I just upgraded my dell 5100 from 256 to 512. It had pc2100 in before that ran a 1:1 ratio. The new ram was basically free and is pc2700 out of a dead 5150. Now cpu-z tells me that its running at 166mgz on a 4:5 ratio! The worst problem is that its a dell and has zero bios options for changing that sort of thing. Now who thinks it would be faster to run 4:5 with more bandwidth or 1:1 with less bandwidth. I'm leaning toward 1:1 being faster, anyone have a tool to set it to 1:1 in windows?
