Prime95 errors vcore
Prime95 errors vcore
I've been running the FX-8320 @4.0 for some time without any voltage changes. Today I'm attempting to push it up to 4.1ghz to boost performance. I kept the Vcore constant for about an hour and a half until the eighth core stopped working, which led me to adjust the Vcore in offset mode by +0.006. After that, I performed another stress test with small FFTs, but it crashed on cores 7 and 8 within 1 to 3 minutes due to rounding errors. Does changing the Vcore affect stability? Should I be concerned about the stock Vcore range of 1.3v to 1.4v? My temperatures are normal at 4.1 cores running at 40-45°C in a 60C socket. All other settings are disabled except for C1E, HPC, APM master, and cooling options. My main concern is whether increasing the Vcore is making things more unstable or if I've made a mistake. This is definitely not what I expected.
Navek has been using an FX-8320 @4.0 for some time without needing a voltage boost. Today he attempted to push it to 4.1ghz to enhance performance. He adjusted the Vcore in offset mode by +0.006 after running Prime95 for about an hour and a half until the 8th core failed. The test showed a rounding error on cores 7 and 8 within minutes. He wonders if changing the CPU-NB voltage would help stability during overclocking, or what the situation really is. His stock Vcore is between 1.3v and 1.4v, and his temperatures remain normal at 4.1 cores running at 40-45°C.
Navek has been using an FX-8320 @4.0 for some time without needing a voltage boost. Today he attempted to push it to 4.1ghz to extract more performance. He kept the Vcore constant for about an hour and a half until the 8th core stopped working, resulting in "Final Result was: (********) Expected: (********). That’s when he decided to raise the Vcore in offset mode by +0.006." After that, another stress test with small FFTs failed on cores 7 and 8 within 1 to 3 minutes due to rounding errors. He wonders if adjusting the CPU-NB voltage would help for a more stable overclock, or if something went wrong. His stock Vcore is around 1.3v - 1.4v. His temperatures are normal at 4.1 cores running at 40-45°C in socket 60C. All other settings are disabled except HPC and APM master mode. He is unsure whether increasing the voltage would improve stability or if he has made a mistake. This is his M5A97 R2.0, AMD FX-8320 @4.0 (testing 4.1), Hyper 212 EVO, with RX 480 4GB GPU, G. Skill Ripjaws 2x4 1600 RAM, and he’s considering raising the voltage only until stability is reached. He advises reducing the voltage to prevent further damage if errors continue.
