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, which are 70 new
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 supports 133-MHz GTL+ host bus frequencies for Pentium III
processors running at 800 MHz and above.
The four DIMM sockets on board allow memory upgrade to a maximum of 2 GB using
four 512-MB SDRAM (Synchronous DRAM) DIMMs. (The DIMM sockets also allow
1024 MB for a maximum upgrade of 4 GB in future models.) For data integrity, the
default setting of the ECC (error-correcting code) function of the memory system in BIOS
is enabled.
Note: Only 3.3-volt SDRAM DIMMs should be used. 5-volt memory devices are not
supported.
The system board supports 133-MHz registered SDRAM; 66-MHz SDRAM is not
supported.
