Hello guys,

I'm wondering why is my PC6400 RAM only operating at 400MHz? I just overclocked my Pentium Dual-Core E2180 to 2.66GHz, and when I checked the operating frequency of my RAM it's 400MHz (its actually 399MHz, close enough) in CPU-Z.

Another forum has been telling me to put the ratio to 1:1. Will that overclock my RAM, and please give me a very good explanation to that, if yes or no.

Please tell me why my RAM is displayed at 400MHz?!
