I have oc'ing the CPU and messing about with the Vcore down to where I want it. I now want to turn to RAM timings and OC'ing it a notch. With GeIL 4GB (2x2GB) PC2-6400C4 800Mhz, what am I looking at for timings? Baring in mind I haven't touched the Vdimm yet. What volts should be ok for a slight overclock?
