It isn't required. I read that the extra pins are only for ground. I got an adapter to run Overdrive from Performance PCs. You can get them customized with colored mesh.
http://www.performance-pcs.com/catal...d09a1c23f56ef1
I want to use overdrive to OC (well initially) as it doesn't increase the timings of the memory, and I can be sure that the OCing is stable. I am very weary of trusting 3rd party apps with a card this expensive....

Here is it straight from ATI's tech support. I asked about the 8pin connection:
Quote:
For optimal performance, and for ATI Overdrive and ATI CrossFire™configurations, use one 2x3-pin and one 2x4-pin PCIe™power connectors on a 750 watt or better power supply.

Any other questions, please contact us again.

So what Catalyst AI setting does everyone run? Advanced? I would think that advanced would be preferable...so any AA or AF tricks, tesselation, etc. can be utilized, but I dunno. I haven't seen much regarding it with our cards.

I leave everything default and just up clocks for 3Dmark. In games it's powerful enough as is.

Ok I found out that advanced Catalyst AI locks up the card in BF2142 (after extended periods of time)
FYI
Also, I keep everything at stock as well, except for the AA and AF, which I force in the CCC.

I'm running vista 32bit and 2900xt and when I run the AMD gpu clock tool the whole "options" area where the 2d and 3d check boxes are is greyed out... even the "same clock settings for all devices" part is greyed out and I can't click anything.

I need to figure this out because it seems that my 2900xt is always running in 2d mode even when I'm running a game.

Ati tool also doesn't seem to let me switch between 2d/3d modes either... I'll try to get it to find max gpu or ram clocks but it never changes the frequencies....

in fact ati tool keeps crashing on me when I try to start it... I can only use it once after a system restart then if I exit it just crashes and won't start up again until a system restart.

could the problem be that I have 2 6-pin pci-e power connectors plugged in instead of one 8-pin and one 6-pin? I'm using an OCZ 700w GameXtreme PSU.

if that's the problem would a 6-pin-to-8-pin pci-e power adapter work or do I need to buy a new PSU??

you can get a 6p to 8p and use cat to clock your card

Nope, I'm running the exact same PSU without the 8 pin adapter (yet) and I have no problems at all, even OCing. In my opinion, you either have a corrupt BIOS or a bad driver install. Also, make sure that you have the atihokeybpoller service running. This controls the 2d/3d clock switching. Run a 3d app and keep the amd clock tool open. Alt+tab out and see if the 3d clocks kicked in....you may need to start a support ticket with ATI, or RMA the card through the store that you bought the card.

Im not sure if anyone has posted something like this, but I cant really search through 64 pages. Im so proud

http://s6.photobucket.com/albums/y24...nt=holywow.jpg

I just tried a 3dmark06 run, and it did make a big difference, but I cant post the score, its the first FAQ on 3dmark06 on their page about why I cant. But for the duration of the tests, temperatures were <54C, with the stock cooler at 100%.

Are you running it with the little -command?

Just delete C:\\WINDOWS\\system32\\Futuremark\\dircppl.dll and it'll work fine.
