| TDP | 8 W typical thermal design power |
| Memory / bus | Platform/chipset-controlled FPM or EDO DRAM; 50 MHz host bus; memory population and timing depend on the board chipset. |
| Platform compatibility | Requires a Socket 5 board supporting the 3.3 V P5 Pentium and 50 MHz bus. Some later Socket 7 boards support this CPU only when the board provides the correct voltage and jumper/BIOS configuration; confirm the exact board revision and regulator before fitting. |
Compatibility and service notes
- Requires a Socket 5 board supporting the 3.3 V P5 Pentium and 50 MHz bus. Some later Socket 7 boards support this CPU only when the board provides the correct voltage and jumper/BIOS configuration; confirm the exact board revision and regulator before fitting.
- Platform/chipset-controlled FPM or EDO DRAM; 50 MHz host bus; memory population and timing depend on the board chipset.
- This 75 MHz part is distinct from the 60/66/90/100 MHz P5 Pentiums; check the CPU marking and bus multiplier/jumper settings.
- Before fitting, confirm the exact motherboard manufacturer CPU list, revision, minimum BIOS, power delivery, cooling, package and memory type. Socket fit alone does not establish electrical or firmware compatibility; never force a processor.
Service & archival record
Record the complete processor marking and S-spec/ordering code, stepping, board model/revision, chipset, BIOS/microcode, memory configuration, cooler, power profile, physical condition and provenance. Separate measured behavior from published specifications.
Handle the package by its edges and protect contacts. Inspect for contamination, damaged pins/pads, socket damage and uneven cooler pressure before use.
