System-specific DDR3L module for Dell Inspiron 15

This 8 GB SODIMM is built to match the Dell Inspiron 15 (7559) memory specification. It installs in a 204-pin slot and runs at 1.35 V, matching the low-voltage requirement of the platform. The single-stick kit lets you add capacity without removing the original module.

Steady throughput at CL11 11-11-11 timings

Rated at 1600 MHz with PC3L 12800 bandwidth, the module maintains its CAS latency of 11 through extended workloads. Unbuffered, non-ECC operation keeps the signal path direct for consistent frame times during long rendering or compile sessions. The 2Rx8 organisation supports the dual-channel architecture when a second stick occupies the other socket.

Major-brand chips on a bare green PCB

No heat spreader is fitted, so the module sits low under tight notebook chassis clearances. The 204-pin edge connector aligns with the factory SO-DIMM socket for a secure press-fit. Builders needing 16 GB total capacity or ECC protection should look elsewhere, as this stick is a single-rank 8 GB non-ECC part.

Questions about this item

How much power does the 1.35 V DDR3L module draw when the Dell Inspiron 15 7559 runs all day?

The module operates at 1.35 V, the standard low-voltage level for DDR3L, so it draws less power and generates less heat than a 1.5 V DDR3 stick during continuous use.

What must the Dell Inspiron 15 7559 already have for this 204-pin SO-DIMM to work?

The laptop needs a free DDR3L SO-DIMM slot; the system ships with two slots and supports up to 16 GB, so one 8 GB stick fits directly.

Will the CL11 1600 MHz stick run correctly beside the original memory in my 7559?

Yes, the JEDEC-standard 1600 MHz CL11 timings match the platform spec, so the new module will down-clock automatically if the existing stick is slower.
