Capacity and compatibility

This 48GB DDR5-5600 module is an unbuffered, non-ECC DIMM designed as a direct replacement for the Crucial CP2K48G56C46U5 kit. It fits standard 288-pin desktop slots and runs at the standard 1.10V voltage. The single-module layout lets you add 48GB of capacity without occupying multiple slots.

Sustained-load behaviour

Rated at 5600 MT/s with a CAS latency of 40, the module maintains its rated speed under continuous workloads rather than only in short bursts. Major-brand DRAM IC chips and full quality-assurance testing support stable throughput during extended rendering, compilation or virtualisation sessions. The 1.10V operation keeps power draw consistent over long periods.

Pre-order checklist

Verify that your motherboard and CPU officially support DDR5 at 5600 MT/s and can address a 48GB 2Rx8 unbuffered DIMM. Confirm the board has a free 288-pin slot and that the BIOS is updated to the latest version for high-capacity modules. Consult the system manual for correct seating and channel guidelines before installation.

Questions about this item

Will this single 48 GB DDR5-5600 module work in a motherboard with four DIMM slots?

Yes, it fits any standard 288-pin DDR5 desktop slot. Install it in the primary slot recommended by your motherboard manual for single-module operation.

My board lists PC5-44800 support — does the 46 CAS latency in the Crucial part number matter?

This module runs at CAS 40, which is tighter than the 46 figure in the Crucial reference. The motherboard will automatically use the module's programmed timings at 5600 MT/s.

Is any BIOS update or voltage tweak required to reach 5600 MT/s?

The module operates at the standard 1.1 V DDR5 voltage. Most current desktop platforms enable 5600 MT/s at default settings; check your motherboard's QVL for confirmed compatibility.
