16GB DDR4 2933 ECC UDIMM kit

This 16GB kit contains two 8GB unbuffered ECC modules that run at DDR4 2933 with a CAS latency of CL21. It is built for servers and workstations that require error-correcting memory and is not compatible with standard desktop or laptop computers.

Platform and slot check before ordering

Verify that your system supports DDR4 ECC UDIMM modules in a 288-pin DIMM form factor and that it can operate at 2933 MT/s or will down-clock automatically. Confirm the motherboard accepts single-rank 1Rx8 modules and that the memory voltage is 1.2V. Consult the system manual for the correct slot population order to enable dual-channel operation.

Thermals noise and power in normal use

The modules run at the standard DDR4 voltage of 1.2V and have no heat spreaders, relying on chassis airflow for cooling. They produce no audible noise because they contain no moving parts. Power draw scales with capacity and speed, so a pair of 8GB sticks at 2933 MT/s adds only a modest load to the system power budget.

Questions about this item

Does the kit include anything besides the two 8 GB modules, such as a heat spreader or installation tool?

The package contains only the two 288-pin DDR4 UDIMM modules. No heat spreader or extra accessories are included.

Why choose the 1Rx8 dual-channel kit over a single 16 GB stick or a 2Rx8 alternative?

The 1Rx8 dual-channel kit provides two single-rank modules that populate two channels for higher bandwidth, while a single stick would run in single-channel mode and a 2Rx8 design would present a different electrical load.

What does the CL21 rating mean for real-world server responsiveness?

CL21 indicates 21 clock cycles of latency at 2933 MHz, giving a low access delay that helps the server handle concurrent requests and large datasets more quickly.
