU hits 95°C on a 420mm radiator pretty much instantaneously when in Cinebench R23. Idle around 41°C in Bios, 49°C in Windows. Went with the PBO undervolt + overclock tutorial that led me here and now I am stuck with 5,5GHz, much lower temps, but cannot boost past 5,5. What exactly can I do? I already have C states disabled from the beginning without success and I only find a "Async CPU/PCIe clock" setting that can only be turned on and off. Help please?
C-States should always be enabled on AMD platform. When more cores are in the lowest C-state, the others can boost higher. Regarding the 5.5G, I'm not sure if there's another workaround on the GIGABYTE BIOS than using eCLK. As for the Async eCLK: can you not enter the eCLK frequency, set Async to enabled, then increase the eCLK to further increase the CPU frequency?
@@SkatterBencher If you use Async, wouldn't that affect everything on the PCI-e bus ? Such as videocards, soundcard, even M2 SSD ?? Your videos are good, well presented, and informative. The only issue I have is your use of a motherboard that is most-likely out of reach of us mortals, such as your ROG CROSSHAIR X670E EXTREME - that is a £1000 quid motherboard, nobody buying a £300 CPU such as the 7700x is going to then buy a £1000 motherboard. Perhaps, have a few videos using a more affordable motherboard ? I mean, the AM5 boards are already too expensive as they are.

If you want to re train your timings for best performance it’s a slow boost time and my 7950x without GPU load system load 465 watts before it gets thermal throttled down to 410 watts. That’s with an undervolt. So honestly AMD will pull nearly 500 watts system load

@SkatterBencher interestingly I can run all cores at 5200Mhz no problem with -30 but single is sort of stuck at 5400. Temps are great and wattage is low so not a bad compromise but not quite the lottery winner as you said.
@@SkatterBencher Update: With some additional tweaks and moving my 6 intake and 3 AIO exhaust fans to full speed, I can run all cores at 5280Mhz with a -30 curve on all cores but I had to bump down a touch more on the boost clock which is now at -350MHz, so 5500 + 350 = 5850.... i'm just not sure where that 5850 number comes from. With that said, I'm not complaining about a 39150 Cinibench R23 multi-threaded score.
On the other hand, single-threaded tests top out at 5407 despite the max being listed in Ryzen Master as 5500MHz as noted above and single-thread temps at only 49 to 53C.
Overall, this is not a bad compromise, especially when you consider that my idle temps are 42.3C (which is pretty cool for a 7950x) and power usage is also low: idle < 3.0 W, single-threaded < 12 W, and multi-threaded < 180 W.
If you are using an MSI or ASUS motherboard (High end only), try setting the VRM switching frequency to 900 or 800 or 700KHz.
Also try turning Spread Spectrum ON/OFF.
Normally, there should be almost no change, but if there is a significant difference in stability, there is a possibility of a BIOS bug.
Where can I get the Elmor Nopbench tool?
Ask Elmor on his discord channel discord.com/channels/514312075686838282/781527795633094717
Where to download nopbench software?
You can always ping Elmor on his discord channel (though he's got a lot of products coming out so he's pretty busy)

