hay peeps iv been tyring to reach 4.2 ghz on my 1090t with all 6 cores. I managed to run prime blend test for just over 30 mins.with ok temps.but then my system crashed.. iv been using the multiplyer methond and leaving everything els on auto apart from my dram(1.55) and my offset cpu (1.488) i notice in cpu-z for my nb and ht there both at 2000mhz i was wondering if anyone can tell me if i just have to keep bumbing up my cpu volltege to get 4.2ghz stable or if ajusting the nb and ht link speed along with maybe other voltages is an alt insted of incressing the cpu voltage. thanks
