CT2K4G4DFS8266 Crucial 2x4GB DDR4 UDIMM RAM

High-Performance DDR4 UDIMM Memory Upgrade Kit for Compatibility-Focused Deployments with the CT2K4G4DFS8266

The CT2K4G4DFS8266 is a Crucial DDR4 UDIMM kit designed to stabilise and extend the service life of desktop and workstation platforms that rely on standard JEDEC profiles. Supplied as an 8GB (2x4GB) configuration, it targets systems where predictable boot behaviour and broad BIOS compatibility matter more than tuning features.

CT2K4G4DFS8266 operates at 2666MT/s with CL19 timings on a 64-bit, single-rank x8 organisation, providing a balanced latency-throughput profile for mainstream CPU platforms that expose DDR4 UDIMM channels. As a non-ECC, unbuffered 288-pin design, it is optimised for standard memory controllers found in entry and legacy enterprise endpoints, lab benches, and lightweight workstations. The 1.2V operating point supports power-conscious builds, while low-profile module height improves mechanical clearance in compact chassis and dense test rigs. This makes CT2K4G4DFS8266 well-suited to mixed PCIe expansion environments where GPU, NIC, or storage add-in cards occupy airflow and space, and where reliable memory training is essential for repeatable deployments.

Why Choose the CT2K4G4DFS8266?

The CT2K4G4DFS8266 provides a controlled, standards-aligned path to restore memory capacity and bandwidth without introducing XMP dependencies or overclocking variables. For fleets of heterogeneous DDR4 UDIMM systems, CT2K4G4DFS8266 supports a consistent upgrade approach that simplifies validation, reduces configuration drift, and maintains stable density-to-performance for productivity and light content workflows.

Crucial applies a qualification-driven engineering approach focused on long-term reliability, traceable component selection, and adherence to modern platform interoperability expectations, enabling predictable operation in business-critical environments.

Key Applications:

• Desktop and workstation memory upgrades
• Legacy DDR4 UDIMM platform refresh
• Lab and bench systems requiring JEDEC-only operation
• General productivity and office endpoints
• Light content creation workstations