Thanks for the explanation . I hoppe they remove this bs. soon.
Overclocking these days doesn't have the impact on real performance like it did 20 yrs ago .. This is how a 55 yr old guy thinks.. I just spent 1000 bucks just on a processor and motherboard i sure ain't gonna tinker with it lol.. Who cares if you get 200mhz out of it
Does anyone know why is that on the asus motherboards that you can adjust PBO2 at two places? I set both of the mfor the same to be sure but it's just weird. Thanks
The PBO options exposed in the main ROG menu (Extreme Tweaker or Ai Tweaker) are copies of the AMD menu items you can find in the Advanced menu. You can control PBO using either.
@@SkatterBencher ah I see.. Thank you
My 7700x would hit 6ghz now its stuck at 5.55
To be honest, without delidding we are thermally limited either way. It’s just how that thermal envelope is filled
I hit 5.4 all cores with 1.22 volts at 85c
I hit 5.48 all on 7700x with arctic 420 and co -30 setting. 82° max.
Hello again ^^
It's pretty weird i got better results when i'm stuck at 5.5Ghz than up to 5.750Ghz oO
I used PBO2.
Up to 5.75Ghz (MLB enabled):
Prime95 => 5.29Ghz 92C° - 205W
Cb23 => 5.4Ghz - 84°C - 163W - 20600pts
Assetto Corsa => FPS AVG 466 - FPS MIN 415
Up to 5.5Ghz (MLB disabled):
P95 => 5.250Ghz - 67°C - 145W
R23 => 5.5Ghz - 71°C - 21000pts
Assetto Corsa => FPS AVG 468 - FPS MIN 428
And for the record, C-State enabled has reduced my perf.
yeah man i just LOVE hardware that doesn't listen to me thanks nvidia geforce, radeon, and zen.
Revisit🎉?
Should do at some point since it looks like the limiter is not present on AGESA 1.0.0.5 :)
@@SkatterBencher Would love to watch that pretty soon! Thank you!
@@SkatterBencher Yes please Sir!
Mine crashed.
this craziness AMD has done should give everyone option for a full refund
Got an 7950X + Gigabyte X670E Aorus Master.
Unfortunately, with default settings, the CPU hits 95°C on a 420mm radiator pretty much instantaneously when in Cinebench R23. Idle around 41°C in Bios, 49°C in Windows.
Went with the PBO undervolt + overclock tutorial that led me here and now I am stuck with 5,5GHz, much lower temps, but cannot boost past 5,5. What exactly can I do? I already have C states disabled from the beginning without success and I only find a "Async CPU/PCIe clock" setting that can only be turned on and off.
Help please?
C-States should always be enabled on AMD platform. When more cores are in the lowest C-state, the others can boost higher.
Regarding the 5.5G, I'm not sure if there's another workaround on the GIGABYTE BIOS than using eCLK.
As for the Async eCLK: can you not enter the eCLK frequency, set Async to enabled, then increase the eCLK to further increase the CPU frequency?
@@SkatterBencher If you use Async, wouldn't that affect everything on the PCI-e bus ? Such as videocards, soundcard, even M2 SSD ??
Your videos are good, well presented, and informative. The only issue I have is your use of a motherboard that is most-likely out of reach of us mortals, such as your ROG CROSSHAIR X670E EXTREME - that is a £1000 quid motherboard, nobody buying a £300 CPU such as the 7700x is going to then buy a £1000 motherboard. Perhaps, have a few videos using a more affordable motherboard ? I mean, the AM5 boards are already too expensive as they are.
Medium load boostit is BSOD and crash fest.
Class action incoming.
Makes their 5.7 claim completely false
7950x still boosts to 5.7 Ghz when up to 3 cores are loaded. This limiter only kicks in when 4 or more cores are loaded. Besides, with most workloads you are likely to trigger other limiters such as temperature, current, etc. long before you trigger the C-State limiter when 4 or more cores are loaded.
@@bgtubberI'm running the 7950x With a 360mm corsair AIO and With an undervolt of -15 all core and for every games I play even at 4k the cpu is completely limiter at 5.5ghz in games... it run great but we bought this CPU to run at the frequency of the first reviews and on the box!
@@gunzorkgaming7847 Hi. Did you do the BIOS update which introduces the limiter? If you did, do you see a decrease in performance?
@@bgtubber I have the lastest bios update and my system is New so i cannot tell you i saw slower performance than before. But my single core performance in bench Never match any of the reviews of the CPU when it came out.
Glad I returned my 7950x before they gimped it. With the much higher platform price, long boot times and idiotic 4mm IHS I'll happily throw away energy for my i9
Long boot time? How's so?
@@JoeMama-yl1ow it's good for the winter lol
@@linearz I just had poor experience with boot time, even with the Asus specific "retain ram config/training" option vs the 13600k system I built my partner. More like 3 seconds on that rig vs 15-20 for AMD to post. Minor, but it adds up considering platform cost vs the competition
If you want to re train your timings for best performance it’s a slow boost time and my 7950x without GPU load system load 465 watts before it gets thermal throttled down to 410 watts. That’s with an undervolt.
So honestly AMD will pull nearly 500 watts system load
@@JoeMama-yl1ow oh you don't throttle? So you are holding a solid 5.6ghz + on all cores with 6ghz PBO? If so congratulations on your cooling solution as I can't do that here I'm this warm weather.
Because AMD is trash
Naah not really. GPU's r another story
In all of your tests you are temperature limited, I have delided my 7700x and max temp @ all core 5,55Ghz = 78c
Mine boosts to5.9 all the time according to gpuz
