About SoftFSB
The purpose of this Windows application is to change the base clock ( FSB / Front Side Bus ) frequency without having to restart the machine. Any FSB changes are instantaneous.
Originally this software was made to see if it was possible to set FSB values which cannot be set by using the BIOS.

Warning !!
If you are a beginner, do not use this software. This software is for power users only.
If you don't know who manufactured your motherboard, or your PLL-IC model, do not use this software.
Use "SoftFSB.EXE" at your own risk.

You should change the FSB up and down one step at a time because you may damage the CPU if you don't.
(For example, if you change it from 66MHz to 133MHz in one go ... that's bad news!)
If you raise the FSB too high then it is possible that the CPU may not function correctly anymore, and the system will hang.
If your PC hangs and you can't restart it, power off. Wait a little while and turn it on again, after making sure that no damage has been done to any of your PC components. Also, if it does not return to how it was normally, you must clear your CMOS
"Does SoftFSB support my M/B or PC ?" I hear you ask; the answer is "I don't know !!".
Don't send me e-mails regarding this question.

Visually check the PLL-IC type on your motherboard. If the PLL-IC that you found is listed in SoftFSB then try it!

If you ask me "Does SoftFSB support my PLL-IC ?", don't forget to include the following information:


It is possible to make the PLL-IC data file with yourself, even if in SoftFSB this is an unsupported PLL-IC. Please try to make the PLL-IC data file yourself and see the datasheet of PLL-IC first of all.

Supported Operating Systems
SoftFSB runs under Windows 95/98 and Windows NT 4.0/5.0 in both Japanese and English language versions

It will probably run with the following chipsets ...

SoftFSB will run on any motherboards referred to on my Official HomePage.
* The PLL-IC chipset used may differ with differents revisions of the motherboard. If it won't run with your revision, chipset etc, sorry :-)
* The AOpen motherboards are different and can not retrieve information on the current FSB.
If you are using the M/B (temperature) sensor software, maybe ... you can't use SoftFSB.
Mr. t_knz "MAX1617 monitor software 1617mon" and Mr.PENTIUM 666MHz "LM75/LM78 STATUS for Windows WLMSTAT" are already supporting a synchronous control. You can use it at the same time as SoftFSB.

If you are using WaterFall Pro ... You can use SmartBus Control Module. and add SoftFSB.ini, but "this operation is unguaranteed"


Operations


Supported PLL-ICs
At present the following PLL-ICs have been tested with SoftFSB.... However, there is no guarantee that any of these will work with your motherboard.

Winbond W83977TF-xx ... These are not Clock Generators(PLL-ICs).

They are Super I/O Controller. Do not mistake them for PLL-ICs !!

Also, many old motherboards and PLL-ICs cannot have their settings altered by software.
