ATX Power Installation
The system power is provided to the motherboard with the ATX1 and
ATX_12V1power connectors. ATX1 is a 24-pin power connectorand
ATX_12V1is a 4-pin 12V power connector.
The 24-pin power connector can to be connected toa standard 20-pin
ATX power connector in a standard ATX power supply (Min. 400watt).
Note: The power supply 5VSB voltage must be at least 2A.
Installing the Memory
The MB877 motherboard supports two DDR2 memory sockets for a
maximum total memory of 2GB in DDR2 memory type. It supports DDR2
400/533/667wheninstalled with CPUs that have clock speeds of 533MHz.
The board provides dual channel functionality for its DIMM slots.
DIMM1is for one channel and DIMM2is for another channel.
Basically, the system memoryinterface has the following features:
Supports two 64-bit wide DDR2 data channels
Available bandwidth up to 3.2GB/s (DDR2 400) for single-channel
mode and 6.4GB/s (DDR2 400) in dual-channel mode.
Supports 128Mb, 256Mb, 512Mb, 1Gb DDR2 technologies.
Supports only x8, x16, DDR2 devices with four banks
Registered DIMMs not supported
Supports opportunistic refresh
Up to 16 simultaneously open pages (four per row, four rows
maximum)
