8GB DDR4 2666MHz Desktop Memory

This 8GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 288-pin DIMM form factor and unbuffered, non-ECC design. The kit suits desktop owners who need a straightforward capacity increase for everyday workloads.

Verify DDR4 DIMM slot and 2666MHz support

Before ordering, confirm your motherboard accepts DDR4 DIMMs and can run at 2666MHz. Check that the board supports unbuffered, non-ECC modules at 1.20V. Consult the system manual or vendor specification sheet to ensure the memory controller handles this speed and timing.

Replaces Kingston KVR26N19S8/8 and HP26D4U9S8ME-8

This module is a compatible equivalent for the Kingston KVR26N19S8/8 and HP26D4U9S8ME-8 parts. The upgrade makes sense when your system currently runs less than 8GB or uses slower DDR4, and the platform supports 2666MHz CL19 operation.

Questions about this item

What comes inside the package and what must be purchased separately?

The package contains one 8GB DDR4 2666MHz CL19 288-pin DIMM running at 1.20V. No extra cables or brackets are included; additional modules for dual-channel operation must be bought separately.

How do I decide between this single 8GB module and a larger capacity kit?

Choose this single 8GB stick when your board has a free slot and you only need a modest capacity increase; select a higher-capacity kit if your workload demands more than 8GB total or if you want matched modules for dual-channel performance.

What does the 2666MHz rating mean once the stick is installed?

The module will run at 2666MHz with CL19 timing at the standard 1.20V DDR4 voltage, delivering PC4-21300 bandwidth provided the motherboard supports that speed and the BIOS is set accordingly.
