It will work in the existing F1207 boards such as Asus one that is set to launch this week.
But the CPU in its dual 4x8 configuration will need the Hypertransport (HT) 3.0 to make it work in its full power and this is exactly what AMD wants to use for these CPUs.
The CPU sports 2MB of L3 cache. It also supports dual link DDR 2 up to 1066MHz memory. HT 3.0 links up to 20.8 GB/s second generation I/O with PCIe Gen 2 support, enhanced crossbar switch. The kit has a separate Northbridge power supply, and boasts more accurate measurements with multiple heat points monitored, with P-state lowered if the CPU gets too hot plus a TSI digital fan control interface.
It also supports dual 128-bit SSE date flow, dual 128 bit load per cycle, bit manipulation extensions and SSE instructions such as EXTRQ, INSERTQ, MOVNTSD and MOVNTSS.
