SK hynix HMA81GU6AFR8N-UH 8GB DDR4 2400MHz desktop RAM

8GB DDR4 2400MHz Desktop Module

This SK hynix DIMM provides 8GB of DDR4 memory at 2400MHz for desktop computers. The unbuffered, non-ECC stick runs at 1.20V with CL17 latency. It suits owners upgrading an existing DDR4 system or building a cost-sensitive rig that uses standard JEDEC speeds.

Single Rank 1Rx8 Organisation

The module uses a single-rank 1Rx8 layout, which determines how the memory controller addresses the chips. This rank structure is the specification that decides whether the stick works in boards limited to one rank per slot or in dual-channel pairs that expect matching ranks. Verify the motherboard manual for rank limits before purchase.

Green PCB Without Heat Spreader

The bare green circuit board has no metal heat spreader or LED lighting, keeping the profile low for tight CPU cooler clearances. This physical design changes installation only in compact cases where taller modules would interfere with the cooler. No software or firmware utilities are bundled with the memory.
