64GB DDR4 3200 kit for notebooks

This 64GB kit contains two 32GB SO-DIMMs built to the DDR4 3200 (PC4 25600) specification. It targets laptop owners and system integrators who need the maximum capacity supported by a two-slot DDR4 platform. The modules are manufactured by Black Diamond Memory, a specialist with experience across enterprise servers, desktops and mobile devices.

DDR4 SO-DIMM speed and density ceiling

The DDR4 3200 standard sets the practical ceiling for both transfer rate and per-module density on 260-pin SO-DIMMs. Systems that only qualify lower speeds will clock the kit down automatically, so the rated 3200 MT/s is only reached when the platform and BIOS allow it. No higher DDR4 speed or larger module size exists in this form factor.

260-pin layout and broad validation

Each stick uses the standard 260-pin DDR4 SO-DIMM edge connector, so it fits any compatible slot without adapters. Black Diamond Memory validates the design against a large library of platform configurations, reducing the chance of POST failures during upgrades. The low-profile construction clears tight chassis spaces found in thin-and-light notebooks.
