16 GB DDR4 ECC RDIMM for servers

This 16 GB DDR4 2933 MHz module is built for servers and workstations that require registered ECC memory. It replaces Hynix HMA82GR7CJR4N-WM, HMA82GR7DJR4N-WM and HMA82GR7JJR4N-WM parts in compatible systems. The single-rank 1Rx4 design uses major-brand chips at 1.2 V.

Registered ECC with CL21 latency

The module operates as a registered DIMM with ECC error correction and a CAS latency of 21 cycles. This combination is the deciding factor for platforms that mandate registered ECC memory at DDR4 2933 speed. Systems needing unbuffered non-ECC modules cannot use this part.

288-pin DIMM with lifetime warranty

The 288-pin DDR4 form factor fits standard server DIMM slots. A-Tech tests every module and backs it with a lifetime warranty plus US-based technical support. No additional accessories or software are included.

Questions about this item

What real-world throughput does DDR4 2933 PC4-23400 deliver once installed in a server?

The module is rated for a peak transfer rate of 23400 MB/s at 2933 MT/s; actual throughput depends on the platform's memory controller, channel population and workload.

How does the registered ECC RDIMM interface affect what the memory controller can address?

The register buffers address and command signals, reducing electrical load on the controller and allowing larger total capacities per channel than unbuffered DIMMs.

Will this 288-pin DDR4 DIMM fit a standard server memory slot?

Yes, it uses the standard 288-pin DDR4 DIMM form factor and 1.2 V operation required by DDR4 server platforms.
