Single 4GB DDR4 module

This single 4GB DDR4 UDIMM runs at 2666MHz with PC4-21300 bandwidth. It targets DIY builders and cost-conscious gamers who need a basic capacity boost for everyday desktop tasks. The Silverline heatsink uses aircraft-grade aluminium for thermal management.

Straightforward UDIMM installation

The module fits any standard DDR4 desktop slot and is 100% tested for broad Intel and AMD motherboard compatibility. No extra software or firmware steps are required. Builders who need more than 4GB total capacity or multi-channel bandwidth should add matching modules.

Consistent JEDEC operation under load

Rated timings of 19-19-19-43 are maintained at the 2666MHz JEDEC specification during sustained workloads. The aluminium heatsink dissipates heat to keep performance stable over long sessions. Energy-efficient design limits power draw while meeting JEDEC standards.
