3DMark03 and 06 lower result in SLI ???

[Oldjazz]

Hi all!

Does someone can help me with this?
with 3DMark03 card 1 result are: 10059
with 3DMark03 card 2 result are: 10058
with 3DMark06 card 1 result are: 5139
with 3DMark06 card 2 result are: 5166
with 3DMark03 2 cards in SLI acticated result are: 9980
with 3DMark06 2 cards in SLI acticated result are: 5021

So I'm getting lower result than with only one card.


Asus A8N32-SLI Deluxe "1303 Bios"
AMD Athlon 4200+ X2
Corsair 3500LLPro 2048meg (2 x 1024) in Dual Channel set up at 2.3.2.6 - 1T
2 x Leadtek 7900 GTX 512meg (each)
running them on Nvidia latest drivers (92.91)
Ultra 600w SLI ready power supply
Viewsonic VX922 monitor in 1280 x 1024 60Hz
Windows XP Pro
2 x Sata hard drive
1 x Sata2 hard drive

Best Regards.
Andre.

Did you enable SLI in the drivers?

 

[lopri]

Did you check the box saying "Enable SLI Multi-GPU"? Connect the bridge? Feeding both GTXs w/ 6-pin power connectors? Leave everything video-related in BIOS @default/normal? Try a different set of drivers? Low scores only occur in 3DMark03 and 06? What about 01 and 05?

Here is some answers

Antialiasing settings SLI8x
Anisotropic filtering 16x
Image settings High quality
color profile Not avalable
Vertical sync Off
Force mipmaps Trilinear
Conformant texture clamp On
Extension limit Off
Hardware acceleration Single display mode
Trilinear optimization Off
Anisotropic mip filter optimization Off
Anisotropic sample optimization Off
Gamma correct antialiasing Off
Transparency antialiasing supersampling
Triple buffering On
SLI rendering mode SLI antialiasing
Negative LOD bias Clamp
Threaded optimization Auto
OpenGL error reporting Off

Yep the checkbox SLI enable is checked.
Yep the Bridge between my 2 cards is connected.
Yep both 6 pins power connectors are connected.
I've tried at least 6 different drivers and that set of drivers are the fastest for now
92.91 drivers

You've got supersampling, SLI8x AA, 16x HQ AF, etc on. Lower all the image quality settings as low as they can go and turn on optmizations and see what you get.

8X SLI MY GOODNESS

Everyone's scores that you see posted here are with max optimizations and the default settings with no AA/AF.
Give that a try with both SLI and non SLI cards.

FIXED...now try those settings you should see a very nice improvement in your scores :thumbsup:

Does that board use a SLI selector card (or something) to switch between single and dual gpus? Mine does, but I'm looking at a picture of yours now and I don't see anything like that. Is there a jumper or a bios setting, or is it just automatic? Also, did you plug in the four pin molex connector on the mobo (located near the 24pin connection) I'm an sli noob also

 

[Oldjazz]

Yep j511180 the 4 pins molex is connected and an other 4 pins connecter for the EZ-Plug

I've modify the setup of Nvidia control panel and here is the results :

with 3DMark03 1 card result are:................................ 17608
with 3DMark03 2 cards in SLI activated result are:....... 20391
with 3DMark06 1 card result are:......................... 5927
with 3DMark06 2 cards in SLI activated result are: 5274

So it is a bit faster BUT with 3DMark06 I still get lower result in SLI than in single card.

Any hint for that lower result in SLI ?

Something is very wrong here. You should be getting 8000+ in 06. Enable the load balancing monitor. Does it appear on screen? How does it look? I've seen errors in 06, my SLI sometimes and somehow manages to do AFR and SFR the same time, both indicators show up and the scores go way down.
Don't mess the drivers very bad. The more you play with the drivers, the worse they get. Apply the changes in the Global Settings tab and I believe you want to run the test at the setings you use the most. So, disable the optimisations, Leave AA and AF to Application controlled, clamp the negative LOD bias, Vsync Off.
BTW - how did 06 run on your system, since you were forcing SLI 8X AA and 3dmark has some HDR scenes? nVidia don't do HDR+AA for now.
