5870 xfire users help please

hi i have 2 5870s one XFX and one powercolor they are both connected by one bridge about to try 2 now for the first time.

I have issues with a few games :
cod mw2
left 4 dead 2
aion
Dragon ages origins
Resident evil 5 plays super smooth with xfire enabled with no stutters at all.

Left 4 dead 2 is the worst stuttering especially when u are in the safe house and ready to start a new mission, the frames plummet and if i press escape to the menu and turn off multicore game is back to normal with the occasional stutter?

I get stuttering with a few other game listed above or maybe micro stuttering not sure how to tell,ive tried loads of drivers also.
I know the 5870 is a new card and no official drivers till tomorrow,im just wondering if anyone else has a problem with xfire or maybe its windows 7 X64?
I know most games do not suffer at all when one gpu is being used.
ive tryed both standard and advanced in cat ai.
Temps are fine for both cards and dont go over 80c
ive got to the stage where im seriously thinking of selling one 5870 if this carrys on.

Crossfire is rubbish im learning. Cod WaW does not run well with it as does a number of games i have tried.

I read somewhere that there is little difference between xfire with 1 or 2 connectors. Hopefully the next drivers will show an improvement with the HD 5890 being released.

How are the Xfire HD5870 temps now since you changed the motherboard compared to the ud3r?

just a update when i use just one gpu no stuttering at all in any games so its defo a crossfire issue?

Crossfire mate been getting the same problem today in cod WAW and bioshock. Ati need to get the acts together with the drivers. Not sure if it is down to windows 7.

hi are you having the same issues as me with several games?

If you read my thread in the graphics card section on world at war you will realise crossfire does not like a lot of games.

well the official 9.11s are a lot better now for me for crossfire not 100% but miles better

dmxdex2020 · 17 Nov 2009 at 19:17

Cool im just installing them now.

dmxdex2020 · 17 Nov 2009 at 19:33

Still got same issues.

I have 5870 CF with W7 and no issues at all

Have you tried altering PCIe frequency in BIOS ?

dmxdex2020 · 17 Nov 2009 at 19:59

Yea i got it at 100. I think cod waw is just not good in crossfire.

{SAS}TB · 17 Nov 2009 at 20:01

you tried at 101 ?

dmxdex2020 · 17 Nov 2009 at 20:04

Doubt 101 would make any difference.

{SAS}TB · 17 Nov 2009 at 20:07

It did for me with my old 8800GTX SLI set up, I had bad stuttering and reduced FPS, changing to 101 they ran sweet as a nut

i dont believe it

i have just changed the pcie bus freq to 101 and my stuttering is completely gone,thanks for the great tip!
Briefly why has they solved my issues with crossfire?.

Did not work for me. WaW is no doubt a badly coded game for multi gpu setup.

Just tried bioshock and that still has fps issues. that is an older game though. I need to install better games lol i just cannot be arsed. FEAR 2 is the most recent game i have. And i remember that ran fine with crossfire.
