4GB DDR4 2133MHz Laptop SODIMM

This 4GB DDR4 2133MHz module fits 260-pin SODIMM slots in laptops, notebooks and all-in-one systems. It runs at CL15 latency with a standard 1.2V supply and uses a 1Rx16 Samsung-based layout. The stick is non-ECC and unbuffered, matching mainstream consumer platforms. Buyers who need more than 4GB of capacity or who require ECC error correction for workstation tasks should look elsewhere.

DDR4 2133MHz PC4-17000 speed limit

The DDR4 2133MHz interface caps peak bandwidth at the PC4-17000 rate, so systems that support faster DDR4 will clock this module down to 2133MHz. Mixing it with higher-speed sticks forces the whole memory subsystem to run at the lowest common speed. The CL15 timing is fixed for this speed grade and cannot be tightened without exceeding the rated specification.

Simple SODIMM insertion, verify slot count first

Installation requires opening the laptop's memory compartment, aligning the 260-pin key and pressing the module until the side clips latch. The most common issue is a slot-count mismatch — some ultra-thin models have only one socket soldered to the board, leaving no room for an upgrade. Always confirm the number of available SODIMM slots and the maximum supported capacity in the system manual before purchase.

商品問答

Should I choose this 4 GB module or look for a different capacity?

This listing is a single 4 GB DDR4 2133 MHz SODIMM. Check your laptop’s maximum supported memory and free slots to decide whether one 4 GB stick is enough or if you need a larger kit.

What does the 2133 MHz rating mean for everyday use?

The module runs at 2133 MHz with CL15 latency, delivering PC4-17000 bandwidth. In a compatible system this speed handles web browsing, office apps and light multitasking smoothly.

Will the 260-pin DDR4 SO-DIMM fit my laptop’s memory slot?

Yes, it uses the standard 260-pin DDR4 SO-DIMM form factor at 1.2 V. Verify your device accepts DDR4 SO-DIMMs and has an available slot before installing.
