Success! 12.0.1 Monterey on GA-B75M-D3H (Haswell E3-1240 v2)

. .
CPU Intel Xeon E2-1240 v2
Motherboard Gigabyte GA-B75M-D3H v1.1
GPU Sapphire Pulse Radeon RX 580
OpenCore 0.7.4
SMBIOS MacPro6,1
Ethernet Onboard RealTek RTL8111

Everything seems to be working. Sleep/Wake, Wake on LAN, DRM, iMessage, etc

Upgraded from OC 0.7.1, all I had to do was fix the issues identified by ocvalidate and the same config from Big Sur worked just fine. No substantial changes to the content were required.

I did a fresh install because I borked my username when I installed Big Sur. The only trouble I had with that process was that the standard method for building the USB resulted in a failure during the install claiming that my USB was corrupted/damaged. I rebuilt using Method 2 of the Linux instructions and that seemed to be fine. I had to do the same when I did the fresh install of Big Sur a couple months ago, too.
