Is Crossfire this bad ?

[Nicolas145]

I have 2 6870 on Crossfire and i think its having problem with Crysis, its set on medium yet it only hits 30fps, is it crossfire seriously this bad ?

This might sound like a stupid response. But have you got a crossfire bridge connected to the GPU? It is an orange looking thing going from one card to the other. If that isn't in place or isn't seated properly it can cause funny things to happen.

Good point, also try turning it around and trying again.

His Unigine Heaven benchmark does confirm crossfire works. His score doubled in crossfire mode. I don't believe that is the issue. It's likely something else in his system, perhaps underpowered PSU or as has been discussed to death, bottlenecking.

try using the 32-bit version of crysis ive heard if you do that than crossfire will yield much better results

Tried that, now i can run it maxed out with 4xAA, no Vsync, but afterburner now shows 90 usage of GPU1 and 0 of GPU2, what is the problem then ?

If you see a marked improvement in performance with crossfire, I'd ignore that. That percentage of use can be screwy and not always accurate.

Yes.
Unigene is not cpu intensive.
However with scaling it can show as i said about 6950 CFX only just coming in front of 1 480 with a phenom II at 3.8ghz.
That thread still exists (member system gallery).

I don't know about the tropics, but the heaven benchmark (which he used), does not get bottlenecked by CPU's at all from everything I've seen. I can run it at 2.67ghz and turbo off and get the exact same score as with 4.0ghz. Others have been testing even lower. Heaven does not bottleneck easily.

But tropics has about double the FPS as heaven, so it's easier to bottleneck.

I suggest he downloads MSI afterburner and uses the gpu OSD tool.

The percentage i told you was gotten by me using Afterburner's OSD

I had crossfire off, turned on, the fps is now 40, but the usage almost the same.

Like I say Phenom II CPUs are real good for gaming mate rock on AMD FTW.

Was that an improvement over single card performance?

Not really, in fact i lost 5 frames, and got some lags in moments where it had much stuff blowing up, while the single did not.

I doubt it's bottlenecking. OP, I know this might sound like a hassle, but as a final thing I could blame would be corrupted drivers. Unfortunately, the only way to fix that issue is reinstalling windows, would you mind doing it? It might fix all your problems altogether.

I can't do that now sorry, maybe when i buy a new HD and a external HD i will sure do it.

Do you guys think Overclocking my CPU to 4ghz would help ?

Thats generally why people buy an unlocked Black Edition Phenom II CPU

Do you think Asrock Motherboard's OOC overclock would do the trick ?

I don't know I have never used Asrock motherboards I hear they are good quality and value ect but you might want to research it before you get into it balls deep.

So, any tips here for me to overclock the CPU ?

Std. requirements of overclocking:
-motherboard with decent BIOS settings available
-multiplier unlocked CPU
-motherboard with quality, cooled VRMs
-aftermarket CPU heatsink/fan

There's a bunch of guides around for overclocking Black Edition Phenoms... some on toms and some on other sites - just read one of those that you find helpful.

Mine's standard i guess, by aftermarket you mean the default one or a custom, if its a custom i don't have one, but to compensate my CPU is being cooled by 3 fans.

 

[Nicolas145]

Don't overclock more than about 10% if you don't have a custom heatsink/fan. The stock heatsink cannot deal with the extra heat generated by overclocking - in particular, voltage increases.

But what about the stock fan + 2 fans ?

 

[Sunius]

It won't work, because the main cooling of the CPU is done by the heatsink, if it's small, no amount of fans will help, because the surface area will be too little for the increased heat.

even know the black editions are unlocked they still dont overclock to well and they heat up in a hurry.stock fans i would not go higher then 3.5 or 3.6 ghz plus the stock fans on those are ridiculously loud when they hit full load

Who says Phenom II BE heat up and THEY DO OVERCLOCK VERY WELL ! where are you getting your info from or I should say where are you getting your misinformation from.

He did mention on the stock HSF/fan setup. He'd definitely want an aftermarket HSF before he overclocks it a lot.

That does not mean the CPU is a hot running CPU that means you need the right tools for the job such as an aftermarket CPU cooler like the CM Hyper 212+ ect made foe Over Clocking. You cant bitch about fuel economy when you bought a 6.0L V8 4x4 pick em up truck ect just like you cant bitch about a warm runing CPU when OCed on the stock cooler. Well you could bitch but you would be Wrong !
