4 GB DDR4 module for desktop PCs

The RIMLANCE RUD21300S6C4 is a single 4 GB unbuffered DIMM built for standard desktop motherboards. It targets users who need a basic capacity boost for everyday multitasking and office workloads. The module uses a 1Rx16 chip layout and runs at the JEDEC-standard 1.2 V.

DDR4-2666 CL19 speed ceiling

The stick operates at 2666 MT/s with a CAS latency of 19, matching the PC4-21300 data-rate ceiling defined by the DDR4 specification. Bandwidth and latency are fixed at these JEDEC values, so the module cannot exceed the standard 2666 MT/s transfer rate or tighten timings without platform support for manual overclocking.

Simple 288-pin insertion

Installation requires aligning the notch on the 288-pin edge connector with the motherboard slot and pressing until the retention clips click. The low 1.2 V voltage means no extra power cables are involved. The most common issue is a partially seated module that prevents the system from posting, which is resolved by re-seating the DIMM firmly.
