Adjusting OC settings for i9-10900k at 5MHz
Adjusting OC settings for i9-10900k at 5MHz
Hello!
I increased the clock speed of my 10900k to 5ghz. When I play games or work in a DAW with demanding tasks, it handles well, maintaining around 4.8 and 5ghz even when idle, thanks to the constant speed setting. Temperatures stay between 50 and 65 degrees, mostly during idle time since the fans aren’t spinning too much.
However, during a stress test with AIDA64, the frequency drops to 4.69ghz, but AIDA64 claims it isn’t throttling. Could this be normal?
The temperature fluctuations during the test are between 84 and 86 degrees, which seems typical online. I’d also appreciate your insights on this situation.
I’m using a Noctua NH-D15 cooler.
Additionally, I noticed a past issue where the system would run in the mid-70s to mid-80s before games and spike above 100 during stress tests, but after reapplying thermal paste, it stabilized at 84-86.
Looking forward to your thoughts!
Aida64 relies on AVX instructions during testing, which can achieve up to 130% CPU performance, significantly exceeding typical usage levels. This high utilization leads to increased power consumption beyond normal expectations. Prime95 small fft serves as a reliable thermal gauge with the ability to turn off AVX features, offering consistent 100% performance—essentially representing the maximum load under standard conditions. There are games that incorporate minimal AVX support, and only a handful (such as a mod in Skyrim) utilize AVX2, which demands even more processing power. This is still viewed as typical because the CPU would not exceed 100% initially. Therefore, Aida64 and similar applications will generate substantial heat, though this should not be alarming.
You haven't applied an OC to the CPU, but you've increased the Turbo limits. This means the CPU will be restricted to the power and current boundaries set by the Turbo settings for short periods. When you reach that limit, the cores will slow down to preserve performance and efficiency.
For example, if your maximum is 250W, it will stop at 250W whether you have 6 cores running at 5.0GHz or 10 cores at 4.5GHz. This differs from thermal throttling.
With an OC, the changes go beyond just adjusting the multiplier and core count—you also need to modify internal BIOS settings to support the required power output. If you don't do both, you'll likely experience one of two outcomes: a drop in performance during stress tests or issues with booting.
Thank you for your reply!
I see that I've adjusted the core voltage to 1.320, which should be sufficient for 5GHz. Isn't that right?
The remaining two values are set to 1200 (I don't recall what they do exactly, but one is linked to memory exchange in the processor between components, and the other I'm not sure about).
You require significantly more than the listed adjustments. LLC, turbo long/short values, current limits, disable phase controls, disable c-states, Ring voltages, VID, AVX offset, and additional parameters are needed. Simply increasing VCore and VCCIO/VCCSA won't work—multiplying isn't an option, it doesn't ensure stability, and it's not suitable for the CPU overall. Your lack of understanding about your actions is clear. Applying only half an OC won't yield the expected improvements.
This indicates the CPU is functioning as intended with the settings you've set. Increasing voltages without reason can damage the CPU over time and reduce stability. If you need to overclock, make sure you thoroughly understand what you're doing and test properly. Restart your BIOS and run it in stock mode for better performance.
