RIMLANCE 4GB DDR4 2666 UDIMM

This single 4GB unbuffered DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. The 1Rx8 organisation fits standard desktop DIMM slots and uses major-brand chips for baseline stability. It adds entry-level capacity for everyday office or home systems.

Upgrade from 2GB or empty slots

Replacing a 2GB stick or populating a free slot doubles usable memory for light multitasking. The jump is worthwhile when the current system stutters with several browser tabs or office applications open. It restores headroom without requiring a full platform change.

Handles web browsing and document editing

The 4GB capacity comfortably runs a modern OS with typical productivity apps and a handful of browser tabs. It runs out when editing large media files, running virtual machines or keeping many heavy applications open simultaneously. Additional modules would be needed for those workloads.

Questions about this item

Does the 1Rx8 UDIMM need a 288-pin DDR4 slot?

Yes, it is a standard DDR4 UDIMM that fits a 288-pin desktop DIMM socket.

What is the correct way to seat the module so the CL19 timing works?
