Description

90 day warranty working pull includes 64mb ram and Celeron 466 CPU

The COGNAC Micro ATX motherboard offers a time to market consumer and corporate desktop solution featuring the Intel Celeron PPGA processor with 66/100MHz front side bus and the Whitney chipsets in a Micro ATX low profile motherboards. In addition, the integrated onchip graphics controller supports 4MB of SDRAM purpose of Display cache memory. The Cognac motherboard was designed to be highly minimized system cost. In this effort a smaller form factor, Micro-ATX, gives the greater space economy and more affordable systems. Integrating onchip graphics controller and SDRAM, as well as onchip AC’97 audio solution with AC97 Codec onto the motherboard eliminates the need for more expensive graphic and audio add-in cards. The end result is a system platform with a primary component level of integration with translates into affordable solution for entry level users.

COGNAC motherboard provides the 370pin PGA370 socket that is not backward compatible with ZIF socket-7 processors The Processor’s VID pins automatically program the voltage regulator on the motherboard to the required processor voltage. The motherboard supports processors that run internally at 300/333/366/400 /433/466/500MHz.

The motherboard has two, dual inline memory module (DIMM), minimum 16MB to maximum 256MB memory size. The BIOS can automatically detect the memory type, size, and speed through SMBUS interface between the core chipset and DIMM module.
