Hey Patriote.

Try turning the HT link voltage to 1.6v and lower MCP/SPP links down to 4X. Also mess with unlined and linked memory speeds. Also there are FSB holes on the 680i, so upping FSB past the point you are stuck.

Also what MCP chip does the board have? It will either be the 570 or 590.

Hope this isnt another stumbling block...
