Is any extension able to change the Front Side Bus (FSB) speed? which? how?
« on: February 20, 2011, 08:53:03 AM »
Hello,
by installing a new processor AMD-K6 III+ ATZ 400 (running now at 5,5x100MhZ) on my board K6XV3+/66 (more speed), I was thinking about increasing the FSB speed (>100MHz).
Is there any extension which could do it?
On Win98 side, CPUCool seems to do it; but there is no linux version of it (and I prefer not to start a WINE emulation of CPUCool for not corrupting my machine).
Any idea/proposal is welcome.
Thanks.

A possibility to change FSB may be chipset specific and depend on BIOS.
e.g. IIRC there is such an option for some eee models.

FSB setiings and all cpu and cpu clock-related settings are made in the systems BIOS
As far as I know FSB can not be via apps nor via OS

The BIOS is software, If it can change it so can a program. Whichever registers or ports need to be
written are most likely privileged meaning the app would have to be run as root or possibly loaded
as a kernel module.
