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.

Questions about this item
What does the 2400 MHz rating mean for actual system performance?
The module runs at 2400 MT/s with CL17 latency, giving a PC4-19200 bandwidth rating that the memory controller can sustain in typical desktop workloads.
What does the PC4-19200 designation limit in practice?
PC4-19200 is the JEDEC standard name for DDR4-2400; it caps the official data rate at 2400 MT/s and 1.20 V unless the BIOS applies an XMP or manual overclock.
Will this 288-pin DIMM fit my motherboard slot?
Yes — it is a standard 288-pin unbuffered non-ECC DDR4 DIMM, the form factor used by virtually all current desktop boards.
