OCing the HD7950 XFX Core Edition

[Temporeiches]

Hello,

I would like to ask you what Core Voltage, Core Clock and Memory Clock you use to overclock this graphic card (im using the stock fan). At the moment I tried several settings using MSI Afterburner, but I did not really find a stable solution.

Thank you in advance.

Start off at stock speeds and stock voltages, increase core clock by 10mhz at a time and stress test to see if it's stable.
If you see artifacts or if the GPU drivers stops responding, increase the voltage by .01 or .02 volts.
When you're finished and you don't want the GPU to run hotter, increase memory clock by 50 mhz at a time until it's unstable.
That's when you back off 50mhz on the memory clock and 10mhz on the core clock and keep it there.
