64GB DDR5 SODIMM kit for laptops and NAS

This kit provides 64GB of DDR5 memory across four 16GB modules. It targets owners of compatible laptops, all-in-one PCs and NAS devices who need more capacity for multitasking or larger workloads. The modules are unbuffered and non-ECC, matching the requirements of most consumer mobile platforms. Builders needing registered or error-correcting memory should look elsewhere.

262-pin JEDEC standard modules at 1.1V

Each stick follows the 262-pin SO-DIMM form factor and operates at the standard 1.1V DDR5 voltage. The lack of a heat spreader keeps the profile low for tight chassis clearances. JEDEC compliance and RoHS certification mean the kit meets industry baseline specifications for a warranty-safe upgrade. Installation is a straightforward DIY step on most supported systems.

CL40 latency at PC5-38400 4800MHz speed

The memory runs at 4800MHz with a CAS latency of CL40, delivering the standard DDR5-4800 data rate. This single timing figure determines whether the kit matches the maximum supported speed of a given platform. Systems limited to lower DDR5 frequencies will downclock the modules automatically.

Highlights

Questions about this item

What speed does the DDR5 4800 interface actually run at?

The modules operate at 4800 MT/s with CL40 timing, matching the JEDEC PC5-38400 standard.

Will these 262-pin SODIMMs fit my laptop's memory slots?

They require standard 262-pin DDR5 SO-DIMM slots; verify your system supports DDR5 SO-DIMM before purchase.

How do I install the four 16 GB modules correctly?

Power off, open the access panel, align each module's notch with the slot key, press firmly until the side clips click, then reassemble.
