I think my 745 is a decent chip also.I am just trying to decide if I want to go over 1.3 (1.34) 24/7


or under 1.3 (1.28)



Or if 1.4+ is safe for 24/7 which I would guess is needed for 4.2+. I can do 4.2 1hr of occt at 1.34 but will get a random crash. I haven't had my voltage any higher than 1.344 yet and dont plan to for a couple months to see how the chips hold up with the higher voltages.
