Capacity and Role

This A-Tech module provides 32GB of DDR4 server memory in a single registered DIMM. It targets administrators who need to expand ECC-protected capacity on compatible workstation or server platforms. Buyers seeking non-ECC or unbuffered modules for consumer desktops should look elsewhere.

Registered ECC and Rank

The decisive specification is the 2Rx8 registered ECC organisation combined with a CL22 latency at 3200MHz. Systems that require registered error-correcting DIMMs with this exact rank configuration will accept the module; platforms limited to unbuffered memory cannot use it.

Sustained Operation

Rated at 1.20V standard DDR4 voltage, the module maintains stable throughput during continuous workloads. Quality assurance testing validates reliable performance under prolonged load rather than only in short bursts.

Questions about this item

What does the 3200 MHz speed mean once the module is installed in a server?

The module runs at 3200 MT/s on a DDR4 bus, delivering PC4-25600 bandwidth while the registered buffer and ECC keep data stable under sustained server workloads.

How does the RDIMM interface and PC4-25600 rating limit real-world throughput?

The 288-pin DDR4 RDIMM interface caps transfer rate at the PC4-25600 specification; the registered buffer adds one cycle of latency but allows larger memory populations per channel.

What physical slot and clearance does this 2Rx8 ECC RDIMM need to fit?

It requires a standard 288-pin DDR4 DIMM socket; the 2Rx8 organisation and registered design fit any server board qualified for 32 GB RDIMM modules.
