PCStats has posted a review on the SiS 655FX Chipset
Reference Motherboard

Today we have the opportunity to take a close and personal look at the newest member of the SIS chipset family for the Intel Pentium 4 processor; the SIS 655FX. There's more to the 655FX than just a dual channel memory controller and 800 MHz FSB compatibility though, the brand new SIS 655FX and accompanying SIS 964 Southbridge each contain some very innovative technologies developed by SIS. These technologies give the SIS655FX a performance level equal to that of Intel's very popular i865PE 'Springdale' chipset, and in some cases, to that of the high end i875P 'Canterwood' chipset. Remarkable you say? With the 655FX, SIS are introducing an interesting new technology known as 'HyperStreaming'... but more on that in a moment. By default the SIS 655FX supports Intel Pentium 4 processors running on a 400-thru-800 MHz FSB. The chipset also packs in a dual channel PC3200 memory controller, meaning it can provide the Pentium 4 with up to 6.4GB/s of bandwidth.
