modifying a mainboard

[Heb]

just an idea i had... if say you have a mainboard that has a max fsb of 75.... what would happen if you modified the clock circuity (using clock doublers dividers ect ect) to say make it 83 90 ect ect...

would you be able to manipulate speed, or would the system just not post, or what?

You would likely overload the chipset as it probley wasn't designed to handle higher fsb speeds. In lamans terms... you fry your board http://sysopt.earthweb.com/forum/wink.gif

not necessarily!

take for instance an early BX board. They had no FSB setting other than 66 and 100. but we all know it could go up to 150MHz. So get a new clock generator an voila... (not that simple but theoretically true and can be done!)

Same holds for most other chipsets. They are all designed to work in a range of speeds but not all mobos take advantage of that. So as long as you know how far you take it, and you have the technical experience to do it, and find a means of controling the fsb (you can't be sure it will work at say 83Mhz so that to just fix the clock to 83 once and for all, can you?), yes it can be done.
