With both the Gigabyte 8S655TX Ultra and Asus P4S800D-E based on the same North Bridge/South Bridge combination, there are many common features provided by the chipset.



The 655TX North Bridge provides the Dual-Channel memory controller with support for up to 4GB of DDR400 memory. Support for 8X/4X AGP is also provided by the 655TX.



The Introduction of the 964 South Bridge with the most recent SiS chipsets has allowed motherboards based on the SiS chipset finally to compete on features with the best from Intel. The 964 allows both the Asus and Gigabyte to offer 8 USB 2.0 ports, dual ATA133 IDE, Serial ATA with the option for RAID 0 and 1, and 6-channel audio.

    The board actually supports 128bit or dual 64bit mode from what i remember looking at the bios.

    errrr, #2, lay off the weed.

    Everybody has to remember that SiS is only marginally better than VIA in compatibility, and several degrees less than any Intel modern chipset.
    .
    This makes SiS an excellent option for AMD based motherboards, but why on Earth would you pair an Intel processor with anything other than an Intel chipset? The whole point of paying the $$ for an Intel CPU is the benefit of getting to use their chipset. Works with everything, always.
    .
    That's worth the extra $20.

    Did I miss something? IN the conclusion it said it packs dual channel 128 bit DDR?
