i´m about to buy two 2900pro cards to replace my old x1800xt´s.
so i was taking a look at the ati homepage to see if they are cf-certified. but on that certified products page, there are only 2900xt´s not a single pro card.
i´m going to buy the sapphire 512mb version.
does the 2900pro come with an internal connector (bridge) like the xt?
does it work in crossfire at all, even without a flash to xt?

First off, Hello.
I purchased a Sapphire 2900PRO 1GB and its great, couple of questions.
I'm running under Vista x64, usuing Rivatunner to overclock and monitor temperatures and voltage.
In 2D the card runs 1.00v and in 3D it runs 1.10v, I've seen others who state their cards run 1.15v in 3D, is this because I'm running 2x6pin PCIe plugs and will running 1x8pin and 1x6pin unlock the 1.15v? Or is this just my BIOS, I've tried another BIOS, ATI XT and same thing happens, will a different BIOS from maybe HIS work?
At 1.10v in 3D I'm at 840 core, stable. But if there is more in her I'd like to try.
Welcome and sweet nick![]()
Whoa, the bad news is that you're now the second to report only 1.1. The good news is that it's stable at 840 with only 1.1vWhat did you use to test and for how long?
My 1GB is 1.15 using only 6+6 and unstable above 830. Others have 1.2v and can go higher. Interesting that the BIOS change didn't affect it, though it doesn't always of course. Couldn't hurt to try another. Is there a HIS 1GB?
Most people have 512s here so haven't been as many that have flashed 1GBs so there's less definitive info for us. Good luck and let us know how it unfolds.

Greetings everyone,
first off my rig is below:
AMD 6000+
Sapphire HD 2900 pro (now XT)
4GB Gskill 6400
ASUS M2N microboard
I successfully flashed my sapphire 512-bit HD2900 pro to an XT. and ran it flawlessly on my XPsp2 setup. Everything was fine and running beautiful until I decided to install Vista.
First I installed vista x86 ultimante edition, ive been runing it on my laptop for over a year so i decided to put it on my desktop to experience dx10. After my mobo driver installs etc everything was fine and works great.
However as soon as I installed the vista ATI Readon 2900 series drivers it says it completed sucessfuly then it props for an installation report which says my chip is a RS690 (don't know if thats relevant) with some other info. Upon restart nothing changed. First thing I noticed was I couldnt' and still can't access the control panel in anyway. Windows welcome center refuses to launch, and windows takes a quite some time to load upon start up. This is very frustrating. I tried to go back in and uninstall the drivers just to find out windows doesnt recognize my videocard.
I didn't think this was a big deal since I wanted to install the x64 bit edition to utilize all 4GB of RAM but after same install same thing. Can't access control panel, welcome center or anything that has to do with my computer hardware. everythig else works fine. I have not updated my windows yet however I didn't think that would have anything to do with my video card being recognized.
any help would be greatly apperciated.
Is that fact that I cant even get 10k in 3dmark06 because of my x2 chip?
Anywho, what voltages have you guys settled on as the safe range for these cards? My card doesnt like to go much over 800/950. Its really hard to find the max though since only 3dmark06 will show any errors and I only have the free version that takes forever to run. Even then it doesnt artifact, it just crashes.
