i got mine to boot with 3,959 mhz on air with 1,7 Vcore set in bios( scary lol). the computer worked fine but it lasted about 2 sek in prime. my best stable clock is 3,6ghz and 1,6Vcore. ran prime for 8 hours (small fft witch produces most heat btw) and the temp was about 60C all the way on air...lots of it

my 24/7 is 3,4 ghz and Vcore 1,45
