CPU VID going above 1.55V despite 0x129 update?

Gessler — Sat, 17 Aug 2024 13:39:35 GMT

I have a i7-14700K and just updated my Asus ROG STRIX Z790-E Gaming WiFi II board to BIOS 1503 which contains the 0x129 microcode update.

When doing a 30-min Cinebench R23 test, I've noticed in HWiNFO64 that I had a peak VID of 1.565V! Isn't the new update supposed to prevent this? HWiNFO confirms that I'm on microcode version 129.

My BIOS is set to Intel Default Settings (hitting F5 sets to defaults). PL1 & PL2 are at 253W, ICCMax at 307A, MCE is disabled & SVID is set to Auto. My Loadline Calibration was set to Level 4 by default. XMP is disabled.

I've noticed that peak VID stays at or under 1.500V for the first 20 or so minutes of the test, it's only in the last ~10 minutes that the peak VID value seems to climb. Is this a result of the voltage accumulation bug that Intel talked about in their latest official communication?

Requesting some guidance here as to what I should do.

Asking again if someone can help with my situation.

I've noticed on the 0x129 megathread that there was another person who's VIDs were also going above the 1.55V limit despite applying the update.

This might be a serious issue/bug that needs to be addressed if it's effecting a lot of people. Most of those who apply the update may not even know to check things like HWiNFO for voltage request behaviour.

I actually had the same problem except that my vcore had climbed to 1.71v! I did an RMA of my 13900k, the processor was already damaged unfortunately. You should do the same.

Was the 1.7V before or after applying the 0x129 update?

après la mise à jour. Soudain, mon processeur s’est mis en étranglement.

The bios are still in Beta stage so we should wait for the final version perhaps

That is indeed weird.

The maximum that I've seen my Vcore go was 1.518V however I continue to get VID requests in excess of 1.55V, which is something the new microcode should specifically stop from happening.

To my understanding, if the CPU has already degraded to the point where it needs much higher voltages to work, it should simply crash/fail to boot as it becomes unable to request the voltages it wants due to the supposed 1.55V cap. But it should not continue to ask for higher voltages.

I think there are two different issues here, both serious.

EDIT: In my case, I have not noticed any difference in Temperatures or VID behavior before & after the update. Just that the update was supposed to stop 1.55+ VIDs but it's not doing it.

I have blue screens, crashes in games, applications and web services. This is why I made an RMA (accepted within 3 days after discussions with support). For computing and with the same components they will work differently from one PC to another. these are the joys of computing

The BIOS are progressing out of Beta stage at varying rates for different motherboards. In my case, I only downloaded & applied it after it had come out of Beta.

Did you get the replacement CPU yet? If so, how is the voltage behavior on the new one?

My processor arrived at Intel Holland. Mine should arrive (the new one) next week. For the moment I'm running on an i3 12400f, what a horror

As soon as I receive the new one I will keep you informed of tensions and others.

Thank you, please do tell me if the new CPU manages to stay under 1.55V VID (not Vcore) during a 30-min Cinebench R23 test if possible.

You will have to stress test the new CPU anyway to ensure that you did not get a faulty one.

Yes I will do that and I will keep you informed. It was nothing, with pleasures.

I received a 14900k in rma from my 13900k. I start, go to the bios (bios 0x-129), I start under windows (10x to be honest), blue screen, black screen, impossible to launch a game because return to the windows desktop. Drivers up to date, Windows 11 reinstalled, my cpu when I can test it is below the 13900k! I tested memory by memory, computer restarted, black screen, blue screen, unstable (voltage of 1.44v however and temperature at 44 degrees at rest). I'm stuck there...

That's unfortunate. But thanks for providing the upate on your situation!

If you have ruled out all other variables, it would appear the 14900K you received was already degraded/faulty. Unfortunate that it wouldn't remain stable long enough to test in Cinebench or gaming to see if it was at least sticking to the 1.55V limit or not.

At this point, I'm afraid you only have two options: Tell Intel that the CPU you received is unstable and seek a 2nd RMA, and hope that you receive a good one this time. OR, seek a refund for your original 13900K and use the money to buy a new 12900K/KS which should be safe from these issues.

Down the line, you might be able to upgrade to a Bartlett Lake CPU. This whole thing has been a mess!

I just put my RAM by default without XMP, the computer starts, I arrive on Windows, nickel. I launch a game, it starts then cuts. I launch another game, it starts then cuts. I launch cinebench, it starts, I press multicore test, the test cuts. I arrive. launch cpu bench and intel extrem bench, point = 4780 I restart cinebench, miracle it starts in multicore test, I do 1 pass, result I am below an i7 7700k !!!! I restart cinebench, 2,3 passes then blue screen. I reinstalled Windows (tried because blue screen during installation). A friend arrives, I test his 12900k and a 13900k, no worries. 40 years of computing and now I'm completely stuck. I don't know what to do and I've been building PCs for 40 years. I RMA'd the 14900k and asked for a replacement with a 12900KS. We'll see. To be continued...

Para mim também, a tensão esta mais alta depois da atualização da Bios
