Phase5 CyberStorm MK2 @ 100Mhz (040 Hack - Stable)

Phase5 CyberStorm MK2 060 @ 100Mhz (040 Hack – Stabile)

Questo e’ un semplice hack per eseguire l’overclock sulla Cyberstorm MK2 a 100Mhz senza bisogno di adattatori o semplicemente sostituendo l’oscillatore che causa instabilita’ e malfunzionamenti.

L’hack consiste di downgradare la Cyberstorm MK2 a 040 semplicemente spostando le due resistenze che vedete contrassegnate nelle foto.

Per alcuni modelli di CPU o di MK2 e’ consigliabile anche sostituire il regolatore di tensione originale LT1085CM da 3.3v con LT912CM da 3.5v ma se l’amiga risulta stabile dopo ore di funzionamento si puo’ anche evitare la sostituzione del regolare di tensione.

    Hi,

    I have one MKII 060/50 ver. 5 + SCSI II module. After overclocking SCSI will be working or not?
    What version of 060 I need, version 5 is good or? And what about temparature CPU after overcloking?

    Thanks for answer.

    Regards,

    Joe

    You need REV 6 (71E41J) , about the temperature you need a heat sink and fan. SCSI module works.

    Hi,

    so If I upgrade to REV 6 and then overclok to 100 MHz, SCSI will be working fine too?
    As I read there are two SCSI chips and only FAS16 support overclocking and secon Simbios not. I have first one.

    Thanks for answer.

    Regards,

    JOE

    I’ve done the 100Mhz hack for several months, but I am getting SCSI write errors (and sometimes read errors). The system will appear to be fine but if you try to copy a large amount of files you can get a write error. Also HDToolbox will occasionally lock up.

    I have a Rev 6 060 with heatsink and fan…so I am wondering if this overclock is 100% stable with the cybscsi.device ….

    Ok, so I un-did the 100Mhz hack and I was still getting the weird write/read errors, so I guess this is not related to the overclock. Only certain devices would cause errors, others would work, which is very strange. But anyway I found a combination that works…so now the question is, do I go back to the 100MHz hack? I don’t like soldering those tiny jumpers, plus one of the pads is not in good shape.
