Intel 12th Generation Core's mainstream model i5-12400 did not disappoint, performance, power performance is perfect, and now it is found that it still has a lot of overclocking potential.
i5-12400 has only 6 large cores, the frequency is 2.5-4.4GHz, the reference power consumption is 65W, and the maximum acceleration power consumption is 117W, but it does not belong to the K series, so it is locked to multiclock, and it is troublesome to overclock, and it can only be overclocked.
After searching for German overclocking expert Der8auer, it was found that the B660 motherboard was impossible to over-frequency, and the Z690 motherboard only had very few supports, such as Asus's ROG Z690 APEX/HERO, and the BIOS version could not be lower than 0811.
In addition, it is worth mentioning that on the 12th generation Core, the external frequency is no longer associated with the PCIe frequency, that is, it will not be synchronized and overclocked, but it reduces the trouble and reduces the difficulty.

After trial and error, Der8auer overtook the external frequency of an i5-12400 to 130MHz, an amplitude of up to a staggering 30%, and the main frequency reached 5.24GHz.
In order to stabilize, the DDR5 memory frequency and cache frequency must be manually lowered, and the ratio is reduced from 40 to 33.
In addition, the core and cache voltages are increased to about 1.35-1.37V.
Using a similar approach, he also overclocked an i5-12600 to 5.1GHz and increased the external frequency to 116MHz.
After overclocking, the i5-12400 CineBench R20 test multi-core running score reached about 6200 points, which was 33% higher than the 4700 points at the silent frequency!
The average frame rate of Battlefield 2042 is as high as 127FPS, and the lowest frame of 1% also has 100FPS, an increase of 6.7% and 23.5%, respectively.
The average frame rate of "Eat Chicken" is 375FPS, and the lowest frame rate of 1% is 232FPS, which is 13.6% and 19.6% respectively.
However, the cost is not small, the maximum power consumption after overclocking reached 138W, and the core temperature was 96 °C.
