RIMLANCE RSO12800LD8C4 4GB DDR3 1600MHz 1.35V SODIMM 2RX8

4 GB DDR3 SODIMM Upgrade

This RIMLANCE module adds 4 GB of DDR3 memory to a laptop using a 204-pin SO-DIMM slot. It runs at 1600 MHz and follows the PC3-12800 standard. The low 1.35 V operating voltage reduces power draw compared with standard-voltage DDR3. Unbuffered, non-ECC design matches typical notebook requirements.

Suits owners of compatible DDR3 notebooks

The single 4 GB stick works for users who have a free slot or are replacing one module in a system that accepts PC3-12800 SO-DIMMs. 2RX8 organisation fits the majority of mainstream laptop memory controllers. Buyers whose laptops only accept registered or ECC memory cannot use this module. Systems limited to lower speeds will still run the memory at the highest supported rate.

1.35 V low-voltage operation

This voltage is the key specification that determines whether the module matches the laptop's memory controller requirements. Standard DDR3 SO-DIMMs often run at 1.5 V, so a 1.35 V part is needed when the manufacturer specifies low-voltage memory. If the service manual calls for 1.5 V modules, this stick may not be the correct choice.
