R9 270x Overclocking

[Dreditz]

So I'm running an Asus R9 270x DC2T in my rig and I haven't been able to achieve a stable OC. My benchmarking game is BF3.

 

I'm curious if anyone else has discovered a stable OC with this card.

 

The image below is just for info and obviously not my OC.

You should just one clock one setting at a time and do it in small increments.

Yep, add 10-20mhz and apply, test,..if its stable, repeat, if you cant do one step.. its a DuD OC'r.

If it works at stock clocks, it is within its bounds, if it is unstable at stock clocks, RMA it.

Start with the GPU clock, and go by 10-20 MHz. If it becomes unstable, add about 5 mV of voltage and move on.

Download MSI Afterburner or Asus GPUTweak and If your card has unlocked voltage control push the voltage as high as it would go, then benchmark and watch for temperatures, if the temperatures don't exceed 80c then you're fine.
If your card is voltage locked you'll end up having to do a lot of googling to figure out how to unlock it, chances are you'll find a lot of folks with the same card on OCN who have managed to unlock it.
Now start pushing the clock speeds, raise the clock speed to by 20mhz increments and benchmark for stability, go for 1140mhz, then 1160mhz and so on, until you start seeing artifacts, once that happens reverse back to the highest stable clock speed you've tested.
