I have some years of experience in overclocking various processing units, however, I'm at a bit of a wall with this one, so I'm looking to get some fresh minds looking at it. I'm looking to overclock my GPU, and just for reference, I've extensively looked at the accomplishments others have made with the same card. They vary a bit of course, based on PSU/cooling/etc, but from what I can tell, even with the stock double dissipation, one should easily be able to achieve 1100MHz+ with this card. Here are the specs for my card(you'll have trouble finding it in google, because apparently my version of this card is rare. Mostly you'll only ever find the 4GB XFX version, whose memory clock is 1250MHz, whereas mine is not):
Base core clock: 1000MHz
Memory clock: 1375MHz
8GB GDDR5
Dual 85mm fans(double dissipation)
I've been able to increase the clock speed to 1070 with stability, but anything further than that causes the driver to crash. I noted something in the settings though: The stock voltage is set at 1225mV, which, to me, seems very high for a 1000MHz base clock. I've lowered it here and there, though it does little to remedy the problem.
I recently rebuilt this GPU, installing new fans and reapplying thermal grease. The XFX versions of this card are designed to run at 95C at full load. After the rebuild, the average temperatures reduced 10+ degrees. The only thing that brings it to full temperature now is VR. That said, I believe the rebuild improved the cooling system sufficiently to easily accommodate an 1100MHz OC. Anyone have any ideas as to why it's not working? I've lowered the voltage in 10mV increments all the way down to 1075mV, and I've increased the power limit to full. I'm not sure what the issue is.
