8 GB DDR4 DIMM for desktop upgrades

This SK hynix module delivers 8 GB of DDR4 memory at 3200 MHz with CL22 latency. It is built for desktop systems that accept 288-pin unbuffered non-ECC DIMMs and runs at the standard 1.2 V. The 1Rx8 organisation suits mainstream boards that support PC4-25600 speeds.

288-pin gold-edge connector fits standard slots

The DIMM uses the industry-standard 288-pin edge connector, so it seats directly into any desktop DDR4 slot without adapters. Gold-plated contacts resist oxidation and maintain reliable electrical connection over repeated insertions. No extra cables, brackets or drivers are required for installation.

Verify DDR4 288-pin support

Check that your motherboard lists DDR4 3200 MHz (PC4-25600) and 1.2 V operation in its memory QVL. Confirm the board accepts unbuffered non-ECC 1Rx8 modules and has a free 288-pin slot. Systems limited to lower speeds will down-clock the module automatically.
