Server DDR4 32GB RDIMM

This 32GB DDR4 3200 ECC registered DIMM targets server and workstation builders who need error-correcting memory for stable operation under heavy workloads. The 2Rx8 organisation and CL22 latency suit multi-socket platforms that require registered modules. It runs at the standard 1.20V DDR4 voltage.

Samsung M393A4G43AB3-CWE replacement

The module is a direct equivalent for the Samsung M393A4G43AB3-CWE part, so it replaces that specific OEM stick when a system calls for 32GB of PC4-25600 registered ECC memory. The jump is worth it when your board demands registered DIMMs and you need the full 32GB capacity in a single slot. Non-ECC or unbuffered memory will not work in those slots.

288-pin DIMM installation

Installation follows the standard 288-pin DDR4 DIMM procedure: align the notch, press firmly until the retention clips engage, then verify the module is seated evenly. The usual issue is mixing registered and unbuffered DIMMs on the same channel, which prevents the system from posting. Always confirm your platform supports registered ECC before ordering.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server memory slot?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor used by compatible server and workstation boards.

What is the correct way to seat this registered ECC module so the system recognises the full 32 GB?

Align the notch with the slot key, press firmly until both retention clips click, and verify in BIOS that the memory runs at 3200 MHz CL22 1.20 V.

When should I expect to replace this 2Rx8 RDIMM in a continuously running server?

DDR4 registered ECC modules typically run for many years; replace only if memory diagnostics report correctable errors that increase over time.
