I notice OWC is selling 1600MHz DDR3L for the just released 2012 Macbook pro. Apple indicates that these machines use DDR3 which is a higher voltage/higher power than DDR3L. (FWIW, the retina MBP explicitly mentions the use of DDR3L).

Is it really okay to use DDR3L in the non-retina Macbook pros, or did OWC make a mistake? I'm worried the DDR3L might not be expecting a higher voltage. Does the macbook pro automatically lower the power supply voltage? Or is the DDR3L just capable of handling the higher voltage/higher power?
