What a bump, but I guess I'll answer this rather misunderstood problem.

It isn't just about your power input. Yes, upgrading from 15 to 16 overclockers in a rotary macerator and other advanced machines take massive amount of power, but the main thing making it difficult to upgrade is that if it runs out of power at any time, it'll either reset or stop working.

You need energy upgrades so your machines can actually store enough power to accomodate another overclocker and power up to its new max rate without running out of power first. And power requirements increase exponentially. If your machine doesn't have enough energy upgrades in them, don't even think about adding more overclockers. Haven't taken numbers, but refer to tier 1 unupgraded machines and how their power requirement increasing rate is 1.6^x, x being number of overclockers. It's likely something similar to that on upgraded machines.

Of course, once the machine finishes maxing out on speed, it would then only require 1 EU/t to maintain that constant speed. And that's what levers are for.
