Need help Overclocking Fx 8350
Need help Overclocking Fx 8350
MoBo: Asus M5a97 Evo R2.0
CPU Cooler: CM Hyper Evo 212
CPU: Fx 8350
I was thrilled when I got my 8350, planning to boost it to 4.5Ghz and keep it there. Before that, I used the Fx 6300 and managed to push it to 4.1Ghz simply by adjusting the CPU ratio to 21 (maybe I don’t recall the precise figure). It performed well and never caused any issues.
However, the 8350 presented a completely new challenge. I experimented with various configurations, consulted numerous guides—including this one here:

And watched a video at:

So far, nothing seems to work. I managed to achieve a stable 4.3Ghz clock at around 1.3V using the forum guide, but the temperatures remain too high.
When my PC runs with default settings and no overclocking, core temps sit around 45°C during Prime95 stress test and drop to about 16°C when idle. But once I start overclocking—keeping the CPU at 4.0Ghz and 1.275V—the temps climb past 60°C. That 4.0Ghz setting is just the base clock speed.
Appreciate your assistance.
Verify your cooler's fitment, the EVO should comfortably handle around 4.5GHz under voltage near 1.4V. You'll likely be pushing 4.3GHz with a maximum of 1.36-1.38V, and temperatures shouldn't exceed 55°C during that. Ambient conditions and case airflow are crucial factors here. Apply the thermal margin from AMD overdrive when stress testing to gauge temperatures.
You might have received a subpar silicone TSHRJAIN. Verify if the CPU features a Vishera core by running Cpuz. Occasionally, it's simply a matter of luck with the silicone CPU selection. You could attempt sending the CPU back, stating it isn't functioning properly and requesting a replacement. Alternatively, you might receive a CPU with a superior quality silicone base that enables higher overclocking.
Keep in mind that increasing core count generally requires raising the core voltage. Aim for at least 1.45 to 1.46 volts if targeting a clock speed of 4.6GHz. Using a base frequency of 200Mhz with a multiplier of 23, manually set the core voltage without allowing the BIOS to adjust it automatically.
If you encounter difficulties reaching higher frequencies without generating excessive heat at that voltage, it suggests a subpar CPU silicone. With a Prime 95 chip, performance should remain stable between 60c and 65c when paired with an Evo 212 and medium fan speeds. Maximum sustained temperatures are around 78 to 79°C.
Verify your cooler's compatibility with the Evo, it should comfortably handle around 4.5GHz under voltage near 1.4V. You'll likely need to push up to 4.3GHz with a maximum of 1.36-1.38V, and keep temperatures below 55°C during operation. The surrounding environment and case ventilation are crucial factors. Take advantage of the thermal margin in AMD overdrive for accurate temperature readings during stress tests.
