Editing Silicon Integrated Systems (section)

===Socket 478, Socket 775===
SiS and [[Acer Laboratories Incorporated|ALi]] were the only two companies initially awarded licenses to produce third party chipsets for the [[Pentium 4]]. SiS developed the 648 chipset with this license (SiS 648 B Stepping supports Intel Hyper-Threading CPU on some motherboards like MSI 648 Max).<ref>Lal Shimpi, Anand.
