Processor
•
The mPGA Socket 478
•
Supports
Intel Pentium 4 series
CPUs
•
Supports up to 400/
533
MHz system bus
Note:
Only when the mainboard incorporates the
SiS651 Northbridge chipset can the system bus
s u pport up to 533 MHz.
Chipset
The
SiS650/SiS650GL/SiS651
Northbridge and
SiS961/SiS962
Southbridge chipsets are based on an innova-
tive and scalable architecture with proven reliability and
performance.
The mainboard may support either of the Northbridge and
Southbridge chipset mentioned above. Refer below for the
combination and respective details:
•
SiS650
Northbridge and
SiS961
Southbridge – Support
up to 400 MHz system bus, ATA 100 interface and DDR
266.
•
SiS650GL
Northbridge and
SiS961
Southbridge - Sup-
port up to 400 MHz system bus, ATA 100 interface and
DDR 266. (
Note:
Without 4xAGP slot)
•
SiS651
Northbridge and
SiS962
Southbridge – Support
up to 533 MHz system bus, ATA 133 interface, DDR 333
and USB 2.0 controller.
Memory
•
Two 168-pin DIMM slots for SDRAM memory modules
•
Two 184-pin DIMM slots for DDR memory modules
•
Support SDRAM up to 133 MHz /DDR up to 266 MHz
memory bus
•
Maximum installed memory is 2GB
Notes:
1.
For
SiS962
Southbridge chipset, DDR can sup-
port up to 333 MHz memory bus.
2. Do not use SDRAM and DDR concurrently.
Expansion Slots
•
One AMR slot for a special audio/modem riser card
•
One 2x/4xAGP slot
*
for AGP 2.0-compliant interface
•
Two 32-bit PCI slots for PCI 2.2-compliant bus interface
Onboard IDE
channels

/133
modes
*
When the mainboard incorporates the
SiS650GL
Northbridge chipset, the mainboard will not sup-
port the 4xAGP slot.
