1600 RAM, 1.35v or 1.5v for HP Elitebook 8560p? and will the voltage be lowered ?

[crooked windows]

HP Elitebook 8560p needing max DDR3 SODIMM RAM upgrade.(yik Gaming on a dead dog but it's all I got for now) Looking at 1600 instead of 1333 (as it's one that's locally available) and others are for MAC's, which I have been told, the only different is that its 1.35v.

I have limited options and some RAM advertised says it is 1.35/1.5v. Another has 1.4v specs which I guess is for either or , doesn't matter.
Another question is cl9 worth it over cl11 timing or is it negligible?

my system has windows 7 pro running on an Intel 500GB SSD so maybe faster cl numbers are worth it?

Any ideas would be greatly appreciated
UPDATE: seems I have found some answers already; although some experts in the field give opposite answers, go figure. So 1.35 works on 1.5 , solong as it says DDR3L and 1600 will work.
Still curious to know if the voltage will drop to 1.35v or the RAM gets 1.5v rammed down its throat. Both these answers were given by so-called experts, so whos correct? The word MAC on RAM only means it works on macs too. They just get fleeced for it.

DDR3L is actually normal DDR3, but they take the best specimens during the production (the ones that can run at 1.35 volts) and brand them as L. In other words, an L stick will run even better than a standard one, since it has a higher OC potential, but a standard stick will struggle in a 1.35V slot because it will need heavy underclocking to get stable performance.

As for speed vs cycles, you need to ballance them. A cl11will probably be fine in your case, as long as the speed is at least 1600.

EliteBook 8560p will support DDR3L 1600MHz as well.

General rule.
DDR3 Slot - Support DDR3 (1.5v) and DDR3L (1.35v)
DDR3L Slot - Support DDR3L (1.35v) only.
