Must agree with Silent scone
The vga port on 290x are happy when putting 1.43v+ true core. Only when use dp port i got prob when going over 1.42+ core.
Doesnt matter of clocks of core.
it lost signal when was on stock clocks but with 1.43volt on core
So 1000/1250 with 1.43v core no go on dp port on my 290x no heat prob.
with vga port and 1.43+ i am heat constrained but can bench with 1340/1700....![]()
I just tried 1.412v on my cards with no OC and tried to run Firestrike @4K, no good I lost the signal as well.
I think you would be wasting your money on different cables though as I have quite a few and they all lose the signal.
