4GB DDR4 2133 Module for Desktop Upgrades

This 4GB DDR4 2133 DIMM targets owners of compatible desktop systems who need a straightforward capacity increase. It runs at the standard 1.20V DDR4 voltage and uses a single-rank 1Rx16 organisation. The module is validated as a direct replacement for the Samsung M378A5244CB0-CPB part number and is tested for AMD and Intel platform compatibility.

Low-Voltage Operation Keeps Thermals Simple

Operating at 1.20V, the module draws minimal power and generates little heat during typical desktop workloads. No heatsink or active cooling is required and the unbuffered design adds no electrical load to the memory controller. Acoustic impact is negligible because the component has no moving parts and relies on case airflow alone.

288-Pin UDIMM Fits Standard Desktop Slots

The 288-pin DIMM form factor slots into any desktop motherboard that supports DDR4 2133 unbuffered non-ECC memory. A single 4GB stick leaves remaining slots free for future expansion. Builders should confirm the board's qualified vendor list before installation to ensure the 1Rx16 density is supported.

Questions about this item

Will this 4GB DDR4 2133 module fit a desktop board with 288-pin DIMM slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and 1.2V voltage, so it installs in any desktop motherboard that supports DDR4 2133 or faster unbuffered non-ECC memory.

Can I add this stick alongside my existing DDR4 2133 RAM to run in dual channel?

Dual-channel operation requires matched capacity and timing on each channel; this single 4GB 1Rx16 module will work, but for dual channel you need a second identical stick or a kit with the same specs.

Is this a direct replacement for the Samsung M378A5244CB0-CPB module?

Yes, the product is listed as a compatible replacement for the Samsung M378A5244CB0-CPB, matching its 4GB capacity, DDR4 2133 speed, 1Rx16 organisation and 1.2V voltage.
