FX 8320 and BIOS settings
FX 8320 and BIOS settings
Hello, I’m here to assist with your OC questions. I used stock voltage to clock my CPU to 4.0 GHz and have a few concerns.
My system details are: CPU FX 8320, motherboard Gigabyte 970A-UD3P, 8 GB RAM at 1600 MHz, 212 Evo cooler, running Windows 10.
1. Did I leave the voltages in ‘Auto’ mode? That seems fine.
2. I turned off Core Performance Boost, C1E, C6 and APM. If I need to adjust anything, let me know. Also, will enabling the power saving setting affect my OC?
3. With 1600 MHz RAM, what should be the optimal clock rate and multiplier?
Currently, I’m seeing good temperatures during stress tests (max 45°C), so I might consider increasing them.
Thank you in advance!
You are aware that the FX 8320 cpu's stock frequency should be configured in the BIOS at 3.5 Ghz. Therefore, your standard memory bus speed will be adjusted to 200 Mhz, and the CPU's multiplier in the BIOS will be set to 17.5. Multiplying these together gives a theoretical maximum of 3.5 Ghz or 3500 Mhz. Each subsequent even number increase in the multiplier adds another 200 Mhz to the CPU's clock speed, while every odd increment raises the speed by 100 Mhz. If you aim for a higher clock speed, you may need to slightly raise the voltage through manual adjustments in your BIOS settings for the core voltage.
You are aware that the stock frequency for the FX 8320 CPU should be configured in the BIOS at 3.5 GHz. Therefore, your standard memory bus speed will be adjusted to 200 MHz, and the CPU's multiplier setting in the BIOS will be set to 17.5. Multiplying these together gives 3.5 GHz or 3500 MHz if desired. Each increment of the half number in the multiplier after that will add another 200 MHz to the CPU’s clock speed. Similarly, each increase in the multiplier by half will boost the speed by an additional 100 MHz. If you aim to push the CPU beyond its default settings, you may need to slightly raise the voltage through manual adjustments in your BIOS settings for core voltage. The upper limit you can reach is around 4.3 to 4.4 GHz at the default core voltage. On average, most FX-based CPUs can exceed their factory frequency by at least 800 MHz. After reaching 4.3 to 4.4 GHz, you should consider adjusting the core voltage in steps of 0.250M or 0.500M to increase it gradually. The safe maximum core voltage for an FX CPU is 1.6 volts and should not be surpassed. Maintain it near 1.55 volts. When this voltage is reached, the CPU will heat up more quickly and operate at higher temperatures. The effect depends on your motherboard quality, the chipset (such as AMD 990FX), and the cooling solution you use. It’s achievable to approach a base speed of around 1 GHz through overclocking. However, reaching up to 4.5 GHz is possible depending on the system configuration. 4.3 GHz is typical when using an EVO 212 cooler in air.
