Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • Faster data rates up to 2666 MT/s for responsive multitasking
  • Up to 32% more bandwidth improves throughput on DDR4 platforms
  • Up to 40% less power draw at 1.20V reduces system heat
  • CL19 19-19-19 timing delivers quicker burst access for sequential workloads
  • Unbuffered 288-pin design fits standard desktop DDR4 slots

8GB DDR4 2666 desktop module

This 8GB DDR4 2666 UDIMM targets mainstream desktop upgrades and replacement builds. It runs at 1.20V with CL19 timings and requires a 288-pin slot. Buyers who need ECC or registered memory cannot use this module.

Capacity and headroom

The 8GB capacity suits everyday office work, web browsing and light multitasking. Bandwidth increases of up to 32% over prior DDR4 speeds help sustained throughput. Demanding workloads such as heavy video editing or large virtual-machine sets will exhaust the 8GB limit.

Manufacturer highlights

Micron-backed engineering claims up to 40% lower power draw and faster burst access for improved sequential data throughput. The module is optimised for next-generation processors and platforms as DDR4 matures. No software or extra accessories are bundled.

Points forts

Questions sur cet article

Will this 8 GB module fit my desktop motherboard?

It uses the standard 288-pin DDR4 UDIMM form factor, so it installs in any desktop board with a DDR4 slot.

Can I run it at the rated 2666 MT/s without manual BIOS changes?

The module operates at 1.20 V with CL19 timings (19-19-19) and will run at its rated speed on any compatible DDR4 platform.

Does this stick support ECC error correction?

No, it is a non-ECC unbuffered module intended for standard consumer desktops.
