A-Tech 4GB DDR4 2400MHz Module

This 4GB DDR4 DIMM runs at 2400MHz with a standard 1.2V voltage. It is an unbuffered, non-ECC module built for desktop systems. The single-rank 1Rx8 layout uses a 288-pin connector. It serves as a direct replacement for the Samsung M378A5143EB2-CRC part.

Fits Standard DDR4 Desktop Slots

The module installs into any desktop motherboard with a DDR4 DIMM slot supporting 2400MHz operation. Its 1.2V requirement matches the DDR4 standard voltage, so no special power configuration is needed. The unbuffered design keeps the memory controller load low. Builders should confirm their platform accepts 4GB non-ECC UDIMMs before purchasing.

Steady 2400MHz Throughput Under Load

Rated at PC4-19200, the stick sustains its tested 2400MHz frequency during extended workloads. The 1.20V operating voltage helps maintain thermal stability without active cooling on the module itself. Quality assurance testing validates reliable performance across continuous multitasking sessions. Systems limited to lower memory speeds will downclock the module automatically.

Questions about this item

Will the 2400 MHz speed hold under sustained load?

The module is tested at 2400 MHz and runs at the standard 1.2 V, so the rated frequency is maintained during continuous operation.

How much heat or noise does this DIMM produce when running all day?

As a passive 1.2 V DDR4 UDIMM it generates minimal heat and no audible noise, even under 24-hour workloads.

What motherboard slot is required for this 288-pin module?

A desktop motherboard with a DDR4 DIMM slot is needed; the 288-pin form factor fits only DDR4 sockets.
