I have XFX 290 core edition with accelero xtreme iv, unlocked to 290X

temps : max gpu:60 vrm:65
GPU overclocking is fine, i can max out 1150 +75mv with afterburner.
Memory overclocking is the problem, no matter how much I overclock my memory i got black screen after 5-10 min of gameplay. memory is Elpida.
It is not psu problem i'm sure. Can this be fixed, another bios maybe, or
something else....? Even when memory is on stock 1250 sometimes i get black screen after 1h of gameplay....
