Intel Motherboard E139761 Specifications

The Intel motherboard E139761 is an Intel technology-based motherboard that computer technology company Dell and Acer Inc. subsidiary Gateway used for some of their desktop PCs. Each component supports a processor (or computer processing unit) and chipset from semiconductor company Intel Corp. Although the Intel E139761 is no longer manufactured, customers can still purchase it at a variety of online retailers.

Size and Processor

The Intel motherboard E139761 uses the Advanced Technology Extended (ATX) form factor standard, with a physical measurement of 12 by 8 inches (30.5 by 20.3 centimeters). Each E139761 supports an Intel Pentium II or III processor. The front-side bus speed, which is the rate at which the chip connects with the motherboard for data transmission via the front-side bus interface, should be 66 or 100MHz. Also, the motherboard supports processors with an instruction set architecture (ISA) speed of 8.33MHz.

Chipset and Memory

The Intel chipset on the E139761 is the 440BX, which contains the 82443BX host bridge/controller. Also included are three 168-pin Dual Inline Memory Module slots, which are based on first-generational Synchronous Dynamic Random Access Memory architecture. The DIMM RAM slots combine for a maximum capacity of 384MB. The memory access speed options are 66MHz and 100MHz.

Audio, Expansion and Connectivity

Integrated onto the Intel motherboard E139761 is the Ensoniq ES1371, a 16-bit sound card from now-defunct American musical instruments and sound technology manufacturer Ensoniq Corp. The expansion slots consist of one Accelerated Graphics Port, two ISA slots and four Peripheral Component Interconnect slots for attaching components such as a graphics processing unit or sound card.
