Server Memory Upgrade

This 16GB DDR4 3200 module is built for servers and workstations that require ECC registered DIMMs. It replaces Samsung M393A2K43DB2-CWE, DB3-CWE and EB3-CWE parts with a direct equivalent.

Thermals and Power Draw

Operating at the standard 1.20V DDR4 voltage, the module draws minimal power and generates low heat inside a chassis. Registered buffering reduces electrical load on the memory controller during sustained workloads.

Compatibility and Testing

Each unit is tested to meet PC4-25600 speed and CL22 latency specifications before shipping. The 2Rx8 organisation and 288-pin form factor match the original Samsung modules for drop-in installation.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the module with the key in the server DIMM slot, press down firmly until both side clips click shut, then verify in BIOS that ECC and registered mode are detected at 3200 MHz CL22.

What maintenance or replacement will this 16GB ECC RDIMM need later?

No routine maintenance is required; if a correctable error count rises or the module fails POST, replace the individual 2Rx8 stick — matched kits are not mandatory for single-slot upgrades.

What limit appears first when this 1.20V DDR4 3200 module runs sustained workloads?

The registered buffer and CL22 latency set the throughput ceiling; sustained write-heavy loads will hit the command-rate limit before the 1.20V thermal envelope becomes a factor.
