Hi everyone,
Sorry if this is an overstated question but i dont know what to do. I just recently built a new system with two XFX 5870s and what a surprise, the crossfire is not scaling well at all. I tested both cards to make sure each one worked individually, i tried different pci slots on the motherboard and even different crossfire cables. Ive tested almost every imaginable driver from Ati and still nothing. I am only seeing an increase fo about 5fps on all of my games, with the max increase being about 10fps, in BFBC2, the game with all the crossfire problems. What could be causing this issue and would swapping the cards out with a new set have any effect. XFX Customer Support is worthless, so that may be tough to do. Thanks!!!

Its critical to have your other system specs, if you have a low end processor than that would be limiting your FPS, also if your motherboard has a PCI-E 1.0 slot and install the other card makes it run at 4x instead of 16x, depending on the chipset.
One you tell us your full system specs we will be able to help you better.

The only game i have seen run correctly in crossfire is Medal of Honor, which should run very similar to BC2. I run Medal of Honor anywhere from 70 to 140, averaging around 80 fps. Where in BC2 i run it at about 50 with a single card and only 55-60 with crossfire, both dropping as low as 40 and with crossfire it should not drop to 40 with crossfire on unless there is a huge explosion. In crysis, with crossfire i run the game around 25-30 fps. Now i know crysis doesnt get along so well with AMD components but it should be well higher than that. All of this is even with the newest Crossfire Application Profiles.

Yes. I have 10.10 and have tried all the way back to 10.3. I also have the latest Crossfire Applications. I had an Alienware that i got before this for a real good deal which had two 5870s as well and very similar hardware to my current build. I sold it for more than i paid for it and built this computer, but my framerates were much higher with that system which is what sparked me asking this question

Download and install GPU-Z and go to the "Sensors" tab(open 2 copies of it in order to monitor each card).Then run a game for 10-15 minutes,then minimize it(don't close), and check the sensor's tab and the clock speed should be "850/1200", if its lower,then your cards have downclocking issue in CF mode.

I ran the trial version of 3DMark Vantage and recieved a graphics score of 24585, and after overclocking my processor and testing agian, a gpu score of 26155. The benchmarks for these two cards is around 24000 so the crossfire is obviously working. I would love to blame it on drivers but the same games ran significantly better on my old system. Unless my i7 920 at 3.2 made that much of a difference over my 1090T at 3.7. Im confused and dont know much about this stuff.

When playing games, both cards run at 800Mhz core and 1200Mhz memory so both cards are running at their full speeds. This is the first time i overclocked the processorjust to make sure that wasnt bottlenecking the games but that wasnt the issue so already went back to original processor settings. No change

My old system was an i7 920 overclocked to 3.2ghz, 2x asus 5870s, 12gb 1333mhz ram, and 825W PSU. I have a 750W PSU in this system now which is about as low as i could have gone. I do a lot of 3d modeling and rendering so thats why i chose the six core but now im thinking i should have got the 965 Black series. I know crysis doesnt scale well with the ati cards or even run well with amd components, but the fact that it runs 30 fps under what the benchmark is, i didnt think my cpu could bottleneck it that bad. Im playing the same games from my old system and some games like Bad Company 2 pretty much run the same fps. And i heard BFBC2 was pretty cpu dependent. Im also running GTA4 at about the same fps as my old system which is super CPU dependent.

Ya, i got 6 core because i built the computer mostly for rendering and 3d modeling but put those cards into it so my old games wouldnt go to waste. Im going to buy a new cooler around Christmas because ive heard these amd processors overclock very well and you can get this thing to over 4Ghz easily. Any recommendations for a cooler for this thin. AM3
