I just over @ Hardwarezone.com and I noticed that they have posted a 4 page preview of SiS upcoming 655 chipset featured on Asus P4SDX. Here's a snip: What looked like a normal product release turned out to be a shocker when we unzipped the attachment. Inside, ASUS revealed to us for the first time, pictures and specifications of their newest SiS-based motherboard for the Intel Pentium 4. The new SiS655 chipset is not even revealed at the SiS website and here, ASUS already had a sample. Although information was scarce, we later realized that the SiS655 is the next generation of P4 chipset that will support dual-channel DDR333 memory. This would immediately bring obsolescence to Intel's much anticipated Granite Bay as its theoretical memory bandwidth is much larger - up to 5.4GB/s while dual-channel DDR266 chipsets would only deliver 4.2GB/s.
