I found conflicting information on the usability of a SODIMM DDR3L module, low voltage (1.35v), as a replacement for a DDR3 module (1.5v), including the mention from someone who has a computer store.
That brings a question on the memory slots themselves:
Are there motherboards that can operate memory slots at two different voltages (1.35v or 1.5v), or is that voltage always fixed at either 1.35v or 1.5v?
