| Higher FSB or clock speed?
Hi guys and girls, I need some advice. When I am overclocking, should I be aiming for a high FSB speed or a high clock speed on the CPU? I can get my E8400 to 3.6Ghz with a multiplier of 9, and it will have a FSB speed of 1600, but I can drop the multiplier to get a FSB speed of 1800, but with not so high of a clock speed.
What one should I be aiming for? |

| 9 x 400=3600=3.6ghz=1600 rated FSB as Intel calls it.
8 x 450=3600=3.6ghz=1800 rated FSB as Intel calls it.
The rated FSB is your FSB x 4.
It's the same 3.6ghz.....but depending on how fast you can run your memory and how tight you can keep the timings, and how much voltage you have to apply and how much heat you can stand, one will be faster than the other.
Only by extensive benchmarking with various tests will you know for sure. |

In most instances, the bottleneck is moving data to/from the cpu. Having a higher FSB typically yields the most noticable difference.

with C2Ds/Quads , it barely makes a difference in benchmarking and none at all in apps. |
