14900K Linux AVX2 Issue

[Rishib]

Hello Community,

Got a bit of a head-scratcher with my setup. I have two SSDs configured for testing purposes: one with Windows 10 and the other with Rhel 8.9. When attempting to set AVX2 to auto or enable and running Prime95 on Windows 10, it downclocks by an offset of 4. However, when I run Mprime (the Linux OS version of Prime95), it doesn't downclock and instead throws a segment core dump error, resulting in test failure. I've even tried resetting the BIOS to optimize default settings, but no luck.

Any ideas what might be causing this hiccup?

CPU- i9-14900K

Mobo- ROG MAXIMUS Z790 HERO (BIOS Version- 2202)

RAM- Gskill 5200MHz DDR5
