GregTech CEu Version

v2.8.10

Your Solution

Machines can't overclock past MAX voltage, even though most of the code that could support it (such as using longs for power) is already in place. Base CEu wouldn't use it for anything currently, but it adds room for future expansion and for pack and addon devs

It should be simple enough to implement by adding an array of every voltage until max long and using it for getNumberOfOCs() and getOverclockForTier(), and making machines display the voltage as "MAX+" or perhaps "MAX+1", "MAX+2", etc
