Blizzard PPC + BVisionPPC: system unstable :-(

[Karlos]

Heres how my hw is set up. First of all, power is pumped into both the original connector and the floppy port connector. Some tower setups only connect the -12VDC line through the original connector.

1) There are a couple of chips next to the PPC that can get way hot. I use a mica (non conducting ceramic) disc and heat transfer compound to ensure that theyre in good thermal contact with the heatsink.

2) An AMD K6-2 heatsink sits on the 040, but no fan due to space limitations...

3) A power amplifer heatsink (copper, 1 inch tall vanes) is attached to the Permedia with heat transfer compound.

4) A 3.5 inch case cooling fan is mounted just above the BVision/BlizzPPC assembly to ensure good airflow through the system.

Everything runs just fine...

I'm thinking of buying a proper graphic chip heatsink cooler with fan and glue that to the Permedia 2. Then I can run the chip on it's proper speed.

MELTDOWN = 110 :-D Muha ha ha ha :-)

-edit-

Or without cooling,

UNSOLDERSELF = 110 :lol:

Be very careful overclocking the Permedia...

I'm not going to overdo it though! I wan't to keep my BlizzardPPC for a long long time :-)  :-)

Then don't overclock it at all would be my advice. The card is already running as fast as it's design reasonably allows. But with decent cooling, clocking to 90MHz os ok.
To be honest, you won't notice much difference, except in 3D (you get slightly better fill rates).

I still run mine at the default 80MHz...
