Crossfire Overclocking

[Arthalen]

Title says it all. Whats the best way of keeping Crossfire enabled and overclocking both of the cards ?

I have identically clocked cards (575/600), and want to push them as far as is possible, but what actual OC'ing tool works with Crossfire (and hence CCC, as I believe that is the only way to get Crossfire enabled ?).

Edit: I *really* need to update this stoopid signature.

I want to know this too.......my CCC just shows 1 card and the overclocking tab gives me a slider range of 621MHz to 621MHz DOH !

To be honest when I had a crossfire setup I found it didnt clock at all well in comparison to how each card perfomed ( in oc'ing terms) individually

I was also not convinced completely as I only had one bar for mem and one for the core in CCC which card I was oc'ing even though I had two cards crossfire enabled

At this time all ATI clocking tools outside CCC were not Crossfire enabled - not sure if this is still the case.

Hmm, this is my testing, ymmv.

AtiTool -
Crashes when setting clocks at 600mhz core and above with Beta16 pre4. Has a basic way of selecting cards though.

ATI Tray Tools -
Forget it. Might as well use CCC, as it can only handle a single card or Overdrive.

RivaTuner -
Has possibilities - you can select which card to interact with. Buggy in setting clocks however.
