Need Help!! Dell XPS M1730.....SLI doesn't work at all, CPU usage always stays at 100%...b-_-

Hey guys,
I just purchsed Dell XPS M1730 with
Windiow Vista ultimate 32-bit.
T7700 2.4 G CPU
8700 SLI
4G RAM

It works alright with disabled SLI
and when the SLI is enabled, all the games becom extremly lag.......and CPU usage goes up to 100%....and then freeze.....and then reset.......b-_-
I upgrade the Driver to 169.04.....seems work better for NFS Carbon, but not other games....
i saw heaps people discuss about this.....anyone got some suggestions?
By the way, does SLI work perfectly if i downgrade to XP ??

And i don't know if it is normal for my CPU varying form 20%-100%, even i doin nothing......is tht just because the VISTA??

Thank you guys~

 

Driver version 169.09 worked fine for me under Vista with SLI. I didn't try the version you have.

You might want to try booting to safe mode, removing the display adapters and uninstalling the nVidia drivers. Reboot and install a later driver.

I have since wiped my laptop and installed XP. SLI works fine, with the caveat that every time I try to reboot Windows, it fails to load. Booting after power-on works fine. If I turn SLI off, rebooting works fine. This happens in driver version 169.09, 169.13 and 169.17.

It's probably something stupid that I've overlooked, but after reinstalling XP 6 times over the weekend, I'll just live with the problem for now.

 

D.D. how did you install the driver?

The best way that I've found to get the drivers to work for SLI is to install it.
It will come up with the message about your 8700 card click okay.
When the 2nd card message comes up click no.
Reboot your machine.
Go to My computer and bring up properties, then device manager. One of the GFX cards will have a red X on it. Click update driver then install from where you unzipped the driver.

That has worked 100% for me. There are a few threads on it. But the general gist of the information is when the 2nd card comes up you click no. Then you manually update the 2nd card after reboot.

I can't help with the CPU part. I have Vista but I mostly stick to XP. It could be a process or 2 that is eating it up.

Sorry I couldn't be more helpful.
