I recently crossfired 2 x ati hd 4870's problem is my machine doesnt really seem that great. Im only Scoring 12k on 3d mark 06 with crossfire enabled. If i disable i still score in the 11k's. Is there anything im not doing or that i should chane to make better. Im not satisfied with my performance. But it might just be me thinking i should get more than what i am. Ill list my specs and any one wanna note some things maybe i can do would be awesome. Also Please not im running xp 32bit.

im just not sure whats going on here maybe its jus me but my old board with the amd 5200+ seemed like it was 5 times faster.
 
Have you tried to see if the gaming is faster in actual games instead of 3DMark?

That Phenom maybe bottlenecking you a bit. I don't think it would cause that much of a issue. You should see a decent performance jump.

Make sure you also have the drivers installed properly. Did you have a old card installed before this one? Like a Nvidia one. If so do a driver cleaner wipe and reinstall the drive.

What motherboard are you using, is it the one from the old 5200+? You may have a bad crossfire board could be the issue,
 
I previous had a nvidia card but i unistalled all drivers prior to removing the card. heres whats strange is it says i only have 512mb of memory allocated for graphics but im using 2 x 512 cards shouldnt that be a 1024mb allocated for graphics. Jus dont see what the heck is going on here

mobo is a msi DKA790GX
 
Wow, someone else is running a 8750 !!! I thought I was the only one. Mine is a Black Edition and it's clocked at 3.01Ghz.

I would say you do have some problem. I have a single HD 3870 on an Asus M3A79-T, and my 3dmark'06 score is 11,700 ( with my cpu @3.01Ghz ).
Here's a review of your board. It might help.
http://www.overclockersclub.com/reviews/dka790gx/

First, the obvious questions.
What power supply are you using ?
- You might not have enough power for both cards ( + 3 harddrives, 2 optical drives, case fans, etc...).
Do you have your ram in dual channel ?
-According to the review site.... "Each color represents a channel and MSI recommends using the orange slots when running only two DIMM's for dual channel."
Did you use a driver cleaner program to completely remove the Nvidia drivers ?
-Sometimes there are driver conflicts if you do not completely remove the old drivers when going from Nvidia to ATI or vice versa.

One consideration is that your cpu bottlenecking your cards.

Lastly, 3dmark is only a benchmark for bragging purposes. Intel cpu's KILL AMD in benchmarks. A friend of mine and I both have rigs with crossfired 4850's. His rig is intel, mine is AMD. He scores about 2,000+ points more than me on 3dmark'06, but in Crysis at 1680 x 1050 with all the eye candy turned up, we're within 2-3 fps of each other.

First thing I noticed was the Ram not running Dual channel.

Boot up in safe mode and then run Driver Sweeper to take out the old drivers.
Then reboot and install the new drivers
 
ok thats odd i do have the ram in the orange slots. Also im running a corsair 750w power supply that is built to run sli/crossfire i have 4x 6outlet plugs ran striaght to graphics cards. I havent overclocked the processor yet because im using the stock heat sink right now. soon as i get better heat sink i will start ocing it. third i was far more impressed by the amd 5200+ im gonna try to switch the ram slots and reinstall windows completly and see what happens ill let you all know the out come.also 2 of the drives are external usb one hard drive and one is external light scribe so they both have independent power supplies. so in my machine im only actually have 2 sata drives and a dvd burner

sorry if i sound like a noob but i dont know how to get the fps in any games. any help any one.
 
Download fraps. You can record your FPS numbers to use as a benchmark.

ok you were right i goofed ganged and unganged never heard it worded this way in a bios when i set the ram to ganged mode (dual channel) my machine wont even post. what gives with that.
 
It's my understanding that the AMD cpus aren't fairing too well in terms of 3d performance (I have a Core 2 Quad), so keep that in mind if you're not comparing to similar cpus.

As for the video memory, when x-fired or sli-d, windows only sees one video card (this is the point - two cards functioning as one), and only recognizes the amount of on-board ram of the smaller/est card.

Strange i assumed it to be like striping hard drives 100gb = 200gb. So that my error there.
 
your prollum is your cpu if you had it at 4ghz+ those cards will really shine, thats the bottle neck under 3ghz really holds those cards back m8.
