DDR3 & DDR3L are the same thing (DDR3L stands for DDR3 Low voltage and applies to our 1.35V DRAM) This is a dual voltage piece and can operate at 1.35V or 1.5V New (15) from $40.00 + FREE Delivery. DDR3L modules are backwards compatible with DDR3 by design. Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35 volts and are branded as DDR3L if they run properly. Other than that, there’s no difference between them. RE: DDR3 on a DDR3L slot Do yourself a favor and buy the Kingston DDR3L memory and save yourself the headache, I have a new 17r 3737 only 4GB memory made by Kingston, went on amazon and found Kingston 8GB DDR3L 1600mhz and slapped it in and no problems, shows I have 12GB memory and runs faster with Windows 8.1, so I wouldn't install just the.

yes it is correct, that they should use the same Chips. So from a functionallity point of view it is really just the same compatibility issue as with DDR3 from one vendor to another vendor (or even just for one die shrink to the next die shrink).
JEDEC defines that the DIMM needs to be backward compatible. So if a JEDEC compliant DIMM is operating at 1.5V should be tested and verified from the vendor. But not too many DIMM vendors really state that the DIMM is JEDEC compliant.
E. g. I have seen DIMMs with devices not supporting specific CL that they would need to support to be JEDEC compliant ..
And in this case thre is no need that the DIMM really is backward compatible (even if it is just a question of Speed, or reliability over time).
Even standard DIMMs are theoretically interchangable, there are many compatibility issues between motherboard, controller and DIMM out there .. and DDR3L will not make it better ..
Guess thats the usual difference between theory and praxis ..
and so I prefer to look at the DIMM spec and at least verify that the 1.5V is a supported voltage on a DDR3L DIMM if I intend to use it in a DDR3 System…
