32 GB DDR4 2666 ECC UDIMM

This 32 GB DDR4 2666 module delivers error-correcting code memory for desktop PCs, workstations, servers and NAS systems. It runs at PC4-21300 with CL19 latency and 1.2 V operation. The unbuffered 288-pin design fits standard DDR4 DIMM slots.

JEDEC standard unbuffered DIMM

The module follows JEDEC specifications and is ROHS compliant for a warranty-safe upgrade. Its 2Rx8 organisation and black PCB install directly into 288-pin DDR4 slots without a heat spreader. Backward compatibility with 2133 MHz and 2400 MHz systems allows flexible deployment.

Low voltage ECC thermals

Operating at 1.2 V keeps power draw and heat output modest during continuous workloads. The absence of a heat spreader relies on case airflow for cooling, which is typical for unbuffered ECC DIMMs in server and NAS chassis. Silent operation is assured because no active cooling is required.

Perguntas sobre este artigo

Does the DDR4 2666 PC4-21300 module run at CL19 or a tighter latency?

It runs at CL19 as specified. The JEDEC-standard timing is fixed at that value for this speed grade.

Will the 288-pin unbuffered DIMM fit a standard desktop motherboard slot?

Yes. The 288-pin UDIMM form factor matches the standard DDR4 desktop slot used in workstations, servers and NAS systems.

How is the module installed and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click, then verify in BIOS that the speed reads 2666 MHz and ECC is enabled.
