SK hynix HMA81GS6AFR8N-UH_UB 8GB DDR4 SO-DIMM 2400MHz CL17 1.2V laptop memory accessory

What this module adds to a laptop

This 8 GB DDR4 SO-DIMM upgrades a compatible notebook with a single 260-pin stick rated at 2400 MHz and CL17 latency. It is intended for owners who need extra capacity for everyday multitasking and standard productivity workloads. Buyers who want higher frequencies or lower latencies will need a different specification.

Thermals and power in daily use

The module runs at 1.2 V, keeping power draw low during typical office and browsing sessions. No active cooling is required and the stick produces no audible noise. Builders who need ECC error correction or registered buffering cannot use this non-ECC part.

Build and connector practicalities

The green PCB uses a standard 260-pin SO-DIMM edge connector that seats directly into the laptop memory slot. No cables, brackets or additional hardware are included in the package. Users who need a matched pair for dual-channel operation must purchase a second identical module separately.
