Upgrade for DDR3 desktops

This module provides 4 GB of DDR3 1600 memory with CL11 timing at 1.5 V. It uses a 240-pin unbuffered non-ECC design that matches the JEDEC PC3-12800 standard. The black PCB has no heat spreader and fits standard desktop DIMM slots.

Ideal for basic desktop upgrades

It suits older desktops and workstations that require DDR3 1600 unbuffered memory. Systems needing ECC, registered modules, higher capacities, or newer DDR generations should choose a different product.

Fits standard DDR3 slots

The stick installs directly into any 240-pin DDR3 desktop motherboard slot without extra power or cooling. Adding it frees up system responsiveness for everyday multitasking and larger file handling.

Questions about this item

What motherboard slot is required for this 240-pin DIMM?

A desktop motherboard with a DDR3 240-pin DIMM slot is needed for this module to fit and operate.

Can I mix this CL11 1600MHz stick with existing CL9 DDR3 modules?

The system will run all modules at the slowest speed and highest latency, so this CL11 module will downclock to match CL9 timings.

How do I confirm the module runs at PC3-12800 after installation?

Check the memory tab in CPU-Z or your BIOS; it should show 800 MHz DRAM frequency (1600 MT/s) and CL11 timings.
