My whole system is not stable anymore and I can't seem to stabilize it. No matter how much Vcore I put in. Its still give me the 0x9c BSOD and even if I try to raise VTT, same thing. Does the VCCSA has something to do with more PCIe cards?
Have you added a heavier powersupply, or still running the 950 Enermax?
For Rex4, q-Fire and a decent OC it seems a little light to me.
