I have a DC kit of OCZ memory 2x512mb, currently set at 2.5,2,2,7. I can change the voltage from 1.6 ~ 1.8. My question is will there be a change in performance if I increase the voltage? Also, do you think I can get lower timings, say 2,2,2,5 if I increase the voltage and maintain stability? Currently at 1.6, if I lower the timings my computer wont post. Thanks for any help.
