Dell Inspiron 3646 memory upgrade

This 4GB DDR3L SODIMM is built specifically for the Dell Inspiron 3646 desktop. It provides a direct, warranty-safe way to increase system memory for everyday computing tasks. The module arrives new and ready for immediate installation by any user comfortable opening the case.

JEDEC and RoHS compliant module

The stick meets JEDEC-standard DDR3L specifications and is RoHS compliant, ensuring it operates within the original equipment manufacturer's electrical and environmental limits. This compliance protects the system warranty and guarantees stable operation at the rated 1.35V. No additional software or drivers are required for the upgrade to function.

Single 4GB DDR3L 1600 CL11 stick

Capacity is fixed at 4GB running at DDR3L 1600 (PC3L-12800) with CL11 latency. The module is unbuffered, non-ECC, single-rank 1Rx8 and uses a 204-pin SODIMM form factor. Systems needing more than 4GB total memory or a different speed grade will require a different module.

Questions about this item

Will this 204-pin DDR3L SODIMM require any firmware updates or periodic re-seating after installation in the Dell Inspiron 3646?

No firmware updates are needed for this JEDEC-standard DDR3L module. Once seated in the SODIMM slot, it requires no further maintenance or re-seating under normal operation.

What is the first limitation encountered when running this CL11 1.35V module continuously at DDR3L 1600 speeds?

The CAS latency of CL11 and single-rank 1Rx8 organisation set the timing and bandwidth ceiling during sustained workloads.

How much heat and power does this non-ECC unbuffered module produce during all-day operation?

Operating at 1.35 V without a heat spreader, the module draws low power and runs cool enough for passive airflow inside the Dell Inspiron 3646 chassis.
