Corsair Vengeance SODIMM CMSX16GX5M1A5600C48

CL48 at 5600MHz gives roughly 17.1ns true latency, the loosest timing figure of any product on this site, though this figure isn't directly comparable to the desktop kits elsewhere in this family. Laptop DDR5 SO-DIMM generally runs looser timings and lower voltage than desktop DIMMs by design, prioritising power efficiency over the tightest possible latency, which matters far more on a battery-powered device than on a plugged-in desktop.

This is the critical spec on this page. SO-DIMM only fits laptops, mini-PCs and other small form factor systems that use SO-DIMM memory slots, and only if those slots are user-accessible rather than soldered. Before buying, confirm two things specifically: that the target device uses SO-DIMM (not soldered LPDDR5, which looks similar in marketing but cannot be upgraded at all) and that it supports DDR5 SO-DIMM specifically, since DDR4 and DDR5 SO-DIMM are not interchangeable and use different notch positions.

Intel XMP 3.0 is supported for reaching the rated 5600MHz; AMD EXPO support isn't listed for this SODIMM line the way it is across Corsair's desktop DDR5 kits, so confirm the target laptop's own memory profile support before assuming EXPO will apply.

This ships as a single 16GB module, not a matched pair. Most laptops with two SO-DIMM slots run in dual-channel when both slots are populated with matching modules, so check whether the target device already has memory installed in the second slot, and whether that existing module matches this one closely enough to run cleanly in dual-channel, before assuming this single module alone gets you the best available performance from the platform.

No heat spreader; SO-DIMM modules for laptops are typically bare PCBs given the tight internal clearance most laptops and mini-PCs are built around. Finished in black, matching Corsair's desktop DDR5 branding, though the physical design is entirely different hardware built for a different form factor.

Most laptops don't expose a full desktop-style BIOS or XMP toggle the way desktop motherboards do; on systems that do support manual profile selection, enabling XMP 3.0 in firmware settings should apply the rated 5600MHz. On many laptops, the system simply reads the module's XMP profile automatically at the rated speed with no manual step required, or the module runs at its JEDEC baseline if the platform doesn't support XMP over SO-DIMM at all. Confirm the target laptop's memory support before assuming full rated speed will apply.

This SO-DIMM module has no direct comparison within Corsair's desktop DDR5 lineup covered elsewhere on this site; the two form factors serve entirely different systems. Within Corsair's own SO-DIMM range, dual-module 2x16GB SO-DIMM kits exist at similar and higher speeds for laptops with two accessible slots wanting a matched dual-channel pair rather than a single module.

Laptop and mini-PC owners with an accessible, empty DDR5 SO-DIMM slot. A straightforward capacity upgrade for systems that support it.

Buyers replacing or supplementing existing laptop memory. Check compatibility with any existing installed module before buying.

Not for desktop builds. This will not physically fit a standard desktop motherboard; the desktop-DIMM kits covered elsewhere on this site are the correct category for that.

Not for laptops with soldered memory. Confirm the target device has a genuinely upgradeable SO-DIMM slot before buying; many modern thin-and-light laptops do not.
