Kit composition and fit

This kit contains two 4GB DDR4 DIMMs for a total of 8GB. The modules are 288-pin unbuffered non-ECC memory designed for desktop systems that accept standard DDR4 DIMMs. Each stick uses a 2Rx8 organisation and operates at 1.2V.

Decisive specification

The rated speed is DDR4 2666 (PC4 21300) with CL19 timings of 19-19-19. If the platform or existing memory runs at a lower data rate, all installed modules will operate at that slower speed. Matching the rated speed and latency avoids down-clocking the whole array.

Capacity and headroom

Eight gigabytes handles everyday multitasking, office suites and light content creation. A 64-bit operating system is required to address more than 4GB. Demanding workloads such as heavy virtualisation, large media projects or modern gaming at high settings will exceed this capacity.

Questions sur cet article

Will these 2666 MHz modules run at that speed on my board?

They are rated for DDR4-2666 and will operate at that frequency if the CPU and motherboard support it; otherwise they downshift to the highest speed the platform allows.

What does the PC4 21300 label on these DIMMs indicate?

It is the industry name for DDR4-2666 memory, showing the peak transfer rate class for this speed grade.

Do these 288-pin DIMMs fit a standard desktop DDR4 slot?

Yes, they use the 288-pin DDR4 DIMM form factor used by current desktop motherboards.
