WHATS GOING ON?-2 x Nvdia 6600GT's

Okay I've had my Mesh for af ew weeks now and upon further investigation, myDxdiag, Display Properties (77.77 drivers) and 3d Mark are only showing one card! :shocked2:

Funny thing is Msinfo shows 2 and device manager shows 2. So the hardware is there but the software is not recognising them. I have alos enabled the SLI mode in the nvidia display properties, which was not activated when I receieved my PC

When playing games am I only using the one card? or is it too technical for my limited knowledge?

Please help

Run some benchmarks and see. Try 3dmark05. With 2 cards, you should get about 6000 plus and if you are only using one, you'll get about 3000-3500.

You're using both cards - dont worry. You cannot enable SLI in the driver unless two matched bios cards are present. This, of course, only applies when you are playing a game that has an SLI profile.
