I think the best thing to do is put the card back to its original state.
That means the 68040 should be put back to 25 MHz again. The PowerPC is likely a 160 Mhz one so it should be put at that speed. It was clocked that way because you have 2 oscillators. If you had 1 it would be clocked at 175 Mhz.
Overclocking a 68040 is pointless. Just get the cash and send it to the Amiga Center in France and get a 68060 on it.
The possibilities I see is that either the oscillator that is driving the 68040 is dead or there is break in the signal line or the 68040 is dead.
If you don't want to send it of to get it fixed I am willing to buy if from you but ofcourse for a defect price because in the mean time the thing might actually be dead.
On a note:
There were different versions of the BlizzardPPC and especially the first versions had timing problems. These were later fixed. I had a BlizzardPPC once that didn't like a motherboard at all too.
Later on Phase 5 sold 160 Mhz PowerPC versions with 1 oscillator which made the PowerPC run at 175 Mhz and these cards can take any motherboard.
On a second note:
75% of Amigans should get there hands of these expensive pieces of hardware. I have seen 6 BlizzardPPC's so far and of these 3 had missing components like capacitors broken of where they should have been. I even saw this on a BVisionPPC!!
I have managed to replace all those broken of components and I'm really gutted to see how some people seem to handle these things.
Please, please, please if you don't intend to fix these cards, send them to me. For free! :-D
