well my 2400+ o/c to 2.3 with only 1.725 core... STABLE.... and im on crap heatsink (volcano 9).... when i get my slk-800 and dont have to worry about going over 55c load... ill try for 2.4-2.6 with 1.85 or more vcore so NO complaints here with the 2400+, as for the nforce 2, ill only get it if u can lock your pci clocks when you change your fsb (like intel has)......
