If you're using ATi's OverDrive to clock it, you can't.

Use MSI's Afterburner & turn on 'enable unofficial overclocking' in the config, which you'll find in the Afterburner folder. That should allow you to go higher, if your card can cope with it.
 
cant us ati's overdrive in the ati's control panel as its all grayed out although it does display everything i just cant change anything.
I have installed msi overdrive and altered the config file but it wont let me go any higher than 960 ?
 
managed it was not saving the config file right so copied it t documents and edited it and the copied it back to the msioverdrive folder again.

thanks all for the help :)
 
wanting to try and overclock it to 1000/1500 but think i need better cooling as no matter what i set the vcore voltage to it starts crashing and locking up
 
The stock memory is what, 1200? And you're trying to push it to 1500?

Even with extreme cooling, that's a lot to ask for. Start low, work upwards.
 
You have to be careful when overclocking 5 series ram, a lot of the time the highest frequency will actually be slower than lower ones as the ram uses ECC and will use an algorythm to correct errors making it seem stable but it will actually be slower. The only way to overclock the ram and make sure this is not happening is to clock the ram a bit and test, repeat until you notice a drop in fps in your testing and thats the maximum you should use, anything higher willl be slower.
 
yea have droped the ram back to 1445 as 3dmark 06 was lossing 1500 3dmarks with ram clocked too high so have settled on the max overclock in the ati control panel of 960/1445
