Question PC restarts multiple times if I set RAM to XMP then resets back to non XMP

[t1redmonkey]

So I recently bought some new RAM. It's Corsair Vengeance RGB RT 32GB (2x16GB) DDR4 4600MHz C18 Desktop Memory.

After going into BIOS and changing the memory profile to the XMP one, my PC restarted about 3 times, then went to a black screen for about 5 seconds, and then Windows loaded. However when I checked my memory settings after this, they had been reset to non-XMP.

I don't really get why the RAM isn't working at XMP, since my motherboard does support up to 4733 OC memory.

My motherboard is B550 AORUS ELITE AX V2 (rev. 1.3) and I do have the latest BIOS version.

Any idea what could be going wrong?

What processor have you paired with that motherboard?

5800x3d - just installed today.

RAM in slots A2 and B2 as well. Previously was using 3200mhz CL16 RAM at XMP with no issues.

It is supported but anything that says OC at the end is not guaranteed.

Set XMP then manually change the speed to 4000.

Thanks! Well I changed it to 4400 first, and it worked so I'll see how it goes.

I would run memtest to make sure it's stable.
