3dMark 13185

Is this a good/bad or average score for 3dMark the free version on my rig? I'm not sure my sli is working properly though as I get roughly the same score whether I enable or disable sli mode.

Intel Core 2 Quad Pro Q660
4Gb PC2-8500 1066MHz SLI-Ready Edition Dual Channel DDR2
X2 Seagate Barracuda 7200.11 500Gb SATAII 32MB Cache.

EVGA nForce 680i SLI 775 A1
Enermax Infiniti 720W EIN720AWT ATX2.2 Modular SLI Compliant PSU

Sounds like you have made some progress since this other thread you started where your score was 6006.

Speaking of which I'm thinking it may have been better for you to have continued updating in that thread so those who tried to help you and others who would read that thread while doing their own troubleshooting would know what fixed your problems.

Not good... you should be 15k+ with SLI'ed GTX's.

Idk how good you are with computers, so ill say the usual.

1. Enough power to them both? 2x PCI-E connectors for each is needed.
2. SLI Bridge attached?
3. Updated drivers?

Make sure the nvidia control panel is set to "Let application decide".

But I honestly doubt thats the problem, and I believe I know what is and the solution.

Make sure you install those hotfixes for Vista64. I got a feeling that will solve your problem.

EDIT: After reading past comments, you DO need BOTH of the 6pin connectors in BOTH cards for it to work. So tahts 4x connectors, your PSU has 3, so use a 2x molex to PCI-E adapter for the 4th one.

it depends on which OS you're using.
under XP 3dmark06 gives over 15k
under Vista 3dmark06 gives around 13k

Yeah vista will throw your score down a little, but I score a 11800 with a single 8800gts 320mb...in windows vista 64.
First thing I would recommend is linking your results to 3dmark06. Are you using the default settings?
Second, I would take out one graphics card at a time. See if they both get the same score...if one is dramatically lower than the other you know you have a card problem.
Third, is your processor stock? Overclocking will increase scores considerably with that setup.
Hope that helps.

I'm running vista x64 with 3dmarks 06, I'm sure that the problem is within sli. I would try those hotfixes that hatman posted.

Hi guys - Actually those marks were on Windows XP 32-Bit. I have just installed Windows Vista 64-Bit again, patched up the hotfix drivers like Hatman said (thanks), and installed the latest nForce Beta Driver 163.75.
I have run 3dMark with both cards in and sli enabled and I got 11243. I then took one card out and run 3dMark and got 11315. I then took that card out and put the other one in its place and scored 11349.
So the cards seem ok, although the scores I think are quite low for one card and extremely low for both!!
I have put the 6-pin power cables into all four slots in both cards so I believe they're getting enough power, I hope...

Could perhaps my sli bridge not be working properly? But then surely it is working because when I switch on my computer with both cards in, a popup message tell me this machine is sli capable and asks me to enable it.

As you know I have two power slots for each of my gpus, but, I also have two sli bridge slots aswell... should I be linking these cards up with two bridges? I think not, but then I don't know what else to try.

I'm really lost...

have the monitor cable plugged into the lower 2nd GPU, and having the SLI bridge pointing upwards, so you can read "SLI" fine. It doesnt need 2x bridges thats for tri-sli.

Idk if that would help, this situation is confusing.

GPU-EX should be enabled. And obviously SLI should be enabled lol.

I think that possibly it's something to do with my PSU so I'm going to oder this baby (Turbo Cool 1KW-SR 1000W Power Supply)
What do you guys think?

I'm sure I'll benefit having a 1000KW PSU in my rig

My score with two 8800GTXs was 16,427. But i now have two 8800Ultras and with a mild oc[ 3.2GHz] to myQX6800 I scored 17,554
Does the nividia control panel say that SLI is enabled?Also make sure your SLI bridge is pushed in all the way. Go into your windows control panel and under system make sure its showing both GTXs. You could also uninstalling your cards drivers and reinstalling them.Make sure your virus protection is turned off frist before you install the drivers.

Only 3.2 Ghz on TEC cooling?? Push that 'ish up!

Its pretty easy to get way up in the clocks with pretty advanced cooling such as phase, LN2, TEC+water, etc..

These are people just aiming to set records.

I think that someone is out to get you and doesn't want you running SLi, made any enemies lately? perhaps flaunting SLi'ed 8800's in their face?
