Dell Vostro 3900 4GB DDR3 upgrade

This 4GB DDR3 1600MHz module is built specifically for the Dell Vostro 3900 desktop. It uses a 240-pin DIMM form factor with a 1Rx8 rank configuration and runs at 1.5V. The non-ECC, unbuffered design matches the original system requirements for a direct drop-in installation.

CL11 11-11-11 timing under load

The module operates at CL11 with 11-11-11 timings at the rated 1600MHz speed. Major brand chipsets are used to maintain stability during sustained workloads rather than only brief bursts. The absence of a heat spreader relies on the chassis airflow of the Vostro 3900 to keep temperatures in check over long sessions.

Expands from 2-slot 16GB ceiling

The Vostro 3900 provides two memory sockets with a maximum supported capacity of 16GB on a 64-bit operating system. Adding this single 4GB stick increases total memory without occupying both slots, leaving room for a second module later. Buyers who need more than 16GB total capacity or who require ECC error correction cannot use this kit.

Otázky k tomuto produktu

Does this 1.5V DDR3 module run cool and quiet during all-day use in a Vostro 3900?

The stick uses standard 1.5V DDR3 with no heat spreader; it relies on case airflow and adds negligible heat or noise inside the chassis.

What must the Vostro 3900 already have for this 240-pin DIMM to install and work?

A free DDR3 DIMM slot — the system supports two slots and up to 16GB total with a 64-bit OS — and the board must accept non-ECC unbuffered memory.

Will this CL11 1600MHz stick work alongside the original memory in a Vostro 3900?

Yes — it matches the Dell-qualified PC3-12800 1600MHz spec, so the system will run both modules at the supported speed and timings.
