52a is max for the vrm before OCP kicks in n kills the vrm...so with that limitation you don't have much oc'in room...i'd say you'll be lucky to get 550mhz if that outta these units unless you super cool the vrms lmao...but that wouldn't be worth it
What is OCP? (please excuse my ignorance)
How super cool are we talking? Pretty sure the Novec would still keep them at 65 if you were running 100A through them/
EDIT:
Over Current Protection right?
yes, someone in picture your mining rigs already put a neppy in novac stuff and the vrms were cool 50c but he said if he tried to push the vrms past 52a they would shut off...hmmm maybe its unique to each vrm and you just have to play around with setting i guess...idk i don't have one to play with...ahh so maybe you can oc more then...dunno but good luck
