Slots De Ram Ddr3

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. 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.

Short for double data rate three, DDR3 is a type of DRAM (dynamic random-access memory) released in June 2007 as the successor to DDR2. DDR3 chips have bus clock speed of 400 MHz up to 1066 MHz, range in size from 1 to 24 GB, and consume nearly 30% less power than their predecessors. DDR3 RAM sticks for a desktop computer have 240 pins. For a laptop computer, DDR3 RAM sticks have 204 pins.

These memory chips can only be installed on a motherboard that supports DDR3 memory and are not backward compatible with DDR2 memory slots.

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…
