Intel Pentium Pro Renewed Memory Module SL22V 256KB

The Intel Pentium Pro KB80521EX200 SL22V 256K is a processor from the Pentium Pro family, designed for use in desktop computers during the mid-1990s. It was one of the first x86 processors to introduce a fully 32-bit architecture, which allowed for more efficient memory management and better performance in multitasking environments. This particular model is a renewed version, meaning it has been refurbished and tested to ensure it meets original specifications. The processor is known for its reliability and performance in its era, making it a valuable component for vintage computing or retro system builds.

The Pentium Pro was a significant step forward in Intel's processor lineup, offering improved performance over its predecessors and setting the stage for future Intel processors. It was primarily used in business and professional environments due to its advanced features and performance capabilities. The 256KB L2 cache included in this model helps reduce latency when accessing frequently used data, improving overall system responsiveness.

The processor operates at a clock speed of 200 MHz with a bus speed of 66 MHz, and it uses a clock multiplier of 3. It has a core voltage of 3.3 volts with a tolerance of ±5%, ensuring stable operation under various conditions. The maximum case temperature is 85°C, which indicates the thermal limits for safe operation. The L2 cache stepping is denoted as "b," which refers to a specific revision of the cache design.
