The long-floundering SiS R659
chipset with quad-channel PC1200 RDRAM support appears to be a dead duck
Rambus Inc.'s last-ditch effort to maintain a presence in the high-performance computing arena seems to have fizzled now that Taiwan's largest motherboard maker, Asustek Computer Inc., has quietly withdrawn support for Rambus technology.
A project manager who asked not to be identified says that the Asus R659 product was pulled because its performance was not as "exciting as we expected." Despite reports that SiS may have a follow up to its R659 chipset, Rambus has said that they have not recently provided any direct design support, suggesting that this is the end of the line for desktop RDRAM.
