  • 20 V low voltage reduces power draw and heat
  • 288-pin unbuffered DIMM fits standard server and workstation slots

16 GB DDR4 ECC module for servers and workstations

This 16 GB DDR4 SDRAM DIMM runs at 2666 MHz with CL19 timing and 1.20 V operation. It adds error-correcting code protection and unbuffered signal processing to platforms that require data integrity without registered buffering.

Fits 288-pin DDR4 slots

The single-rank 1Rx8 organisation reduces electrical load on the memory controller, allowing multiple modules to populate available slots. Builders needing more than 16 GB can add further sticks without exceeding typical per-channel rank limits.

Sustained 2666 MHz throughput with ECC active

Under continuous workloads such as rendering or virtualisation the module maintains rated speed while correcting single-bit errors on the fly. The unbuffered design keeps latency low at CL19, so throughput scales predictably with each added module.

Questions about this item

How does the 1.20V voltage affect sustained performance?

The module operates at 1.20V, which is the standard DDR4 voltage, keeping power draw and heat low during continuous workloads.

What noise or heat should I expect when this DIMM runs all day?

As a passive component without a fan, the 288-pin DDR4 module produces no audible noise and minimal heat at its rated 1.20V.

Does my system need a 288-pin DDR4 slot that supports ECC and unbuffered memory?

Yes, the module requires a 288-pin DDR4 DIMM slot on a motherboard or workstation that accepts unbuffered ECC memory.
