Applications
The Cognac 20000731 is an OEM motherboard produced by HP for the Pavilion 7638 desktop, which was part of HP's late-1990s/early-2000s consumer desktop lineup. Socket 370 was Intel's mainstream CPU socket for Celeron and Pentium III processors during roughly 1998–2002, bridging the transition from the earlier Slot 1 packaging to the later Socket 478 Pentium 4 platform. Boards like this are used today primarily as direct replacements for existing HP Pavilion 7638 systems that need a working motherboard to return to service. The integrated graphics, audio, and USB make it a straightforward drop-in replacement without the need for additional expansion cards in a standard configuration.
This HP Compaq Cognac 20000731 PGA370 Socket 370 Motherboard has been tested at our facility and is in good working order. The board shows normal cosmetic wear consistent with prior use, including light surface marks on the PCB. All visible connectors, expansion slots, and rear I/O ports appear intact and undamaged.
