I just purchased a new CPU to replace my AMD Phenom II X6 1090T. I picked up a AMD FX 8320 CPU which was going pretty cheap so thought why not. I am able to hit 5GHz with it but becomes unstable when it hits 70C which i believe is the max rated temp from AMD, or at least according to AMD overdrive. Now i may still have some tweaking as i am using 1.43v and using a Gigabyte 990FXA Rev1.0 motherboard so has no load line calibration i am also thinking of buying a new motherboard too then sell my processor and motherboard on. So thoughts on a good motherboard is also welcomed. So looks like i am in a market for a new cooler, it may also be the thermal compound i have got is crap too since it is the generic Arctic cooling, i do have some IC Diamond 7-Carat Thermal Compound in the post so hopefully that should make a difference. The CPU cooler i am currently using is the pretty old now Thermalright Silver Arrow with the two stock 140mm fans. AT present i am running along at 4.5GHz witch stock voltage and max's out at 40C Any ideas?
