I just dropped the coin for a new ATI Radeon HD 4870 X2 and I am so far disappointed. It installed well enough and the games I play look fatastic. But I expected to be able to turn up WoW to all the max settings and have it look beautiful. For the most part it does but the game STILL bogs down in certain scenarios.

I decided to check out Device Manager and much to my surprise, only one GPU is enabled. The second GPU is disabled with the following error -

Windows has stopped this device because it reported problems (Code 43)

In the Event log I also have an error -

At least one display adapter on the system has been disabled because its drive is not compatible with the driver fopr the VGA adapter.

I have pulled down the latest Catalyst driver from ATI/AMD and still have the issue.

My system in Vista Ultimate x64 Intl Quad Core CPU with 8 gigs of RAM

(Yes....I am using the 64 bit Caztalyst Driver pack)

8.12 crossfire is somehow messed up in wista, try 8.11 instead...
You can apparently get it to work with little tinkering:

Ati has allready released a hotfix for 4850 crossfire, maybe the one for 4870 is still in the works

Thanks! Working through the thread now!

BTW...looks like there is a 4870 Hotfix.


Will worry about that if the thread doesn't resolve

bwhahahaha I run wow maxed and raid with 30+fps on a Athlon 64 X2 6000+ and a 4670 with 2gig of ddr2 667, it is one of the easiest games for a computer to run since the code used in the graphics has not had a major upgrade since 2005.

there is no way that even if only one core is active that a 4870 x2 , 500 doller card (cost more than my whole computer) cant run wow.

It runs it VERY well in every scenario and most of the time at 60FPS. It only drops during a flight between cities. I believe that is because of the distance setting and trying to resolve distant objects.

Regardless, I just want to get the 2nd GPU running so I can get what I paid for. I will post more specs here once it is up and running.

yup i agree. Driver, ATI seems to be working on this.

Regardless of the driver issue.... even a single 4870 core on crutches should annihilate WoW. If you're experiencing any stutter or low FPS it's probably a latency issue (unless of course this ATI driver issue goes beyond disabling 1 GPU).

Sounds like folks have you on the right track though. :)

I have resolved this issue per the thread I referenced. I no longer have any stutter anywhere on any game. WoW runs at no less than 40 FPS anywwhere in the game that I can tell with everything cranked to the max.
