Does anyone have a working configuration for the DELL 9020m?
Have you tried going through the OC guide by Dortania yet ? What from this guide have you tried so far ?
Note that the CFG unlock method does not work for the M (micro) motherboard. That's why I'm keeping
this thread focused on just the USFF, SFF and MT models for consistency and to prevent confusion in readers.

For your Micro version you'll want to try AppleALC layout-id of 27 and SMBIOS iMac 14,4

As far as someone posting a completed EFI folder, I don't encourage that as it prevents
people from learning the important things they must know to be a hackintosh owner.
Other than that it generally doesn't work well as everyone has different requirements
for their specific usage scenario.

It's probably best to follow the general guidelines of this thread:

Of course you'll need to generate an OC EFI folder. Use the app by Pavo that I've linked to in my guide.

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.

Hi, thank you for the awesome guide. I am having one small issue. I can't seem to get 60hz in any resolution higher than 2560 x 1440 (connected DisplayPort to mDP). Normally, I'd be fine with that, but it is not HiDPI so its fairly fuzzy. This is with the iGPU. I also have a dGPU (Nvidia GT 710) that seems to be having the same issue (connected DVI to HDMI). I have a 4k panel, so I am considering patching my DVMT, but I'm kind of nervous. Any thoughts on what could be going on?

The GT 710 has HDMI 1.4 not 2.0 so it can't give you 4K/60Hz. DVI will never even give you a 4K resolution. Your HD4600 will only give you 4K/60Hz when DVMT is increased to 64MB. Follow the guide to change the offset so you have 64MB available.

Which Dell Optiplex do you have ? Is it 7020 or 9020 ? SFF or MT ? It should be in your hardware profile.

Thanks for the quick reply! Updated my profile to reflect what I have. Sorry about that.

As far as knowing what my DVMT is currently set at, is there a way I can see any of that information somewhere? I know its hidden in the BIOS but I wasn't sure if there was a way I could check before getting into changing it.
