What Is The Best Sub-$100 Intel Z77 Motherboard? Find Out In Our Roundup!
BIOSTAR TZ77B Overclocking
Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get.
The Intel Core i7 3770K utilizes a Bclk of 100MHz, under full load the Intel Core i7 3770K uses a multiplier of x35 to achieve the final clock speed of 3.5GHz. Since we are using a K series processor which has an unlocked multiplier we will be able to increase the default x35 multiplier to achieve our overclock today. The Intel Core i7 3770K has a turbo multiplier of x39 which will cause the system to run at 3900MHz (100MHz x 39).
I wasn’t able to bring our Intel Core i7 3770k processor quite as high on the BIOSTAR TZ77B as we were able to on previous motherboards. We have typically been able to hit 4.7GHz on our ‘Ivy Bridge’ platforms with complete system stability. Today though, we were limited to 4.6GHz. While it’s wasn’t the greatest overclocker today, it went smooth. With a little more time and tweaking we could quite possibly get higher.
The only settings that we had to modify inside the BIOS were the CPU Turbo Core Ratio which we can see above, and the CPU vCore was increased to +.084V offset which can be seen below.
