ASRock Rack EP2C602 Install Guide for Sierra and High Sierra

Yep it's a PCIe add-on. Here is what I did in Ubuntu, and the IORegistryExplorer (if it's the right place to look!)

The good news is it doesn't appear that your flashed the PCIe WiFi adapter. However, I don't believe that adapter is supported out of the box in macOS. I may be wrong (I only use wireless on mobile devices and hardwire all desktops, so I am not very knowledgable about WiFi support). Have you taken any steps (not covered in this guide) to enable functionality?

Thanks a lot, the first method worked! Now I'm just stuck with this annoying GPU issue, almost there!

EDIT : Also, I got really poor CPU results, and I figured that one is missing… Whereas my OpenCL benchmark is quite good

EDIT 2 : I figured it out too, got my processor back! Better results but still not optimal

BIOS Guide attached to original post. Use HWSensors to confirm that CPU PM is working, specifically turbo states.

Thanks a lot! I get slightly better results, but not significantly. Here is my HWSensors tab, not sure of how it should behave

Also, I was wondering about your SATAIII Hot Plug setting; is it the same setting for every entry? Or just the empty ones?

I found that I must set it for any optical device. I set it for all drives, but it isn't completely mandatory. I was trying to keep closest to a real Mac configuration since clearly no existing Apple product supports hot swapping.

Alright, it gives me the forbidden sign so I'll keep it on for now! And for the graphics I'll use the one that works for the two displays for now too.

I'm still not at your level in the benchmarks though, I miss around 1000 for single and 14000 for multicore, I don't know where they are! I also lost my ethernet again, have absolutely no idea why, will check that but at least it's stable

The E5-2670 is 8 cores at 2.6ghz while the E5-2680 v2 is 10 cores at 2.8ghz. Differences are expected, but not that large. You can use HWSensors to watch if the turbo states are engaging and if the chip uses low power states when idle.

Oh yes of course, but it can do better. What do you mean by turbo states and low power states? Sorry I'm still nooby on some parts here…

Your processor is advertised as 2.6ghz, but that’s not really accurate. Assuming adequate cooling to avoid thermal throttling, it actually runs at:

3300 MHz (1 or 2 cores)
3200 MHz (3 or 4 cores)
3100 MHz (5 or 6 cores)
3000 MHz (7 or 8 cores)

Those are the turbo frequencies. In addition, it can run slower then 2.6ghz when there is little or no load. However, that all requires a properly functioning CPU Power Management in macOS. If HWSensor doesn’t show CPU core frequencies above 2.6ghz when running various tests, like Geekbench, then CPU PM isn’t working.
