2-power 2P-CT16G4SFRA32A - 16 GB - 1 x 16 GB - DDR4 - 3200 MHz

Laptops with 8 GB of RAM start to choke when you've got a browser with twenty tabs, a video call, and a code editor open at once. The 2-power 2P-CT16G4SFRA32A is a 16 GB DDR4 SODIMM module running at 3200 MHz that gives your notebook the breathing room it needs to keep everything fluid without constant disk swapping.

Key specifications

• Capacity: 16 GB (1 x 16 GB module)
• Type: DDR4 SDRAM, 260-pin SODIMM
• Speed: 3200 MHz (PC4-25600)
• CAS latency: CL22
• Voltage: 1.2 V
• Error correction: Non-ECC, unbuffered
• Rank: Single rank (1Rx8)
• Form factor: SODIMM for laptops and small form factor PCs

Why it's a smart upgrade

Jumping from 8 GB to 16 GB is the single most noticeable performance boost you can give a modern laptop. This module runs at the 3200 MHz sweet spot for current platforms, so it works without fiddling with BIOS settings. The standard 1.2 V operating voltage keeps heat and power draw low, which means your battery lasts longer than with older, thirstier memory.

Who it's for

• Anyone whose laptop stutters when multiple apps are open
• Users who want to enable dual-channel by adding a second module
• Those replacing a dead SODIMM in a notebook or mini PC
• People editing photos, compiling code, or crunching data on the move

Installation tips

Before you buy, check your laptop's maximum supported memory speed and capacity – most modern notebooks handle 3200 MHz fine, but older ones might cap lower. The module is non-ECC and unbuffered, which is exactly what consumer laptops expect. It's single-rank, so it's compatible with a wide range of OEM systems. Installing it is usually a matter of opening the bottom panel, slotting the module in at an angle, and pressing down until it clicks.

Pro tip: if your laptop has two SODIMM slots and you're currently running one 8 GB stick, adding this 16 GB module will give you 24 GB total, but it will run in flex mode (partly dual-channel). For the best performance, pair two identical modules – but even a single 16 GB stick will feel like a massive upgrade over 8 GB.
