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.

商品問答

Is the single 4GB module the only capacity option for this model?

Yes, this specific RUD21300S6C4 module is supplied as a single 4GB stick with a 1Rx16 chip layout.

What does the 2666MHz rating mean for actual data throughput?

The module runs at DDR4 2666, delivering a PC4-21300 peak transfer rate of 21300 MB/s in a compatible system.

Does the 288-pin DDR4 interface limit the speed on older chipsets?

The 288-pin DDR4 UDIMM fits any desktop DDR4 slot; the memory controller will negotiate the highest common speed up to 2666MHz.
