Kingston Technology Corp. KVR21N15D8/8 8GB DDR4 2133 CL15 desktop RAM

Kingston ValueRAM 8GB DDR4 2133

This 8 GB unbuffered DDR4 module runs at 2133 MT/s with CL15 latency and 1.20 V operation. It targets desktop builders who need standard JEDEC memory for a new system or a straightforward upgrade. The single stick adds 8 GB of capacity without requiring XMP configuration or overclocking headroom.

Build quality and daily handling

Kingston assembles the module with screened DRAM chips and validates each stick under its internal qualification programme. The green PCB carries a standard 288-pin DIMM edge connector that seats in any desktop DDR4 slot keyed for 1.2 V signalling. No heat-spreader or LED lighting is fitted, so the module fits under low-profile CPU coolers and inside compact chassis without clearance issues.

Practical limits of DDR4 2133

At 2133 MT/s the module delivers up to 17 GB/s of theoretical bandwidth per channel, which matches the base JEDEC speed for DDR4. The 1.2 V supply reduces power draw by roughly 40 % compared with DDR3 at equivalent capacity. Systems that only support higher JEDEC bins will still run this memory, but at the platform's lowest common speed. Builders who need ECC, registered signalling or speeds above 2133 MT/s should select a different module.
