I'm trying to use 2.2.8.1 at the moment. Seems the most stable.

got no idea where to get it from :/ only can find people talking about it, cant find any versions of it atall. lol... my googling skills are failing me
Soldato
Just updated.
By the notes, it's just a small update regarding voltage with the 100% fan button pressed.
I will see if there is anything else.

The card is installed and I'm doing some gentle testing using Heaven. Card seems great but after years of using Rivatuner/Afterburner I'd echo Rossi's comments on GPUTweak.
I need to spend some more time with it but it doesn't seem to work with this card

i cant seem to get any overclock whatsoever on my card, 1100mhz seems to be the best it does lyk :/ maby i just suck at overclocking these new cards. lol. i couldnt overclock the last 5870 i had either...
ok, so i tryed harder, got it at 1225mhz on the core 1325mv and 899mv VDDCI (not too sure what effect this will have) and 7000mhz memory 1650mv. stable on borderlands 2. (loadline calibration at 100% and power target at 120% are these right?) custom fan profile working, but its absolute bolloks with the square wave. not smooth atall!! what about VRM clock?

ASUS have said that every card should be able to do 1200 core at least and i believe them. Here's a simple overclock.
In GPU Tweak, put the power limit all the way up.
Core Voltage up to 1300
Slide the gpu core up to 1200MHz.
You should also be able to just slide the memory up to 7000 without doing anything else either.
Apply and test with Heaven for 20 minutes, if stable then save that overclock to a profile.

ok, ill try what you said as a simple overclock now

i know it wasnt 20 mins, but it seems stable. got to about 86 degrees on auto fan profile, i think im gonna remove my sound card seeing as i dont use it (its about 2mm from the fans of the 7970...i guess tht wont help huh? xD
Soldato
Indeed that will help!!
Ideally you'd want to keep the temperature below 80c. However, the te custom fan profile doesn't work properly.
You can bring the core voltage down in stages now, until it gets unstable the. Raise it up a little again. 1300mv is more than required but somewhere to start.

Out of interest what is the burn button for in GPU Tweak?

The "Burn" function writes the current settings straight to the BIOS so they will be completely default. Meaning you could find the perfect 24/7 overclock and fan profile, write it to the BIOS and uninstall GPU Tweak.
I don't suggest you use this just yet.
If it goes **** up then you can press the "Safe" button on the card itself which loads the factory defaults to the BIOS.
How's it going with GPU Tweak?
If you create a custom (User Define) fan profile does it link to the GPU temperature or VDDC temperature like mine does?
Also, does it do so only with Fan2? Leaving Fan1 escalating in speed exactly as the Auto setting does?
Great idea that burn button. I used to do that with previous cards, find a stable gaming core speed and voltage, modify the bios accordingly and flash. Then you can remove overclocming software. Shame you can't mod 79xx BIOSes

Indeed it's a fantastic option. I used it on the 580 Matrix Platinum and will certainly use it again, but only once i trust what GPU Tweak is telling me.

card seems ok lyk, dont think its THAT much faster than my 5870 at the end of the day, lol. cant believe i only got £70 in my pocket for selling it thanks to ebays monumental fees. most gutting thing about my purchase is i didnt get any of the free games that it was supposed to come with Emailed OCUK yesterday, but as of now, still no reply
