Schimb memorii laptop 2x4GB DDR3 low voltage cu 2x8GB DDR3 normal voltage
Schimb memorii laptop 2x4GB DDR3 low voltage cu 2x8GB DDR3 normal voltage. Functioneaza perfect dar nu sunt compatibile cu windows pe 64 bit pe un laptop cu chipset HM55.
Memoriile low voltage functioneaza la 1.35V, sunt mai reci si de obicei mai rapide si sunt compatibile si cu procesoarele peste generatia 4 de la Intel (Haswell), care nu accepta memorii cu voltaj 1.5.
Sunt notate cu DDR3L sau PC3L:
DDR3L‐800 (PC3L-6400), DDR3L‐1066 (PC3L-8500), DDR3L‐1333 (PC3L-10600), and DDR3L‐1600 (PC3L-12800)
Se pot verifica cu cpuz, in tab-ul SPD, unde arata tensiunea si denumirea pe fiecare modul din sloturile laptopului. Sau se citeste pe eticheta modelul de memorie.

DDR3L and DDR3U extensions
The DDR3L (DDR3 Low Voltage) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices.[31] The DDR3L standard is 1.35 V and has the label PC3L for its modules. Examples include DDR3L‐800 (PC3L-6400), DDR3L‐1066 (PC3L-8500), DDR3L‐1333 (PC3L-10600), and DDR3L‐1600 (PC3L-12800). Memory specified to DDR3L and DDR3U specifications is compatible with the original DDR3 standard, and can run at either the lower voltage or at 1.50 V.[32] However, devices that require DDR3L explicitly, which operate at 1.35 V, such as systems using mobile versions of fourth-generation Intel Core processors, are not compatible with 1.50 V DDR3 memory.[33] DDR3L is different from and incompatible with the LPDDR3 mobile memory standard.
The DDR3U (DDR3 Ultra Low Voltage) standard is 1.25 V and has the label PC3U for its modules.
