My new MSI 7970 has come. Check this out

1125/1575 STOCK VOLTS!

Vs my Windfarce gigabyte card which topped out at 1050/1400!

Now need a better program to clock past afterburner limits.
Add the option "-xcl" (for extend clock limits) to your Afterburner shortcut's target, run it once, reboot, remove the option and run Afterburner like normal. It'll give you much more range in your sliders now.

Holy memory clock batman!

1125/1850 !

Core seems to like 1125mhz at 1174mv and will run Heaven on 8xAA max everything at 1850 and crashes at 1900mz!!

im going to settle on 1125/1800, this has zero artifacts in heaven.

Glad you found it. Running the memory at 1800MHz is a good choice because memory instability can reduce performance due to the card's ECC long before it shows up in game or crashes it. Happy gaming! :thumbsup:

Yeh its surprising since i couldnt get past 1400mhz on the other 7970.

Its a shame my GPU wont go above 1125mhz without the white flickers in the shadows appearing. voltage doesnt help either.

Cant grumble for the money though

I'm surprised extra voltage doesn't help the core. How are your VRM temps? How about the core temp? How high have you pushed the voltage?

Not sure on VRM temps.

1125mhz is perfect at 1174mv Max temps 78c on benchmarks

I have tried to push the volts to 1250mv and the white flickering in the shadows still appears.

GPU-Z will give you the ASIC score and should show you the VRM temps.
