8GB DDR4 SO-DIMM for Laptop Upgrades

This 8GB DDR4 SO-DIMM module is designed for laptop memory upgrades. It suits users who need to add capacity to a compatible notebook. The single-rank layout works with standard consumer platforms. Buyers who require ECC error correction or desktop DIMM form factors cannot use this module.

2666MHz PC4-21300 Speed Rating

The module operates at 2666MHz with a PC4-21300 bus rating and CL19 latency. This speed rating is the single specification that determines whether the part matches the system's memory controller requirements. Verify the laptop's supported memory speed before purchase.

Standard 1.2V Operation and Low Heat

Running at 1.2V, the module draws minimal power and produces little heat during normal use. The SO-DIMM form factor has no moving parts, so it adds no audible noise. Thermal output stays low enough for typical laptop cooling solutions.

Questions about this item

How does the 2666 MHz speed perform once installed in a laptop?

The module runs at 2666 MHz DDR4, delivering PC4-21300 bandwidth when the system supports it; actual throughput depends on the laptop's memory controller.

What does the PC4-21300 designation mean for compatibility?

PC4-21300 identifies the DDR4 2666 MT/s data rate on a 260-pin SO-DIMM; the laptop must accept DDR4 SO-DIMMs at that speed.

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

The 260-pin SO-DIMM form factor matches standard DDR4 laptop slots; verify your device uses DDR4 SO-DIMM memory before installing.
