Product Overview
Operating at 200 MHz on Intel's P6 microarchitecture, the KB80521EX200 SL22Z multi-chip module integrates a 512 KB dedicated Level 2 cache running at full core speed alongside the CPU core under an oversized gold-plated lid. Built for high-end workstations and enterprise servers of the late 1990s, this processor is housed in a 387-pin ceramic staggered pin grid array (CPGA-387) for Socket 8 motherboards. Extensive gold plating covers both the package lid and pin matrix, making it sought after by scrap refiners, vintage hardware collectors, and electronics restoration technicians.

Frequently Asked Questions
Are the bent pins repairable?
Some technicians straighten pins using a mechanical pencil tip or needle, but pin realignment carries the risk of pin fatigue or breakage. This unit is offered as-is with bent pins as documented.
What cache size does this specific SL22Z processor have?
This unit is marked 512K, indicating a 512 KB Level 2 cache integrated directly on the substrate at full 200 MHz core speed.
What is the condition risk on this unit?
This processor has multiple bent pins along outer rows and has not undergone function testing. It is sold for scrap precious metal recovery, pin restoration, or display, with the photos serving as the specification of physical condition.
Gold-topped ceramic from the dawn of out-of-order execution, whether it meets the torch for its metals or the tweezers for a bench resurrection.
