4GB DDR3 1600MHz Desktop Module

This 4GB DDR3 module runs at 1600MHz with a CL11 latency and a 240-pin UDIMM form factor. It is built for desktop computers that accept DDR3 memory and need a straightforward capacity increase. The module is unbuffered and non-ECC, matching standard consumer motherboard requirements.

Suitable for DDR3 desktop upgrades only

It suits owners of compatible desktop systems looking to add 4GB of DDR3 1600MHz memory for everyday workloads. It is not for laptops or small-form-factor devices that require SO-DIMM modules, nor for servers or workstations that require registered or ECC memory. Buyers needing higher capacities per slot or faster DDR3 speeds must choose different modules.

1600MHz DDR3 speed rating

The decisive specification is the 1600MHz DDR3 speed rating, also labelled PC3-12800. Your motherboard and processor must support DDR3 at this frequency for the module to operate as intended. Verify the supported memory standard and maximum speed in your system documentation before purchasing.

Questions about this item

Will this module fit my desktop's DDR3 slots?

It uses the 240-pin UDIMM form factor standard for DDR3 desktop memory, so it fits any motherboard slot designed for DDR3 DIMMs.

Is this memory compatible with my non-ECC motherboard?

Yes, it is a non-ECC unbuffered module, which is the standard type used in most consumer desktop boards.

What does the CL11 timing mean for my system?

CL11 indicates a CAS latency of 11 cycles at 1600 MHz, which is the standard timing for DDR3-1600 modules.
