two things:
first.
what. ever. lol that 3600 will likely hit at least 2.8 with no voltage increase...let alone liquid cooling.
second.
your temp problem is likely the mobo. the mobos are made for 90nm chips and so the 65nm cpus freak them out, so to say.
MAKE SURE your hsf is seated properly and your as5 is applied correctly.
now, what i have found is that coretemp is usually about half-right lol. so, if it says 13*, you're at about 26.
another thing...if your cpu is 60*c idle, touch the hsf heatpipes. did they burn you? then they are probably not anywhere near that temp.
b1gapl he means by the raising ram thing that in his bios it says "ram limit", where you set it to ddr2-400, 533, 667, or 800 aka those screwy dividers i was tellin ya about.
another thing andrew...lower that setting to AT LEAST 667. it will help you keep your ram stable until you know a little more about oc'ing.
ask away i am glad to help.
