Possible update needed for ZOTAC Magnus One

[mikeymouse2024]

Hello, guys! I have a Zotac MAGNUS ONE ECM73070C with the latest BIOS. I read many topics that said 11th CPU gen isn't supported. So i replaced a 10700 to 10900F CPU which is supported. The system started and working fine except one thing - the PC doesn't wake up from sleep properly. It reacts on mouse and keyboard, however the display stays black and even wifi and hdd leds don't function. Only power led goes green and nothing happens. I have to manually hold power button to turn it off. With 10700 CPU there wasn't such a problem. I found some weird option C6DRAM appeared in BIOS (which didn't show up with 10700 CPU), i tried both disabled and enabled.. it doesn't change anything. 

Please help me with this issue, i'm sure probably there's some problem in BIOS? If you need any additional information i will gladly provide it. I don't want to downgrade to 10700 again...

P.S. the issue might be with some C6 state incompatibility, probably they're different with those CPUs... i have no clue honestly but this new option in BIOS worried me.

Do Load Defaults in BIOS, save and reboot.

Thank you a lot for your response! I have reset all BIOS settings to default values, loaded Windows and here what it shows under this node:

Nothing unusual. Only shows the only adapter I have. On my old CPU 10700 with default it would also enable IGPU.

Also i checked, disabling C-states in BIOS doesn't change anything... still no proper wake up.

OK

Sure! Here's a screenshot of this section.

I think that's not BIOS problem.

I think that's not BIOS problem.

But it started right after i switched CPU to 10900F. I'm sorry I'm not a BIOS specialist. Does it mean that there's basically no any specific option or code in BIOS that might affect different sleep behavior depending on CPUs?
