⚙️ Fit Notes

• Socket must be LGA1156 (not compatible with LGA1155 / LGA1150 / LGA1366).
• This CPU does not have integrated graphics — a compatible discrete GPU may be required depending on your motherboard/platform.
• Ensure your motherboard BIOS is updated to a revision that supports Intel Core i5-750 (Lynnfield) before installation.
• When reinstalling a CPU, clean and reapply thermal compound (recommended: Shin-Etsu G751).
