8GB DDR4 2133MHz desktop memory

This A-Tech module adds 8GB of DDR4 memory to a desktop system. It is built as a direct replacement for several Kingston part numbers including HX421C14FB/8 and KVR21N15/8. The stick uses a standard 288-pin DIMM form factor and runs at 1.20V.

DDR4 2133 PC4-17000 practical limits

The DDR4 2133 standard tops out at 2133 MT/s with a PC4-17000 bandwidth ceiling. This module operates at CL15 latency and 1.2V, so it cannot exceed the JEDEC base specification for this speed grade. Systems that only support lower DDR4 speeds will downclock the module automatically.

Upgrade from 4GB or 8GB CL16 modules

Replacing a single 4GB stick or a slower CL16 8GB module with this CL15 8GB unit raises total capacity and tightens latency. The jump is worthwhile when the motherboard and CPU memory controller both support DDR4 2133 at CL15, letting the system run at the rated timings without manual tuning.

Questions sur cet article

Should I choose the single 8GB stick or a 2x8GB kit for my desktop?

This listing is a single 8GB module; order two if your board supports dual-channel and you want 16GB total.

What does the 2133MHz speed actually deliver in everyday use?

It runs at the standard DDR4 2133 MT/s data rate, giving a peak bandwidth of 17 GB/s for typical desktop workloads.

Does the DDR4 288-pin interface limit the module to 2133MHz?

The 288-pin DIMM socket accepts faster DDR4 speeds, but this module is rated and tested at 2133MHz CL15.
