Posted January 23 What are the causes of some RAM sticks (dual RAM) not supporting XMP profile out of the box? What would be the reason, RAM sticks itself or the Motherboard, Processor? In my B450m S2H mobo, I was using 2400mhz RAM which supports XMP without any issues, but now 3200Mhz RAM doesn't support XMP. When I enable it, sometimes the PC takes a restart. At first I thick that would be the cause of any problem in my GPU, but when I started to dig for the issues, the pointer headed towards the RAM, as when I disabled XMP, the problem was gone. Now wondering how can I use my RAM in 3200Mhz, as now running in 2666Mhz. Who is the culprit, bad RAM sticks, 4 yrs old mobo or the 3600x ryzen Processor?

Now, after reading your writing, I am thinking, can it be possible that the BIOS update made the mess? Link to comment Share on other sites More sharing options...

Newer isn't always better with BIOS updates, and it's not unheard of for different BIOS updates to break something. It's pretty strange for 3200MT/s to not work, but it is possible.
