16GB dual-channel DDR5 laptop kit

This 16GB kit contains two 8GB DDR5 SO-DIMMs rated at 5600 MT/s with CL46 latency. The modules run at 1.10V and use the standard 262-pin form factor for modern laptops. They are sold as a matched pair for dual-channel operation.

No heat spreader or extra software included

The sticks are unbuffered, non-ECC and ship without a heat spreader or bundled utilities. Installation simply adds the rated speed and capacity to a compatible slot. No additional drivers or configuration tools are supplied in the package.

Suits 12th & 13th Gen Intel Core

The kit is validated for 12th and 13th Gen Intel Core and AMD Ryzen 6000 series notebooks. Buyers needing ECC error correction, registered modules, higher capacities per stick or a different pin count should look at other memory lines.

Questions about this item

Will the modules need a heat spreader added later for sustained loads?

The kit ships without a heat spreader; DDR5 SO-DIMMs run at 1.10 V and rely on the laptop's internal airflow, so no aftermarket spreader is required.

What latency ceiling appears first during extended heavy workloads?

CAS latency is fixed at CL46; under sustained use the memory controller cannot push timings tighter, so CL46 is the limiting factor.

How much extra heat or power draw should I expect when the RAM runs all day?

Operating at 1.10 V with no heat spreader keeps thermal output low; the dual-channel kit draws only the standard DDR5 SO-DIMM power budget.
