Topic Typo, didn't mean to put "Gene" in the topic. The MB is a Maximus VIII Hero".
My 6700K landed today to complete my build. Turning on the machine hangs at code 55 - Memory Not Installed. If I remove the Memory, I get the normal "Missing Memory beep" error 53. I have tried inserting the memory one stick at a time into DIMM_A2 and then tried pairs in DIMM_A2 DIMM_B2. No luck. I pressed MEM_OK, the system shut down and started back up with the yellow DRAM_LED light flashing, but it never completes.
I am using:

It's possible your cpu waterblock is too tight causing uneven pressure on the cpu and could be causing code 55. If it's not booting with one stick this could be the problem or you may have some bent cpu socket pins.
If loosening your waterblock a touch doesn't help, remove your waterblock and cpu and inspect the cpu socket for any bent or misaligned pins. Use a magnifying glass in good light, look close and carefully.
