I've had a bit of catching up to do, along with a very steep learning curve regarding clover.

I recently built a new machine with a Gigabyte H270-HD3 and a i7 7700K.
This runs well but still needs some optimization.

The thing that surprised me the most is that my old hardware seems to run 10.13.3 on really old graphics cards, using clover.

Even an ASUS 8400GS which didn't even run on 10.8 using Chimera, is running at fine on clover with NVIDIA injection.

I modified my original DSDT's to fix the new USB architecture.

Boards I've got running so far are:

P55M-UD2
P55M-UD4
P55-UD5

Everything is working spot on (even sleep on 10.12)

Please find attached modified DSDT's.

I have two boards that won't even get to the clover boot screen.
They get to "Loading Operating System.........6_" and no further.
No idea why as they still both boot the old Chimera 10.8.5 drives fine?

These two boards:
P55A-UD6 and P55A-UD3

Cheers
