Server memory upgrade kit

This 32GB kit contains two 16GB DDR4 RDIMM modules built for servers and workstations. It adds registered ECC memory to systems that require error correction and signal buffering. The dual-channel kit is designed for compatible DDR4 platforms only and will not work in desktop or laptop computers.

Registered DIMM with 288-pin interface

Each module uses a 288-pin DDR4 form factor and registered signalling to reduce electrical load on the memory controller. Dual-rank x8 organisation allows higher density per channel. The modules operate at the standard 1.2V DDR4 voltage and have no heat spreader, so they fit in tight server DIMM slots without clearance issues.

DDR4 2133 speed with CL15 latency

The memory runs at 2133 MT/s (PC4-17000) with a CAS latency of 15 cycles. This specific speed and latency combination determines whether the kit matches your system's qualified memory list. Verify your platform's supported DDR4 speeds before purchase to ensure compatibility.

Questions about this item

What DDR4 speed and PC4 rating does this kit run at, and what is the practical bandwidth limit?

The modules are rated DDR4 2133 (PC4-17000), which caps real-world throughput at 17 GB/s per channel.

What physical slot and pin count does this 288-pin RDIMM require?

It fits a standard 288-pin DDR4 DIMM socket on server or workstation boards; desktop and laptop slots are not compatible.

How do I install the two 16 GB sticks for dual-channel operation, and what step is often missed?

Place one module in each channel (usually slots of the same colour) and press firmly until both side clips click; forgetting to seat both ends evenly is the common error.
