UD138 16 GB DDR4 module

This is a 16 GB DDR4 UDIMM built for desktop systems that need a straightforward memory upgrade. It targets content creators, gamers and everyday users who want reliable capacity without extra complexity. The unbuffered non-ECC design fits standard consumer motherboards.

2666 MHz CL19 speed rating

The module runs at DDR4 2666 (PC4 21300) with a CAS latency of 19 at 1.2 V. That single speed and timing combination determines whether the stick matches your platform's supported data rate and latency window.

16 GB capacity with 31.3 mm height

Sixteen gigabytes handles typical multitasking, mainstream gaming and creative workloads comfortably. The low 31.3 mm profile clears most CPU coolers, while the 20 % power saving versus DDR3 reduces thermal load.

Questions about this item

Will this 16 GB DDR4 module fit my motherboard's 288-pin slots?

The UD138 is a standard 288-pin unbuffered non-ECC UDIMM, so it installs in any desktop board with DDR4 slots.

What does CL19 at 2666 MHz mean for everyday use?

CL19 is the CAS latency cycle count; at 2666 MHz it delivers typical desktop responsiveness for office work, browsing and light gaming.

Do I need to change any voltage settings in BIOS?

The module runs at the JEDEC-standard 1.2 V, so most boards will configure it automatically without manual adjustment.
