450Mhz? really? 2.5Amps can't be enough for that, In sight of that I've bumped up the specs for the regulator to 60Amps total. (3Amps per chip)
With different inductors i could push it to 80Amps total. (That would be scary 100Watts per module

)
for 450Mhz you will need water cooling, but the change is very nice!
Is this for sure? I mean i even read someone took the heatsink away form an original avalon and the heatsink didnt even has contact with most of the vias there. So is it for sure that the heat is so bad that air isnt enough? I mean thats not a gpu that is very hot from the start, its a complete new tech that isnt even fully explored. So i can imagine that the designs that burnin and bkkcoins create will give some surprises maybe.
