Open up a Command prompt as Admin, navigate to the folder where ATI Winflash is located (easiest to just install it to c:\ root), and type the following command:
atiwinflash -unlockrom 0
atiwinflash -f -p 0 bios.bin (bios.bin being the asus bios you first downloaded)
This should flash your card correctly. I spent a couple hours trying the different methods mentioned in this thread and finally remembered the method I used to flash my 6950. Once it is flashed, uninstall your drivers, reboot, and reinstall the drivers.
I also highly recommend that you use the Asus GPU Tweak found in this 7970 pack linked earlier.
The Asus bios is great. Helped vdroop a bit and so far I'm stable at 1390/1600@1.35V (1.28V actual) running through the Metro 2033 benchmark.

Hi, thanks for the instructions. I thought this was going to do it as i had never done the 'atiwinflash -unlockrom 0' . Unfortunately though this still did not work frown.gif

I have no idea what is going on here.

Use this BIOS. It's automatic and you dont have to do a thing, Just run it and it does it all for you.

Hi

 

I've decided to get a 7970 tomorrow, so I am trying to choose between either a reference card (and if so, which brand is best), or the Gigabyte OC version (better than the XFX Black apparently?)

 

My head is spinning from reading reviews and forums, so I really need some good advice please. I'm not too worried about cost, relatively speaking.

 

Is the reference card severely limited to it's overclocking abilities? Conversely I worry about the heat dump into the case of the non-reference designs. Water is not an option for the foreseeable future. FYI I am building a NZXT Phantom which will include the Corsair H100 exhausting at the top under the 2 x 200mm case fans, and the extra 200mmm and intake on the side. So in theory I will have good airflow.

 

And if a reference card is the way to go, then which brand has the best chips historically, bios unlockability, etc. I know they're extremely similar on paper, but reading through this forum it seems that some cards O/C better than others, and present less hassles in changing the bios. Also would the associated O/C utility software have any bearing on this? eg Trixx vs Afterburner vs CCC vs Asus etc.

 

Thanks for any help! :)

If your case has good airflow.... go for the Gigabyte OC, it has lower temps. I bet either way you go reference or not, you will be extremely satisfied.
My personal recommendation would be to go either Sapphire, Gigabyte or ASUS on the reference. Which ever is cheaper.
If i was to pick one out of the three, it would be Sapphire since the majority of owners have had very positive overclocking results on alot of different forums.

Generally speaking, it looks like the ASUS cards have an easier time overclocking due to the OC software.
Sapphire and MSI obviously have their overclocking software as well.

For the reference cards, there is no binning per se - every chip on every card is guaranteed to do 925 and all of them so far have done 1000-1050, which is what the current OC cards are coming out at. Most people are getting 1100-1200 as well.

Also, you may have issues if you replace the cooler, as seen on the XFX BEDDs. The thermal gunk AMD supplied to the manufacturers is a phase change material for use with their vapor chamber coolers. People replacing this with AS5 or other are seeing worse results. And it looks like the XFX BEDD has issues with keeping the VRMs cool for long periods of time.

Anyone got a problem with single 7970 or 7970 crossfire running starcarft II?
my computer crashed many times already right after the game is over.

Also, graphic error in game as well.
my 6950 has no such error at all.

anyone?

Dude you have to flash back to the ATI default bios before trying that..... you cant run that while on the ASUS BIOS.

Denim, sorry for being a PITA here but currently my card is running the Standard XFX 7970 Bios that came on it. I have tried to flash the asus bioses, the Tahiti_XT_C3860100_X00_BIOS_Dec20_2011 bios you posted of which none flash due tot he errors i posted earlier.

Which is the ATI Default bios?
