Sigh, yet another thread about Crossfire and the 3870x2

post #1 of 24
Thread Starter 
Ok, I'm getting some really weird results from 3dmark06. With a 3870x2 and a 3870 in crossfire I'm getting the same results as I was getting with just the 3870x2. The scores are 16.8k, which I was fine with on no OC on just the 3870x2. But when adding the 3870 there was zero change. In ccc it shows that crossfire is enabled but in GPU-z it is showing a drop down for each of the cards and showing 2 GPU's enabled not the three. This is with xp 32bit (switching to 64bit vista soon) and the 8.2 catalyst drivers. Any advice on this would be great, maybe I'm just being a crossfire noob and missing something.

I tried the 8.3 drivers when I first installed my 3870x2 and they were really bad for me. Tons of stuttering and the like.

yup you need the driver update known as the 8.3 Hotfix ATI released soon after, this removes the stuttering somewhat, but crossfire on the X2 is not enabled in 8.2, only in 8.3.

Hope this helps

Isn't there a hotfix available for the 8.3 drivers that the 3870x2's benefit from?

After switching to the 8.3 drivers it shows as crossfire x being enabled but the 3870 does not show up in ATi overdrive. Very annoying.

Just hit a new low, pulled in a 10k with both cards in and CrossfireX enabled. Something is seriously not right.

Whee, my first taste of ATi tech support was a riot. All the dude would talk about was Crossfire certified. Oh man, anyone have any ideas?
