The radiation fin for Z77?s chipset is of long-shape design.
In addition to the unique appearance, it is also labeled with PURO Hi-Fi.


O.N.E calibration page of BIOSTAR UEFI interface
The frequency multiplication of the CPU Ratio is 45, i.e. 3770K will be operated by 4500MHz


Graphics Core Ratio Limit is the frequency of the built-in GPU
The algorithm of 23 is 23 X 50 => 1150MHz. In the figure below, it adopts the default frequency of built-in HD 4000 for 3770K.
DDR3 frequency is set as 24, namely DDR3 2400.


For DRAM frequency and parameter settings, generally, smaller value leads to higher performance.
Set it as DDR3 2400 CL11 12-11-28 2T, and adjust other detailed options to optimal setting values.
The user can increase the frequency and adjust the parameters based on the DDR3 property, so as to increase DDR3 bandwidth.


Voltage page
Four CPU VCore Modes are included, i.e. SPEC Volgate/Auto/Offset Mode/Fixed Mode
CPU VCore Offset -0.200~+0.370V
CPU VCore Fixed 1.000~1.790V
In terms of the purpose of overclocking, the major change here is the CPU voltage.
In the sample figure, the CPU Vcore is fixed as 1.280V. Making slight adjustment based on the radiation ability and CPU property are two major foundations for overclocking CPU.


This page can adjust the shared capacity needed by the HD 4000 built in 3770K.


CPU Smart FAN can control the rotating speed based on the CPU condition.


PC Health Status
The CPU temperature detected here is higher, while the wind temperature felt from the radiator or the detected temperature by OS temperature detection software will be lower.


This time the common and affordable CPU radiator is used, and the 3770K overclocking to 4.5GHz is set stably.
Install 4DIMM DDR3 2133 and overclock it to 2400 2T. The capacity of DRAM is 4G X4, namely 16GB in total.
Hi-Fi Z77X is equipped with better radiator and 2DIMM DDR3, which can also achieve the overclocking performance of 4.8GHz / 2600.
I only intend to test the overclocking in different ways, providing more information to the users who need.

Test platform
CPU: Intel Core i7-3770K
MB: BIOSTAR Hi-Fi Z77X
DRAM: CORSAIR DOMINATOR-GT CMT16GX3M4X2133C9
VGA: SPARKLE GTX570 SLI
SSD: CORSAIR Performance Pro Series 256GB
POWER: CORSAIR AX650W
Cooler: XIGMATEK HDT-S1283
OS: Windows7 Ultimate 64bit


Intel Core i7-3770K overclocking performance
CPU 100 X 45 => 4500MHz 1.280V
DDR3 2400 CL11 12-11-28 2T 1.608V

Hyper PI 32M X8 => 12m 57.381s
CPUMARK 99 => 708
