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!
