Front Side Bus

[Magnum]

My motherboard doesn't allow any adjustments to the Front Side Bus or CPU multiplier.

I am curious if anyone has those capabilities.

I have an old Gigabyte one that does, not so sure about newer ones.
It's usually via jumpers on the motherboard itself.

Depends on the board, and how it is sold.

Typically you can configure these via CMOS/BIOS or jumpers.

Boards sold to OEMs (think Gateway, Dell, etc) often have options disabled to the system runs as delivered, and you can't tinker endlessly with the settings.

Memory sticks have EEPROMs on them indicating preferred timing parameters.

Andy,

Its usually boards aimed at gamers that have this capacity, CPU and bus overclocking but its dicey unless you have very good temperature diagnostics. The only computer I own that is overclocked is an antique Celeron that I have tweaked from 1200 to a bit over 1300.

The CPU itself may be locked, lots of Intel chips can't be overclocked.

I think for the processors that are locked only the multiplier is locked, so they can still be overclocked by increasing the FSB frequency, if the board supports this.

I'm limited here too because a bad choice of onboard motherboard.
Have see some dual cores reaching 2.8ghz easily, but when I try, my computer freezes, the best that I can get in it is 2.2ghz. The default is 1.8ghz.
When I change de multiplier/fsb..., the system don't recognize sata hd, usb, ... .The only time that it worked, I have lost of data.  My first approach is change the power suply, but after many tests, now I have sure that is my motherboard. Second approach was update bios, but nothing have changed.
In another computer, with offboard motherboard, I can control all, vcore,vfan,... .
