SK hynix 8GB DDR4 2400MHz SODIMM

This SK hynix module adds 8GB of DDR4 memory to a compatible laptop. It runs at 2400MHz with CL17 latency and 1.20V operation. The unbuffered, non-ECC design suits mainstream notebook upgrades.

Check 260-pin DDR4 slot and voltage

Verify the notebook accepts 260-pin DDR4 SO-DIMM modules before ordering. The system must support 1.20V operation and PC4-19200 speed for correct function. Confirm an empty slot exists or plan to replace the existing stick.

Single-rank 260-pin build quality

The single-rank PCB uses 260 gold-plated edge contacts for reliable seating in the SODIMM socket. Low-profile height fits tight chassis clearance. Standard JEDEC pinout ensures straightforward installation without adapters.

Spurningar um þessa vöru

Does the HMA81GS6AFR8N-UH module come alone or as a kit, and is any extra hardware needed?

The listing describes a Dual Channel Kit, so two 8 GB modules are included. No extra brackets, cables or heat spreaders are required for a standard 260-pin SODIMM slot.

Should I pick the CL17 2400 MHz version or a different speed grade for my laptop?

Choose this CL17 2400 MHz kit when your laptop’s memory controller is rated for DDR4 2400; a higher-speed module would simply down-clock to 2400 MHz, while a lower-speed one would limit peak bandwidth.

What does the 2400 MHz rating mean once the kit is installed in a laptop?

The memory bus runs at 300 MHz clock with a 2400 MT/s data rate, delivering a PC4 19200 peak transfer rate; actual throughput depends on the CPU’s integrated memory controller and the workload’s access pattern.
