Hi, how does one set and check the FSB speed? I can't find any motherboard diagram indicating jumpers nor settings nor BIOS setup (in Acer manuals) for this.
I understand P4 can go to 800Mhz and Celeron to 400MHz.
CPU-Z version 1.34.1. says I have the following:

Maybe it's already running at 400Mhz but why is

shown?
Any help appreciated!

Hi Gerry,
The understanding of how this works will require some study on your part. This is because you would not have enough basic knowledge to understand any short answers, that someone might give.
Here are some resources for you to read so you will understand this subject.

I hope you will find the answers you are looking for here.
Good luck.

Thanks - http://www.directron.com/fsbguide.html is a definite must read!
A short answer would be fine but glad for that info. - I have a reasonable knowledge but was looking for some reassurance I guess. I'm assuming now it's running at 400 (100x4) but in the past I was used to m/board jumpers - this seems newer (no such jumpers - only BIOS).
cheers kleeper, Gerry.
