Capacity and Compatibility

This 16GB DDR4 module runs at 2400MHz with a PC4-19200 rating and standard 1.20V operation. The unbuffered, non-ECC 288-pin DIMM uses a 2Rx8 organisation and is tested as a direct replacement for Samsung M378A2K43BB1-CRC and M378A2K43CB1-CRC modules.

Sustained Workload Behaviour

Under continuous load the module maintains its rated 2400MHz frequency at the JEDEC 1.20V level without requiring overclocking headroom. Quality assurance testing verifies stability across extended sessions, so multitasking and heavier workloads see consistent throughput rather than throttling after a short burst.

DDR4 Interface Limits

The DDR4 2400 standard caps single-module bandwidth at the PC4-19200 figure, so total system throughput depends on the number of populated slots and the memory controller's maximum supported speed. Builders who need more capacity than a single 16GB stick provides must add modules within the platform's slot and density limits.

Questions about this item

Will this 16 GB DDR4 2400 MHz DIMM fit my desktop motherboard?

It uses the standard 288-pin DDR4 DIMM form factor and runs at 1.2 V; check your board's manual for supported DDR4 speeds and maximum capacity per slot.

Can I mix this module with my existing DDR4 memory?

Mixing is possible when speeds and voltages match; the system will run all modules at the slowest rated speed, so confirm your current RAM is also DDR4 2400 at 1.2 V.

Is this module a direct replacement for Samsung M378A2K43BB1-CRC or M378A2K43CB1-CRC?

Yes, the product is listed as a compatible replacement for both Samsung part numbers, matching capacity, speed, voltage, and 2Rx8 organisation.
