Instability during overclocking without heavy workloads
Instability during overclocking without heavy workloads
If you plan to overclock, you must turn off Turbo. You activate Turbo during your overclock, then let it turbo again when under load. =Crash.
What kind of stress test are you running? I don’t like long artificial tests—just a 2-minute run is enough.
My 9900k runs at 5.0 across all cores, reaching about 175°F with the H100i water cooling and 2 minutes of P95.
What is the baseline voltage? Or what is it referred to in BIOS? I noticed I can ask for adding voltage, but I’m unsure which one I’m increasing. Also, the Load line prompts me to specify a C-State for calibration, probably expecting a lower state such as C3. I will turn off turbo; thanks! I’ve been using Prime95. I was advised that 30 minutes is sufficient so the loop fluid reaches its optimal state for better thermal insight, but unfortunately after around 8 minutes the wattage doubles without any change in clock speed, making it difficult to manage temperature. I’m currently around 80°C at 1,300 rpm on a 240mm AIO under full load. In gaming setups it stays near 60°C, with occasional spikes up to 85°C, which is unusual.
Alright everyone, here’s what I changed.
I turned off ASUS Multicore enhancement, changed CLL to C-State 3, set CPU C-States to Auto, kept Turbo enabled (things are fine without altering it) and adjusted the V-Core to adaptive with an offset of auto.
I’m not sure what those settings do or how they stop my CPU from reaching high voltages, but here’s what I observed.
My power consumption is lower overall. I had to push my limits to achieve the results, but there were no issues.
At 4.7Ghz my V-Core settled at 1.18V. At 4.8Ghz it reached 1.219 and stayed stable. My clock speed remains at 4.8Ghz all day without dropping. During stress tests, around 5 minutes I saw a blue screen. Unless the cores automatically slow down when idle and I stop the blue screen, I’m not sure this is significantly better than my current setup.
Auto offset adjusted to a small positive value or Load Line raised again. Likely insufficient voltage for 4.8Ghz under heavy load (though it should self-regulate). Keep voltage below 1.3. With MCE off, the system now employs standard boost configurations rather than boosting all cores.
