Have a spare 60mhz crystal here which I'm thinking of replacing my 50mhz one on my Cyberstorm MKII '060 card.
Has anyone here done this? just wondering so i don't have to go thru a resolder and put back the 50mhz crystal
Going to use a heatsink with heat adhesive tape and a 12v fan on top of it from an old 486 chip

I would have if it wasn't for my harddrive dying :-( Are you sure you need to solder? Aren't the oscillator socketed? They have been on all those I have seen so far.

Maybe it is..that would be very nice..might get a 66mhz one and try then :-)
Not sure if I need 60ns simm's when I overclock? have a mix of 70ns and 60ns now on the board

Is it a a SCSI drive connected to the Cyberscsi module?

Yep. I haven't given up on the drive completely yet though, but it definately needs to be replaced sometime soon, the sooner the better.

50pin SCSI drives are dirt cheap..just wish they could be bigger..seems like 4.3gig was the biggest size back then
But an 50pin-->68pin adapter solves that problem :-D

Amigaz : I had my CS MK2 060 overclocked by Lord Spider who uses a speedmaker module to find out the best speed. Seemed that 66 Mhz didn´t work, probably because of the scsi module connected. But 64 Mhz works just fine :-) Maybe yours runs faster as every card is different ...

Was your crystal socketed?

Good question, don´t remember anymore as one of my best friends has now got the card :lol:

Depends on which Cyberstorm you have. MarkII boards had the oscillator in a socket; MarkIII board were soldered (though second hand boards may have been modified by a previous owner to include a socket).

@ Amigaz
Mine is socketed. I think most of them are. I overclocked mine to 60mHz. All my SIMMS are 60ns. However my board won't tolerate 66mHz. In both cases (60mHz and 66mHz) the SCSI cannot be used (at least not with my combination).
-
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.

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

Nice, that's the one I have :-) Hopefully the 060 CPU won't give me any problems either. Have a spare 060EC66, so I might have to live without FPU.

arghh...have the Symbies chip here...means I have to stick with 50mhz then :cry:

@ PaSha
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 ??? :-?
-
@ PaSha
The original tests that I conducted gave me perfect performance at 60mHz without the SCSI module. As soon as I attach it, however, I cannot have 60mHz without crashes.
Maybe it is that combination of 060 and SCSI?

Overlooked this one...
Correct, 50 pins SCSI drives are dirt cheap, but the problem is that I want to install a 18 GB as a minimum, and preferably a 15k RPM one. I already have some 50 -->68 pin converters, but if I use these I will have to remove the CD drive. I wish there were a bit more room in the A4000D :-)

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.
@X-ray:
Bum luck with your cyberscsi....
