2-power 2P-CT5811882 - 8 GB - 1 x 8 GB - DDR3L - 1600 MHz

8 GB DDR3L at 1600 MHz, single module, 204-pin SO-DIMM – that's the spec you need when a laptop starts choking on Chrome tabs or a repair bench needs a known-good stick. The 2-power 2P-CT5811882 is a low-voltage (1.35 V) module that slots into compatible notebooks and mini-PCs to give them a second wind.

Why this module works

• Low voltage means less heat and longer battery life – a real plus for portable use.
• Dual-rank design helps memory bandwidth, so everyday tasks feel snappier.
• Non-ECC, unbuffered – standard for most consumer and business laptops.

Who it's for

• Upgrading an older ultrabook or small-form-factor PC that takes DDR3L.
• Replacing a dead stick in a business notebook – quick fix, no fuss.
• Boosting performance for office suites, video calls, and light photo editing.

Key specs

• Capacity: 8 GB (1 x 8 GB)
• Type: DDR3L SDRAM, 1.35 V (also works in many 1.5 V slots)
• Speed: 1600 MHz (PC3-12800)
• Form factor: 204-pin SO-DIMM
• CAS latency: CL11
• Rank: Dual rank (2Rx8)
• ECC: Non-ECC, unbuffered

How to install

Power off, open the memory compartment, align the notch, push the module in at an angle, then press down until the clips lock. No tools needed. Always check your system's specs first – this is DDR3L, not DDR4.

Tip: If your laptop is from 2012–2016 and feels slow, a single 8 GB stick like this is often the cheapest meaningful upgrade. Pair it with an SSD if you haven't already – that combo transforms old machines.
