Upgrade for Samsung DDR4 modules

This 4 GB DDR4 2133 MHz module replaces Samsung M378A5143DB0-CPB and M378A5143EB1-CPB parts. It fits standard 288-pin desktop DIMM slots and runs at the DDR4 standard 1.2 V. The kit targets owners of compatible desktops who need a straightforward capacity increase.

Thermals noise and power draw

Operating at 1.2 V keeps power draw low and heat output modest for a desktop DIMM. The module is unbuffered and non-ECC, so it adds no active cooling requirement. Silent operation is assured because memory has no moving parts.

Tested reliability and support

Every unit undergoes quality assurance testing before shipment to verify dependable performance. A-Tech backs the module with a lifetime warranty and provides United States based technical support for pre-sale and post-sale questions.

Questions about this item

How do I install the 288-pin DIMM and which step often goes wrong?

Align the notch on the module with the slot key, press firmly until both side clips snap shut, and confirm the module sits flat; the common mistake is stopping before the clips fully engage.

What maintenance or replacement will the 4GB DDR4 module need later?

No routine maintenance is required; if errors appear, reseat the DIMM or test with a single stick to isolate a faulty module.

What limit appears first when the 2133 MHz memory runs under sustained load?

The 1.2 V standard voltage and JEDEC 2133 MHz rating cap performance; the module will not exceed these specifications without manual overclocking.
