In reply to Comment 7 (SWAUG):
removed regulater on bvision powered it direct by 3.3 volts..also have a socket on the card to change osc..it has been changed on my card from 14.3mhz to 15.2mhz..amigod reports improved performance..

NOTE: doing the above will reduce load on 5v rail keep machine more stable..overclock better..reduce heat..

I THINK THE BVISION IS A 3.3V CARD ONLY AS I CAN ONLY FIND 5V WHERE THE REGULATER did sit..


3.3 volts comes from the big connect on power supply..

my ram chips 256MB ( memory ) has akasa heatsinks..both sides..

BVISION has thermaltake heatsink on ram chips..

most of BLIZZPPC has heatsink ( including the AMD flash chip )

all chips on BVISION has heatsink..


ALL heatsink are earth out including ram heatsinks..


i can controll voltage on both processors 3.3v,5v rail,12v rail..

i can also say that the blizppc does not like voltage below 4,8 but also not above 5.18..my machine mis-behaves above 5.18..

a1200ppc desktop..

just to add you do not need such a big fan..


on my machine i got a 30mmx30mmx10mm heatsink with a built-in fan..( fan is replaceble )..


made a cut in phase 5 heatsink 30mmx30mm put heatsink in place with ARTIC SILVER GLUE ..will still fit in a1200 desktop case..i NOW have a heatsink with direct contact with ppc chip ( with built-in fan..


if fan fails it just operates as a normal phase 5 heatsink..but you can change the fan..


the whole unit is just about 3-4mm bigger than phase 5 fan..it works FANTASTIC..


i have done lots more mods..
