Heres what I have got at the moment
Pentium 4 2.6GHz 800FSB HT
512 DDR PC2700 SO-DIMM
So as you can see I am running a laptop and would like to upgrade the memory as I believe this would give the best performance boost.
When using CPUZ I notice that my memory FSB is 200, which I believe is correct ( 200 x 4 = 800 FSB ) so in theory would my bandwidth be the same if i was to get PC2100 or would I notice a decrease in performance?
