XMP lowering clock speed+perfomance on Ryzen 7700X

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey guys,

So I am running my CPU with my Asrock B650i Lightning WiFi mobo and I wanted to enable XMP on my RAM kit (Kingston 64GB KF560C30BBK2-64 at 6000 MT/s, CL30-36-36)

After enabling this setting, my PC is in fact running slower than with standard JEDEC speeds (slower on boot time, lower clock speeds and overall lower performance in a benchmark like Cinebench R24). My Bios is updated to the latest version (3.20) and I am currently running my CPU at -20CO offset via the builtin profile in bios. Also in Cinebench I noticed a decrease from 860 to around 690ish points with XMP enabled.

Is this a motherboard limitation? (with it being a mini ITX, maybe there were power constraints with the VRMs?)
Or could it stem from a thermals issue?(I am running quite hot on the CPU in this SFF build, reaching TJMax of 85c from the built-in PBO profile and sitting normally in high 60s-low 70s)

Thanks!
