Crossfire, friendly advice needed.

[Sh3rlock]

Right lads, my second 5870 arrived this morning so I am going to be installing this evening.

Any advice, or is it simply plug in and play ?

Is it worth a fresh install of windows 7, or will it work just fine ?

Help/advice is appreciated as i don't want to blow this !

I just set up crossfire with 2 4870's just put in the second card, turn on and ccc will come up with a crossfire box already ticked so just hit ok. Thats it.

yeah its very straight forward, as above, uve nothing to fear appart from cat 10.6
ive no issues with my 5870's using cat 10.4b but later drivers have caused problems for lots of peeps with a CF setup.
heres a link to DL 10.4b (driver version 8.74) i think they are the best to start with

Thanks, I will give those drivers a whirl.

Will run some benchmarks too, results will be posted this evening !

welcome to CF 5870's bro

Sorry to hijack thread mate, but if you have a crossfire set up, are you able to run eyefinity without the adapter (similer to how you run nVidias surround)?

I'd like to know as I will eventually go crossfire 5770s and I'd like to know if this would be a possibility.

Heaven benchmark of 1642.

Is that any good !?

If I set everything as high as I can on Heaven and use dx10 I get 1243 with 2 4890's.

1920x1200, 8xAA, 16xAF using the Cat 5a's.

I've found using later drivers than the 5a's truly dreadful, Heaven score drops down to 834 with the 10.7's !

ATI seem to have really screwed crossfire with the 10.6 and 10.7's, at least on my rig, hope they get it sorted soon.

 

[Sh3rlock]

when you say 5a's, does that mean the 10.5 hotfix drivers ?

 

[Jaggy]

Yes, sorry I've lost the link.

 

[Sh3rlock]

Its ok, ive got the Hotfix drivers installed anyway.
