Fx-8320 overclocking stable vcore?
Fx-8320 overclocking stable vcore?
Yesterday night I set my AMD fx-8320 to 4.0 GHz with a voltage of 1.6v. I was curious about whether that’s safe, especially since at 4.0 GHz it only reaches around 617 average in Cinebench R15 and I ran it multiple times with PRIMA 95—it performed well now. I’m wondering why the voltage is so high. I plan to go above 4.0 GHz, but I want to confirm if 1.6v is acceptable for the cooler Master Hyper 212 EVO. I just reapplied thermal paste, and it wasn’t old or blackened. Temperatures stayed below 55°C under maximum load.
Consider modifying the LLC parameters. I noticed the BIOS sets them to auto by default; I suspect Gigabyte might use a percentage method. Try beginning at 110% without changing the voltage, or follow any available adjustments in the settings. 1.46 works as long as temperatures remain stable.
increasing the voltage then adjusting the clock isn't the best approach. it's better to raise the clock until it becomes unstable, then slightly increase the voltage. this helps maintain the lowest possible temperature for that speed. for example, my 8350 default voltage was 1.3625, but I discovered the lowest stable voltage at the stock clock was 1.31825. i used a bit more than that to leave extra voltage for my CPU chip. when I returned to the 1.3625v defaults and gradually increased it, i achieved stable speeds around 4.5ghz (the default was 4.0ghz). this way, without putting extra strain on the CPU, i gained an additional 500mhz. of course, raising the voltage further increases speed but also adds more heat and power consumption.
Maxwellmelon suggests a different approach when increasing voltage. Instead of adjusting the clock first, it’s better to raise the clock until it becomes unstable, then increase the voltage slightly. This method helps maintain the lowest possible temperature for that speed. For reference, the default voltage for my 8350 was 1.3625, but I discovered the most stable voltage at a stock clock was 1.31825. I reserved a larger margin of extra voltage for my CPU chip. When I returned to the 1.3625v setting and gradually increased it, I achieved stable performance at around 4.5ghz (the default was 4.0ghz). This way, without putting extra strain on the CPU, I gained an additional 500mhz. If I raise the voltage further, I can increase speed but at the expense of more heat and power consumption.
I usually start with the clock, but I found it unreliable. I tried 4.4 and it didn’t work, then switched to 1.6 and still couldn’t confirm stability. I went back to 4.0 to test, and it worked—now it’s stable. When I return home, I plan to push it further until a crash occurs, then look for a stable setting. It’s unusual since each chip behaves differently; some need only 1.4v at 4.5ghz, while others require more voltage. But at least I know it won’t overheat, which is important given my budget motherboard (GA-78LMT-USB3) limits me to 1.3, 1.4, 1.6, etc., and I can’t set a custom value.
Consider modifying the LLC parameters. I noticed the BIOS sets them to auto by default; Gigabyte might use a percentage method. Start with 110% without changing the voltage, or follow any available adjustments in the settings. They can assist in fine-tuning your OC without additional voltage choices. A value of 1.46 works as long as temperatures remain stable.
