x670e Extreme + 7950x3D + Rtx4090, gpu problem at @6000mhz

Crashksk
Level 7

Hello,

I have x670e Extreme motherboard, 7950x3d processor, G.skill 6000mhz (F5-6000J3038F16GX2-TZ5NR) ram and rtx4090 suprim x graphics card.

Sometimes, If I set my ram to expo1 or expo 2 profile (@6000mhz cl30), the system does not fully recognize the video card at boot and I get very poor performance. Also, When I checked with Gpu-Z, it show as PCIe 3.0 (only when it problems).  But if I overlock the rams to 6200 mhz or 6400 mhz with standard settings, it opens without problems. 

What do you think is causing this problem?

I am using windows 11 and bios 1101 is installed.

Thanks,
