View Full Version : Whic is better Higher Multiplier's or FSB
Ok, I need help. Let me start out with I have read most all of the strings here and other places. This is my first REAL O/C, I have played with the FSB on my K7Pro.
I should receive my KK266 along with Tbird 750 FOP 38 And a cardex geforce2 mx ( will order better ram in couple o weeks ) I now have pc100.
Now the question is, which will be the best in performance higher multiplier or higher FSB? I understand 800mhrz is 800 mhrz but it seams the highr FSB would be better performance is this true? I wan't to over clock as much as AIR cooling will allow but I also want best performance and stability. ;-) :-)
the best way to oc is to push both the multiplier and the fsb but make sure that you have adequate cooling ;D
Sorry about the other posting a little lower on the page I messed up I didn't think the outher one posted.
Thanks for the input so far

When you raise the multiplier your overclocking the CPU. When you raise the FSB your overclocking the CPU and other stuff -- including your RAM and system bus. The system bus by default is 33MHz. Up to 120MHz FSB the system bus is 1/3 the FSB. So at 100MHz FSB the system bus is 33MHz -- this is spec. When you raise the FSB to 110MHZ (for example) you overclock the system bus to 36.7MHz. Overclocking the system bus too much can lead to harddrive errors.
When you reach 133MHz the divider increases to 1/4, so the system bus is back to spec -- 33MHz. On some systems -- I don't know if on all -- the divider will increase to 1/4 at 120MHz FSB, where the system bus is actually underclocked at 30MHz.
Find a CPU speed your machine performs well at and is reasonably cool. The see how to get there with a combination of multiplier and FSB overclock, without overdoing the latter. As I said too big a FSB overclock (giving too high a system bus) can give harddisk problems.
You'll see in my sig I'm at about 900MHz, but 8x113 instead of 9x100.

I say a decent amount of both, however, watch those PCI bus speeds, as HDD's are notorious for screwing your data to hell over 40 or so Mhz.
