Processors
The Pentium III processor implements Dynamic Execution performance, a multi-
transaction system bus, and Intel MMX media enhancement technology. Also, it
offers Streaming SIMD (Single Instruction Multiple Data) Extensions - 70 ne
instructions enabling advanced imaging, 3D, streaming audio and video, and
speech recognition applications. The Pentium III processor delivers higher
performance than the previous Pentium processor while maintaining binary
compatibility with all previous Intel Architecture processors.
This system board currently supports 100 or 133 MHz GTL+ host bus frequencies
for one Pentium III processor running at 667 MHz, 733 MHz, 800 MHz, or 866
MHz.
Memory
The three DIMM sockets on board allow memory upgrade to a maximum of 1.5
GB using three 512-MB SDRAM (synchronous DRAM) DIMMs. For data
integrity, the default setting of the ECC (error-correcting code) function of the
memory system in BIOS is enabled. See “Memory/Cache options” on page 83 for
more on this BIOS setting.
Note:
The SDRAM should work under 3.3 volts only; 5-volt memory devices
are not supported.
The system board supports both 100 and 133 MHz SDRAMs; 66 MHz SDRAMs
are not supported.
