FX8350 @ 4.6ghz OC
FX8350 @ 4.6ghz OC
Hey Everyone,
Just starting out with OC'ing for the first time. My current setup is 4.6ghz with a voltage of 1.40. I ran a quick prime95 test across all 8 cores for 20 minutes. Tonight I plan to do a longer stress test, but so far the voltage and ratio adjustments have only let me run 10-15 minutes of stress.
Thermal Margin minimum is 14°C. Does this look like a solid OC?
Gear up: Noctua D15, Asus Sabertooth R2, 32gb RAM at 1866 MHz.
62'C is the upper limit AMD engineers consider safe, clearly a cautious figure. The actual secure range lies near the mid-60s. If core features are active, the chip may drop to around 70'C.
Yes, you can apply load line calibration (LLC) to prevent voltage fluctuations and reductions, which helps lower the maximum temperature. Choosing a medium or high setting rather than extreme values ensures the motherboard maintains steady voltage for the CPU.
In the end, air cooling will reach its limit around 1.45 volts and 4.8Ghz with an 8350 on air, possibly slightly lower at both points—this is what you should expect. Liquid cooling could push performance further.
The voltage seems a bit high. I have an 8370 that isn't overclocked, running at 4.3Ghz with 1.260 Volts. You might want to reduce the voltage, which can help lower temperatures. Also, assuming you're using OverDrive to track temperatures, install Open Hardware Monitor to check the socket temperature. The maximum socket temperature is 70°C, and the core temperature should ideally stay below 55°C for better longevity.
The voltage seems a bit too high for the setup. You have an 8370 that isn't overclocked, operating at 4.3Ghz with 1.260 Volts. Consider reducing the voltage, as it might help lower temperatures. Also, assuming you're using OverDrive to track temperatures, install Open Hardware Monitor to check the socket heat. The maximum socket temperature should be around 70°C, while the core temp should stay under 61°C (you might want to keep it below 55°C for better performance).
I saved CoreTemp and it shows my VID as 1.44v, but in my BIOS the CPU voltage is listed as 1.40125. Are VID and CPU voltage actually the same here?
The images you shared suggest whether a 4.6ghz OC is within your safe range. Would it be feasible to reach 4.8ghz? I’m uncertain about the best approach right now, as I’m currently experiencing a maximum temperature of 54°C. For an AMD 8350, I’ve heard the 61°C mark is ideal. Are there any BIOS settings you’re aware of that could help lower temperatures? Or would switching to liquid cooling be the only way to achieve 4.8–5.0ghz? I’m also not sure if I’ll ever hit such high temps while gaming, so pushing to 4.8ghz might be a stretch. Any guidance would be greatly appreciated. Thanks!
AMD engineers consider 62°C the upper limit for safe operation, but the truly secure range lies near the mid-60s. If core features are active, the processor will likely slow to around 70°C.
Yes, applying load line calibration (LLC) can help prevent voltage fluctuations and temperature spikes, reducing the maximum temperature you can safely reach. Choosing a medium or high setting rather than extreme values will encourage the motherboard to maintain a steady voltage for the CPU, improving stability.
In the long run, air cooling will reach its limits—approximately 1.45 volts and 4.8GHz with an 8350 processor, possibly slightly lower on both metrics. Liquid cooling, however, can safely support up to 1.55 volts and 5+GHz. Custom loop cooling can even push performance further.
My 8320 model now operates at 5GHz with 1.56 volts using a H100 240mm liquid cooler. I previously used an 8350, but the ASUS board failed and the CPU was damaged. It ran at 5.2GHz, and it’s currently in RMA—expected to arrive soon.
When overclocking with liquid cooling, the motherboard’s VRM is the most critical part to maintain airflow. If these lose cooling in an overclocked setup, they’ll overheat quickly. With air cooling, the VRMs receive airflow from the CPU cooler, but switching to liquid removes that flow, requiring an extra 80mm CPU fan to compensate.
In the image, the red circle marks the VRMs—keep them cool at all costs. If you can feel the heat, it’s a sign they’re struggling. Test with your finger at full load; they’ll burn quickly under stock conditions, but with proper airflow, you can push performance further.

@TheMastererr - Thank you for the detailed information! I found it really useful. I still have one more question for you. In your previous message, you highlighted those two metal heat coils on the motherboard. Could you kindly review this image? http://imgur.com/a/EdmAb - you might see a 120mm fan on the left side near one of those heat coils. Do you think this could cause any issues? I was considering it would be fine since I lowered the middle 140mm fan slightly to direct airflow toward that heat coil. What are your thoughts?
