This is the 2nd Rampage V board. The first was DOA when tested, and would not POST. Returned and was sent one that at least boots into BIOS. Trying x3 different external DVD R/RWs, with a W7, W8.1 and several linux distro install discs. So I've narrowed down that the media, and the external drives are not causing this. Support had me flash from BIOS 0706 to 0901, yet this still persists: On W7 install, it gets to Starting Windows and freezes (no tiles ever form), on 8.1 it begins to load, BSOD's and restarts with no error codes at all. On linux, it freezes. I began to pull everything. Cannot pull the GPU, as I have no SPDIF optical out. Tested it thoroughly at work burning in for 48hrs.I did notice it pushed through once with only one 8GB dimm of ram, but switching out and testing the others by having banks A1 and C1, it does not matter what I stick I put into C1, it will still freeze. The manual shows the succession of installing RAM as such: Red dimm slots, A1, then C1. Tried once just the two reds on he left side of the socket and the it still froze. At this point it's unlikely to me that x3 sticks of RAM could be bad, but perhaps the dimm socket C1. Found where I could set the memory in BIOS to the 2400, and also the configs for Hynix 4x 8GB, etc. Any advice would be greatly appreciated. I'm a bit at my wit's end.
