Corsair Vengeance 8GB DDR4-2400 CL16 Laptop Memory SO-DIMM, 1.2V, Black, Non-ECC, PC4-19200, 260-pin

The Corsair Vengeance CMSX8GX4M1A2400C16 is a 8GB 260-pin DDR4 SO-DIMM for laptops and mini PCs rated at 2400 MT/s with CL16 latency at 1.2V, for DDR4 laptops, mini PCs and all-in-ones that take SO-DIMM memory.

It comes as one 8GB module, giving 8GB in total and up to 19.2 GB/s of peak bandwidth per module (PC4-19200). Adding or replacing a SO-DIMM is usually the simplest upgrade a laptop can get: more capacity means fewer slowdowns with many browser tabs, Office files and video calls open together.

Typical uses: upgrading an office or student laptop that struggles with Windows 11, Teams and many browser tabs, replacing a failed module, or populating a mini PC used as a small server or media box.

• 1 × 8GB DDR4 SO-DIMM module
• Manufacturer packaging — memory installs tool-free into the slot, no cables or drivers needed

• It is a standard JEDEC module: the system reads its settings automatically and runs it at 2400 MT/s CL16 if the platform supports that speed — no BIOS tuning. On a platform limited to a lower speed it simply runs slower, which is normal.
• A single module runs in single-channel mode. For dual-channel bandwidth (noticeably better in games and with integrated graphics) pair it with a second identical module — buying a matched kit is the safer route.
• 8GB covers browsing, e-mail and Office; for gaming, heavy multitasking or many browser tabs, 16GB is the practical minimum today.
• Mixing it with a different existing module usually works at the speed of the slower one; for guaranteed dual-channel behaviour replace both modules with an identical pair.
• Installation takes a few minutes: power off, unplug the charger (and the battery if it is removable), open the memory cover or base panel, insert the module at an angle into the slot and press it down until both side clips lock.
• After installation, Windows Task Manager (Performance → Memory) shows the total capacity, the speed in MT/s and how many slots are used — a quick way to confirm everything is detected.

• DDR5 or DDR3 laptops — the notch is in a different position
• Desktop motherboards (they take full-size DIMMs)
• Laptops with soldered memory and no free SO-DIMM slot, including Apple MacBooks
