CMS 4GB DDR3L 1600 SODIMM for Alienware Alpha

This 4 GB module upgrades the Alienware Alpha with DDR3L memory at 1600 MHz and 1.35 V. It uses a 204-pin SO-DIMM form factor with CL11 timing and unbuffered, non-ECC operation. The single-rank design fits one of the system's two slots for a straightforward capacity increase.

Suits owners adding a single 4 GB stick to reach 8

Builders who need the full 16 GB maximum should populate both sockets instead. The 1.35 V DDR3L specification means this stick is not compatible with standard 1.5 V DDR3 platforms. Systems requiring ECC or registered memory must look elsewhere.

Voltage is 1.35 V DDR3L — confirms fit

The 1.35 V rating matches the Alpha's low-voltage requirement and prevents damage from standard 1.5 V modules. Verify your chassis has a free SO-DIMM slot before ordering. The CL11 11-11-11 timing aligns with the platform's native memory controller settings.

Questions about this item

How does the 1600 MHz speed translate inside an Alienware Alpha?

The module runs at DDR3L 1600 (PC3L 12800) with CL11 timing, delivering the rated bandwidth when the Alpha's memory controller operates at 1.35 V.

What does the DDR3L 1600 (PC3L 12800) interface cap in practice?

The DDR3L SO-DIMM interface limits transfer rate to 12800 MB/s; the Alpha's two slots can each accept one 204-pin stick up to the system maximum of 16 GB.

Will the 204-pin stick fit the Alpha's SODIMM slot without a heat spreader?

Yes, the unbuffered 1Rx8 module uses a standard 204-pin SO-DIMM form factor with no heat spreader, matching the Alpha's two SODIMM sockets exactly.
