16GB DDR4 module for desktop builds

This Crucial UDIMM delivers 16 GB of DDR4 memory at a tested 2666 MHz frequency. It is unbuffered, non-ECC and operates at a standard 1.2 V. The module is validated for AMD Ryzen platforms and carries an AMD EXPO profile for straightforward configuration.

Sustained operation at rated speed

Under continuous load the module maintains its specified 2666 MHz data rate with CL19 latency timings. The dual-rank x8 organisation supports stable throughput during extended sessions without exceeding the 1.2 V operating voltage.

DDR4 interface limits

The DDR4-2666 standard defines a maximum transfer rate of 21300 MB/s on a 288-pin DIMM. This module meets that ceiling at CL19, so further frequency gains would require a platform that supports higher DDR4 data rates.

Perguntas sobre este artigo

Does the 1.20V DDR4 module run hot or draw much power when the system is under load all day?

The stick operates at the standard DDR4 voltage of 1.20V, so heat output and power draw stay low even during extended sessions.

What must the motherboard provide for this 288-pin DIMM to work?

A desktop board with a DDR4 slot that accepts 288-pin unbuffered non-ECC modules at 2666 MHz.

Will this CL19 2666 MHz kit run stably alongside older DDR4 sticks I already have?

The motherboard will clock all modules to the slowest speed and loosest timings present, so mixing is possible but not guaranteed.
