I not only turned off overclocking in CCC, but also stopped CCC from loading at start-up. Still I get the "fail" message for the card in slot 0. The same card by itself (no xfire) in slot zero, OCs fine. :confused:Quote:

tbh i had most sucess with 8.7 beta because theyr driver is newer than that in the 8.7 final, but someone says 8.6 hotfixed is better for them .. Try both of them, or all three of them
Just because it has a higher driver number doesn't mean it's newer than the 8.7's It seems unanimous that 8.7 whql's are the best.Quote:

AMD GPU Clock Tool v0.9.8Quote:

That shows alot of promise to me specially with how big of an improvement overclocking brings. 1 review of it showed a 12% oc gave like almost even gain or something like that.
How can i overclock (+800 on core) with the fan at custom speed?
I tried 830mhz with automatic rpms and 3dmark '06 crashes with the high temps :rolleyes:
Is ATI Tool still a good utility for stress testing new GPUs?
Any news on this one gundamit? Having same issue its doin me head in :confused:Quote:

so I flashed the asus top bios and got my cards going at 885/1075 (vmodded of course) and I was able to pull this beauty out of my hat. :D

It's the highest O6 score on vista for 4870's that isnt a qx9650. Seeing as I don't have $800 (ebay) for one of those, I am extremely pleased with my result. (I even beat some qx9650's as well)

sorry for large size ;)
Very nice! This reminds me of when i volt-modded my 3870 to get the core up to 980 which resulted in just under 14k in 3dmark06.Quote:

But I think i'm just gonna wait and return my Gx2 for the 4870x2 ^.^
Just flashed my cards with the ASUS bios but set stock clocks to 825/1000, running much cooler but still fairly quite :)
what are safe voltages for GPU?
what sort of voltages are ppl using to get to 875-900mhz?
update on my temps. i ran GRID in a very warm room today (82°F or 28°C) and my cards ran at 72°C with the fans going at 3200 RPM. still very quiet. i didn't check the percentage, but it was obviously lower than 45% because i know what that sounds like. i just want to reiterate how much i like this fan profile.Quote:

This is before I watercooled it ignore VRM temps because I couldnt even run furmark with stock cooler so i had to settle for atitool

By turboz22l at 2008-07-30
and now after the water cool running furmark stable no crashing VRM is still up there but it was flaoting between 124 and 126 and who knows if everest is right or if gpu-z is recording the right temps. comparing the gpu-z temps tho its incredible results running at 790 clock 1080 memory just from CCC now time to voltmod see how far I can take this card. all results are in 80F ambient temperature room!

the second shot is the same as the first....
yeah I fudged up links I edited them I had last 2 shots the same as well sorry bout that fixed now.
looks great man, if you want any voltmod pics check the worklog in my sig ;) :up:
Thanks man ill take a look :-)
This is what i managed with volt modded 4870s in CF. Artifact free of course :). I'd like to see more, but they won't give it to me!

WoW nice clock on the GPU there what kinda temps you running ? and what voltages you using?
