Here's the ram...http://www.directdial.com/RM12864AA667.html

in my bios the minimum manual voltage was 1.8.. the next step was 1.85 it didn't seem to want to change on smaller increments... on 1.85 it said over clocking failed.. returning to default setup..

I'm a little unclear on the latency.. by default it's 5-5-5-15 but I assume if it's CL4 should it be 4-4-4-12?
