Correct. There are places that sell conversion kits for them if you wanted to try and run them on 110v, but the cost is pretty prohibitive so it would probably be cheaper and easier to just have an electrician install a 220v outlet for you to run this as is. The market is definitely in need of a high powered and competitive 110v miner option.

So I've run the daemon the other day to sync it after a long time (months) and it kept getting visited by the OOM killer. I had 2 GB ram on that machine and after increasing to 4GB that stopped.
What is the current minimum amount of ram necessary for monerod these days?

Not many of us left here.
