2-power 2P-CT51264BF1339 - 4 GB - 1 x 4 GB - DDR3 - 1333 MHz

4 GB DDR3 at 1333 MHz – that's the sweet spot for reviving an older desktop without spending a fortune. This 2-power 2P-CT51264BF1339 module is a straight drop-in for countless office and home PCs that still run on DDR3.

What you get

• 4 GB capacity, single stick (1 x 4 GB)
• DDR3 SDRAM, 1333 MHz (PC3-10600)
• 240-pin DIMM, non-ECC, unbuffered
• 1.5 V standard voltage
• Configuration: 512M x 64

Why this module makes sense

If your desktop feels sluggish with a few tabs open or lags when switching between documents, this stick gives it a second wind. It's built for stability, not overclocking – exactly what you need for everyday work. The unbuffered design keeps latency low, and the 1.5 V operation means it won't stress your power supply.

Who it's for

• Users upgrading an older desktop to extend its life
• Building a budget office PC or repairing a system
• Multitasking with web browsers, email, and office suites

Installation in a nutshell

Turn off the PC, open the case, and locate the DIMM slots. Align the notch on the module with the slot, press down firmly until the clips click. That's it. But first, check your motherboard supports DDR3 and how many GB it can handle per slot – most older boards top out at 4 GB per slot.

Tip: If you're adding this to an existing stick, try to match speed and voltage for best compatibility. And always handle the module by its edges – static can kill it.
