The system power is provided to the CPU card with the CN1 and J7 ATX 
power connectors. Please note that the J7 external ATX power connector 
should be connected to the backplane for IB865 to function. J7 is a 3-pin 
power connector. CN1 is a 4-pin 12V power connector. CN1 is to be 
connected to the ATX power supply.  

 

 
The IB865 CPU card supports two DDR memory sockets for a maximum 
total memory of 2GB in DDR memory type. You can install unbuffered 
& non-ECC DDR DIMMs. It supports DDR266/333 when installed with 
CPUs that have clock speeds of 533MHz. It supports DDR266/320/400 
when installed with CPUs that have clock speeds of 800MHz. The board 
provides dual channel functionality for its DIMM slots. DIMM1 is for 
one channel and DIMM2 is for the other channel.  Enabling dual 
channels can increase data access rates.  
 
Basically, the system memory interface has the following features: 

Supports two 64-bit wide DDR data channels 
Available bandwidth up to 3.2GB/s (DDR400) for single-channel 
mode and 6.4GB/s (DDR400) in dual-channel mode. 
Supports non ECC DIMMs. 
Supports 128Mb, 256Mb, 512Mb DDR technologies. 
Supports only x8, x16, DDR devices with four banks 
Registered DIMMs not supported 
Supports opportunistic refresh
