Question OC RAM from 4800 to 5600 - Get instability

[CptNeckBeard]

I see others stating they have OC'd their RAM past 4800 with the i5-12600K but on Intel's site it says that the i5-12600K only supports Up to DDR5 4800 MT/s. When I use XMP on my CORSAIR VENGEANCE DDR5 RAM 64GB (2x32GB) 5600MHz CL40 I get instability and BSODs. MemTest confirmed the RAM is good. AIDA64 stability test is fine with XMP off. Am I limited by my CPU?

That is the first generation DDR5 CPU and those are very large memory chips. You can try increasing the DRAM voltage slightly to see if that helps.

I'll give this a shot, ty

Proper bios?
