[Johny-Franko]

Hi guys, what could possible happen when i use in HP 4340s pc3 ram instead pc3L, originally is pc3L there and i want to connect pc3 with the same specs and lookout, Can i harm the system? Can i try combination of both rams in this laptop?

 Thank you in advance

They use different voltage, DDR3L is backward compatible with DDR3 but you won't be able to get benefit of DDR3L
