What this kit is

The Crucial Pro 64GB kit contains two 32GB DDR5 modules rated at 5600MT/s with CL46 latency and a 1.10V operating voltage. It is an unbuffered dual-channel UDIMM kit with black heat spreaders and no LEDs, intended for desktop systems that accept DDR5 memory.

What to check before ordering

Your motherboard must support DDR5 UDIMMs and provide 288-pin slots. The kit runs at 5600MT/s via Intel XMP 3.0 or AMD EXPO profiles, and it will downclock to 5200MT/s or 4800MT/s if the platform only supports those speeds. Verify that your CPU and board enable the chosen profile in BIOS.

Who this suits and who should look elsewhere

This kit suits builders using 12th or 13th Gen Intel Core or Ryzen 7000 Series desktop CPUs who want 64GB of plug-and-play performance with XMP 3.0 and EXPO support. Users who need ECC error correction, registered modules, or speeds beyond 5600MT/s should consider other products.

Questions about this item

Will this kit run at its rated speed on a 12th Gen Intel Core processor?

Yes, the kit is validated for 12th and 13th Gen Intel Core desktop CPUs and supports Intel XMP 3.0 for automatic configuration to 5600MT/s.

Can I use this memory in a system that only supports DDR5 4800 or 5200?

The modules are downclock capable and will operate at 4800MT/s or 5200MT/s if the motherboard or CPU does not support the full 5600MT/s speed.

What do I need to enable the rated 5600MT/s speed?

A motherboard with DDR5 slots that supports Intel XMP 3.0 or AMD EXPO, plus a compatible 12th/13th Gen Intel Core or Ryzen 7000 series desktop CPU, will allow the profile to load at 1.10V.
