The GE modules are rated for 40 Amps, but can safely be clocked above that. 64 Amps is the max where we feel comfortable clocking the VRMs to, and strongly advise against considering anything higher. Obviously pushing things too far reduces operational life expectancy, but if it's been included in an official firmware then be confident that we are comfortable releasing it as such.
A little bit ago on irc, hno stated that you should not go over 50A, or the stress can burn the board beyond repair, cause exploding capacitors, burned traces.
So I would want you to double check before anyone blows their unit up. While the tuning suite can go that high, it was also said it was an oversight and that it should not have been able to push the VRMs to that limit.
