Srry. I hit enter. Um ya theres major jerkiness and lag when I play CSS. I have 4 256mb stiks of RAM at 2.85v( no change at stock volt), 3200+ on a Hyper 48, and a Gigabyte K8nxp-SLI. This began happening about 6 months ago, and I'm thinking that the RAM is bad. Is it? Or do I need to buy a new NorthBridge cooler?
