Well post back, If anyone has had the same problems as me with voltage not setting correctly for low volt ram like the ocz blade which needs 1.8v - 1.9v to work I have written gigabyte about 5 times, the last time telling them basically that the 790x-ud4p could go from being a very good product to an excellent product with a little refinement and they needed to open up some more memory options for better fine tuning. I described to them that how out of 5 sets of memory I have tried in this board, only 2 would do advertised timings and speed with voltage advertised, 2 would'nt work (would error out in memtest instantly) anywhere near advertised speed (1066) no matter the timings, and 1 was overvolted. They said they would forward my email to the bios engineering department for consideration hopefully that means they will look into things. I am not a world famous overclocker just someone trying to get more for my money but I explained that a even though the 790x was not the ultra high end, that alot of enthusiasts were buying this as a cost effective solution for gaming, and that enthusiasts like options to tweak, that the 790x although inexpensive compared to its brothers the 790gx and 790fx, was more of a gamers board due to lack of integrated graphics, and its bios should be treated as such, not neutered.
Hopefully they are listening.
