Server ECC RDIMM Upgrade

This 32GB DDR5 module is built for workstations and servers that require registered ECC memory. It will not function in standard desktop computers and cannot be mixed with unbuffered or load-reduced DIMMs.

Registered DDR5 4800 CL40 Spec

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V on a 288-pin 2Rx8 layout. This exact specification decides whether the part matches the slot and the memory controller.

For JEDEC-Compliant Server Builds

Buyers maintaining or expanding JEDEC-standard server platforms using Samsung M321R4GA3BB0-CQK or M321R4GA3BB6-CQK equivalents will find a direct match. Builders needing unbuffered desktop RAM, load-reduced DIMMs, or a different speed grade should look elsewhere.

Perguntas sobre este artigo

How does the 4800 MT/s speed translate once the module is installed in a server?

The module runs at the JEDEC-standard 4800 MT/s data rate with CL40 latency, delivering PC5-38400 bandwidth when the platform supports DDR5-4800 registered memory.

What does the registered ECC interface mean for compatibility and error handling?

Registered ECC adds a register between the DRAM and the memory controller and provides single-bit error correction; it only works in server or workstation platforms that explicitly support RDIMM ECC memory.

What physical slot and keying does the 288-pin RDIMM require?

It needs a 288-pin DDR5 RDIMM socket; the module is 1.1 V, has no heat spreader and follows the standard RDIMM height so it fits normal server DIMM slots.
