my i7 came at 4GHz and my ram was at like 1550 mhz. Multiplier was 21x and the frequency was 192. now i underclockd it to 3.8GHz and lowered voltage, for temperatures. and now my ram is at like a really slow speed. not close enouigh to 1660 mhz for my liking. i was wondering, how can I make my RAM nearer 1660mhz but keep my cpu frequecny the same? the QPI link is at 181 mhz now can someone help?
