this is what happens to a blizzard ppc when overclocked and mem settings set to no precharge and no cooling is added. you will get a sudden crash and you find memory and bvision has stopped working. cyberstorm has the same type of chip onboard (cypress)which can run as high as 58c (if i remember correctly) without any overclocking.

there also a chip marked MACH near the Bvision socket which is a little better which seems to run around 52-54c.

due to lack of parts it`s not always possible to repair every card. here my Blizzard PPC memory & bvision stop working i then found the fault to be a cracked solder joint somewhere on the card. i say somewhere as it hard to see cracked solder joints.

i don`t know about the cyberstorm but you don`t have to disable the PPC processor on a Blizzard PPC.

it either works or it does not.

here i can remove the ppc processor(project 5)and the card seems to work fine without a PPC processor memory still shows up on workbench.

when memory stops showing up it`s a **serious fault**,it will effect Bvision/PPC processor and possibly the SCSI. the 68k processor will work fine without all three working.

but it`s hard to say if cyberstorm suffers from the same problem as a Blizzard card when memory stops working.


for the Blizzard PPC card if all four chips are cooled,if it starts to overheat it will give warning signs(crash or lock-up) even when overclocking. if you overclocked and you dont have right cooling see above post.

I always thought they crippled the speed of their 040/060 cpus on purpose to make the PPC seem more faster than an 060 than it really is.  Many people were fooled.




from my point of view i think it was a heat issue,if the card ran any faster you are going to run into problems. i can`t understand why their release a card without some kind of cooler with chips that ran so hot it can burn your finger. perhaps the card should have come with somekind of hazzard.

most componets that run at high temperture has some kind of cooling device.

with the right cooling iv yet to do permanent damage to a Blizzard PPC no matter how far i try to overclock it.

perhaps adding more cooler cost of card would be more.

cyberstorm are in towers,so has more airflow,but what about change in normal air temperture summer months this also appiles to the Blizzard PPC card.

IMHO he has stolen you 140Euros. If he couldn't repair the ram he should have warned you, and he should have charged you just 50Euros. You are not responsible of his lack of skills repairing hardware.

IMHO next time you'd better send it to Castellen (at least he's honest).



remember he had to change the CPU to get the card to half work in-order to find the remaining fault(s). it takes time tracking down fault(s),and there are other customer also awaiting repairs.  

dont forget the board has some new parts which may not be wise to remove and pass onto other customers.


this is a question someone should ask ACUBE as if their only change/upgrade faulty PPC chips on PPC card,what happens if the CPU is changed and the card is still faulty.

how will your card be returned and what is the cost. will it have a new CPU still attatched?
