  • Dual-channel kit boosts bandwidth with 32GB at 5600MHz
  • XMP 3.0 and EXPO profiles enable one-click overclocking

Crucial Pro DDR5 5600 32GB Kit

This Crucial Pro kit delivers 32GB of DDR5 memory in a matched pair of 16GB modules. It runs at 5600MHz with a CAS Latency of 46 and operates at 1.10V. The kit targets desktop builders using 12th or 13th Gen Intel Core or AMD Ryzen 7000 Series processors who want a straightforward dual-channel upgrade.

Upgrade From DDR5 4800 or 5200

The modules downclock automatically for systems limited to 4800MT/s or 5200MT/s, so they work in older DDR5 boards without manual tuning. Enabling the XMP 3.0 or EXPO profile restores the rated 5600MT/s speed when the platform supports it. The jump is worth it when the CPU and motherboard both validate 5600MT/s operation.

Simple UDIMM Installation

Each stick is a standard 288-pin UDIMM with a black heat spreader and no lighting, so it fits most desktop slots without clearance surprises. The XMP 3.0 and EXPO profiles load the correct frequency and timings in one BIOS step. The usual pitfall is leaving the profile disabled, which leaves the memory running at the board default speed instead of 5600MT/s.

Questions about this item

Does this 288-pin DDR5 UDIMM kit fit a standard desktop motherboard slot?

Yes, the two 16 GB modules use the standard 288-pin DDR5 UDIMM form factor and will seat in any desktop board with DDR5 slots.

How do I enable the rated 5600 MT/s speed — XMP 3.0 or EXPO — and what step is often missed?

Enter the BIOS, turn on Intel XMP 3.0 or AMD EXPO for the kit, save and reboot; the step often missed is confirming the profile actually applied after the restart.

Will the black heat spreaders ever need replacement or extra cooling?

The spreaders are fixed and require no replacement; normal case airflow is sufficient — no additional cooling is needed.
