Features of the P6DBS, P6DBE, P6DBU, P6SBU, P6SBS,
P6SBA and P6SBM Motherboards
CPU
• Celeron SEPP 266-433 MHz or dual Pentium II 233-333 MHz at 66 MHz
bus speed or dual Pentium II 350-450 MHz or dual Pentium III proces-
sors at 100 MHz bus speed (Note: The P6SBU, P6SBS, P6SBA and P6SBM support
a single processor only.) (Also see note on processors - page 2-3.) (*Note: Currently, the
P6DBE/P6DBU/P6SBU/P6SBA motherboard supports CPU speeds up to 1GHz with 100 MHz
FSB speed.)
Memory
• Maximum of 1 GB EDO at 66 MHz or 512 MB unbuffered 3.3V SDRAM,
or 1 GB registered SDRAM (P6DBS/P6DBE/P6DBU/P6SBU/P6SBS only)
• 768 MB EDO, 768 MB registered DIMM or 384 MB SDRAM (P6SBA and
P6SBM only)
(Note: When the CPU bus is running at 100 MHz, the SDRAM must be PC-100 compliant
DIMMs.)
(Note: The maximum cacheable memory size depends on the processor capabilities.)
• ECC and non-ECC memory supported
Chipset
• Intel 440BX
