Want to customize your FX 8320? Here are some ideas.
I would like to observe the load voltage displayed in cpu-z while prime is active. Both displays indicate idle voltage is quite low. Your board uses the same VRM configuration as the ud3p, running an [email protected] at 1.33v (significantly below stock). I previously achieved 4.6ghz at 1.38v, which remains lower than the stock turbo voltage. This will likely require trial and error, depending on the chip—your voltage is set to auto and should rise automatically with higher clocks. The gigabyte boards are particularly adept at handling this automatically. You might want to check the amd overdrive thermal margin readout for prime load temperatures to ensure they stay within specifications. It’s safe to experiment with 4.2/4.3; 4.4gh tends to be the threshold where voltages change on almost every chip I’ve tested.
Divide by 10 and halve the frequency so 4.2GHz equals a 21 multiplier. It needs to be noted that your load voltage is extremely low. This could indicate a very well-binned chip or possibly vdroop occurring under load, though stability still holds. I’m unfamiliar with the aio cooler, but it seems to manage temperatures well. I recommend starting at 4.2ghz, maintaining stability, then increasing by 0.5 multipliers (100MHz) in steps if you’re not aiming for extreme overclocks but want the best performance possible at low voltage. There might be a threshold where it stops working at 4.3/4.4GHz due to the very low load voltage. If this occurs and you wish to continue overclocking, keep the voltage unchanged and adjust the LLC (loadline calibration) setting to a higher standard value, which will raise the voltage automatically only under heavy loads.
For me, anything above 10c in the thermal margin boxes during overdrive while stress testing is completely acceptable. (actually good)
This provides substantial temperature tolerance for everyday and gaming scenarios.
adjusting the multiplier to x21 brought my PC back online after a minute in Prime, with temperatures near 45°C; I believe this wasn't due to overheating. Then I changed it to 20.5 and encountered errors in Prime (http://imgur.com/a/64dzu). I ran Prime three times to verify, and once it displayed SUM warnings before stopping the worker.
