I know there is no way to tell how high each individuals overclock will go, but I don't know how to get these modules to go high and not fail in Memtest. I have read that these are supposedly the best modules for Overclocking, the BH-5 chips, but I don't know how to overclock RAM correctly at a 1:1 to get the best performance. I don't know when to change the latencies, the voltages, and FSB to get the maximum overclock that I can out of these. If anyone could give me some tips on beginning to overclock RAM I would greatly appreciate it! Thanks.
