Is SLI enabled?

[cntrlaltdel]

I recently reloaded my rig with Vista Home Premium, noted new nVidia drv's and so used them as well. I noted that both cards are listed in device manager and are working. Bridge is in place across them. However, in nVidia Control Panel, under 3D settings, there's no enable/disable SLI heading as I'm accustomed to seeing. Makes me wonder if I'm in SLI mode or not?

Thoughts?

It's not enabled if you aren't seeing the CP setting. Can you give us more system specs?

Make sure your board doesn't require any BIOS options, weird flipping of chip cards, or jumper settings to enable SLI.

Well both cards are GeForce 7950 GT's on an ASUS P5Q Delux MB. They were both working fine (I think) and had been in the system for over a year. Recently, I started getting random lockups that got so bad, I couldn't even boot in safe mode. Decided to reload Vista, switching from 64 bit to 32 (tired of looking for drivers that weren't written yet for certain apps I've got). Now I notice the lack of the SLI config page. I really hadn't looked at it since install way back when, so I don't really know exactly when it may have changed for sure. I've pulled and reinstalled the cards to be sure they're seated rite.

Asus P5Q Delux
8 GB Mem OCZ Platinum
Intel Quad Core Q9300 Yorkfield 2.5 GHz
Thermaltake Purepower 600 W
eVGA GeForce 7800 GT 256MB X 2

BTW, I've still got the lockups, altho not nearly as frequent. Seems to occur when I'm messing around with config files or driver files as in device manager. (sic)

Here's your problem: ASUS P5Q Deluxe this board doesn't support SLI.

Well, there you go. Amateurs are so unpredicatable...........and so, often dangerous!

Thanks Megaworks. Looks like it's time for a Xfire setup.......
