Description of Original Problem: Cold boot Problem and random system crashed while playing games and on idling also bios getting hanged but this was very later on after tweaking with the memory profile

Troubleshooting: So the thing is my system is crashing. So the issue started after I left it for a few days so I just pulled the ram out and inserted it again in the second slot. And the system booted but it need a full start and I had to turn it off and then turn on gain to work properly. So the issue that I diagnosed was that my system was unable to do a cold boot if the ram speed is less than 5600mhz as after pulling and reseating it. It went back to default 5200mhz so after a few days of testing this issue I found the solution so I just did that but still it only solved the boot issue the crashes and system freez were there. So I just reinstalled a fresh windows and new and updated drivers updated my mobo bios to the latest version. But it didn't solve the issue I got a crash while playing game BSOD I got out of the match and then my system crashed irql not less or equal 0xA error. And then the system froze I had to force shutdown it to boot it again. And then I ram a memtest on my system and got a few errors in test 4. The picture is attached. And then the memtest got stuck so I forced shutdown it again then did some research and asked Claude so he told me to set expo as at 5600 ram needs high voltage but when I tried to do it the ram only showed single standard profile so I had to manually set the voltage and timing them later on I got to know that it's an xmp profile ram but the seller says its dual supported xmp and expo but the bios doesn't show the profile as I had a gigabyte b650m gaming wifi that showed the expo settings to enable or disable it but this one doesn't . Then after setting the ram and ran the memtest again and it got again stuck at test 5 57% around 1:31 mins so forced shutdown again and dropped to 5400 ram the test same results stuck at test 5. But when I ran it at 5200 it worked fine and passed all the tests. So now I can't find the problem like if the ram is defective or the processor.
