32GB Dual-Channel DDR4 Kit

This 32GB kit contains two 16GB DDR4 3200 modules rated at CL22 and 1.2V. It is built as a direct replacement for the Crucial CT2K16G4DFRA32A part and fits standard desktop DIMM slots.

Sustained Load Behaviour

JEDEC-standard timings keep latency predictable during long sessions rather than short bursts. The 1Rx8 organisation and unbuffered design deliver steady throughput for multitasking, large-file editing and NAS workloads without throttling.

Thermals Noise and Power

Operating at 1.2V without a heat spreader, the modules run cool and silent in typical desktop and workstation chassis. Backward compatibility with 2133, 2400, 2666 and 2933MHz systems means the kit draws only the power the platform requests.

Questions about this item

How much power does the 1.2V DDR4 3200 kit draw when the system runs all day?

Each 16GB module operates at the standard JEDEC 1.2 V, so the dual-channel kit stays within the normal DDR4 power envelope for continuous desktop or NAS workloads.

What must the motherboard provide for these 288-pin DIMMs to work?

A desktop board with DDR4 slots that accept 288-pin unbuffered non-ECC DIMMs and support the JEDEC 3200 MT/s speed at 1.2 V.

Will the 3200 CL22 sticks run stably alongside my older 2666 MHz modules?

Yes — the kit is backward compatible with 2133, 2400, 2666 and 2933 MHz speeds, so the system will simply run all populated slots at the highest common frequency.
