64GB DDR5 5600 laptop module

This Crucial CT64G56C46S5 module brings 64 GB of DDR5 memory to a laptop SO-DIMM slot. It runs at 5600 MT/s with CL46 latency and 1.10 V. The 262-pin unbuffered design drops straight into compatible notebooks for immediate capacity gains.

Suits single-slot upgrades needing maximum density

Builders who need two modules for dual-channel bandwidth should look elsewhere, as this is a single 64 GB stick. Systems limited to 4800 or 5200 MT/s will downclock the module automatically. Buyers requiring ECC error correction must choose a different part.

5600 MT/s speed with CL46 timing

The module operates at DDR5 5600 (PC5 44800) with a CAS latency of 46 cycles. This speed and latency combination determines whether the memory matches your platform's supported specification and performance target.

Questions about this item

Does my laptop need a DDR5 262-pin SO-DIMM slot to use this 64GB module?

Yes, the module is a 262-pin DDR5 SO-DIMM, so the laptop must provide a DDR5 SO-DIMM socket.

Will this 5600MHz stick run at a lower speed if my system only supports 5200MHz or 4800MHz DDR5?

The 5600MHz module can downclock to 5200MHz or 4800MHz when the platform requires it.

How can I confirm the RAM is running at 5600MHz with CL46 timing after installation?

Check the memory speed and CAS latency in BIOS or a tool such as CPU-Z; they should show 5600MHz and CL46.
