The Phoenix ATX Express supports two types of memory organization: Dual
channel (Interleaved) mode - this mode offers the highest throughput for real world
applications and Single channel (Asymmetric) mode - this mode is equivalent to
single channel bandwidth operation for real world applications.
PROCESSOR
The latest revision of the Phoenix ATX Express currently supports Intel Pentium 4
processors in an LGA775 processor socket with a 1066, 800, or 533 MHz system
bus.
Use Only ATX12V compliant power supplies.
A well-dimensioned cooling FAN must be used and use a plastic cooler back plate
when installing the fan cooler assembly on to the CPU.
