Desktop DDR5 Memory Upgrade

This Crucial CT16G56C46U5 module provides 16 GB of DDR5 memory in a single UDIMM form factor. It operates at 5600 MHz and can downshift to 5200 MHz or 4800 MHz for broader platform compatibility. The product is new and intended for desktop systems that accept DDR5 UDIMM modules.

Suitable for DDR5 Desktop Builds

This module suits builders adding capacity to a desktop board with DDR5 slots that support 5600, 5200 or 4800 MHz speeds. It is not for laptops or small-form-factor systems that require SODIMM modules, nor for platforms limited to earlier memory generations.

DDR5-5600 Speed Rating

The decisive specification is the DDR5-5600 bus speed with fallback to 5200 MHz and 4800 MHz. Verify that the motherboard and processor support this speed range before purchase.

Questions about this item

Does my motherboard need a DDR5 UDIMM slot for this 16 GB module to work?

Yes, the CT16G56C46U5 is a DDR5 UDIMM and requires a motherboard with a DDR5 UDIMM slot.

Will this 5600 MHz stick downclock automatically if I keep my older 4800 MHz DDR5 modules installed?

The module supports 5600, 5200 and 4800 MHz speeds and will run at the highest common speed supported by all installed memory.

How can I confirm the CT16G56C46U5 is running at 5600 MHz after installation?

Check the memory speed reported in your BIOS or a system-information tool such as CPU-Z; it should show 5600 MT/s when the platform supports that rate.
