2-power 2P-KVR26N19S6/4 - 4 GB - 1 x 4 GB - DDR4 - 2666 MHz

For desktop builds that demand stable, no-frills performance, this 4 GB DDR4 module from 2-POWER delivers the exact frequency and latency profile needed for mainstream computing. Unlike generic value RAM with loose timings, it runs at a true 2666 MHz with CL19 latency, ensuring predictable behaviour in office PCs, thin clients, and compact home servers. The single-rank, unbuffered design reduces electrical load on the memory controller, which can improve compatibility with budget motherboards and older chipsets. If you are upgrading from DDR3 or replacing a failed stick, this module offers a straightforward path to modern DDR4 without overspending on capacity you may not need.

Highlights

• 4 GB DDR4 SDRAM in a single module for easy installation.
• Runs at 2666 MHz (PC4-21300) with CL19 latency for balanced performance.
• 288-pin UDIMM form factor for standard desktop motherboards.
• Low 1.2 V operating voltage reduces heat and power draw.
• Non-ECC, unbuffered design suits consumer and business desktops.
• Single-rank configuration helps maintain signal integrity on many boards.

In daily use

This module is ideal for systems that need a reliable memory upgrade without chasing extreme overclocks. It handles everyday workloads—web browsing, document editing, spreadsheet work, and light multitasking—with ease. The 2666 MHz speed is a sweet spot for DDR4 platforms, offering a noticeable improvement over 2133 MHz or 2400 MHz modules in memory-sensitive tasks. Because it is unbuffered and non-ECC, it is compatible with a wide range of Intel and AMD desktop platforms, from older 6th-generation Core processors to current budget chipsets. The single-rank layout can also be beneficial when populating all four DIMM slots on boards that struggle with dual-rank modules at higher speeds.
