Core 2 Duo E6550 @ 2.33GHz is the processor. 2 drives are mirrored. Motherboard is P5N-T Deluxe I dunno where to look up settings.

I am fairly sure my video drivers are up to date and will check on the chipset driver update.

I didn't think DFO supported SLI. I generally have settings on "let application determine" setup.

If you think the ram would help I can drop another 4 gig in.
