Hi, I am new in pc building, as per research the max turbo frequency of my processor is 3.30 GHz, I only achieve 3.08 GHz as show below. By the way I already installed a new Cooler on that photo and It's 10c to 12c cooler than stock Intel's cooler. My question is, Is it still not properly cooled that's why it doesn't reach the max turbo frequency? Or if enough, is there any way to reach the said clock speed? Thank you :ange: Will greatly appreciate your suggestions

By the way below is my system specs:

Processor: Intel Core I5 6400
Motherboard: ASUS H110M-D D3
RAM : 8 GB @ 1600 MHz
Cooler: Cooler Master Blizzard T2 Mini.

Max Turbo for I5-6400 is 3,1GHz for 3 or 4 cores and 3,30GHz for 1 or 2 cores. In practice, the one that counts is the 3.1GHz

My recommendation is that you leave it that way. The difference with 3.1GHz is so small that it is not worth taking any risk.

The explanation of 3,08GHz is the following: The frequency 3.1GHz (or 3100 MHz) is the product of two factors: the BCLK and the multiplier. The BCLK is 100 MHz for a long time and the multiplier, in this case is 31.

The motherboards, at high load, can not exactly maintain the BCLK at 100. In your case it is 99.35.

In some motherboards you can slightly modify the BCLK upwards (101 or 102) to get a very light OC.

This can have some unwanted side effects and I would not recommend that...

So I am achieving the max Boost. Got it! Thank you @gingerrankin
