viasli s SLI Capable chipsets By VIA For Both AMD & Intel

VIA has unveiled it’s upcoming PCI-Express chipsets to HKEPC. VIA has introduced a series of Dual Graphic Capable chipset. Although Nvidia has only officially reworked it’s forceware drivers for official SLI support on the Nvidia Nforce 4 range of motherboard chipsets and the Intel Serverworks Tumwater chipset, Many manufacturers has successfully engineered their mainboards to accept two PCI-Express graphics card, either in a 8x + 8x configuration of 16x + 4x configuration. VIA’s latest chipsets, the PT880Pro, PT894Pro and K8T890Pro will demonstrate all these.

VIA has unveiled it’s upcoming PCI-Express chipsets to HKEPC. VIA has introduced a series of Dual Graphic Capable chipset. Although Nvidia has only officially reworked it’s forceware drivers for official SLI support on the Nvidia Nforce 4 range of motherboard chipsets and the Intel Serverworks Tumwater chipset, Many manufacturers has successfully engineered their mainboards to accept two PCI-Express graphics card, either in a 8x + 8x configuration of 16x + 4x configuration. VIA’s latest chipsets, the PT880Pro, PT894Pro and K8T890Pro will demonstrate all these.

the VIA K8T890Pro supports 20 PCI-Express lanes and there will be one PCI-E X16 slot and another PCI-E x4 slot on board for dual graphic cards support. why it isn’t possible to split the PCI-Express lanes evenly between the two slots? The reason lies within the chipset, VIA has locked the first PCI-E graphic card slot to 16 lanes, thus it is not possible for a x8 + x8 configuration to exist.

The current VIA VT8237R southbridge does not have PCI-E lanes built in, thus it is not capable of offering PCI-E x1 slots for extra devices, VIA’s latest southbridge, the VIA VT8251 will rectify this by having 2 PCI-E lanes built within.

The VIA PT894Pro is built specifically for Intel LGA + PCI-E support, unlike previous chipsets from VIA which si built using the FC-BGA package, the VIA PT894Pro is built using the TSMC package on a .13 micron process. Although the reference board shipped to HKEPC only came with DDR-II memory support, the chipset will support 4Gb of memory and both DDR and DDR2 formats up to DDR400 and DDR-II 667 respectively, giving mainboard manufacturers the flexibility to integrate either or both of the memory formats on their mainboard.

As for new southbridge chipsets, VIA will be introducing the enhanced version of the VT8237, the VIA VT8237A and a totally new chipset, the VIA VT8251. The main difference between the 8237A adn the 8237 is the introduction of HD audio capabilities, like Intel’s ICH7, the chipset will support output of up to 8 channels and 192k/32bit. Otherwise, VIA VT8237 and 8237A is exactly the same, pin for pin. To utilise the HD Audio capabilities of the chipset, all mainboard manufacturers have to do is to place a HD capable audio codec onboard, like the Realtek 880/890.

unlike the VIA VT8237, the VIA VT8251 is a completely new product. It has 2 PCI-Express lanes built in, comes with SATA-II support and the the SATA ports built in chip is pumped up to 4 from the 2 found on the VT8237. VIA has also decided to implement RAID5 support on the VT8251, with support for AHCI, NCQ and Port Multipler etc. One of the things that VIA left out on the VT8251 is sadly, the support for Chipset Gigabit Lan, as it only comes with 10/100 Ethernet built-in.
