32GB DDR5 ECC RDIMM for Samsung servers

This 32GB DDR5 4800MHz registered DIMM replaces Samsung M321R4GA3BB0-CQK and M321R4GA3BB6-CQK modules. It delivers ECC error correction and 2Rx8 organisation for server and workstation platforms that require registered memory. The module operates at the standard 1.1V DDR5 voltage with CL40 latency.

Registered DDR5 limits capacity per channel

Registered buffering adds a clock cycle of latency and reduces the maximum number of modules a memory controller can address per channel compared with unbuffered DIMMs. The 4800MHz PC5-38400 speed is the baseline DDR5 data rate; higher frequencies are not supported by this part. System firmware must be configured for registered ECC operation or the module will not initialise.

288-pin DIMM with Samsung chipset implies dense

The 288-pin DDR5 DIMM fits standard server memory slots and uses Samsung ICs in a 2Rx8 EC8 configuration. Registered signalling and ECC parity bits increase trace count on the PCB, so module height matches typical 1U and 2U clearance envelopes. Installers should confirm the motherboard qualifies this exact Samsung part number before deployment.

Questions sur cet article

How do I confirm this 32GB DDR5 4800MHz module matches the Samsung M321R4GA3BB0-CQK or M321R4GA3BB6-CQK part I need to replace?

Match the Samsung part numbers M321R4GA3BB0-CQK or M321R4GA3BB6-CQK on your existing module or system manual; this A-Tech module is built as a direct replacement for those exact part numbers.

What does the 4800MHz speed rating mean for actual throughput in my server?

The module runs at DDR5 4800, delivering a peak data rate of PC5-38400; real-world throughput depends on your CPU memory controller and how many channels are populated.

Is the 288-pin DDR5 DIMM interface the same as the 262-pin form factor mentioned in some specs?

DDR5 DIMMs use a 288-pin edge connector; the 262-pin count refers to the SO-DIMM form factor used in laptops, not this registered server DIMM.
