Overclock maxs

hi all;

ok im trying to get the lowering of the multiplyer theory stright. My question is how come you can get higher cpu speeds by running at a higher fsb and a lower mult. For example some people say that they cant hit 1881 mhz on an xp 1600 by having 9.5*198 setting how come you cant do that with having it at 179*10.5 for example? i know that you are supposed to up the fsb to get better overall preformance but im just trying to see how high i can keep the mult if i have a 166fsb because my network card doesnt seem to support any setting higher that 33.

Sounds like you answered your own question.
A higher memory bus setting allows more memory bandwidth.

(bus speed) x 8-bytes(or 64-bits) = memory bandwidth.

Higher the bus speed, the more memory bandwidth.

Your gonna want to lower your multiplier and run the next FSB setting which allows the next divisor to kick in, to keep your NIC in PCI spec at 33 MHz. I'm not sure what chipset you have, but if it supports a 1/6 divisor, that next FSB setting will be > 166 MHz (166 / 6 = 27 MHz).

BTW: Quote: "For example some people say that they cant hit 1881 mhz on an xp 1600 by having 9.5*198 setting how come you cant do that with having it at 179*10.5 for example?"

Answer: They can. Your processor simply runs at a multiple of the FSB. They could theoretically run their CPU at 1881 MHz, with settings at (376 MHz x 5). The only thing stopping them is currently a frequency of 376 MHz on the FSB is unobtainable.

i can't

I can run 1900MHZ at either 10x190, 10.5x181 and 9.5x200.

Max CPU speed is exatly what it is, max CPU Speed. You can't make a cpu run faster a lot faster by increasing or lowering your FSB. Maybe 10mhz faster but not 100mhz difference. Increasing FSB just makes the whole system run faster.
