FX 8320 not going past 3.7ghz
FX 8320 not going past 3.7ghz
i own a gigabyte ga-78lmt-s2p and recently added an fx 8320. i noticed the only reliable multipliers are the stock (17.5x) and 18.5x. i haven’t attempted fsb overclocking because i think it would also affect my ram, which is 2x kingston 4gb at 1600mhz—something i prefer to avoid. my nb and ht are set to 2600mhz, and the cpu voltage is at 1.375v (the stock setting). with a sella 92mm cooler keeping everything under 52°C, should i increase the fsb (it was running at 208 with my old fx-4130)? or should i focus on finding a stable multiplier? would switching my psu help, since i’m about to install a 600w njoy agon psu and it might not be able to maintain my r9 290?
After some adjustments I discovered a stable clock at 208FSB*20.5= 4.264GHz. my NB and HT links are configured at 2496mhz and 2288mhz. increasing the multiplier causes instability. i require just a slight boost in single-core performance so I can stop working. everything runs fine at standard voltages, but higher voltages lead to excessive heat in the surrounding components. even minor changes to the FSB keep RAM stable at around 1664mhz.
Verify your board. That one is clearly entry-level. A decent board for its price, don't misunderstand. However, that could be part of the issue. Also, I'm unfamiliar with that brand of power supply, so I believe it would be worth replacing it with something like Seasonic, Antec, Evga, or Corsair.
