8GB DDR3 1600 SODIMM for Dell XPS

This 8GB DDR3 1600 SODIMM is built specifically for Dell XPS 14 L421X and Dell XPS 15 L521X laptops. It uses a 204-pin unbuffered non-ECC layout running at 1.5V with CL11 latency. The module is JEDEC-standard and ROHS compliant for a warranty-safe upgrade.

Sustained load behaviour

Under continuous workloads the memory operates at its rated DDR3 1600 speed with CL11 timings and 1.5V voltage. The 2Rx8 dual-rank organisation helps maintain throughput when multiple applications or large files are open simultaneously. No heat spreader is fitted, so airflow in the chassis manages module temperature.

DDR3 SODIMM interface limits

The DDR3 SODIMM interface tops out at the 1600 MT/s data rate this module provides. Higher speeds or lower latencies would require a different memory generation that the laptop platform does not support. Capacity per slot is limited to the 8GB density of this stick.

Spurningar um þessa vöru

How much heat does the 1.5V DDR3 1600 SODIMM add when the laptop runs all day?

The module runs at standard 1.5V JEDEC voltage with no heat spreader, so thermal output matches the original Dell specification for the XPS 14 L421X and 15 L521X.

Does the 204-pin DDR3 SODIMM need a free slot or a matching module already in the XPS 14 L421X?

It installs in any vacant 204-pin DDR3 slot; the XPS 14 L421X and 15 L521X each have two slots, so one free slot is all that is required.

Will the CL11 2Rx8 8GB stick work beside the original 4GB DDR3 module in my XPS 15 L521X?

Yes, the 8GB 2Rx8 CL11 module is JEDEC-standard DDR3 1600 and will run in dual-channel with the factory 4GB stick at the system's default speed.
