Hi ppl,
I had a problem with this cards (Nvidia Geforce 8700m GT x 2 -256mb), just like soooo many around the web:
SLI didnt work properly. But I think i figure out the problem.
I installed some drivers, 167.51 and 174.82 To test it out, but SLI was just not working.,
the performance was just ridiculous. So after research and almost getting crazy... i did this.....,:)
1. Disable AgeiaPhysx Card. (go to Device Manager, just disable, you dont have to uninstall)
2. Install drivers. (167.51 or 174.82 I recommend)
3. Restart Machine
4. Enable SLI (Nvidia control panel)... and Restart again.
5. SLI SHOULD BE WORKING GREAT! AFTER THAT.
6. If you see that performance is what you expected , then you can Enable AgeiaPhysx again. (and test SLI again).
8. Should be just fine by now. (SLI + Ageiaphysx).
9. Im getting 55 fps - 60 fps. at the beggining of 3dmark06 test. Without SLI enabled, you get 25 - 28 fps.
10. If SLI, stops to work again (it shouldn't though)... but just do the same thing.. Disable AgeiaPhysx. Enable SLI. RESTART, done.
Conclusion.....
AgeiaPhysx Card must be creating some conflict, since it uses a Pci Express port... same type of port as the video cards.
Im just guessing about the conflict, due my own experimentation. But it finally fixed my problem.
So I can say now.... the Machine is great. :)
I hope this will help many, who are frustated with the performance of SLI Setups on DELL laptops M1730.
good luck to all.
Andreas
