Code 55 on Maximus VIII Formula

[alexander.o]

First, my MoBo gave me a code 55.

Then, I fixed it by waiting a day and then reseating the RAM.

Now, after delidding my CPU, the MoBo is giving me a code 55. 

 

RAM works. 

CPU contact pads/MoBo CPU pins are clean. 

BIOS is the most recent (v 3801).

I have tried switching around the RAM modules, nothing works. 

I have tried resetting the CMOS. 

 

Any ideas?

 

System specs are:

6700K (delidded w/ Conductonaut)

32 GB DDR4 (SKU: CMK32GX4M2A2666C16, on the MoBo's QVL list).

WD BLUE SN550 1TB NVMe

RM550x

EVGA GTX 1070 SC
