8.12 Cats, 4870X2 / Crossfire Systems! FIX

[ViRuS2k]

Well guys as you may know

a lot of people includeing me have run into the code 43 error
where 1 of your GPUs has been disabled.

I tryed everything i could think of to get the driver to install properly on my 4870X2

Here is how i fixed it, i know its not what you want to hear but this is what i did to fix my system

* Vista X64*
*ATI 8.12s *

-----------------------

Backup all your data and reinstall your operating system
Install chipset Drivers *reboot*
Install Framework 3.5 then 3.5 Sp1 *reboot*
Install latest Direct X
Go to windows Update * Install everything apart from languages *packs* unless you need 1 *reboot*

then finaly, install 8.12s, once your system reboots the drivers should be working perfectly with both GPUS in tact

-----------------------

I know, its a lot of time wasted but if you do what i said, your crossfire & 4870x2s should be working.

Hope this helps, you guys have no idea the things i tryed before following the steps above.

*WARNING* In future when new cats are released, do not driver sweep or clean sweep or .net drivercleaner pro your system or you could very well end up with the same error
to properly install new cats, its been said so from ati aswell, install the newest versions right over the top of your current versions, also if you need to uninstall them for what ever reason only use ati driver manager to uninstall them before reinstalling a new set, those are the only 2 ways to install cats 100% * WARNING END *

Glad you got it sorted, even if the solution was a little drastic

hehe yeah to this day i still couldnt tell you what was stop this driver from installing on my previous os install.

I do know this that its not the drivers that are at fault like everyone else thought, it must have been becuse of those ati driver cleaning programs lol
or a microsoft update becuse in the past month there has been a sh** load of them

anyway im glad i got it sorted in the end, i do know this the performance is far better and the desktop just seems smoother aswell compaired to 8.11s

i have noticed something though, i cant be sure but my cards temps with 8.12s have gone up at idle by 5c and probably higher in load aswell compaired to the 8.11s probably due to the fact these drivers work harder than the 8.11s

have you noticed your temps go up with this driver ?

anyway thanks for the help in the other forums and threads to try to fix this for each other unfortunatly though mine was a os reinstall and yours was a erm well proabably a fluke lol

It seemed to work fine for me when I installed yesterday, the installer went without a hitch.

Temps look same-ish.

yes you 2 guys but you foget some users didnt have problems.
this fix is for people with the 1gpu disabled when installing 8.12s

i know its annoying to reinstall your os but its the only sure fire way of fixing this problem at least for me it was a meny meny others.
