I currently have 4g of DDR2 800 SLi memory for OCZ. The voltages it says to run are 2.1. I have a 680i board, and it has it set at 1.85. SHOULD i reset it at the indicated 2.1? Or is the mobo auto setting it at optimum levels? Any help would be appreciated. Everything is running fine though, but really haven't stressed this newer system yet.
