Target fit

This 16 GB DDR4 RDIMM is built for servers and workstations that require registered memory with error correction. The 1Rx4 organisation and 288-pin form factor suit multi-socket platforms where signal integrity across many modules matters more than low latency alone.

Upgrade path

It replaces unbuffered DDR4 DIMMs or slower registered sticks when the platform demands registered signalling and the memory controller supports DDR4 2666. The jump is worth it when the motherboard manual specifies RDIMM population rules that unbuffered modules cannot satisfy.

Sustained behaviour

Registered buffering reduces electrical load on the memory bus, allowing stable operation across full channel populations during long compute runs. The 2666 MT/s rate delivers consistent throughput without the voltage scaling or timing relaxations that higher-speed bins often require under continuous load.

商品問答

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

The module uses the 288-pin DDR4 RDIMM form factor, which matches the standard registered DIMM slots found in compatible servers and workstations.

What is the correct seating procedure for the registered 1Rx4 module, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the register LED sequence during POST to confirm the buffer is active.

When should the 16 GB DDR4 2666 registered DIMM be replaced in a production server?

Replace the module if ECC correctable-error counters rise steadily, if memory diagnostics report uncorrectable faults, or during a planned capacity upgrade.
