ASUS P/I-P55T2P4 (Revision 3.1)
Socket 7 / Intel 430TX, 1997. This entry documents one exact board model/revision; its specifications are not interchangeable with similarly named variants.
REVISION WARNING: Confirm the PCB silk-screen, assembly/AA code and firmware ID on the actual board. Where documentation does not identify one PCB spin, this record states the exact documented model and explains the revision distinction below.
Specifications
| Exact model / revision | P/I-P55T2P4 PCB revision 3.1 |
|---|---|
| CPU / socket | Socket 7; Intel Pentium/Pentium MMX class and supported compatible Socket 7 CPUs per ASUS list |
| Chipset / platform | Intel 430TX northbridge and PIIX4 southbridge |
| Memory | 168-pin DIMM and 72-pin SIMM sockets; mixed population rules and supported memory types are manual-specific |
| Form factor | ATX |
| I/O and expansion | AGP 1x/2x, PCI and ISA expansion; AT keyboard, IDE, floppy, serial/parallel headers and PS/2 mouse support depend on configuration |
| Firmware compatibility | ASUS Award BIOS; BIOS revision and CPU voltage/VID support are material for later Socket 7 processors |
Compatibility and revision pitfalls
P/I-P55T2P4 and P/I-P55T2P4S are not interchangeable identities. This page is for PCB revision 3.1; check the printed revision and CPU voltage requirements. DIMM/SIMM combinations, SDRAM density and parity support are not generic.
Socket fit alone is not proof of support. Confirm the manufacturer CPU support list, the board's minimum BIOS, memory population table, and exact chassis/power requirements before operation.
Preservation notes
Photograph PCB revision, voltage jumpers, SIMM/DIMM banks and BIOS label before changes. Keep original setup documentation; old electrolytic leakage, corrosion around battery and fragile cache/VRM components deserve inspection.
Record provenance, date/serial codes, board and firmware revision, known repairs and test conditions. Photograph labels and connectors before cleaning or component removal; retain original firmware and configuration data when possible.
