what CPU and motherboard do you have? Technically you can overclock them to around 1800 on the default voltage..... but wont make any real world difference unless you have a crazy overclocked computer - which sounds like you do not. RAM is not a bottleneck
I am trying to overclock my CPU to 4.0 - 4.4 GHz, however, this is a synchronous motherboard which means if I increase the base clock for CPU, it will also increase the memory speed. And I don't want to mess with the default multipliers (22x for CPU and 10x for memory).
Right now I am thinking of increasing my base clock from 133.3 MHz to 200 MHz, doing so will overclock my CPU to 4.4 GHz and also overclock the memory to 2000 MHz.
I'm not sure how the voltages and memory timing should be handled, but what I want to know at this moment is, will it technically work to overclock a DDR3 1600 to 2000 MHz? Thanks for any input.
