Core 2 and Quad support and DDR 2 or 3
The boards based on Intel's P35 are getting ready and we saw the specification of some of them. The one we had a chance to see is based on Intel's P35 Northbridge and ICH9R Southbridge. The chipset is also well known as a Bearlake P.
The board supports four memory slots and there will be DDR2 and DDR3 versions of it. It comes with a single PCIe 16X slots and two to three PCIe ports.
As this chipset does have an IDE part you need to use J-Micron or similar chip to this, but the chipset supports 12 USB connectors, six SATA 2 ports via ICH9R with Raid 0,1,5 and 10 support.
The good news is that the P35 boards will ship with both Vista and XP drivers. You should be able to see some announcements by the end of the May but the 4th of June, or the first day of Computex, is the real launch with massive availability just after.
