So I swapped out my 3500+ for an FX53. I've been trying to push it to 2.6 but I just can't get it there. I have a Tt Big Typhoon with AS 3 and my system is in my sig. I tried just uping the multi to 13 (gets me to 2.61) but prime 95 failed after about 15 minutes. I get the same result if I up the FSB to 2.6. At 2.55, the speed that is stable right now, the FX idles around 30-32C and at load is in the mid 40s. I also tried raising the voltage to 1.6. I was wondering if anyone had suggestions about getting it up to 2.6.
