Applications

The Pentium 4 640 was used in desktop systems from the mid-2000s, compatible with Intel 945, 955, and 965 chipset boards. Suitable for legacy system rebuilds, retro computing projects, or replacement in existing Socket 775 platforms. Not suitable for modern workloads.

Condition: Used
This Intel Pentium 4 640 SL7Z8 3.20GHz Socket 775 processor has been tested and confirmed to be in working order. The integrated heat spreader shows dried thermal paste residue from prior installation, which is normal for a pulled CPU — the thermal paste can be cleaned off before installation. The LGA775 contact lands on the underside are present and in good condition with no visible bent or missing contacts. This is the CPU only; no heatsink, fan, or cooler bracket is included. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
