Overclock my CS MKII '060

[PaSha]

Sockets:
Some had socketed oscillators delivered from phase5, some had the oscillators soldered on. If yours is soldered directly to the board, then simply replace it with a socket.

Ram:
Use 60ns modules only!

Speed:
60 MHz definately will work, 66Mhz should also work fine. YMMV, depends on the 060 itself. With a newer mask 1G65V 60MHz 060 from gurumeditation.se or somewhere else, even higher speeds than 66 MHz may be obtained.

SCSI:
Two different versions of the Cyberscsi module exist.

One with a 'Symbios' SCSI chipset, this one does not tolerate any overclocking.

One with a 'FAS216' SCSI chipset, this one will accept overclocking with no problems.

Disclaimer:
Your mileage may vary. I am not responsible for any damage done to your hardware from doing the above mentioned actions.

EDIT:
Cyberstorm mk2 040 boards can easily be upgraded to 68060, instructions can be found on amiga-hardware.com

I have the FAS chip on mine and I can't overclock it. There must be some other reason than purely the chip type. I can't even go to 60mHz with it, even though all my SIMMS are 60ns. Check my photo album to see my setup.

Easiest way to find out is to overclock without the SCSI module attached. Also, try with different RAM, or even a different 68060. (my CS-PPC was delivered from Phase5 with a dodgy early prototype 060).

Please don´t shoot me for my easy thinking, but what if you just replace the 060 with a LC060@75Mhz How bad can this LC be  :-?

Because it's a PLCC chip? (hence it will not fit).

Anyways, the limiting factor is the slow old SIMM RAM. The CT60 Atari board happily runs a full 68060-60 chip at 100 MHz.

Bum luck with your cyberscsi....
