RAM question

[Yoggumz]

i currently have this ram:

GeIL 2GB (2x1GB) PC2-6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit

i havent touched the voltages so its running at stock which i believe is 1.9v

on each module it has 2.1v on them so im assuming that that is the recommended voltages that you should set for each module.

i have never tried to adjust voltages before so could some1 please direct me on how to do it and isit really worth it.

thanks

i have a gigabyte p35-ds3l

i think ive found one setting to change. to do with the DDR2 voltage so i put that to +0.3

is there another one i need to up ie the mch one?
