Blizzard PPC trouble

[PiR]

Hi

I have PPC card from phase5 and I can tell you one thing:
It is always power-hungry.

The problem is not in PSU, as I have strong one, and changing it didn't change my results. The problem is that mobo was not designed for so big power consumption and voltage dropping is so big that at the end of the path, where CPUs and SIMMs are attached, it dropps the critical level, where CPU rejects to work and memory starts to forget things.

Things are getting more complicated when you realize that the power is consumption can change then chips activity change. So it may happen, that if several chips are more in the same time then the voltage dropping is bigger and CPU cannot stand it. But if they work one after another CPU can survive...

In my case I have 5,1V on '5V' line out of PSU, while I checked it sometimes dropps to 4,5V closer to expansion slot...

Good luck

Not as weird as may look like.
I remember I've read somewhere here that BPPC and BVision boards seem to work at the different temperature, as reported by several people around. This can mean that they can have different power consumption. So seems to depend more on the question if you have strong MoBo together with low power consuming PPC, than just simple MoBo problem.

Good luck
