if youre gonna oc it that much you might not be able to run it on air cooling, probably will only be stable under water cooling, but dont qoute me on that.
People are running there Opteron's at 3ghz on air... Just because I want to hit 3ghz on air, doesn't mean I will be able to. It just means that is my goal. I can't force the cpu to do 3ghz stable if it only wants to do 2.8.
1.7vcore should be max on AMD64s especially on air...anything over that has been known to fry the memory controller...generally speaking for air on a 90nm core we're talking +0.25 stock vcore
170 has a 10x multiplier and 300HTT is nothing so long as you lower LDT ratio and increase LDT and chipset voltage to recommended values...easiest way of testing max HTT is to lower CPU multiplier and increase HTT with memory divider
