personally, i'd go with AMD GPU Clock Tool hands down. it let me overclock my HD2900 1GB with only 2x 6-pin connectors. i was able to stabalize 850/1000. i got it to 850/1100, but that was in XP. Vista seems to have issues with oveclocking the RAM on the 1GB DDR4 version.

the only downside the AGCT, is that you cant run a stability test for the settings, you just have to run a demanding app and see if it jams or not.

Ahright cool, cheers i'll give that a go

Meh, it locks mine up too.....it's never really been something that I use. You aren't going to hurt the card by overclocking in CCC.....only increasing the voltage.
My backplate gets REALLY hot too....nothing to worry about there.

CCC locks me up when I let it try and find the max clocks...have yet to see that actually work...

[binormalkilla]

Yea it locked up on my X1950 Pro....lawl

work on xfx 680i SLI boards? how about the crossfire? I don't know anything about ati. always been nvidia... but this card rules!! any help would be nice.

Ok, maybe I've been doing it wrong but for me (and this is true on my 1900xtx, 1950xtx and my 2900xt), ccc runs the card harder and harder until it locks up, then sometimes bsod, restart and the clock is set to a couple of mhz before the bsod. Go back into overdrive and select preserve at startup and you're set.

Note, the lockup happens twice usually, once when oc'ing the gpu and once when oc'ing the memory.

I haven't tried anything but ccc on my 2900 but on the other two cards, I wasn't able to push them any further with atitool. Keep in mind that this is "my" experience and I am no expert so human error may be a factor in my limited use of atitool but I've always had excellent oc's with ccc.

EDIT: Oh, and I always leave pci-e frequency at 101. I've run 3dmark and on every setting between 101 and 118 with absolutely NO gain.

So what did ccc lock your 2900 card up at??? Just curious!

[tr8rjohnk]

In Vista, it sets my gpu to 858mhz and memory stays at 1000. In XP, Gpu at 853 and memory at 1145mhz. This is one the same rig (dual-boot).

Thank god, would've been distraught if id hurt it! considering how much it cost!
