I adjusted the core ratio to 5ghz yet it continues to operate at its default pace.
I adjusted the core ratio to 50 (5ghz), increased all current and power limits to their maximum, and adjusted the voltage to 1.4v. This setting is considered high by many, but I'm accustomed to running my CPU at 1.4-1.5v without issues. However, when booting into Windows, it still operates at stock speeds. Upon restarting into the BIOS, it indicates it should be running at 5ghz. What's happening? Please clarify, as this might affect its performance.
Without any information to work with, my assumption would be that your system is adjusting to the workload. When there’s no demand, it operates more slowly to save energy or heat. Under heavy load, it will function at the speed you have programmed. To confirm this, you’d likely need to provide a few details:
A screenshot (or photos) of the relevant BIOS settings where you set up the configuration.
A screenshot showing the core speeds for each core in HWiNFO64 or CPUID HWMonitor during a substantial stress test like Prime95 or AIDA64.
I tested it under heavy load with AIDA 64 and it maintained its original speed (4ghz). I discovered a way to resolve the issue by disabling thermal throttling and a few other tricky Intel configurations. Now it runs smoothly at 5ghz, and I managed to lower the Vcore to 1.375 volts without any problems in Prime95 small FFT tests. Thanks.
I'm not foolish, I always maintain my CPU below 99 degrees celsius and I'm using one of the top coolers, a Thermalright IB-E Extreme that's directly mounted on the die. From my experience with previous overclocking, if you precisely set the Vcore voltage, your CPU will start to behave unpredictably and your system will fail before it gets too hot and causes damage. As temperature rises, it demands more voltage to stay stable, which leads to a kind of "thermal throttling." However, instead of the CPU slowing down as expected, it simply crashes. This is due to the way CPUs react to voltage changes at different temperatures, not because of any software issues.
I'm not foolish, I always maintain my CPU below 99 degrees Celsius using one of the top coolers, which is directly mounted on the die and a Thermalright IB-E Extreme. Based on past overclocking experiences, if the Vcore voltage is perfectly set, the CPU can become unstable and the system may crash before overheating damages it. As temperature rises, more voltage is needed to stay stable, leading to a kind of "thermal throttling" rather than actual performance loss. This issue usually stems from the CPU's physical response to heat, not software.
With a decent cooler setup, temperatures should stay under 85°C and avoid thermal throttling. If you're in the high 90s, it suggests a cooling problem—possibly due to poor thermal mounting, inadequate airflow, or case airflow issues.
I'm also using a similar-looking air cooler (Noctua NH-D15) with an i7-9700k, achieving stable 5.0GHz performance and keeping temps below 83°C without throttling.
If you need assistance, just stay calm and keep helping—triggering thermal throttling means the cooling isn't enough for the workload.
In fact, because the T junction of Intel CPU's is at 99 degrees, and they begin throttling around the 80-degree mark, it doesn't necessarily indicate poor cooling. It simply means Intel decided to start throttling earlier than needed. Many laptops operate at 99 degrees Celsius yet still reduce speed in the 80-degree range. Perhaps this is intentional so that performance isn't consistently high for long, and then a noticeable slowdown occurs once the T junction is reached. You're correct that my thermal interface material is very poor (it's a worn graphite pad and it didn't perform well even on new dies), and I was using a weak 900rpm fan. That explains the high temperatures I'm experiencing. This situation will improve once better thermal paste and proper fans are installed.
I'm not naive, I maintain my CPU temperature below 99 degrees Celsius and I'm using one of the top coolers available, a Thermalright IB-E Extreme that's directly mounted on the die. Based on past overclocking experiences, if you precisely set the Vcore voltage, your CPU tends to become unstable and your system may crash before overheating damages it. As temperature rises, more voltage is needed for stability, which can lead to what's known as "thermal throttling." This doesn't mean the CPU is intentionally slowing down due to software—it's a physical response to heat. If your cooler installation is adequate, your CPU should stay under 85°C and avoid triggering thermal throttling. Temperatures in the high 90s usually indicate a problem with the cooler setup—possibly poor thermal mounting, inadequate airflow from the case or cooler, or other issues. For reference, I'm using a similar-looking air cooler (Noctua NH-D15) on an i7-9700k and can sustain 5.0GHz with Prime95 for extended periods while keeping temperatures below 83°C without throttling. If you need assistance, just stay calm. My goal is to help, not to argue. Triggering thermal throttling clearly means the cooling isn't sufficient for the workload. This advice comes from an Intel Temperature Guide: The relevant excerpt states: "Core temperatures above 85°C are not recommended. Core temperatures below 80°C are ideal."
Welcome to Tom's. I notice you've reached out with a question, but it seems you haven't received the answers you were hoping for. That's okay—dissent and discussion are welcome. The issue here is that you're repeatedly sharing personal insults, profanity, and other argumentative remarks. Those posts have been removed, and as a result, your post is now closed.
