DMOS has another sweet article for us over at DevHardware/OCAddiction. This time he explores the world of OC’ing with his P4 800FSB.
[color=grey”>"With air or normal water cooling, heat is going to likely be the limiting factor in your overclock. Even if you had a 3.2GHz CPU to start with, you are likely going to be limited to the same 3.6GHz that a 2.4C can potentially get to. Now, when at equal clock speeds, the processor with the higher FSB will be the better performer, when you look at applications that involve more than just the CPU (ie most real apps). This is because there is more transactions with the memory, and therefore more theoretical bandwidth available. For example, lets think of that potential 3.6 GHz on both a 2.4 and 3.0 CPU. With the 12x multiplier of the 2.4C, that equates to 300MHz for the FSB at 3.6GHz. By comparison, the 3.0 is only turning 240MHz. I’m not going to get into memory selection right here (read below), but lets just leave it at the fact that the 2.4C, even with use of the 5:4 memory divider, will perform better than the 3.0 with 1:1 in most cases.
