64 GB DDR5 SODIMM kit

This kit contains four 16 GB DDR5 SODIMM modules rated at 4400 MHz with CAS latency 40. It is built for laptops or small-form-factor systems that accept 288-pin unbuffered non-ECC memory. The total capacity of 64 GB suits users who run virtual machines, large datasets or memory-intensive creative workloads on compatible platforms.

Matched 2Rx8 modules at 1.1 V

All four sticks share the same 2Rx8 organisation and 1.1 V operating voltage, so the memory controller sees a uniform electrical load. The supplier notes that mixing different module brands forces the system to run at the slowest installed speed, therefore this matched set avoids that bottleneck. A 64-bit operating system is required to address the full capacity.

Straightforward SODIMM installation

Each module fits a standard 288-pin SODIMM slot; no tools beyond a screwdriver for the chassis are needed. The most common issue is seating the module fully until the side clips click, otherwise the system will not POST. Because the kit is sold as a matched 4-piece set, installing all four together avoids the timing mismatches that can occur when adding single sticks later.

Questions about this item

Will the 2Rx8 DDR5 SODIMM modules need any firmware updates or replacement after extended use?

The modules carry a limited lifetime warranty against manufacturing defects from Computer Memory Solutions. No firmware updates are required for standard operation.

What timing parameter limits sustained throughput on these CL40 DDR5 4400MHz sticks?

The CAS latency of 40 cycles and the full timing string of 40-40-40-96 set the baseline latency floor during continuous workloads.

How much heat and power do the 1.1V DDR5 4400MHz SODIMMs produce when running all day?

Each module operates at 1.1V, the standard DDR5 voltage, keeping power draw and thermal output low for typical laptop or compact system cooling.
