FSB Jumpers

Ok, I'm still setting up that PC for my friend. The motherboard I have has jumpers to set the FSB, which is 1066Mhz for the CPU, however, the jumpers to set the FSB are based on 200Mhz (Default), 200-266Mhz, 266-333Mhz, and 333-400Mhz. Am I suppose to put it on the last configuration? I am confused at how the FSB is calculated, someone told me once, but I cannot remember. Thanks for the help.

    That's an MSI board? Leave the jumpers on default unless you're trying for a big overclock.
  2. FSB 1066 = 266MHz(you divide FSB by 4). What motherboard is it?

    Looking at what he wrote I'm 99.5% sure it's an MSI motherboard. And for those the jumper options are actually "auto" which is mislabeled as 200MHz, plus a few overclocks. The jumpers mod BSEL pin connections, which is why they are only auto, 200-266(200 forced to detect at 266), 266-333(266 forced to detect at 333), and 333-400(333 forced to detect at 400).

    The last time I worked with such an MSI motherboard, I found that setting the jumpers did affect bootstrap. So you don't NEED the jumpers to overclock, since you can set FSB in BIOS, but the jumpers do come in handy for keeping the Northbridge/RAM stable if you raise FSB beyond the next step.

  4. Yes, it is an MSI motherboard. I set the jumpers to the 200-266Mhz setting, but like you said u can set them in the BIOS, so the jumpers are just a hardware override option. In either case, the PC is working great. Thanks for the help.
