ok i just had xfire up and running just fine (required stock clocks to work) but now nothing i have rebooted shut down and powered back and still no xfire....this is very annoying im on cats 8.4 in XP 32 think i should try cat 8.2?

The 8.4's should work. I would uninstall the drivers and before you reboot, delete the ATi folder on your system drive (default), then go into your Windows folder and find the temp and prefetch folders and delete everything. (If you have disk indexing off, there might not be anything in the prefetch folder). Shut down. Install one card, start-up, install catalyst. Then shut down and install the other card, start-up and XP will basically install the driver for the second card, give it a minute or so... Shut down, install bridges, start up, and go into CCC, enable crossfire and you should be good.

Everyone having problems with crossfire should try this method as it works for me with XP and Vista with good success. Another thing is, if you decide for some reason to swap cards from one slot to the other, or just decide to use one card, reinstall your drivers. :toast:

Don't go that far yet! :laugh:

The things that come to mind are, bad crossfire bridge(s), bad card, chipset drivers not up to date or something is missing, other drivers not up to date or missing, perhaps a setting in your motherboard's bios for dual gfx cards, DX9/10 not up to date. I don't know what motherboard or OS you are using. Fill out your system specs in the User Control Panel. :toast:

Im guessing its a setting in bios

the P35s that I have worked on have a setting for dual cards. Those were gigabyte mobos, that could be it!

It was called crosstalk or something like that

Filled out my spec!

Could the fact that my processor is not fully supported by ASUS yet have anything to do with crossfire not working?

I've tested both cards and they seem fine? I take it a simple continuity test on the bridge pins will prove if they are working or not?

Thanks

Paul :rockout:

erocker · May 1, 2008

Did you look, or are there any settings in the bios to enable two cards?

Wonderloaf · May 1, 2008

I couldn't see any settings to enable both cards, there is nothing in the mobo user manual either, its shows crossfire to be pretty much plug and play (plug and pray in my case!

)

erocker · May 1, 2008

Can you post of screenshot of cpu-z, gpu-z, and CCC? PrintScreen>Paint>save as .jpg>upload it with TPU's free image hosting, the copy and paste the url to your post. If you don't know how to do that already.

cdawall · May 1, 2008

still a no go for me as well....

xfire works off a cold boot though its weird

Wonderloaf · May 1, 2008

Heres a few shots of what you asked for, it doesn't mean that much to me lol

Is that enough info?

Paul

cdawall · May 1, 2008

it doesn't see your second card is the card plugged into the PSU with the 6 pin connector?

erocker · May 1, 2008

Does it give you any messages under diagnostics in CCC? Try insterting the driver disk that came with your motherboards with both cards in. The mobo's may be missing the drivers necessary for both cards to work.

Wonderloaf · May 1, 2008

The primary card has both 8pin and 6 pin connected. The slave card has two 6 pins connected as my psu doesn't have another 8 pin spare...

Diagnostics is just blank mate?

cdawall · May 1, 2008

does device manager see it?

Might want to try pulling the extra two pins out of the master, just so everything is "even", though I doubt it's the problem.

Shows two in device manager

I'll give that a bash now! :toast:

erocker · May 1, 2008

You are missing a driver in "other devices", could be the pci-e bridge driver keeping crossfire from working. Did you "unlock" overdrive? Once unlocked you should be able to see both cards via the second drop down menu.

Wonderloaf · May 1, 2008

Just unlocked overdrive, i can now see both cards in the pull down menu!

Missing driver was "ATI T200 Unified AVStream Driver" whatever that is!
