Turns out setting memory to 3266mhz wasn't a good idea. I got a random restart and saw I got constant errors in the event log, that kept going until I changed memory speed to 3200mhz. I really hope that was the reason for the random restart, since I obviously can't be sure of that. Windows really should inform you of when hardware errors occur.
After that I set the CPU voltage offset down by quite a bit since precision overboost seems to like setting voltage a bit too high and it lowered temperature by 5C and fan noise by a lot without any apparent performance or stability loss yet. Yes it's a great idea to induce more potential stability problems before I'm sure what caused the first one.
I should probably be able to get even better speeds or temperatures with some experimenting. But I'm worried about breaking something. Or just spending too much time on it.

Pure gaming with those specs? Stick with 8GB until you run into problems. If you're multitasking while gaming you might see some benefit going for 16GB.
