8 GB DDR4 2133 MHz SO-DIMM Laptop RAM Multi-Brand Refurbished

Description

The refurbished 8 GB DDR4 SO-DIMM RAM clocked at 2133 MHz (PC4-17000) is an essential replacement part and system upgrade for repair workshops, second-hand machine preparers, and corporate IT departments. Intended for the refurbishing and memory upgrade market, this multi-brand solution helps optimise the fluidity of laptops, mini-PCs (NUCs), and NAS servers running on Intel Core (6th to 8th generation) and AMD Ryzen Mobile processor architectures. It is designed for professionals looking to boost the overall performance of an IT fleet without impacting the economic equation of their intervention.

In terms of electronic architecture, this module is based on the DDR4 SDRAM Unbuffered Non-ECC standard operating at a reduced nominal voltage of 1.2 Volts. This low operating voltage helps reduce the laptop battery's overall energy consumption while limiting heat generation within the chassis. Equipped with a 64-bit data bus offering a theoretical bandwidth of 17 GB/s (17000 MB/s) with a CAS latency of CL15, the stick guarantees fast multitasking execution and increased responsiveness when loading business applications under Windows, Linux, or macOS. Sourced from original manufacturer batches (Samsung, SK Hynix, Micron), each refurbished part undergoes rigorous stress testing to validate the integrity of the memory matrix and communication tracks.

The mechanical assembly strictly complies with JEDEC specifications for the 260-pin SO-DIMM form factor. Its low profile of 30 mm ensures easy integration into the ultra-compact slots of ultrabooks. Thanks to the factory-programmed Serial Presence Detect (SPD) identification chip, the module is automatically recognised in Plug-and-Play by the motherboard BIOS/UEFI, which instantly adjusts voltages, frequencies, and timings as soon as the machine starts up.

Workshop Advice & Usage

Before any memory addition or replacement procedure on a laptop, be sure to disconnect the mains charger and unplug the internal battery to eliminate any residual voltage on the motherboard. Always handle the stick by its side edges to avoid any skin oil deposits on the NAND chips, and use an anti-static (ESD) wrist strap to protect the circuits against electrostatic discharges. During installation, insert the module into the SO-DIMM slot at a 30-degree angle until the gold connectors are fully engaged, then gently push the memory down towards the motherboard until the two side metal clips lock automatically. To benefit from Dual-Channel mode, pair this module with a second stick of equivalent capacity and frequency.
