Support

The P4SCT/P4SCT+/P4SCT+II supports Dual channel, ECC/non-ECC,

unbuffered DDR-400/333/266 SDRAM. (Populate DIMM0A,DIMM1A and/

or DIMM0B, DIMM1B with memory modules of the same size/same type

will result in the dual channel, two-way interleaved memory which is

faster than the single channel memory.

(*Note: The BIOS will display 320 due to the limitation of Intel’s chipset).

(*Note: The Canterwood chip supports non-ECC or ECC memory. If ECC
memory is installed, the ECC bits need to be initialized via BIOS before normal
operation. For a 4 GB-Memory and 2.4-GHz P4 system, it will take about 65
seconds for all the ECC bits to be initialized before any video displays. Since
ECC initialization takes time, the Watch Dog Timer Select needs to be set to a
time longer than what the ECC initialization will take.)
