133FSB P3 on a 100FSB Mobo

[stevesnobo]

Hi,

I have a compaq socket 370 FC-PGA supporting a 100 mhz front side bus, which I want to upgrade to a PIII from celeron. Nearly all the used socket 370 FC-PGA pentium 3's on ebay (the only place I know to get them) are designated for a 133 mhz front side bus. Can I run these chips on a slower, 100 mhz bus?

thanks

You can, but because they have locked clock multiplier (with the exception of engineering samples), the processors will run at slower speed. For example, Pentium III 800 (133 x 6) will run at 600 MHz (100 MHz x .

The faster pentium 3 with a 100 Mhz bus I know, is the 1'1 Ghz version (11x100), but it usually has bottlenecks.
