  • 2Rx8 288-pin DIMM fits standard DDR4 server slots

Server memory upgrade for Samsung replacements

This 16GB DDR4 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It serves as a direct replacement for Samsung part numbers M392A2K43BB0-CRC, M393A2K43BB1-CRC and M393A2K43CB1-CRC. Systems needing unbuffered UDIMMs or non-ECC memory cannot use this module.

DDR4 2400 registered DIMM constraints

The module operates at DDR4 2400 (PC4-19200) with a CAS latency of CL17 and a standard 1.2V voltage. Registered DIMMs add a clock cycle of buffering, so the memory controller must support registered operation; consumer desktop platforms that only accept unbuffered memory will not POST with this module installed.

2Rx8 rank and 288-pin form factor

This stick uses a dual-rank 2Rx8 organisation on a 288-pin DDR4 DIMM PCB. The rank configuration determines how the memory controller addresses the chips, so the motherboard must explicitly support 2Rx8 registered modules at this capacity.

Questions sur cet article

Should I choose the 16 GB module or a different capacity?

This listing is a single 16 GB DDR4 2400 ECC RDIMM. Other capacities are not offered here.

What does the 2400 MHz rating deliver in a real server?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency, providing the rated bandwidth when the platform supports that speed.

Does the 288-pin DDR4 RDIMM interface limit the usable speed?

The 288-pin registered DIMM form factor carries DDR4 2400 signals; the system memory controller ultimately caps the operating frequency.
