I don't know if he did.
High sierra. Windows works fine. I could swap the CPUs back to the 2690V2s, but I need more single core performance.
Would love to find a way for these to work.

luser01, I want to get resolve a issue. Because I want to upgrade to Xeon E5-2667 v2 @ 3.30GHz (SR19W) in future. I think SR19W is the best single core performer on LGA2011 socket and pretty good multi-core performer. I'm working on UEFI to get memory and CPU overclocking. I look around to see if anybody had resloved a issue. If not then need to look at xnu kernel source code. Maybe Apple coded some restiction.
Contact amitbapat and ask if he resolved issue or get bored and moved on. Somehow I missed amitbapat issue.

@Coool actually the 2687w v2(I believe) are .1ghz faster, but I couldn't justify the price difference when I got the 2667s. Looks like we are the only ones that are active here. I will have to branch out to other forums.

You are wrong they both turbo to same frequencies. Maybe, Xeon E5-2687W v2 is better to overclock. Anyway Xeon E5-2667 v2 is best performer on LGA2011.

Have you contacted amitbapat?
I don't think that other forums can help you. Mostly all stuff on forums is boring newbie problems. ;)

@Coool No worries Im sure its related to the e5-2660v1 2.2ghz xeons being a bottleneck, the vega runs great with the i7-7800x on evga x299 micro but cant seem to boot mac so that is a project I'll work towards lol heres the 2 uefi that AsRock Racks William sent me thru support. Hope it helps you out, enjoy! The 1.80E is the uefi they created custom for me as per request to unlock the MSR in 2017 and the 1.89M is for nvme booting.
Can you point out more about how to flash bios?

I tried downloading the attached file to usb,

but not working
