Server DDR4 ECC RDIMM

This 32GB registered DIMM is built for servers and workstations that require error-correcting memory. It operates at DDR4 3200 speed with a CL22 latency and 1.20V voltage. The module uses a single-rank x4 organisation and major-brand chips. It is not compatible with desktop or laptop computers.

Registered ECC with 1Rx4 layout

The single specification that decides fit is the registered ECC RDIMM interface combined with a 1Rx4 rank structure. Your system must explicitly support DDR4 ECC registered DIMMs and accept a single-rank x4 module. Verify the motherboard or server manual for this exact configuration before ordering.

Straightforward DIMM installation

Installation follows standard 288-pin DIMM seating: align the notch, press firmly until the retention clips click, and follow the system's channel-population rules. The most common issue is mixing registered and unbuffered modules or populating slots in an unsupported order, which prevents the system from posting.

Questions about this item

What does the DDR4 3200 speed rating mean for actual throughput in a server?

DDR4 3200 transfers data at 3200 MT/s, so each channel moves up to 3200 million transfers per second when the system runs the module at its rated speed.

How does the PC4-25600 designation limit real-world performance?

PC4-25600 is the peak bandwidth label for DDR4 3200; the module cannot exceed the transfer rate implied by that rating in any configuration.

Will the 288-pin registered DIMM fit in a standard server memory slot?

Yes, the 288-pin RDIMM form factor matches the DDR4 DIMM sockets used in compatible servers and workstations.
