I have and old Pentium II tower that I use as a file server on my home network. The problem is that although all three RAM chips in it are labeled as 133 MHz, the computer is using them as 100 MHz chips. There is no setting for this in the BIOS, so I'm trying to find out if there is a jumper setting to select 133 MHz. It is a home-built system that my cousin and I built out of spare parts, but according to AIDA32, the "motherboard name" is "Intel Seattle II SE440BX-2".

I have been unable to find any information on this motherboard myself, and I am hoping someone can help out. If you can't, don't worry; it's not a real big problem. I just think that I *might* get a little better system performance at the correct clock speed.

I found the MB spec. http://www.motherboards.org/mobot/motherboards_d/Intel/SE440BX-2%2BSeattle%2B2/
You can see the MB has Front Side Bus (FSB) speed 100/66Mhz, that means the RAM can run at 100mhz or 66mhz. Because in older systems, the front-side bus (FSB) was directly tied to the cpu and northbridge (memory controller hub). So your 133mhz ram will run 100mhz only. In the newer system, this story will be different.
For more info you can read this " Front-side bus" http://en.wikipedia.org/wiki/Front-side_bus

Thank you cin19; it wasn't the answer I was hoping for, but it is the one I needed.
