R4E - All slots running at 1/2 speed

MMFC378
Level 7
Need a little help guys.

All my slots are running at half speed. x16 only runs at x8 and x8 runs at x4. Ive moved my 1080 to every slot and its the same result. Forcing Gen 3 also cripples my system for some reason. Major stuttering in windows 10. So i only get Gen 2 x8. Its set to Gen 3 in the bios and I flipped the dipswitch for every slot i used and same result.

3930k
RIVE Bios 4901
16GB G Skill 17000 CL11
GTX 1080 FE
EVGA 1000W

I removed the CPU and checked the pins, everything looks good. CPU contacts looked clean as well. It also hates restarting from the bios. It hangs on random debug codes like 16, 0C, 62,64,92,67. It seems to hang just before it would initialize the gpu.

62- Installation of the PCH Runtime Services
64- CPU DXE initialization is started
92- PCI Bus initialization is started <---seems to be a big one, but this one doesnt show every time
94- PCI Bus Enumeration

Again, these are just a few of the numbers i remember and only seem to occur when it restarts from the bios.

Heres a little from cpuid
