OWC 4GB DDR3 1600 Desktop Upgrade

This OWC module adds 4GB of DDR3 memory to compatible Dell Inspiron desktops. It is built as a single unbuffered 240-pin UDIMM rated for 1600 MHz operation. The kit targets owners of the Inspiron 3647 or 3847 seeking a straightforward capacity increase.

1Rx8 CL11 1.5V JEDEC Specification

The decisive spec is the 1Rx8 organisation combined with CL11 latency at 1.5V, matching the JEDEC PC3-12800 standard for these systems. A module with different rank, voltage or timing will not be recognised by the Dell motherboard. This part meets that exact requirement.

Low-Power Unbuffered Operation

As an unbuffered DIMM without a heat spreader, the module draws minimal power at the standard 1.5V DDR3 voltage. No active cooling is required and acoustic output is zero. Typical desktop workloads remain within the thermal envelope of the original chassis design.
