As we know, AMD’s SB750 SouthBridge comes with the ‘ACC’ which boosts overclocking capacity. 790GX and some 790FX already hit market with this feature. But it seems ACC is not AMD’s exclusive technology now.
This roadmap from NVIDIA unveils that the MCP72/78 can fully support AMD’s new ACC technology only with some board modifications: Utilizing JTAG interface, and making some connection between CPU and MCP72/78. As NVIDIA’s calender shows, we will see MCP72/78 motherboards supporting ‘ACC’ on 1st Sep. That may be good new for some NVIDIA fans.
BTW, It doesn’t means MCP72/78 motherboards which is already on sale can support this techlonogy, since it need some modification on hardware level.
