That is a good explanation. Thanks man. But the one i didn't understand is, how many overclocker upgrade i can put before i need to put a transformer upgrade?
And with 7 overclocker / 8 overclocker on the recycler you said eu consumption will be 512 eu/t right? So i can just direclty connect it to an mfsu or do i need to put 2 transformer upgrades first?
And you didn't answer my assembling machine overclocker. Can i put some overclocker to there? Because it is very slow to assemble something together
You need one transformer upgrade for every transformation you want to make - so if you want to feed it more than 32 eu/t you need one, and if you want to feed it more than 128 you need two (with three i believe the max is 2048, but HV should be enough for most builds). If you connect it to an EU source stronger than it can take, it will blow up. Overclocker upgrades change nothing about this, only transformers do.
The breakpoints are easily calculable. For a recycler (the math is similar on other machines but with different entry points so differing results):
If you have 4 overclocker upgrades, it takes 21 eu/t to run at full speed and thus LV voltage (32 eu) is enough.
If you have 5-6 overclockers, it takes 48 and 110 eu/t respectively to run at full speed and thus MV voltage (128 eu) is needed. If you connect an mfe to it you need to have an overclocker upgrade or it will blow up.
If you have 7 overclockers, it takes 253 eu/t to run at full speed and thus require HV voltage (512 eu). If you connect it to an MFSU or other HV source you need two overclockers or it will blow up.
If you have 5 overclockers and no transformers and connect to a batbox it'll recieve 32 eu/t. It will not blow up but will not work at full speed either, I think speed will be roughly equivalent if you keep the 5 in or take one out, but with the 5 in it will drain 32eu/t instead of 21. The same is true for having 7 overclockers with MV voltage and a single transformer, it will not blow up but will not perform optimally either.
If you're unsure of how things work it could be better to start of with the lower voltages and test your way through; there is both less risk of stuff blowing up and each produced scrap will cost far less EU. Only benefit of many overclockers in one recycler rather than a few overclockers in a few recyclers is potentially easier routing and saved space (but getting and making room for HV might take more place than LV depending on setup).
Edit: If you want to do the maths for other machines it's really simple too. Just take the duration of an operation in seconds, multiply by 20. Also look at the EU/operation on the wikis. Then use these formula (original time per operation = T, OC = number of overclockers, original energy per operation = EU)
Time per operation in ticks: T*(0.7^OC)
Operations per second: 20/(T*0.7^OC)
EU per operation: EU*(1.6^OC)
EU consumption per tick: (EU*1.6^OC) / (T*0.7^OC).
If EU consumption per tick > 32, then one transformer and proper energy is needed. If it's >128, two transformers are needed. If >512, three are needed. If the machine can normally take higher voltage this need is reduced.
So the macerator for example take about 20 seconds (thus 400 ticks) and consume about 800 EU according to the wiki. Thus, with four overclockers, the eu/t math looks like this:
(EU*1.6^OC)/T*(0.7^OC)
(800*1.6^4)/(400*0.7^4)=54 eu/t
and it produces about .2 operations per seconds (so once every 5 seconds).
Since it requires more than 32 eu, you need one overclocker upgrade and access to medium voltage (from an mfe for example)
