Unusual temperatures during overclocking of FX-8350
Unusual temperatures during overclocking of FX-8350
I've been attempting to push my AMD FX-8350 to higher speeds by adjusting it all day long yesterday. The only settings that worked for me were 4.4GHz at 1.44VCore. I performed a blend test on Prime95 with the voltage set around 1.4380, but two cores failed after 2:30 hours and another after 5 hours, indicating instability in my overclock. I then raised the voltage to 1.4490, which is the maximum allowed by my motherboard (MSI FXA990-GD65). Recently, I've been running short FFT tests on Prime95 for about 15 minutes, achieving a max temperature of 59 degrees, compared to under 52 yesterday. Is the voltage too high? If so, what adjustments can help stabilize my overclock at a lower setting? My cooler is a Corsair H100i, which might explain why the temperatures felt unusual.
Maximum recommended voltage is 1.5v, maybe that's why MB doesn't let you go any further. In any case, why don't you use AMD Overdrive for monitoring and stability tests ? There's no much use in torturing system with prime95 or any such program geared toward Intel processors.

is also more AMD friendly.
CountMike shared some insights on the topic. The recommended voltage is up to 1.5 volts, which might explain why MB restricts further adjustments. He suggests using AMD Overdrive for monitoring and stability checks instead of tools like prime95 that target Intel processors. He also mentions a link to a more AMD-friendly resource. He notes that setting CMOS reset allows higher values initially but limits them after reboot, making it hard to achieve optimal overclocking performance. He questions why these settings are hidden from users.
Additional configurations should exist for LLC (Load Line Calibration) or any other name on that MB to increase voltage beyond the preset level when necessary conditions arise.
There should also be options for LLC (Load Line Calibration) or whatever name it is called on that board to increase voltage when needed.
