Open services.msc & Disable the ATI Hotkey Poller, then reboot. You should be able to overclock both cards after that.
Nice 3dM06 score
Thank you, I managed to reach about 16,249, but lost the "magic combination".
By this I mean I'm about sick of trying to figure this damn Crossfire thing out and am selling my extra 2900XT. Seriously. Who wants to buy it?
ATI has some srious problems when it comes to predicting how your system is going to react to minor changes in CCC and/or whatever program you are using to control clocks and fan speed.
Ok, BioShock looks and runs great, but it did before CF too . Stalker took a HUGE dive when it came to CF, even when it was disabled! I didn't try any more. Why? I was too busy trying to get it to run correctly!!!!!!!!
Couldn't really get a solid average out of this configuration. Seems like 7.11 works best as far as ATI goes, but Riva and ATI Tool .27 b4 are hard to use along with CCC with CF enabled. Fan speeds always dropping back down to default on the main card, the 2nd card took to the fan speed change just fine and stayed "saved" on 100% duty.
Just WAY TOO MANY things to keep checking and changing and monitoring and tweaking. Too many variables and mixed results. I don't know if the problem is just me or my setup. I've seen Commando's advertised as 2x16x PCI-E
and 16x/4x? Mine seems to be 16x/4x. Maybe that's it?
These cards run GREAT by themselves, but together they have been just a headache and a waste of time and money.
Before I put this card up on E-Bay, i'll offer it here, if that's allowed.
One Sapphire HD2900XT 1GB PCI-E Video Card. Cleaned, well maintained, never put through horrible torture. I will also re-applie the GPU TIM with Shin-Etsu X-23. I can guarantee this card is in great condition, I wouldn't sell a half cooked card. I've had it for less than 2 months and it was bought new.
I have all the cables and everything else that came with it.
Any serious offers can just send me a private message, or leave one here?
However you wanna do it, but all payments are through Payapl. I'll wait about a week and then i'll put it on E-Bay if I haven't recieved any serious offers. They are kinda hard to find and still sell for $400 or more, I want to sell for alot less.
