Hey evryone, new to overclocking but ive done a little research. I have a 1090t on air cooling set at 20 multiplier and fsb at 204. Vcore @ 1.42v and ram at 9-9-9-27 @ 1.59v. My computer tends to crash crysis after about 15 to 20 min of play and intel burn in test says the overclock is unstable. Temps are fine on the cpu. I really want to get the cpu to 4.1GHz but i have not touched the northbridge settings which ma be what i need to do, any tips would be appreciated.
