Thanks in advance.

Not a reference pcb ( blue one ), i will not take the risk for 50mhz more .

You can reach the 50mhz gain, even without overvolting by the CCC...

Does anyone know if this card has been known to take the ghz bios? http://www.tigerdirect.com/applicati...&Sku=P450-7976 Im thinking about cf. The card i have now has the ghz bios in the second bank would be nice to have both at 1050 / 1500 and hopefully lower voltage if im lucky enough to get another high asic chip.

Doesn't look like it will. There is a couple of people here warning of the voltage lock on this card: Brian (about midway) and one 4 below him.

Plus it appears it doesn't have a bios switch option.

Sorry to bring up an old thread, but it is a stickie

I'm running with two XFX R7970 and the temptation has come to flash them to a GHz ED.
I can easily run them at 1125/1500 with stock bios in CCC, but when it's free to flash i have to give it a try.
So have anyone else flashed a XFX 7970 and is it safe? I don't have the biod switch so there is a chance for "brick"

Or should i just run it as it is?

You could use Afterburner to overclock instead of flashing.

I flashed both my Sapphire 3gb refrence cards and they OC pretty well now. Stock firmware, I was not able to change the Core clocks with a system crash. Pre-flash, i could change the core + - 10-15mhz and would start to artifact, after i flashed i am now running 1150/1825 stable through MSI after burner. I dont use Trixx because there is a bug where the software will not control the GPU 2 fan with GPU 1.

My OC gave me an additional 12-15 avg fps on Tomb Raider benchmark and my temp stay under 70c with my fan settings.

So is this "guide" still up to date or is there newer and more secure ways? And which bios should i choose?

I then restored the original and reflashed a couple different GHz ed I found around the net and all gave the same result.

For anyone who comes across this problem you can easily flash your original back by flipping the switch on your card to "1" restart windows (this loads your second bios which has the original) run ATIwinflash and "save" your image/bios. Then flip the switch to "2" while in Windows, run ATIwinflash again but this time load and flash your backup.

So randomly decided to give it a shot again today, worked flawlessly first try. 13.3 Beta 3, Diamond 7970
