I run a few systems here with a IBM/Cyrix 6x86L P200+. The Cyrix P200+, when run at 2x75 MHz is *very* fast but, with a data bus speed of 75 MHz it's very picky about which memory/cards work well. You'll want to have SDRAM at this speed and maybe avoid early Adaptec 2940 PCI controllers since they have problems at this speed. As you said, you can set the speed to 2x66 MHz which will give you good performance still, and avoid speed problems altogether. I have overclocked a CPU here at 3x60 MHz and it's very fast on computation (but i/o is not comparable to 75 MHz). The boards we use are Matsonic MS-5120 (see www.eurone.com). Don't have any experience with AMD. Regards, Alex Boisvert --- FreeBSD: Decouvrez la puissance de votre ordinateur - www.freebsd.org
