Elpida 4 GB DDR3 SODIMM

This 4 GB DDR3 SODIMM runs at 1600 MHz with PC3 12800 bandwidth. It uses an unbuffered 1.5 V design in a 204 pin form factor. The module is organised as 1Rx8 with 512Mx64 density.

Sustained load behaviour

The memory operates at standard JEDEC timings including CL11 latency. Unbuffered architecture means the memory controller handles all timing directly. Continuous throughput stays at the rated 1600 MHz without downclocking.

Compatibility checks

Verify your laptop accepts DDR3 SODIMM modules at 1.5 V. Confirm the system supports 4 GB single rank sticks and 204 pin layout. Check the service manual or existing RAM part number before ordering.

Questions about this item

How much power does the 1.5 V 4 GB DDR3 1600 module draw during continuous operation?

It operates at the standard DDR3 voltage of 1.5 V; actual power draw depends on the notebook’s memory controller and workload.

What must my laptop provide for this 204-pin SODIMM to function?

A DDR3 SO-DIMM slot that accepts 1.5 V unbuffered modules and a memory controller able to run at 1600 MT/s (PC3-12800).

Can I pair this CL11 1Rx8 stick with an existing DDR3 module in the second slot?

Yes, provided the other module is also DDR3; the system will run both at the lowest common speed and latency.
