⚙️ Fit Notes

• Match your original CPU part number whenever possible
• Confirm your laptop uses Socket S1G4 / S1g4, not S1G1, S1G2, S1G3, AM2, AM3, FS1, or other socket types
• Confirm your system BIOS supports the Phenom II N660 / HMN660DCR23GM
• Confirm your cooling assembly supports a 35W mobile processor
• Socket S1 revisions are not all electrically compatible even when the package looks similar
• This is a mobile laptop CPU and is not compatible with desktop AM2 / AM3 motherboards
• Some laptops require a BIOS update before installing a different CPU
• CPU support can vary by motherboard revision, graphics configuration, chipset, and thermal design
• Apply fresh thermal compound during installation: Shin-Etsu G751 Thermal Grease
• Reuse the original heatsink, fan, screws, and mounting hardware unless replacements are included
• Always disconnect AC power, remove the battery when applicable, and follow proper ESD procedures before replacing a laptop CPU
• Do not install if your system requires a different socket, different TDP class, soldered CPU, or unsupported BIOS microcode
