>Silicon Integrated Systems this week announced the release of its newest Northbridge for the Intel P4 CPU.
The SiS649 is the company’s newest chipset designed for the latest DDR and DDR2 memory standards and PCI-Express 16x.
The SiS649 supports 2 DIMMs, with 1GB per DIMM of RAM. As a chipset that vendors will be incorporating into products, the Sis649 gives vendors the option of using DDR or DDR2 in the design of motherboards.
With an 800MHz FSB and PCI-Express support, compared to the earlier SiS656 Northbridge chipset that features Dual Channel DDR-400/DDR2-667, the 649 features Single Channel DDR-400/DDR2-533.
At DDR-400/333/266, the chipset can handle up to 3.2GB/s in bandwidth. At DDR2-533/400, the chipset can handle up to 4.2GB/s in bandwidth.
According to SiS, the chipset is ideally meant to be combines with the SiS965 Southbridge chipset, which supports PCI-E x1, gigabit LAN, eight USB 2.0 ports, AC 97 7.1 channel sound, four4 SATA (supporting hot plug functionality), four ATA and multiple RAID disk array modes in RAID 0/1.
Motherboards with the SiS649 are due in September
