| Catalog path | Intel → Pentium generations |
|---|---|
| Model / launch era | Intel Pentium III 800EB (Coppermine); Coppermine Pentium III, Q3 2000 |
| Cores / threads / frequency | 1 core / 1 thread; 800 MHz; 133 MHz system bus |
| Package / socket | Socket 370 FC-PGA (Coppermine 800EB) |
| Cache | 32 KB L1; 256 KB on-die L2 running at full core speed |
| TDP | 20.8 W thermal design power |
| Memory / bus | PC133 SDRAM on a 133 MHz system bus via the motherboard chipset; chipset/board controls capacity and supported DIMM types. |
| Platform compatibility | Requires a Socket 370 board and BIOS supporting the 133 MHz FSB Coppermine Pentium III at the processor voltage. The “B” denotes the 133 MHz bus and “E” the Coppermine generation; verify FC-PGA support and cooling, as socket fit does not imply electrical compatibility. |
Compatibility and service notes
- Requires a Socket 370 board and BIOS supporting the 133 MHz FSB Coppermine Pentium III at the processor voltage. The “B” denotes the 133 MHz bus and “E” the Coppermine generation; verify FC-PGA support and cooling, as socket fit does not imply electrical compatibility.
- PC133 SDRAM on a 133 MHz system bus via the motherboard chipset; chipset/board controls capacity and supported DIMM types.
- 800EB (133 MHz bus) is distinct from Pentium III 800E (100 MHz bus) and Slot 1 cartridge models.
- 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.
