The Z790 AORUS TACHYON is Gigabyte's overclocking-focused ATX board for Intel's LGA1700 processors, built around DDR4 memory rather than the newer DDR5. It carries a heavy power stage, dual BIOS with an overclocking recovery mode, and a layout aimed at extreme CPU and memory tuning. That makes it a specialist pick: most Z790 boards now favor DDR5, so the TACHYON mainly appeals to builders who already own fast DDR4 kits or chase benchmark records. Reviewers treat it as a capable but niche board, strong on power delivery and tuning tools, thinner on everyday connectivity than mainstream rivals.

Owners and reviewers describe the TACHYON as a solid overclocking platform with strong power delivery and useful dual BIOS recovery. The common complaint is the DDR4-only design, which limits its appeal next to DDR5 Z790 boards.
