Upgraded to SLI but 3DMark06 only went from 8958 to 9777. . . . Is that normal?

When I ran a single 8800GTS 640MB I scored 8958 in 3DMark06. When I put a second one in SLI I scored 9777. Is that a normal score increase for changing to SLI?

I'm wondering how I can make sure that SLI is enabled properly? I enabled it in the BIOS and changed the PCI-E bandwidth from 2-1-1-16 for a single card to 8-4-NC-8 for two cards. I installed the latest Nvidia Driver v163.75. I also enabled SLI in the nTune utility.

Here's what I see in the details page of 3DMark06 . . .

Is there a reason that it says "Linked Display Adaptors: False"? . . . Does that mean that it is not running in SLI? I installed the patch for the 1.1.0 patch but that didn't change anything. Any ideas?

Thanks!

its your chip holding you back

in your drivers sli enabled or disable is a option that you need to select.

oh ya ur opty holds back a sinlge 8800gts... 2 it will bottleneck it like crazy untill a res of ohhh 2048x1536...

Ok, I see what you guys mean . . .

I heard 3DMark03 is more GPU intensive. So I tried running it in single card mode and in SLI. I got 30,436 in single card mode and 42,368 in SLI. So I can tell that SLI is running. I guess it's just not helping much in 3DMark06.

Thanks for your help!

yep its your cpu holding u back alot, time to overclock it more or uprade

ocing it aint gonna do it... ull need a q6600 @ 3.6ghz to not bottleneck thoes tings

Lets not get all quad crazy here a E6750 will do the trick!

tbh... no ull be bottlenecked with a E6750 @ 3.6ghz with 2 8800gts 640's for sure.

its about at that point where a single 8800gts 640 stops becomming bottlenecked. with a C2D

Where do you get this from ?

What I would like to know is how someone is able to prove that the GPU or CPU is the bottleneck in a given system. In fact, can anyone explain how the CPU and GPU work together in a benchmark such that one could bottleneck the other? . . .

I mean, the video calculations are done in the GPU, so what exactly is the CPU doing that would increase or decrease that performance? I hope someone could offer some concrete insight on this. . . .

3dmark 06 uses all four cores, so a quad is truly needed for highest scores. But as we all know, it dosn't translate into games generally.

as for the post above. The cpu needs to process the information before passing it onto the GPU. If the CPU can supply more data than the GPU can process at any given moment, then the cpu is not a bottleneck. What you have atm is the GPU's waiting on the CPU to send it instructions on what to do next. On top of that, the CPU has the run the rest of the gaming enviroment, like physics etc. in 3dmark06 there are physics and other things involved. It a whole system test not just GPU.

If i remember correctly, if the cpu is the limiting factor, changing to a low resolution will give approximatly the same framerate as higher resolutions. (lower resolutions (800x600) stress the cpu a lot). basically you fps should scale with your res. if the cpu is the limit, then it won't.

couldnt say it better myself.

For an example of your CPU bottlenecking your system, I got 12572 in 3dmark06 with 1 8800GT and a [email protected].

What I would like to know is how someone is able to prove that the GPU or CPU is the bottleneck in a given system. In fact, can anyone explain how the CPU and GPU work together in a benchmark such that one could bottleneck the other? . . .

In 3dmark 06 you also get separate score's so you can see how low your weak link is. What was your CPU score? What were your shader scores?

I sorta thought that the lower score between the GPU and the shader scores indicated which was weaker as well, so for me my CPU is still the slower part because both shader scores are higher then my CPU score. But this is just supposition on the logical link between the scores.

Is there a reason that it says "Linked Display Adaptors: False"? . . . Does that mean that it is not running in SLI? I installed the patch for the 1.1.0 patch but that didn't change anything. A

Newer drivers might get this to report correctly.

White_Pawn · Nov 11, 2007

simply overclocking your opty 185 will dramatically increase your score. However, if you want maximium frame rates, you will need to get a better cpu. (and along with that a new mobo and ram.)

Drinkyoghurt · Nov 11, 2007

hmm i got 10500 on my single 8800gts 640mb so yeah its your cpu most definetly....

Thanks for the input, guys . . . That makes a lot of sense. I'm gonna see what I can pull out of this chip. I bought it from a friend who said he got 3.0GHz out of it on air. But I can't seem to break 2.7GHz! . . . When I have more time I'll put it under the water-cooled/TEC setup shown in my sig.

What's up! . . . I think my truck is just about in its "finishing stages" Here's how it still sits. . .

In a few weeks, I'll work on putting a traction bar and roll cage.

Upgraded to SLI but 3DMark06 only went from 8958 to 9777. Is that normal?
