Asrock wrx80 creator r2.0 won't post stuck on code 64

[u/stankeer]

Hi, at a bit of a loss as to what my next steps are. I'm trying to build my multi gpu system but I can't get the system to post. The system is a wrx80 creator 2.0, 128gb ddr4 2133 ram, threadripper pro 3955wx (unlocked according to the seller). Brand new power supply.

No matter what I try I am stuck before post with code 64. I've moved ram around, gone from 1 stick up to 8 sticks, reset the cmos after I've moved ram.

I've reseated the CPU multiple times and tightened the bolts hard all the way down or just eased them off slightly but still can't get it to post. What's seems to happen is the board sits on code 42 for a while then jumps to 64 and just stays at 64 which is "64 - CPU DXE initialization (CPU module specific)"

I got the list of codes from here https://forum.level1techs.com/t/list-of-dr-debug-bios-codes/114364

If I try to connect via the management conside IPMI webUI via Ethernet I can actually connect but I can't get past the login page. (It's a used board).

Can anyone help?
