Server DDR4 ECC RDIMM kit

This A-Tech kit provides 64 GB of DDR4 server memory across four 16 GB registered DIMMs. Each module runs at 2133 MHz with CL15 latency at 1.2 V and includes ECC error correction. The dual-rank x8 organisation suits multi-channel server and workstation platforms.

Suited for registered DDR4 servers only

The modules are built for systems that require 288-pin ECC registered DDR4 memory and will not work in desktop or laptop computers. Buyers who need non-ECC unbuffered memory or a different pin count should look at other memory types.

2Rx8 registered ECC at 2133 MHz

The dual-rank x8 registered ECC design at DDR4 2133 determines whether this kit matches the motherboard's qualified vendor list. Verify that your server or workstation supports 2Rx8 PC4-17000 registered modules before purchasing.

Questions about this item

Should I pick the 64 GB quad-channel kit or build the same capacity from single modules?

The kit provides four matched 16 GB modules tested together for quad-channel operation, avoiding timing mismatches that can occur when mixing separate sticks.

What does the DDR4 2133 MHz rating deliver in an actual server workload?

It runs at 2133 MT/s with CL15 latency at 1.2 V, giving a peak bandwidth of 17 GB/s per module for ECC-protected throughput in registered DIMM slots.

How does the 288-pin RDIMM interface limit speed or capacity in my platform?

The registered 288-pin DDR4 DIMM fits only server and workstation boards that support ECC RDIMM; it will not work in desktop or laptop memory controllers.
