That was the fix! Thank you!Looks like you've still got the alcid=1 boot flag active so remove that and your audio and it should then work.

Sounds like your CMOS battery is not retaining the settings. Did you replace the old one with a fresh battery ?iam having problem with bios is automatically changing to raid and offset code also changing to default.
No I didn't replace.Sounds like your CMOS battery is not retaining the settings. Did you replace the old one with a fresh battery ?
Have you tried going through the OC guide by Dortania yet ? What from this guide have you tried so far ?Does anyone have a working configuration for the DELL 9020m?
First you'll need to add your Dell hardware to your signature or your main hardware profile. Your choice. Include the CPU and graphics you have. For motherboard, simply put in Dell 9020 USFF.H I have a problem with my Optiplex 9020 usff only the USB 2.0 ports in the back work. If I activate USB 3.0 in the BIOS then MacOS doesn’t start up anymore
