Frequently Asked Questions
Has this processor been tested in a working Socket 7 motherboard?
No. Evaluation is visual inspection only; function testing has not been performed.
Can the bent pins be straightened for computing use?
Several pins along the outer corner are bent. Straightening gold-plated PGA pins carries the risk of pin fatigue or breakage, which is why this piece is offered untested as scrap or repair.
What am I getting, and what condition risk am I taking on with this processor?
You receive the exact Intel Pentium MMX processor shown in the photos. Because it is untested, has visibly bent pins, and is sold as-is for gold recovery or repair, functional operation is not guaranteed.
Straight out of the multimedia computing wave of 1997, built with substantial ceramic and real gold pins. Whether it goes into a recovery batch or under a magnifying visor for pin straightening, the raw hardware is right here.
