A little update; I've brought home a Sabertooth, an AMD FX-8120 (the Phenom got killed when it tried to take it out of the Crosshair), a CM Hyper 212 Evo and a Corsair AX650 V2 and it's still sort of the same.. The DRAM_LED is lit up and MemOK! doesn't seem to solve anything.. I've tried both the HyperX and the Vengeance in it with the same results.. None of the sticks are on the QVL for the Sabertooth, though, but I'm just sick of buying stuff just to find out that there's a new problem (I've been having issues since November 2011)
Is there really nothing else to do than to buy a new set of RAM sticks (from the QVL)?
