I'm sorry I ask this but I am a little new on overclocking. I have an x3440 and a asus p7h55-m lx as my motherboard. I can overclock but then when I put my bclk at around 180 with a multiplier of 19 my computer crashes because the memory overclocks itself, I tried lowering the cas latency and messing with the dram settings but I am new and nothing I do seems to lower my RAM speeds so what can I do to lower my RAM speeds? Thank you in advance

Is there any way I can make just the processor clock get higher? Not the memory clock
