INSTALLATIONS
Installing the CPU
The MB900-R motherboard supports a n LGA 775 processor socket for
Intel® Pentium® 4 processors.
The LGA 775 processor socket comes with a lever to secure the
processor. Refer to the pictures below, from left to right, on how to place
the processor into the CPU socket.
LGA775 socket must always be installed during transport to avoid
damage to the socket.
Please note that the cover o f the

INSTALLATIONS
ATX Power Installation
The system power is provided to the motherboard with the ATX1 and
ATX_12V power connectors. ATX1 is a 24-pin power connector and
ATX_12V is a 8-pin 12V power connector.
The 24-pin power connector can to be connected to a 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 MB900-R motherboard supports two DDR2 memory sockets for a
maximum total memory of 2GB in DDR memory type. It supports DDR2
533/667.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 5.3GB/s (DDR2 667) for single -channel
mode and 10.7GB/s (DDR2 667) in dual -channel mode.
Supports 256Mb, 512Mb, 1Gb DDR2 technologies.
Supports only x8, x16, DDR2 devices with four banks
Supports only unbuffered DIMMs
Supports opportunistic refresh
Up to 32 simultaneously open pages (four per row, four rows
maximum)
