AIDA64 Extreme v8.20

The industry-leading system information and diagnostic tool. The late 2025 'v8.20' generation is now a native 64-bit application, featuring a high-speed compiler for faster startup, full Unicode localization, and native support for NVIDIA RTX 50-series (Blackwell) and AMD Zen 6 architectures. It remains the gold standard for custom SensorPanels and stress testing. While it is a premium $66 investment, its hardware database of over 250,000 entries and specialized external LCD support (Turing/Turzx) are unmatched in the diagnostic space.
