Dell Vostro 3900 Memory Kit

This 16 GB kit contains two 8 GB DDR3 DIMMs built for the Dell Vostro 3900. It targets owners of that specific desktop who need to reach the 16 GB maximum supported by a 64-bit operating system. The modules are non-ECC and unbuffered, matching the system requirements.

Straightforward DIMM Installation

Installation follows the standard desktop DIMM procedure: power down, open the case, align the 240-pin modules with the slots, and press until the retention clips click. The kit uses major-brand chips to avoid the incompatibility issues that generic modules can introduce. No heat spreader is fitted, so clearance is rarely a concern.

16 GB Total Capacity Limit

The Vostro 3900 supports a maximum of 16 GB with a 64-bit OS, and this kit provides exactly that amount in a matched pair. Buyers who want more storage than 16 GB cannot use this system. The modules run at 1600 MHz with CL11 timings at 1.5 V.

Questions about this item

How do I verify the kit is running at 1600 MHz and CL11 after installing it in my Vostro 3900?

Open Task Manager or CPU-Z and confirm the memory frequency reads 800 MHz (double-data-rate 1600) with timings of 11-11-11 at 1.5 V.

What exactly ships in the box and is anything else required for installation?

The package contains two 8 GB 240-pin DDR3 DIMMs; no additional parts or tools are needed for the Vostro 3900 slots.

Why choose this 16 GB (2×8 GB) CL11 kit instead of a single 16 GB module?

The dual-channel pair matches the Vostro 3900's two-slot maximum of 16 GB and keeps latency at 11-11-11.
