Help With AMD FX-8350 OC!
Hey! I'm trying to push my CPU to its best performance and have a quick question: based on what you're currently running—4.5ghz at 1.39V with a stable 45°C—I think I can get it even higher when overclocking. You mentioned you have two new case fans (exhaust and intake), and I'll link them later. With your existing setup (FX-8350, GTX 960, 212 Evo, Gigabyte 970-a) and the fans you're planning to add, what speed do you expect your CPU to reach during overclocking?
At around 1.4v the FX CPU performs well in terms of heat generation after being overclocked to 4.5Ghz speed. When you reach approximately 1.46v to 1.5v, the CPU heat increases noticeably. Even with an aftermarket cooling system in place, temperatures rise significantly at this stage. If you're using a quality motherboard equipped with robust overclocking capabilities and proper CPU cooling, the situation improves. Adding two extra fans would further help manage the heat. Between 1.40v and 1.46v, you should be able to achieve around 4.8Ghz with the FX8350. At about 1.5v, applying additional voltage to maintain stability under load becomes necessary. Consider investing in a water cooling solution for optimal performance. I’ve experienced stable operation at up to 4.9Ghz during stress tests, using a Corsair H100 with multiple intake and exhaust fans. Running at roughly 48°C under load, this setup proved reliable. My recommendation is to adjust the core voltage in steps of about 0.250Mv once you reach around 1.4v, provided your motherboard supports such fine adjustments, and then perform load tests regularly.
Shaun explains his experience regarding CPU performance and heat management at different overclocking speeds. He notes that at around 1.4v, the CPU handles heat well when boosted to 4.5Ghz. However, between approximately 1.46v and 1.5v, the temperature increases noticeably, even with cooling solutions. He mentions that exceeding the recommended voltage, such as 1.6v, can cause damage and significantly raise heat output. He recommends using a quality motherboard with strong overclocking capabilities and additional cooling fans. He shares his own testing results, showing stable performance up to around 4.8Ghz with a Corsair H100 setup, and suggests adjusting core voltage in small increments if needed for stability. He concludes by asking whether reaching 1.4V with proper adjustments is safe, especially considering the risk of exceeding 1.5V.
1.4v or 1.45v can achieve around 4.7Ghz stability.
4.8Ghz to 4.9Ghz might cause the FX CPU to show some stress during a test.
It also depends on whether you have a high-quality FX-based CPU with a good silicone substrate.
Each FX 8350 CPU has slight differences in overclocking potential and applied voltage.
One might reach 4.9Ghz while another could only hit a maximum of 4.7Ghz with the same voltage.
Sometimes it's just a matter of luck.
