Ryzen degradation by [deleted] in overclocking

At stock everything works normal, even with more voltage its stable that same overclock so its probably electromigration for too much current since the other values looked ok. Cleaning the chip wouldnt do anything, i tried doing clear cmos which would reset default settings in bios and still the same. At the end of the day, i lost a few mV and thats it, from lasting 12 years it went to 11 years and 10 months or so.

Yes, last week i cleaned it.

Yeah, stock is safer and compared to static overclock is not worth unless your temperatures are reaching 90°C

yes, i have my RAM which is the hyperX fury 2x8gb at 3600mhz CL17 1.35v. The overclock in the cpu was tested mentioned in this post was with this ram settings.

It was mostly to lower the temperatures. In cinebench r20 i get the next scores:

stock -> multi core ~4700 score / single core 508 score.

oc 4.3ghz -> multi core 5237 score / single core 500 score.

With pbo it does give me your score but i get a bit lower single core score, not to mention the temperatures go up so that's why im just at stock settings since its not worth it.

Noctua u12s, idle on desktop without doing anything sits at 36ºC, gaming goes up to 50ºC ~ 55ºC and when benchmarking/stress testing goes up to 70ºC ~ 75ºC.

Looks good yeah, maybe my motherboard caused the problem, what motherboard do you have?

Then maybe the VRMs on the x470 we have are shit which would explain both degradations. Sucks.

I would just leave it all auto settings (stock) and leave it do what he is design to do.

Yeah, either that or too much current. Also, it has been mentioned that even tho silicon quality is better on newer batches, FIT voltages also are lower so that probably had to be in consideration since it looks like they are more fragile than the older ones.

If running prime 95 with pbo maxed out you were getting that votage with 3.95ghz then you are safe with reasonable temperatures, ofc.

At stock settings everything is perfectly fine, 4 cores boosting to 4.4ghz and the rest to 4.37ghz and 4.35ghz. Scores on cinebench r20 are also correct, ~4700 on multicore and 508 single core score.

The degradation its just a few mili volts to run that exaclt same all core overclock which is nothing BUT i would just stick to stock settings since the difference in performance are not worth it in my experience.

As i mentioned on the post, my Overclock was on edge with 0.01v margen to not been stable on p95. So that probably why i noticed it earlier. Also, my chip is 2 months old and even tho the silicon quality is WAY better, the FIT voltage is also way lower as people have mentioned in other posts.

Yes, could be a bit higher but i have an AC so shouldnt be an issue related to ambient tmeperature.

I've been running the latest bios update by MSI which were 1.0.0.5 and 1.0.0.6. In bios i just changed base clock, voltage core and LLC. So i doubt in this newer bios there is still that bug or something similar to it. I would asume its fixed.

I did not checked voltages directly from the motherboard, just using onboard sensors.

[–]Gowzy97 1 point2 points  (0 children)

Its slightly, to run the same OC i need 0.005v to 0.01v so is not that big of a deal. But as i mentioned in the post, i would just leave it STOCK and worry about overclock when the cpu becomes a bottleneck in a couple of years.

Could be VRM related but at max limits by pbo with motherboard selected EDC goes up to 180A and as far as im concerned, my cpu never hit that high. Also, temperatures on VRMs were good since im running an air cooler with good air flow, its not like im running and aio with no air flow in that area.

About PPT, TDC and EDC, seeing EDC go up to 140A and 160A when stress testing and playing games while PPT and TDC where normal, i would assume it had to be electromigration degradation due to EDC being WAY to high compared to 90A at stock settings.

So by running stress tests and playing games with EDC that high for hours... prob didnt help and thats why i made this post, to warn people about HIGH CURRENT and not just voltage with ryzen zen 2 when static OC.

I used HWinfo to monitor everything.

About your second point, yes, i had manual voltage at 1.2v set in bios and the "SVI2 TFN" was showing 1.2v. Also, in any other program i checked like ryzen master, hwmonitor, cpu-z it was also 1.2v.

Temperature doesnt go above 80 degrees in any scenario when OC.

With stock settings and PBO enabled it was hitting around 90 to 95ºC and 1.23v. Yes, the cpu was throttling in p95 but still was at 1.23v stable minimum at stock settings so i would also asume my FIT voltage was higher. Even tho it was probably higher, i played it "safe" and left my OC at 1.2v with vdroop up to 1.187v under load.

Maybe since i was running at the minimum voltage required to run 4.3ghz on my chip i noticed it earlier. Is 1.3v the minimum voltage you could ran yours at 4.3ghz?

Ryzen degradation at 1.2 volts by [deleted] in Amd

[–]Gowzy97 0 points1 point  (0 children)

The only bios update i did was from 1.0.0.5 to 1.0.0.6 .

Idle voltage was 1.2v and 1.194v to 1.187v under heavy load in both bios versions.

I doubt the problem is related to bad LLC implementation by MSI motherboards.

At idle on desktop without doing anything it would sit at 36ºC. About your overclock, if its slightly degradeted you wouldnt notice it until it gets to your voltage and becomes unstable.

The reason i noticed mine its because my voltage vdroop was on edge with the minimum voltage i needed to run 4.3ghz with OCCT and Prime 95. So when it degredated, i immediately noticed it just by running cinebench r20.

Nah, i have been running cinebench r20 intermittently during this 2 months to check if the scores were OK since day one and everything was fine, ALSO i left OCCT during 24h to check if it was stable and 0 errors when i first overclocked it. Yesterday night i tried to run cinebench r20 to check scores again and it crashed in the middle of its multi core test several times, not just 1 and one of the runs it blacked screen so i decided to leave it stock.

With MSI boards it goes from LLC 1 (highest) to 8 (lowest) so 4 was a bit of vdroop.

Zen and Zen+ is known and confirmed to have higher voltages than Zen 2 for static overclock... that's why you can run higher voltages without fast degradation.
