I'm running 80MHz with a CSMK3, Rev 6 '060 & Crucial 50ns 32Mb EDO SIMMS. I changed a jumper and added a 2nd oscillator so the SCSI and bus speed are not overclocked. The EDO memory isn't any faster in the MK3 but 50ns non EDO memory is hard to find and high quality EDO memory works fine contrary to some rumors. Memory speed does increase dramatically as the CPU is overclocked up until the memory can't take it anymore. I may be able to do 90MHz if I had an oscillator but some 60ns SIMMs were having a problem already at 80MHz. The Rev 6 '060 does run very cool even at 80MHz. It runs cooler than any '040 (even at 25MHz) I've seen.
