The chipset used for the Vishera is the same 990/970 used with the last generation. Good news for AMD fans in that your AM3+ 990FX motherboards will still provide a home for your new FX Vishera chip with only a BIOS update. The block diagram shows PCIE 2.0 lanes broken down as 2x16 or 4x8 +8x1+4x1 (2x1 on SB). Up to 14 USB ports are supported (up to four being USB 3.0) and six 6Gbps SATA ports and support for RAID configurations of 0, 1, 5, and 10. DDR3 officially supports up to 1866MHz of 1.5v, but supports up to 2400MHz (OC). I won't dwell on this too much as it's largely the same as the last release. So as a refresher course, here is a block diagram for your perusal.
