32GB DDR4 RDIMM Server Memory

This Samsung module provides 32GB of DDR4 capacity in an RDIMM form factor for registered server platforms. It targets administrators upgrading or populating memory channels in compatible enterprise systems.

Registered DIMM build quality

The registered design places a register between the memory chips and the system memory controller to reduce electrical load per channel. Standard 288-pin DDR4 edge connectors ensure mechanical compatibility with server DIMM sockets.

Verify platform compatibility

Confirm that your motherboard or server chassis supports DDR4 RDIMM modules at the required rank configuration and population rules. Buyers needing unbuffered UDIMM or LRDIMM variants should select a different module type.

Questions about this item

What DDR4 interface standard does this Samsung M393A4K40BB2-CTD module use, and what does it cap in practice?

It runs on the DDR4 interface as a registered DIMM, so the memory controller sees a buffered command and address bus that limits electrical load to one load per rank instead of one per chip.

What physical slot and form factor does this 32GB RDIMM need to fit?

A standard 288-pin DDR4 RDIMM socket; the module height matches the JEDEC RDIMM outline so it clears normal server heatsinks.

How is this module installed, and what step do people get wrong?

Align the off-centre notch with the key in the 288-pin slot, press straight down until both ejector tabs click locked, and verify the tabs are fully seated — the common mistake is stopping when resistance rises before the tabs engage.
