How much volt on vcore you think is safe? I would say 1.475 also is supersafe.. even 1.5 - on high end air cooling. I just ordered a zalman 9700LED from komplett to test out that one, the bigtyp 120 VX is good, but the mounting bracket don't push the copper base tight enough onto the cpu, so i actually believe I could've gotten atleast 5 celcius less if it was tight enough... the zalman is supposed to be better. Try another cooler and PUSH THOSE VOLTS :cool: I don't believe 2550 mhz is the top... I resist to believe it :D
