Solve : Crossfire Problem?

Answer»

I have a Diamond ATI 4870 video card and an XFX ATI 4870 video card, both with 1 GB of ram and I am having a terrible time Crossfiring them. The minimun wattage to do this, according to the manufacturers, is 600 and I have a 750 watt PSU. I plugged them both into the correct slots with the proper power cables and connected the TWO Crossfire strips. I downloaded a patch from XFX and upgraded the drivers. I have tested the PSU by unhooking my extra HD and DVD drive. I enabled Crossfire in the Catalyst Control Panel. I tried running each one alone and that was fine. I tried reversing the placement of each on the motherboard, which changed nothing.

Ok, when I play my game (Age of Conan Online) and it runs slower then with one video card and there is a constant flicker on the screen. So something isnt RIGHT. Anyone have this problem and corrected it or know what might be going on?

If it helps, here are the specs of the computer I am talking about:
Win Vista Home Premium...ASUS P5Q Deluxe Mobo...8 GB of 4-4-4-12 DDR2 Ram...Intel Core2 Duo E8400 CPU...one DVD writer...2 HDs (150GB and 500GB)...3 x 120mm fans. What about some patches or updates from Diamond?actually, you should download the updates from:

http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista32.aspx?type=2.4.1&product=2.4.1.3.36.3.2&lang=English&rev=9.6&ostype=Windows%20Vista%20-%2032-Bit%20Edition

It may help with the crossfire issue, it might not.Quote

Intel Core2 Duo E8400 CPU

Why would he want AMD drivers?Well, cuz AMD own ATI and they have drivers. However, like I said, I already got the latest drivers, so that wont help. But I am gonna contact Diamond and see what they have for patches So the problem is just with one game?
Look for a game patch ... failing that, disable Crossfire for that game, it SOUNDS like it's not a game that PLAYS well with Crossfire.maybe the game does not support crossfire? I dont know if thats possible but still , check it out...

I take it you went to the game producers bebsite and asked for support? if not do so tell them the exact problem , give them a dxdiag (start> run >dxdiag in xp cant help with vista )

Are you sure it isnt a power issue i mean the suggested wattage is 600 and you psu has 750 mabe a good idea to get 1kW psu? that would ensure you have the right wattage. Quote from: Nightguy on June 27, 2009, 08:45:24 AM

Doesn't matter who owns who ...drivers should only come from the OEM source.Quote

Thank you patio.

paudashlake,
It doesn't matter who owns the chipset, it's the manufacturer of the device that does the drivers.


Well, I always used ati for my ati card from his. His's site is a pain in the REAR to find anything on. It is hard enough just trying to find the right site. hahaQuote

I've never had a problem finding the correct driver on the correct site for any piece of hardware.LOL I cant believe you are so sensitive over the point that AMD owns ATI when the AMD site has the correct drivers since they ARE the OEM source and I have the drivers anyway, as I have said. The problem remains that Crossfire isnt working right and that is what I am needing help with.

Since I last posted I bought a 1000watt PSU and installed a Crossfire hotfix. Iwill check with AoC and see if they have a problem with Crossfire...thanks guys Hello all! Could it be that he has two differant card manufacturers - Diamond - XFX a possible conflict.....
