Server-ready 16GB DDR4 module

This A-Tech DDR4 2933MHz ECC RDIMM is built for server and workstation platforms that require registered memory with error correction. The single 16GB module delivers 2Rx8 organisation and CL21 latency at the standard 1.20V operating voltage.

Registered ECC with 2Rx8 organisation

The registered DIMM design and ECC function are the decisive specification; systems that require unbuffered or non-ECC memory cannot use this module. Verify your platform supports registered ECC DDR4 before purchasing.

16GB capacity for typical workloads

At 16GB this module handles common virtualisation, database and multitasking loads in a single slot, leaving room for additional DIMMs if the board has free sockets. It reaches its limit when applications demand more memory than the total installed capacity allows.

Questions about this item

What real-world difference does 2933 MT/s make in a server?

The 2933 MT/s rating means each module can transfer data at up to 2933 million transfers per second, giving the memory controller more bandwidth for multi-threaded workloads.

How does the registered DIMM interface affect speed?

The RDIMM register buffers address and command signals, adding one cycle of latency but allowing larger memory populations without signal degradation.

Will this 288-pin DIMM fit my server board?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor; verify your platform supports registered ECC DDR4 before installing.
