  • Delete these folder;
  • C:\user\Program files or (x86)\ ATI or AMD.
  • C:\user\ProgramData\ATI or AMD (need to show hidden files).
  • Turn off UAC.

    Go to Control Panel > User Accounts > change User Account Control Settings > move the slider to bottom > restart PC.

  • Re-install everything. Note; Afteburner, Trixx or Asus Tweak should be the last. Do not override them with Catalyst install. 

I'll try this right now but there should only be 2 folders there right? I don't need to re flash the stock then flash the asus oc one as well too right?

First of all -- I got rid of Afterburner and got Trix -- It's more pleasing on the eyes and does everything I need it to. That said, my good clocker card can do 1125/1575 without any bumps on the voltage no problems
My 2nd card, the dud is very problematic. If I give it 1.2volts and keep temps cool, I crash quickly at 1125/1575 and can barely even get a test up. If I give it bump from the stock 1.17 to a 1.175 it ran for 1,333.9 in OCCT with 2 errors before locking up the computer.
What the heck is giving in on this thing? Is it just being that picky with clocks vs voltage? Is it really THAT bad of a clocker and I'm not going to see 1125/1575 at all on that card -- Maybe I ought to just send it back and get a replacement?
Help me out -- I want those clocks gosh darnit thumb.gif


I'm no expert, but try the second card installed stand-alone in the first PCI-e slot and see if the results are any different. Just a thought...

I love this card! I think I gonna use 1200/1600 for ordinary gaming. I had to crank the voltage to 1.218, or tiny artifacts would appear in BF3 after a while smile.gif

Here are the Metro 2033 results at 1080p (even though it says 2560x1600 in the title). Same clocks of 1390/1600.

Bloody hell! Wooooooooooooooooooow!!! Reminds me of the idiot/troll on the WP forums this morning that said the 7xxx series are an "epic fail" for AMD. lollllllllz NOT!!!

hmmm so logic and sensibility would say wait a few months for the price drops and all the new cards to hit...but I have the funds now... and who really uses logic when buying a video card lol?

 

So as long as I can get a decent O/C with the reference card I'm happy with that. But as I run 2 monitors all day I'm slightly worried,as I saw a thread where it was mentioned that idle temps of 60 deg are normal in that scenario... yikes! And even if around 80 is not dangerous, I rarely go above 60 with my 1000/1250 Asus 6870 even in Batman AC etc. So up there in the 80's seems a bit scary to me.

 

So as I understand it - the current "non-reference" cards the XFX and Gigabyte are really ref cards with a different cooler. So the O/C potential is the same, with only different temperatures and noise.

 

So I go for the Gigabyte O/C card with all that extra heat in the case but less noise and overall lower temps, or the Sapphire at the lower cost with more noise and those "scary" high temps.

 

Nearly ready to make a decision, but grateful for any further opinions or comments!

 

PS on My Sapphire 5770 and Asus 6870, 40%-60% has been the optimal fan speed. Above that and the temp gains are negligible vs the extra noise. Is this the same with reference coolers?

 

PPS My first ever 3D card was the "mighty" nVidea 9400GT (Passive), which with a humungous O/C ran in the 90's all day lol... doh.gif

 

PPPS I'm in Australia so all temps are in deg C.

 

PPPPS 2 x Asus DCII 6870's coming on the market real soon! :D



Sorry to be an annoying prick, but I am languishing on my decision to order the Sapphire. I can afford it, but $750 bucks is such a huge chunk of money :s I can get 2 x 27" monitors for that with change...

 

So convince me! buttkick.gif

Yes.

 

No, just straight flash with ASUS BIOS.

Well... some more info on my situation. I bumped voltage from 1.175 to 1.181 and it ran without errors for 30minutes at 1125/1575 on both. I think that's stable..... I hope

Will try playing around with it later some more. I know this baby can do 1200/1600 like my first card -- It's just real picky on the voltage/clocks even without crossfire enabled. If I add too much voltage and temps are fine, it bsods out.

I've been extremely impressed with the overclocking headroom of these cards. Makes me laugh too when I see people dogging on the 7000 series. They are only 20-25% faster than the 580 at stock but with overclocking they really stretch their legs. Can't wait for the custom PCB 7970's to show up. An extra power phase + dual 8-pin connectors should make things really interesting. biggrin.gif

Not so much whether Crossfire is enabled or not, but the different PCI-e lanes can have (very) minor vaguaries and temperature differences due to position in the case. Might be worth a try.
