This breaks consumer law in Australia, and is therefor invalid here, no matter what it says.

 

Edit: But it is sneaky and underhanded and just BS.

I haven't seen any proof. I just assume that they will/do. We should see full dcu2 reviews soon.

I need more than 1.3v. I'm running 1.3 as my standard now.

Ive also tried asus's gpu tweakit and trixx. neither of those will do anything.

Sounds like you need to uninstall all utilities and drivers, clean ati from reg, and reinstall drivers and the utility of your choice.

Edit2:

What was the cfg edit to make afterburner display actual voltage not target? I cant find it. And where the heck is my powertune slider? Do need to restart after installing beta 12?

So is the OCCT test more demanding then Kombustor?

I want to just stress test to make sure it passes clocks then play my favorite games to see if it is stable.

I will be using GPU-Z and log to make sure it is not throttling down the card.

I always run about 30 minutes of the Heaven benchmark, followed by about 20-30 minutes of the Crysis benchmark. If I pass both of those....I never have a problem with my GPU overclocks.

So installing latest MSI afterburner and now without tweaking voltage mine says 1112mv.

So I got unlucky and got the 2nd worse Asic version, as the best Asic is 1025mv?
so my maximum volt is then 1112mv + 125mv= 1237mv?

For now I'm going to overclock using stock volts 1112mv, I might get ballsy and try out 1175mv aswell.

I'm trying with Kombustor, then once it crashes I will decrease 25-50mhz, then game favorite games and Unigine 30min.

Once I order my waterblock I'll also try out maximum volt so 1237mv and also do another OC before I slap on watercooling.

So, on impulse, while doing some "business" at work today (if you know what I mean), I ordered a Diamond 7970 from Newegg. I was unaware the Asus DCII had hit the Egg, even though it is OOS. If I had known about that, I would have waited for that, simply for it coming with a back plate mad.gif

Is there going to be a back plate available soon for sale here on the US? I know EK has one, which is almost $70 shipped here. I saw Swiftech has one coming out, but I couldn't find any info if I'll be able to buy just the back plate, not the whole waterblock. Any other back plates surfacing? Or is that about it?

well i got my xfx hd7970 core edition to core 1150/1500 at 40c with fan at 40% and stock voltage however to bump anything more due to noise this card has to go under water so swiftech needs to get its waterblock out cause im gonna need 2 of em.

40c?

I'm running so far 1125/1375 and the temperature % fan seems to be similar to stock, but my temperature is around 77-78c.

I guess you want the Swiftech as it also has backplate unlike other watercooling?

Yeah 40C at those clocks with fan at just 40% is impossible. Must have been a typo.
I run 1125 / 1790 @ default voltages @ 68C @ 45% fan @ BF3.
