Hello, I have a problem detected by Windows 11 on the RAM, so I test with MemTest86 to see if there is a RAM problem, I test them one by one (4x32Go) of Corsair, but although I did not activate DOCP in the bios, it tells me XMP is a problem? How many passes do you need on average? what would be the optimal settings for MemTest86? Thank you very much for your advice!!link dropbox

If you have a problem stick, it will show up very quickly.
Even just one error is a problem indicator.

What you want to test is the full 4 stick complement of ram.
A full pass with zero errors would normally be good enough.

If you suspect a problem, let the test run overnight.

Are all of your ram sticks from the same matched kit?
If not, there might be your problem.

Testing one stick at a time is only useful to find one or more sticks that can let you run until you can get a rma replacement.
Quality ram will have a lifetime warranty.
The whole kit would need to be replaced, not just the defective stick.

Thank you for your answer, in fact it is a kit of 4*32Go from Corsair. When I did a test of 128GB I had 4 errors, in the first pass, then after more error, so now I test one ram at a time in the A2 socket (first right). On the Corsair site, they request a MemTest86 test for the warranty of the entire kit. I don’t understand why I have to test one barrette at a time? Is MemTest doing a test on all the "clusters" or address it sees? or is it random? Thanks again! (I put the bios in auto but it decided to install the ram in xmp, is that a problem?)

Corsair is going to replace all 4 sticks with another tested 4 stick kit.
That is why they want a test of the entire kit.
Do whatever they ask.

Ryzen is very tightly tied to ram.
Is your kit on the motherboard qvl list?
Or, is it explicitly supported by Corsair?

Is your motherboard bios current?
Many bios updates address ram stability issues.

You will need xmp(the ryzen equivalent) setting to run at 3600.
XMP is a list of settings embedded in the ram that will let the ram run at advertised speeds.
Such speed is technically overclocked.
You could try setting up the ram settings yourself for your desired speed.
Then, try increasing the ram voltage a bit.
This will sometimes fix the problem

Ultimately be guided by what the Corsair ram guys ask.

Thanks for your help and advice, I found errors on a RAM, and I wanted to test it with windows and since 2h it is blocked at 21%, and indicates that there are hardware problems, I will leave it another 2h. Otherwise to be sure not to overclock at 3600MHz I have no choice but to manually enter all the settings, and there I am stuck. In the bios I have: D.O.C.P. AUTO or Manuel. and one more question, how much I could increase the voltage for the RAM? Thank you in advance!!

Ram faster than 2666 is better binned chips that will need to be overclocked to reach advertised speeds.
3600 speed is normally 1.35v.
Higher speeds may even need a voltage of as much as 1.45v.
My suggestion is to go slow and try 1.36v. or small increments as a fix.
But, even if this works, you may still have defective ram.

My understanding is that memtest cycles through all the addressable ram using different patterns of access.

If you are overclocking your processor, either explicitly or by picking a bios option such as load optimized settings then there will be more interaction with ram.

I think consultation with the corsair ram guys will give you the best advice.
