Single 4 GB DDR3-1600 DIMM

This module delivers 4 GB of DDR3 memory at 1600 MT/s with CL9 latency. It fits standard 240-pin desktop slots and is suited for basic office PCs or older workstation upgrades.

Sustained throughput at PC3-12800

Running continuously at the rated 1600 MT/s speed, the stick maintains CL9 timings without a heat spreader. The unbuffered design keeps latency low for everyday multitasking and light content workloads.

Plain green PCB with gold contacts

The bare circuit board slips into tight spaces around large CPU coolers. Gold-plated 240-pin edge connectors resist oxidation and ensure reliable seating through repeated install or removal cycles.

Questions about this item

Will this single 4 GB DDR3 module fit a standard desktop DIMM slot?

Yes, it uses the 240-pin DIMM form factor that matches mainstream desktop motherboards with DDR3 slots.

What speed will the module run at if my board only supports DDR3-1333?

The module is rated for DDR3-1600 (PC3-12800) and will automatically down-clock to DDR3-1333 on a board limited to that speed.

Can I add this stick to an existing 4 GB DDR3 module for 8 GB total?

Yes, adding a second 4 GB DDR3 DIMM of matching voltage and timing will give 8 GB in dual-channel mode.
