I actually switched Ram of 8GB DDR3L from an HP Elitebook 4th Generation to Dell 3320m. As Hp elitebook uses DDR3L of 1.35 V now its running 1.5 DDR3 but with an error at startup, i.e 2E3 incompatible DDr3 type. On the other hand Dell 3320 which works on 1.5 V memory is now running fine on 1.35 V DDR3L. Is that an issue for any of the laptops as the official forums of both dell and hp discourages this idea.
