I had my Max V in a TJ08-E with a CM V8 and decided I wanted to go back to a closed loop water cooler, and bought a CM Seidon 240M. I took my build apart in the TJ08-E and put it into a CM HAF XB, and also installed a Centrino 6235 mini PCI-E wifi card.
When I made the switch I did not remove the CPU or RAM. I also used the same HDD's and did not reinstall windows or do anything else, the video card went back into the same slot as before. Upon startup I was getting a 55 code on the motherboard, so I searched on the forum and found someone else had this problem on a new build. He finally got it to boot by removing all but the outer stick of RAM. I did the same thing, got it to boot. I assumed maybe it had to do with overclocking issues so I reset the settings to default, cleared CMOS, then reinstalled the RAM. Code 55 again, I tried with two sticks in the two outermost slots and I got a good boot there as well.

I tried swapping memory from my workstation (4x8GB G.Skill Ares 1600MHz) and got the exact same code. I had absolutely no problems before the swap, and the lights on the Crucial memory come on when I boot the PC and show blue (they're blue and orange) which is normal and dont seem to indicate a problem.
Any suggestions? It's attached to a motherboard tray, some have suggested maybe the board could get warped but I would think that would cause it not to boot at all. I loosened the screws just a tad in case that was the issue.
