Corsair VENGEANCE 64GB (2x32GB) DDR5-5600 CL48 SO-DIMM Laptop Memory Kit for Intel and AMD Laptops

The Corsair VENGEANCE CMSX64GX5M2A5600C48 is a 64GB (2x32GB) DDR5-5600 CL48 laptop SO-DIMM memory kit for laptops, small-form-factor PCs and Intel NUC kits with DDR5 SO-DIMM slots that need 64GB. It ships as a matched set of 2 x 32GB modules, tested together by Corsair, so every module runs the same timings in the same system.

It runs at its rated setting, stored in its SPD (DDR5-5600 CL48, 1.1V), with no BIOS changes. Because the SPD itself is programmed at 5600 MT/s, compatible systems use the full speed automatically — there is no profile to enable.

• 2 x 32GB DDR5 SO-DIMM modules (64GB (2x32GB) total)
• Retail packaging from Corsair
• No tools are included — a small screwdriver is usually needed to open the laptop base

• Install both modules together — two SO-DIMMs run in dual channel, which matters a lot for laptops with integrated graphics.
• Replace the existing memory rather than mixing: remove the factory modules and fit this matched pair.
• If the system runs the memory slower than 5600 MT/s, that is the laptop’s own limit — many platforms cap SO-DIMM speed, and the modules simply follow.
• 64GB suits mobile workstations used for virtual machines, large photo/video projects, data analysis and local development.
• The first boot after a memory change can take noticeably longer while the system trains the new modules.

• Desktop motherboards — these are 262-pin SO-DIMMs, not 288-pin desktop DIMMs.
• DDR4 or DDR5 LPDDR laptops — DDR4 SO-DIMM slots are keyed differently and LPDDR5/LPDDR5X memory is soldered, not upgradeable.
• Laptops with only one SO-DIMM slot or a 32GB/48GB maximum — you would not get the full 64GB.
• Apple Silicon Macs and most ultrabooks — their memory is integrated and cannot be replaced.
