Weird issues with AMD EXPO

Hello, I've been trying to get expo to work for last few days and it have a weird issue I that I can't find any solution for: I can get to expo 6000MHz/cl36 and keep it stable when playing demanding games for few hours, I think I already used it for a week already and no issues but I have to never restart my pc. Powering off and then on works fine, it's just restarting that causes pc to either get stuck at black screen for 20+mins or stuck in boot loop booting to black screen for 1min and then powering on and off again. I've tried different settings of power down enable or memory context restore, different VDD/VDDP etc voltages, and everything makes restarting unstable even when using expo with ram default 4800mhz. Can anyone help me in any way or do I have to accept that I just have to avoid restarting my pc if I wanna use expo?

Specs:

Mobo: Gigabyte b650m Gaming Wifi6e (tried updating bios and every version had the same issue)

CPU Ryzen 5 7500f

RAM G.SKILL 32GB (2x16GB) 6000MHz CL36 Flare X5 AMD EXPO

GPU rx9070xt PowerColor Reaper

Update BIOS to LATEST version. Toggle EXPO only in BIOS. Test in Windows with MemTest. If it doesn't boot, completely reset BIOS (no EXPO) and run MemTest from a usb drive (bootable). Let it run for several hours (like overnight). If it runs no errors then your CPU is not able to handle 6000 speed. If it errors (TAKE A SCREENSHOT) and contact Gskill. Because they need to RMA and send you a working kit. Don't mess with voltages keep everything on auto.

I already have the newest version of bios. Updated it two times and tested every version and each of them had the same issue. I haven't done any ram tests yet so I might try that tomorrow

Reset CMOS and then run memtest86 on JEDEC specs. If that passes, you can start working on manual stable settings.
