The PCCHIPS m598 SIS530 I had ran rock solid at 133mhz FSB but it’s performance was similar to a decent “100mhz” FSB board (didn’t try an extreme overclock of the k62 I had in there)

The sis540 I had was sold New, no returns and would lock up after about 10 minutes no matter what cpu, memory, FSB I chose.

At 133mhz FSB it didn’t crash any faster than at 60mhz FSB, board looked new and could never ID what was wrong.

For me the fastest was Freeway FW-5VGF+/Ultra with 2megs of cashe… sadly without ISA… i run there k6-III+ 550 acr

that board looks really cool. Unfortunately I can’t find any online 🙁
