Processor The SF2 motherboard uses a micro PGA 478-pin socket that
has the following features:
•
Supports 800/533/400 MHz system bus
• Supports “Hyper-Threading” technology CPU
“Hyper-Threading” technology enables the operating system
into thinking it’s hooked up to two processors, allowing two
threads to be run in parallel, both on separate ‘logical’ proces-
sors within the same physical processor.
Chipset The SiS648/SiS648FX/SiS661FX Northbridge and
SiS964/SiS964L Southbridge chipsets are based on an inno-
vative and scalable architecture with proven reliability and
performance.
The motherboard may support either of the Northbridge and
Southbridge chipset mentioned above. Refer below for the
combination and respective details:

AGP
The motherboard includes an AGP slot that provides eight
times the bandwidth of the original AGP specification. The
AGP 3.0 (8XAGP) offers a significant increase in performance
along with feature enhancements to AGP2.0. This interface
represents the natural evolution from the existing AGP to meet
the ever-increasing demands placed on the graphic interfaces
within the workstation and desktop environments.
Audio
The motherboard supports 16-bit stereo full-duplex CODEC
with independent and variable sampling rate and advanced
power management. Incorporated with proprietary converter
technology. The digital interface circuitry operates from a 3.3V
power supply and supports an AC'97 2.3 compliant SPDIF out
function that allows easy connection from the PC to other elec-
tronic products. Further features include support for four
analog line-level stereo inputs.
