Server-grade DDR4 ECC RDIMM kit

This 64GB kit contains four 16GB registered DDR4 modules built for servers and workstations that require ECC error correction. Each module runs at 2133 MHz with a CAS latency of 15 and operates at the standard 1.20V. The 288-pin DIMMs use a dual-rank x4 organisation and are sold as a matched quad-channel set.

Registered DDR4 2133 bandwidth ceiling

The PC4-17000 interface caps peak throughput at 17 GB/s per module, so total system bandwidth scales with the number of populated channels. Registered buffering adds one clock cycle of latency but allows the memory controller to drive larger populations without signal degradation. ECC parity bits consume part of the data bus, reducing usable bandwidth slightly compared with non-ECC equivalents.

Upgrade from non-ECC or lower-capacity kits

Replacing unbuffered desktop DIMMs or smaller registered kits eliminates single-bit errors that can corrupt databases and virtualisation workloads. The jump is worthwhile when the platform supports registered memory and the workload demands data integrity at scale; it offers no benefit on consumer motherboards that cannot accept registered modules.

Questions about this item

Should I choose the 64GB quad-channel kit or a smaller capacity for my server?

The 64GB kit provides four 16GB modules for full quad-channel bandwidth on compatible server platforms.

What does the DDR4 2133 MHz rating deliver in a real server workload?

It runs at 2133 MT/s with CL15 latency at 1.20V, giving registered ECC throughput suited for multi-threaded server tasks.

Does the PC4-17000 designation limit the memory speed on my motherboard?

PC4-17000 confirms the 2133 MT/s data rate; the module will operate at that speed or downclock to the highest speed your platform supports.
