IDK why people up their voltage and latency.
They up the voltage for better stability and the latency so that they can reach higher clock speeds.
p.s. if i OC my FSB, do I have to put my ratio to 1:1 on ram and/or OC my ram too?
I'd rather just up the fsb.
Depends on your mobo, I'd say you will most likely be able to keep your RAM at a set speed if you want to.
