Help with tri fire setting up.

[arc@css]

Hi,

I need some help with getting this to work, not sure if I have missed something out or not.

Both cards are attached with a crossfire bridge. I have my usual cable attached from the 4870x2 to the monitor. I am assuming you only need one cable going from the primary card to the monitor, unless you're running above 1920x1200, which I am not, yet.

Is there anything I need to do in CCC? I have just run a benchmark and it was no different from when I ran it with just my 4870x2.

If someone could provide a checklist or some pointers I'd be grateful.

Which benchmark program was you running? Not many can test multi-GPU very effectively. Download GPU-Z and see if it says crossfire is enabled there.

Yes, according to GPU-Z two gpu's are enabled but not three. I can't access anything in CCC which will allow me to control the fan speed for the new card. Sounds like a turbine atm.

Have you rebooted since installing the card? When I ran 4870 xfire the second card would spin up full at first.

Reinstall the drivers? Might've not installed properly for the 4870.

 

[arc@css]

nvm.

Yes, I have rebooted the PC. I might try reinstalling drivers tomorrow, can't be doing with it now. Using 10.4's atm. Spent enough time on it for one day. Thanks for the replies.

u need to reinstall drivers when going from dual to tri fire

yes reinstall the drivers, it should auto detect it in the catalyst centre but you may need to enable it after you reinstalled

The first thing I did was to take out my X2, put the new card in (to make sure it was working fine on its own). It needed new drivers so I uninstalled the 10.4's and thought I may as well try the 10.7's.

It Installed fine, tried the card in a few games then shut the PC down and finally added my X2 back in.

I then found it needed a reinstallation of drivers (reason I thought it might be okay was because on AMD's website the HD4xxx series appears to be under one roof for driver downloads). So, back to the 10.4's. Will try again tonight or tomorrow. Something doesn't seem right with the two psu 6 pin cables that the 4890 is using. They pull out too easily from the psu.

As a side note, I had to take my sound card out, just wasn't the room. Onboard audio seems way better than 'ok' as I imagined it would be, actually.
