CT4G4DFS8266 Crucial 1x4GB DDR4 UDIMM RAM

Enterprise DDR4 UDIMM Memory Upgrade featuring JEDEC-Compliant 2666MT/s Operation with the CT4G4DFS8266

The CT4G4DFS8266 is a Crucial 4GB DDR4 UDIMM designed for desktop and workstation platforms that require unbuffered, non-ECC DDR4 memory in standard 288-pin UDIMM slots. In systems where CPU memory controllers expect UDIMM signalling, the CT4G4DFS8266 provides a straightforward capacity and bandwidth uplift while maintaining JEDEC-aligned behaviour for predictable training and stable boot profiles.

Built around DDR4-2666 operation at 1.2V, the CT4G4DFS8266 supports balanced memory-channel utilisation on mainstream CPU platforms, aligning with PCIe-based I/O expansion by reducing contention during mixed compute and I/O bursts. Its single-rank x8 organisation is well-suited for common desktop memory topologies, helping integrators tune performance consistency for OS, hypervisor labs, and light service roles. As non-ECC UDIMM memory, CT4G4DFS8266 is intended for non-mission-critical environments where platform validation focuses on compatibility and deterministic timings rather than server-class error correction.

Why Choose the CT4G4DFS8266?

The CT4G4DFS8266 offers an efficient density-to-cost step for standard UDIMM deployments, enabling fast remediation of memory pressure without changing platform architecture. For IT teams standardising images across developer workstations or lab nodes, CT4G4DFS8266 supports scalable rollouts with consistent electrical characteristics, predictable JEDEC timings, and low-profile physical fit for compact chassis and constrained airflow paths.

Crucial engineering emphasises component-level qualification, conservative operating margins, and adherence to modern data-centre and enterprise desktop standards, supporting dependable lifecycle planning and repeatable integration across validated DDR4 UDIMM platforms.

Key Applications:

• Workstation memory upgrades
• Desktop virtualisation labs
• OS and application responsiveness improvements
• Test and staging environments
