SK Hynix 8 GB DDR4 SO-DIMM - 2666MHz - Laptop Memory (Refurbished)

Description

The SK Hynix 8 GB DDR4 2666MHz memory module is the ideal upgrade solution to optimise the responsiveness of your laptop, iMac, or Mini-PC. By doubling your RAM or replacing a slow module, you allow your system to run Windows 11 much more smoothly, reduce application loading times, and significantly improve multi-tab browsing. Manufactured by SK Hynix, a world leader in semiconductors, this HMA81GS6CJR8N-VK part ensures industrial-grade reliability identical to factory-installed components from Dell, HP, or Lenovo.

Technically, this module offers a bandwidth of 21.3 GB/s, ensuring fast data transfers between the processor and memory. Its low-power architecture (1.2V) is a major asset for mobile devices, as it preserves battery life while limiting internal heat dissipation. The 260-pin SO-DIMM format is the universal standard for modern laptops, offering simple and immediate installation without the need for technical adjustments in the BIOS.

This product is offered as a certified refurbished version. Each module has been rigorously tested on professional diagnostic benches to validate frequency stability and the total absence of memory errors. Choosing this Refurbished SK Hynix memory means opting for the performance of an original equipment component at an optimised price, while contributing to a more responsible consumption approach.

Workshop Advice & Usage

Adding 8 GB of RAM is the most cost-effective upgrade to extend a computer's lifespan by a few years. Recommended method: Turn off the device, remove the battery (or disconnect it), and handle the module by its side edges to avoid any static discharge on the black components. Technical note: This module is backwards compatible with systems supporting frequencies of 2400MHz or 2133MHz; it will automatically adjust to the speed dictated by the processor. To maximise performance (a 10 to 15% gain in system speed), try pairing this module with another identical 8 GB stick to enable "Dual Channel" mode.
