Dude I'm quite new to the PC world. I do have some occasional freezing when I watch youtube on chrome but if I refresh the tab it starts working fine. Or even if I wait for a few seconds it returns back to normal. I haven't noticed any other issue other than that so far. I have run memtest86 and there were no errors. And I also ran prime95 for an hour in the blend setting with no errors found and I only had built the PC just a month ago, all new parts. I had the XMP enabled at 3200MHz auto all these time. So it that freezing an instability?
Also, this is mentioned in my motherboard ram support list.
" AMD Ryzen series CPUs (Picasso) support DDR4 2933 / 2667 / 2400 / 2133 non-ECC, un-buffered memory* "
My processor is a Picasso one as far as I know(Previously mentioned that the cpu memory support is 2933). Again at the end of the motherboard ram support list, it says that it supports XMP memory modules. So under that case can I enable XMP? And when I enabled XMP from the bios few days ago, it automatically set the advertised speed of my ram module. And the only issue that I have faced so far it that youtube thing that I mentioned. And even then, that only happens maybe once or twice a day as far as I have noticed.
Here is the link to the motherboard specifications from the official website
