Hi all:
What is the difference between a FCPGA and a FCPGA2 CPU? I have a motherboard that according to the tech support will run only FCPGA processors. I am looking at putting in a 1.1 GHz Celeron processor and the the FCPGA2 version is cheaper than the FCPGA version! Any help will be greatly appreciated.

Thanks

It's a long story. Basically, you can't use the 256k cache Celeron, only the older 128k version on your board. The previous version had a Coppermine core, the later a Tualatin core.

To complicate matters further, BOTH Doppermine AND Tualatins are comming in FCPGA2 packaging now, which is nothing more than a plated (tin?) Copper heat spreader cap over the top of the core.

If your motherboard supports 133MHz bus speed, the BEST solution is the Coppermine PIII 1000EB, which was avialable in 1.65v, 1.70v, and 1.75v versions. The newer Tualatins are 1.475v. The PIII 1000EB is about 20% faster in most applications than the Celeron 1100.

What's the frequency, Kenneth?
