So yea + 0.06v is kinda allot for ram and potentially unstable for non bdie
While all other volt settings give slightly lower..

Flashed to F31, didn't change anything for me, still cant post past 1800flck, went back to f30. Suddenly a ton of WHEA Errors in my event log even though i have previously been stable at F30 with an 3600mhz/1800flck overclock for over a week.
Even setting things down to 1333memory with ultra loose timings and 1333flck stock flck the whea errors remain. Disabling core performance boost does take away the boosting but WHEA errors remain. Went back to f31 as f30 is no longer stable but errors remain.
Only when i set a static multipiler for my CPU other then the default 34 will the WHEA errors go away, right now i run a multipiler of 38 and the cpu is running all cores at 3800mhz, i set memory back to 3600 and flck to 1800 and i have zero whea errors.
My idea is that when i flashed to the F31 bios there was some hidden microcode in the bios that gets updated on the cpu chip, and even when you revert back to f30 that microcode remains in the cpu chip, and therefor even tho i flashed back to the my old stable bios f30 i am now having these whea errors.
What an absolute mess. I hope gigabyte can get this fixed, what can i do to push the agenda? Contacting their support seems to be sort of zero result, but i am thinking considering how many people are experiencing these WHEA errors and now me who previously had a fully working system for over a week now suddenly get them too my belief is that soon enough other people who have stable builds will get them when they update their bioses.
Hardware: 5950x
MB: Aorus extreme x579
Mem 4x16gb single rank 4000mhz cl19

Thanks for sharing your input.
Today my MSI B550m Mortar arrived and guess what. Everything now works as it should. No crashes after 4 hours of testing, gaming and using the system. Everything else is the same.
RAM runs at 3600 cl14 again. Didn't try going higher yet but I don't even care for now. Just happy it works.
Hope it's not a hardware issue for Gigabyte and that the Bios coming later will sort it all out. I'm definately keeping my MSI board though.

WTF is wrong with the F31 bios? Is this even safe?
My CPU is at 2volts!!!! Gigabyte will you send me money to buy another cpu? What are you doing with your bioses? This cannot be safe, i am literally not overclocking and you are pushing 2 volts to my cpu , the spec is 1.5volts, whats wrong with your egnineers? (See pic below, this was all stock settings, no voltages modified in bios). BIOS F31.
5950x.
EDIT: must have been a bug in hwmonitor, i closed the program and open it again and the voltages don't even look the same, there's no "VIN1" etc, i have no idea where those mesaurements came from, must be a bug in hwmon

@stasio: Please have a look at the issues with BIOS overclocking I'm posting below
Hi,
I posted a couple of pages back about my system being unstable, I've now had a bit of time to delve into the BIOS and settings and this are my results using the newest BIOS F31 for my X570 Aorus Pro Rev 1.2, Ryzen 5900x and 64GB Crucial Ballistix 3600-16-18-18-38 RAM:
First: RAM is stable on XMP profile, since BIOS F31n I've had absolutly no issues with my RAM
Second: "Core Performance Boost" in BIOS is still not stable, as soon as I activate this option I get BSOD with WHEA_UNCORRECTABLE_ERROR. Sometimes in less than a minute after boot, sometimes I make it ~30 minutes but the system is not usable productivly. With this options set to "Disabled" the system runs stable but all cores run at 3700MHz, basically crippling performance. I have not been able to achieve a stable system with this set to enabled, I've tried changing voltages up and setting Load Line Calibration, but no success so far. If anyone has more experience with voltage control I'm happy to get some pointers.
So, to get the performance I want out of the CPU I tried to manually overclock (or really clock since the package for the 5900x says maximum boost 4,8GHz) the CPU. Where I found some very wierd behaviour with the "CPU Ratio Mode" in the BIOS.
The all core overclock works fine but so far I've only managed to get it stable with 4,4 Ghz. Not bad for the all core performance, but lacking in single core. So I wanted to try the "CPU Ratio Mode" set to "Per CCX", thinking I can overclock 6 cores a bit higher and the other 6 a bit lower. The thing is, using this only every changes the clock for the first two cores on the CCX (attached images from the BIOS settings and HWInfo)
https://imgur.com/ORL6KXE (Bios Settings)
https://imgur.com/vOxBeS9 (HWInfo)
As you can see, even if I change the Ratios for both CCX (47x and 46x) I only get 4 cores with changed frequencies (2 with 4,7GHz, 2 with 4,6GHz, the rest running at standard 3,7 GHz). This really needs a fix in the next BIOS version. In case I'm making a mistake please someone tell me what to do differently.
Best regards,
Markus

Originally posted by g111 View PostGuys I have a question I've been wondering ever since I got this board.. is it normal for vDRAM to fluctuate this much? For example if I have my RAM voltage set to 1.35, it idle at 1.35v, but with load it will rise to 1.4v. This happens no matter the RAM voltage. Idles at x.xx, but adds .05v under load, as confirmed by HWInfo64. Is this by design? Does it happen to others?
This happened for this B550i Aorus Pro AX from day 1 across all BIOS revisions I've tried. I am now on F11, same behavior.
(I also have to compensate in the BIOS by setting a lower RAM voltage, because if I set to 1.35, it will actually be 1.4v idle and 1.45v load. This also happens in optimized defaults with voltage set to auto, with XMP profile.. RAM is supposed to be 1.35V at XMP, but will boot up with 1.4v - and of course go to 1.45v at load. So I have to undervolt to get correct voltage to RAM)Originally posted by neo387 View Post
Same here f11 1.44v results in 1.5-1.512v under heavy load (tm5-anta777) if hwinfo sensor is right? Xmp 1.35v gives 1.41v
On previous bios f11d and f11j I had this at 1.45v for same result.

So yea + 0.06v is kinda allot for ram and potentially unstable for non bdie
While all other volt settings give slightly lower..

Hilarious. So between this and the CPU volts/temp change some people experience, Gigabyte is basically risking ruining many people's entire desktops, multiple parts. How can they release a final BIOS (F11) and many beta bioses before this, and not double check correct and stable voltages being delivered to components?
This is amateur hour.

I wouldn't discount your issue, But is your Ram RGB? On the X570 Master with multiple brands the Ram, the Voltage has a bit of flux like that even at "idle", But if you use RGB & XMP (multiple brands & Die tested) set it to 1.37/1.38V instead of Auto/XMP1.35V it becomes 100% stable. If you overclock then....more work involved.
??
I target 1.5v manual settings not xmp
Bios 1.44
Idle 1.48
Load 1.51
?????
?????Cannot reduce further for the 1.5v target cause then idle might get to low and crashdoesn't X570 have another setting some sort of load line for ram? There are also other voltage settings below ram maybe those help idk

Mine is not RGB, and also tried a different (non-RGB) brand and timing, with same results

I want 1.5V constant. But what I need to do is go in bios, set 1.46V, to get 1.5V idle in Windows (also reports 1.5V in BIOS live reading under "PC health"). But then in load it is 1.545-1.55V. So my RAM OC has to be calibrated for this load voltage... but since under non-load conditions like desktop use it is 1.5V, it might be unstable with my timings. (luckily so far system is stable luckily for me), but this is crazy weird.
But it really varies by load... light desktop use: 1.5 (with 1.46V set in BIOS). Light load->1.52V. Heavy load (Prime95) ->1.55V
maybe Gigabye invented PBO/Curve Optimizer for RAM ???? but they forgot RAM doesn't have ability to adjust timings and frequency on the fly xD
