No, stability is the same. But you can use lower voltages for the SA and IO voltage.

I would do the following.

1) Disable XMP, reboot, and note the SA and IO voltages in the BIOS. They're here:



In the pic above, you can already see elevated SA and IO voltages. With disabled XMP and after a reboot, they will be lower. Usually they are 1.050V for SA and 0.950V for IO. Write them down.

2) Set "DRAM frequency" to 3200 MHz (assuming that's the XMP speed, i.e. what's written on the packaging and modules). Then it will usually apply the other XMP settings, like setting DRAM Voltage to 1.35V and the timings. Reboot and look at the voltages again.

3) DRAM Voltage should be around 1.35V. Check SA and IO voltages. If they're much higher than the values you wrote down before, set the values you wrote down, with only +0.01V on top, so SA 1.060V and IO 0.960V.

4) Now it should still run like a charm, without elevated SA and IO voltages. You can do some RAM stress-testing now, with Memtest and MemtestHelper: https://forum-en.msi.com/index.php?...r-stress-testing-in-2020.342196/#post-1997709

Thanks my friend, I did get this replay from Intel now regarding the WHEA - I did contact them before I did write here in the forum.

"
The WHEA error seems to be an indication that a parity error was detected, likely in data arriving from memory. It could be in the processor cores, processor uncore or in graphics subsystem. This was a single-bit error, which is recoverable (can be reconstituted). If it had been a multi-bit error, it would have been more catastrophic.

Neither of these other reports had anything to do with this WHEA error. They occurred days apart from the WHEA error.

Should you be concerned? Yes. Is it the processor's fault? Likely. If it reoccurs, I would RMA the processor.
"

Reoccurs is that if it happens again right? English is not my main speaking.
But I'm wondering also regarding: "The WHEA error seems to be an indication that a parity error was detected, likely in data arriving from memory"
Does he mean that it can be the RAM? So basically the issue can be in my RAM if I do understand him right? Or do he mean the SSD?

Reocurring means occuring again, happening again, yes.

The CPU communicates with the RAM constantly. Errors can happen within the RAM or within the CPU. If they suspect it's within the CPU, we have to take their word for it.

Ok, so they are saying that this is not a faulty RAM stick. I did tell them in the first email that I had run memtest86 for 4-passes on my RAM with no issues. So I guess that's why they are saying that it's the CPU.

So I did replace the CPU trough Advanced RMA (as I need the computer for my work due to COVID I can't go to my office so Intel sent me a new one first and then I did send the old one back).
Anyway I did replace it maybe in the middle of October. And I think it was about 14 days ago I did update the Bios to v13. After the update I have not done any heavy load until today and today I did get a WHEA error again! This is driving me crazy! So I have reverted back to bios v12 and I'm hoping that the WHEA error is because of the new BIOS version v13 but I'm not hopeful.

As I have replaced almost everything at the same time as the new CPU did arrive I only have the Motherboard and PSU left from the old stuff. I have replaced RAM, Grafikcard etc. Only thing left is Motherboard and PSU.
I'm thinking it's maybe the Motherboard or the PSU but my guess is the motherboard right? I can't see why the PSU should cause this kind of issues.

The PSU is much less hassle to replace, so i would do that. Always try the easier and less expensive method first, maybe that's already it. Even if you can't see why it should be, but sometimes there are weird problems nobody can predict.

I did replace the motherboard with a Asus one. I'll RMA this board if the Asus board works better. After some googling people seem to have issues if they don't overclock manually as I did understand it.
I'm hoping this was the right decision. And I'll just sell the MSI bord or the Asus one after the RMA. I know that I'll loose some money but I can't be without a computer as I'm working from home and after two days without working then I'll loose more money then the boards cost so.

hi again,
I have replaced everything in my computer I did go from MSI motherboard to Asus everything has been replaced beside my 3 nvme Samsung 970 plus 1tb disks.
But I still get WHEA errors I’m totally confused.
It’s possible but not likely that intel have sent me a broken cpu I guess.
This issue are driving me nuts!

is it maybe something in the microcode in the bios as I have the same issue with two different motherboard venders?
