DDR3L is 1.35V
DDR3 is 1.5V
Some DDR3 RAM can run at 1.35V without problems and some cannot.
When mixed, both will run at 1.35V or 1.5V depending on the BIOS.
I have mixed both 1.35V and 1.5V RAM sticks before. No problems and stable for days too. Most important the BIOS must support it.
Yes, it depends on the board and bios. This is because some ddr3L board will not support ddr3 at all. So if you put 1.5v ram into the slot, it won't detect it. DDR3 is 1.5V

But if it can support, there will be no issues. Mixing different speed and size is not a problem but bios will select lower speed (eg. Ddr3 1600 and 1833, comouter will run at 1600)
