⚙️ Fit Notes
- This CPU requires a Socket 940 platform (not Socket 939 / AM2 / Socket F).
- Many Socket 940 systems require ECC Registered DDR-400 memory (platform dependent).
- Before install, confirm the motherboard/system BIOS supports dual-core Opteron 285 (some platforms require a BIOS update for dual-core support).
- Always clean off old thermal compound and apply fresh thermal paste such as Shin-Etsu G751.
