32GB DDR4 3200 ECC Registered RDIMM

This 32GB DDR4 3200 ECC Registered RDIMM uses Samsung chips and runs at 1.2V with CL22 latency. It is a 2Rx4 dual-rank module built to the PC4-25600 standard. The 288-pin form factor fits compatible server platforms. Supermicro certification confirms validated compatibility for qualified systems.

Suited for Supermicro servers needing ECC

This module suits administrators upgrading or repairing Supermicro platforms that require DDR4 3200 ECC RDIMMs. Buyers whose systems need unbuffered UDIMMs or a different speed grade cannot use this part. Workstations and desktops without registered DIMM support should look elsewhere.

Supermicro certified DDR4 3200 RDIMM

Supermicro certification means this specific part number has been validated for supported Supermicro motherboards and chassis. The certification reduces the risk of POST errors or instability caused by unqualified memory. Always cross-reference your system qualified vendor list before purchasing.

Questions about this item

How do I install this 288-Pin RDIMM and what alignment step is often missed?

Align the single notch on the module with the key in the DDR4 slot, press straight down until both side clips click, and verify the module sits evenly; the notch position is fixed for DDR4 RDIMMs so forcing it the wrong way bends pins.

What maintenance or replacement will this Samsung M393A4K40EB3-CWE module need over its service life?

No scheduled maintenance is required; keep the server's air filters clean so the 1.20V modules stay within thermal limits, and replace only if memory diagnostics report uncorrectable ECC errors.

What limit appears first when this 32GB 2Rx4 ECC Registered DIMM runs sustained workloads at 3200MHz?

The memory controller's maximum supported rank-per-channel and total capacity limits are reached before the module's own CL22 timing or 1.20V voltage ceiling becomes a bottleneck.
