Blizzard PPC card but may apply to Cyberstorm PPC/Mk III card
**depending on settings** anything over 64Mhz can damage the card. i discovered this many years ago.
the problem has been fixed on my cards which also has a hack which allows me to have a FPU on the A1200 motherboard,without me having to remove it. so when the Blizzard PPC card is disable by holding down the 2 key the 020/FPU on the A1200 motherboard comes active
anyway cards overclocked over 64Mhz you will know if you have a problem,as you will get many lock-ups,BUT IT CAN GO WITHOUT WARNING.
one of the fault is that memory and PCI will stop working,but the 68k processor may continue to work (depending on type of card). SCSI may also stop working (i did not check this part)
so care must be taken when overclocking over 64Mhz bus.
I've had a Cyberstorm MK3 overclocked to 66.7MHz for years and it's been 100% stable. I had it modified at National Amiga (I believe they changed the oscillator and jumper)....maybe I got lucky? But the card is rock solid. I believe it's a 60MHz 060 on the card, but I forget. Heatsink gets in the way
Is there a way to tell the 060 MASK/revision in software?
