CompuTronix: aleichliter, Your Vcore is too high. Maximum recommended Vcore for 32 nanometer processors is 1.35. Voltage drives Power (Watts) which drives temperatures, and Hardware Monitor isn't always accurate. Use Core Temp to monitor your Vcore and Watts, and of course your Core temperatures. Also, do NOT run any versions of Prime95 later than 26.6. Here's why: Core i 2nd through 6th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.9, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the utility AIDA64 shows similar results. Since 2nd Generation Sandy Bridge processors have a soldered Integrated Heat Spreader and a significantly larger Die than 3rd through 6th Generation processors, they are somewhat less affected by AVX code. Nevertheless, please download Prime95 version 26.6 - http://windows-downloads-center.blogspot...5-266.html Run only Small FFT’s for 10 minutes. Use Core Temp to measure your temperatures - http://www.alcpu.com/CoreTemp Your Core temperatures may test 10C lower with v26.6 than with v28.9. You should read this Sticky: Intel Temperature Guide - CT Do either of these include the setting to disable automatic voltage setting? I have it set to 1.35 by the way.
From the pictures it seems you should disable auto for CPU voltage frequency.
From the images it seems you should disable auto for CPU voltage frequency. The only other choice was manual—what value should that be set to? I should also note that with default settings it was at 3.7 GHz and idle temperatures were roughly 25-30°C. However, in this case the turbo ratio was fixed at 37 and the voltage around 1.00. This is unusual since with overclocked settings the ratio decreased to 16x while maintaining similar voltage, but the idle temps rose to about 40°C or more.
Manual is accurate. The output will differ but remain around 1.30 volts when adjusted.
