Z170X-UD5 TH Running fine with unsupported RAM, but Debug LED reads 51 or D4?

Hey guys, first post here, for my first computer build. I'd love to not have to RMA my board because it would put me out of work for a couple weeks.

Here's my situation: my computer has been running with few issues (got stuck in a automatic repair boot loop once, but that's it), but otherwise it's been smooth sailing. After I fixed my bootloop however my debug LED gives me either 51 - memory initialization error occurs, or D4 - PCI resource allocation error, out of resources. I just found out recently my memory is not on the supported modules list, could this be the cause of my debug issues?

All my PCI devices appear to be working My GPU is recognized and working, I ran the memory diagnostic, and my RAM came back without errors. Ran the CPU and disk diagnostics, and everything came back without errors. The 51 Error would mean my 1st slot isn't working, but the stick in there is working and recognized.

Should I try to upgrade my BIOS or flash my CMOS? Could these resolve my issues? Should I worry if everything seems to be running normally?

Here are my complete specs:

Z170X UD5-TH
i7 6700k
EVGA Geforce GTX 970 SC AC
G.Skill TridentZ 32 GB (2x16GB) DDR4-3000 (I'm clocking these at native speed 2133)
EVGA 750W Bronze B2
Coolermaster Hyper 212 Evo

Do yourself a favorite go back to 2133 memory. You really will not see a performance boost with 3000 memory.
