Ok.. shopping for 16gb sets of memory for my x220.. which I will be reliant on for 3 months.. (i only have 2x4gb right now)
1.35 volt low voltage ram gives around 1-2% increased battery life..
1.50 volt 1866mhz ram gives around 2-5% boost in performance, up to 20-30% boost in igpu-performance..
So... do I want the performance, or the battery life.. Hrrrmmm...
