Capacity and kit layout

This 32 GB kit contains two 16 GB unbuffered DIMMs built for dual-channel desktop platforms. Each module runs at 2133 MHz with CL15 latency at 1.20 V. The 288-pin form factor fits standard DDR4 motherboard slots.

Upgrade path from older DDR4 modules

The kit replaces single-channel or lower-capacity DDR4 memory when a system needs more bandwidth and 32 GB total capacity. The jump is worthwhile when the board supports dual-channel operation and the workload benefits from the added capacity.

Sustained-load behaviour

Under continuous use the modules operate at the rated 1.20 V without exceeding the specified CL15 timing. Unbuffered signal processing and major-brand chips maintain stable throughput during extended sessions. Thermal output remains consistent with standard DDR4 DIMM operation.

Questions about this item

Will the 288-pin DIMM modules fit my motherboard's DDR4 slots?

These modules use the standard 288-pin DDR4 DIMM form factor and will fit any desktop motherboard slot designed for DDR4 memory.

Do I need to enable XMP or change BIOS voltage for the 1.20V CL15 speed?

The kit runs at its rated DDR4 2133 CL15 at the standard 1.20V without XMP; simply install the modules and the system will boot at those timings automatically.

Can I replace a single 16GB stick later or must I replace the pair?

The kit is sold as a matched dual-channel pair of 16GB modules; for optimal stability you should replace both sticks together rather than mixing a single new module with the existing one.
