This is a good performing DDR3 RAM module, with an attractive and compact heat spreader. This RAM’s latency is a bit high, but it’s still a fast RAM kit offered at an affordable price. It is pretty fast, affordable, and reliable, making it one of the best DDR3 RAM options on the market. In laptop RAM slots the pins on the bottom connector are a little curved so that it can push the RAM to make contact with the pins on the top connector when we press-fit the RAM in its place. The fit is such that the RAM is held in place with all 204 pins in contact. In my laptop, the pins on the second slot are not having enough curvature on. DDR3 DIMMS require a 240-pin slot and 1.5 operating voltage. A slot for DDR3 memory is keyed differently than DDR2 or DAR. Do not attempt to install DDR3 memory into a motherboard designed for DAR or DDR2. Doing so can permanently damage the motherboard and DIMM. Number of Memory Slots: 4×240pin; Memory Standard: DDR3 1866/ 1600/ 1333/ 1066; PCI Express 2.0 x16: 3 x PCIe 2.0 x16 (dual x16 or x16/x8/x8).1 1 x PCIe 2.0 x16 (x4 mode, black).1: When running dual graphics cards, be sure to insert the card in the first and third PCIex16 slot to get the best performance. Onboard Video Chipset: None. RAM slot, socket, or a memory slot is a gap on your computer’s motherboard where you can insert your RAM. Depending on the motherboard type, there might be up to four memory sockets. If you have a high-tier motherboard, you can even have more.

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.

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…
