Server memory upgrade

This 8 GB DDR4 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It operates at 3200 MHz with a CL22 latency and runs at 1.20 V using a single-rank 1Rx8 organisation. The 288-pin form factor fits compatible DDR4 RDIMM slots in qualified systems.

Registered DDR4 constraints

Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing higher module counts per channel than unbuffered memory. This design requires a motherboard chipset and BIOS that explicitly support registered ECC operation. Consumer desktop platforms and most laptops cannot use registered modules and will not post with them installed.

Samsung M393A1K43FB2-CWE compatibility

The decisive specification is validated compatibility with the Samsung M393A1K43FB2-CWE part number. Only systems qualified for that exact module or an equivalent 8 GB DDR4 3200 1Rx8 ECC RDIMM should use this upgrade. Buyers without that verification should not purchase this module.

Questions about this item

Should I choose the 1Rx8 or a dual-rank version for my server?

This module is a single 8 GB stick built as 1Rx8; adding a second identical stick will run in dual-channel if your board supports it.

What does the 3200 MHz rating deliver in an actual system?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, so throughput and response match the rated speed when the platform enables it.

How does the 288-pin RDIMM interface limit compatibility?

The 288-pin registered ECC RDIMM form factor only fits server or workstation boards that accept registered DDR4 memory; it will not work in standard desktop slots.
