1. My OC on my CPU is stable. I ran Prime95 for about a day, and no errors came up.
2. This computer was built from the ground up. New case, new PSU, new CPU, new MB, new HDDs, etc. So I had a fresh install of Vista. Every time I installed different drivers, I used Driver Sweeper after uninstalling the drivers through Control Panel.
3. None of my components are overheating.
4. Yes, Crossfire is enabled in CCC, and I have all four PCI-E 6-Pin connectors fitted correctly in the cards.
5. I removed one of the 4870s and I no longer have problems. I even switched the cards and performance was flawless.
6. Thus leading us back to the original point of this thread: Is CrossfireX really worth it, because the problem IS CrossfireX.

no .. there is NP with CrossfireX

it works really well and scales in *most* games. Do you have the bridge interconnect ?

I sense "fanboyism" right now. Can you provide any proof that CrossfireX doesn't have any issues? I just proved to you that CrossfireX IS the problem, because I'm only running one card right now, and it's working perfectly fine (And yes, when I had CrossfireX, I connected both bridges). So stop being subjective.

Proof to Who ?
--you could be completely incompetent for all i know

i did not say Crossfire does not have "any" issues

i said i HAVE crossfire .. since 2900xt . . . and 4870x2 is in my PC running without issue and scaling fine; i am going to try x3 very soon with my other 4870

i am about to throw my GTX280 into my PC and compare performance

so .. who is a fanboy?


try disconnecting a bridge and run with just one

"no .. there is NP with CrossfireX "

Proof to whom? I was just asking you to provide any evidence that backed up your statement which I just quoted above. And you stated that directly at my quote, giving me the impression that you were just being subjective, AKA a fanboy. Please be more clear with your statements.

And how am I even remotely showing any "fanboyism"? This is a blunt question. I will ask it again. "Since I am having issues with CrossfireX, and it seems that several other people that I have talked to (friends, co-workers, forum members, etc.) are having the same issues at times, I am beginning to think that maybe CrossfireX is not really worth the money. Also, only a few games that I play actually scales well with CrossfireX, e.g. Call of Duty 4. There are also some benchmarks on bit-tech.net showing this. In some games, CrossfireX does not show any signifcant performance gains. So should I keep my current setup and hope that game industries will add more multi-gpu support to their games and that ATI fixes their drivers, or sell off one of the cards and use one 4870, OR buy a GTX 280 (Whichever performs better at 1920x1200 resolution)?"

Thanks in advance to the people who won't assume that I am incompetent by asking me dumb questions such as, "Did you connect all of the 6-Pin Connectors?" Obviously I know what I'm doing. A moron wouldn't be toying with equipment as such.

Your experience is anectodal - which means we have to take your word that it does not work. Just as some are taking mine that it does.

i am in the *middle* of a HW review with 5 GPUs - 4870/4870x2/2900xt/8800GTX/GTX280

i am *exploring* X2 right now, and i see none of the issues you mention - except ONCE - with bad artifacting in QW-ET - it happened twice at 19x12 and never again

After i run all the GPUs thru about 30 individual game benchmarks, i will run 4870 + 4870x2 for Crossfire-x3; then i rebuild my PC with a X48 MB and redo X3 again. After that i can provide benchmarks that PROVE it scales [or not]

Until then, i am absolutely *certain* Crossfire HD4870X2 scales very well in about a dozen games i have played, 7 of which i have extensively benchmarked

Thank you. The only useful thing you've said.

You're welcome
With an original post as *Vague* as yours - and combatative to boot i tend to toss a LOT out there
- it is not like you want to learn, i.e. some people will buy Nvidia just to crap on it and you are brand new here - so we don't know you

I have a 4850 and a 4870 crossfire setup and am having very similar problems with the 4870 set-up. When it runs, daym, it screams, but it overheats so fast that I cant do too much with it. OTOH, the 4850 set up has been really good to me, it scales well and has stayed stable.

Heat issues are another problem - refrigerate your case

You update once a month .. unlike Nvidia's weird driver naming, timing and oddball releases with betas
:roll:
