4GB DDR3 1333 MT/s Desktop Module

This single 4GB DDR3 UDIMM runs at 1333 MT/s with CL9 latency and a 240-pin layout. It is unbuffered and non-ECC, matching the standard desktop DIMM format. The module suits owners of older DDR3 systems needing a straightforward capacity increase.

Capacity and headroom

Four gigabytes covers everyday desktop workloads such as web browsing, office suites and light multitasking on a compatible DDR3 platform. Memory-heavy tasks like modern gaming, video editing or running multiple virtual machines will exhaust this capacity quickly. The single-module design leaves other slots free for future expansion if the board supports more.

CL9 latency at 1333 MT/s

The CL9 timing at 1333 MT/s defines the module's response speed and must match the memory controller's supported specifications. Systems requiring different latencies or higher DDR3 speeds may not operate correctly with this part. Verify the motherboard's qualified vendor list before purchase.

Questions about this item

Will this DDR3 1333 MT/s CL9 module run alongside my existing DDR3 memory in the same system?

This module operates at up to 1333 MT/s with CL9 latency. When mixed with slower DDR3 sticks the system typically runs all modules at the speed of the slowest one, so the CT51264BA1339 will downclock to match.

How can I verify the CT51264BA1339 is running at 1333 MT/s with CL9 timings after installation?

Check the memory speed and timings in your BIOS or UEFI setup screen, or use a system information tool such as CPU-Z inside the operating system to confirm the module reports DDR3-1333 and CL9.

Does the CT51264BA1339 package include only the 240-pin UDIMM or are there extra accessories?

The box contains the single 4GB DDR3 240-pin UDIMM module itself. No additional cables, brackets or software are supplied or required for installation.
