4GB DDR3L 1600 SODIMM for Dell Inspiron 3521

This 4GB module is a 204-pin DDR3L SODIMM rated at 1600MHz (PC3L-12800) with CL11 timings and 1.35V operation. It is an unbuffered, non-ECC stick built with major-brand chips and no heat spreader. The part is guaranteed compatible with the Dell Inspiron 15 (3521) notebook.

Suitable for single-slot upgrades on the Inspiron

The system accepts two modules for a maximum of 16GB, but modules must be installed in pairs to enable dual-channel mode. Buyers who want more than 4GB of total memory or who need dual-channel bandwidth should order a second identical stick. A 64-bit operating system is required to address the full 16GB capacity.

Handles everyday workloads.

One 4GB stick runs office applications, web browsing and light multitasking comfortably. Performance runs out when memory pressure exceeds the single-channel bandwidth or the 4GB physical limit, which the OS may report as 3.5GB or less depending on system allocation. Adding a matched second module doubles both capacity and throughput.

商品問答

Will this 204-pin DDR3L SODIMM fit and run in my Dell Inspiron 15 3521 notebook?

Yes, the module is system-specific for the Inspiron 15 3521 and uses the 204-pin DDR3L SO-DIMM form factor that the notebook accepts.

Can I install this single 4 GB stick alongside an existing module in the second slot?

The system has two sockets and supports up to 16 GB total; a single 4 GB module will work, though maximum dual-channel performance requires matched pairs.

How do I verify the stick is running at 1600 MHz with CL11 timing after installation?

Check the memory speed and CAS latency in the BIOS or a system-information utility; they should show 1600 MHz and 11-11-11 timings at 1.35 V.
