Notebook memory DDR5 SODIMM 64GB(1*64)/5600 CL46

The Crucial CT64G56C46S5 is a 64 GB unbuffered SO-DIMM memory module in DDR5 form factor, operating at 5600 MHz with CL46 latency and 1.1 V voltage. It is intended for systems that support 262-pin SO-DIMM DDR5 modules and provides a large-capacity memory upgrade for laptops and small form-factor PCs that accept DDR5 SO-DIMM.

Advantages

This DDR5 64 GB module offers high capacity and increased memory bandwidth compared with previous-generation modules, while operating at a low 1.1 V supply. The 5600 MHz data rate and CL46 timing balance throughput and stability for memory-intensive applications. As an unregistered (unbuffered) SO-DIMM, it is compatible with consumer and mobile platforms that require standard SO-DIMM DDR5 modules.

Suitable for

• Upgrading laptop memory for heavy multitasking
• Mobile workstations and compact PCs used for content creation or video editing
• Systems running virtual machines or memory‑hungry professional applications

Key specifications

• Memory type: DDR5 SO-DIMM (unregistered/unbuffered)
• Capacity: 64 GB
• Data rate: 5600 MHz
• CAS latency: CL46
• Voltage: 1.1 V
• Pin count: 262-pin SO-DIMM

How to use

Power off the system and disconnect it from mains. Open the laptop or small-form-factor PC according to the manufacturer instructions, locate the SO-DIMM slot, and insert the module at an angle until the retention clips engage. Ensure the module is fully seated and the clips lock in place, then reassemble the device and power it on. Check system BIOS/UEFI to confirm the module is recognized and that memory frequency and timings are set as expected.

Recommendations

Install this 64 GB DDR5 SO-DIMM in systems that explicitly support DDR5 262-pin SO-DIMM modules. For dual-channel operation and optimal performance, pair modules in matched capacities and specifications where the platform supports it. Consult the system or motherboard documentation for supported memory speeds and maximum capacity limits before installation.
