I bought 2 reference powercolour BF4 editions yesterday on the day only deal, I'm intending on mining with them whenever I'm not gaming (no time anymore anyway 
).
I got black screens within 10 minutes, I must have had about 5-7 in an hour easily. This is with one card installed, so I tried the other and the same again. Tried them both, and swapped them round and still the same black screen issue... I've ordered a better PSU (AX200i coming tomorrow) to replace my XFX 850w but even with two cards on Valley it got halfway through and then the screen signal was cut, the psu didn't turn off. They occur even if I let the computer idle.
Also the memory is Elpida, kinda sucks for the miners. I read the MSI gaming edition comes with Hynix memory modules, can anyone with this card please check and let me know what you have? Also is the board a reference board (for waterblocks). I think I intend on sending these back and getting the MSI gaming edition for the Hynix memory.
