I own a Dell Precision Workstation 340.  It was originally purchased with Pentium 4 1.8ghz CPU (x86 Family 15 Model 1 Stepping 2) w/400Mhz FSB.

 

I would like to upgrade the CPU to a faster version.

 

What specification do I need to look for when I purchase a CPU?

 

For example Socket type, etc.

 

I have no idea how to find out what my mother board supports

 

Thanks,

 

Enzo
