Overclocking Analysis of the Gold-Themed ECS Z77H2-A2X Motherboard

Intel has just launched the Ivy Bridge platform, and the price seems to be positioned in middle to high range of the desktop market.
The high-end Z77 Ivy Bridge chipset has also become the main objective for performance among all of the motherboard brand competitors.
While in recent years ECS has mainly focused on the OEM business, in the last few years, the company has been more active in launching its own brand of motherboard products.
ECS has launched four new products based on the ATX Z77, together with about four products based on the H77.
Currently, the ECS product line has a wider range of selections for the Ivy Bridge platform than before.



High-end motherboards often appear in colors such as black, red, green, orange and white, yet the ECS Z77 comes in a very rare color.
From the website information, it seems that the Z77H2-A2X and the Z77H2-AX both emphasize the use of gold as their color.
The other three ECS Z77 products are almost the same as earlier products with black PCBs that are supplemented by gray and white versions in the entry-level Z77H2-A2X,
which is ECS’s mid-level Z77 motherboard model, and the highest level product is the Z77H2-AX.

The ECS Z77H2-A2X
Besides the black PCB, the first thing you see is that other parts of the system almost all have a gold glitter.
Even the solid-state capacitors and inductors are gold, and this design really makes a unique impression in the hearts of users.


Gold 4Ever is the main appeal, including the golden quality, the golden stability, the golden heat dissipation and the golden appearance.
But it is unclear whether the company is promoting these standards, because in some situations, the user only has this impression after using the products for a long time.


Accessories Included
English user manual, quick-start manual, golden IO panel, driver software CD
SLI bridge, protective plastic cover for IO ports, mobile connect wireless.


SATA Cable, Front USB 3.0 Panel

The large gold heat-dissipation module shows an emphasis on providing better cooling capacity.
If gold had been used for the color of the heat pipe in middle, the overall appearance would be more consistent.


The heat sink for the Z77 chipset is not small and the spatial design is also good.
The special characteristic of the Black Extreme name printed on the high-end ECS series is that an orange pattern will be displayed as the temperature rises to a certain range.


The pins for the LGA 1155 CPU use a 15μ gold connecting material,
which is also used for the DDR3 DIMM to emphasize the provision of materials that on average have more than three times the oxidation resistance,
heat resistance and scratch resistance of ordinary materials.


The main view of the ECS UEFI shows four graphical interface functions.
In total, 10 different languages are supported including traditional Chinese and simplified Chinese.


Advanced Interface
M.I.B X
The main choices are for CPU and DRAM functions, clock speed, parameters or voltage settings.

Voltage Details
CPU Voltage +0.010 -- +0.630 V
AXG Voltage +0.010 -- +0.630 V
IMC Vlotage +0.011 -- +0.945 V
DIMM Voltage +0.010 -- +0.630 V
System Agent Voltage +0.010 -- +0.630 V
PCH Voltage +0.010 -- +0.630 V
CPU PLL Voltage +0.010 -- +0.630 V


The CPU multiplier default is 47, or in other words, 3770K for 4700MHz operation
The Graphics Core Ratio Limit is the clock speed of the CPU’s internal GPU
The 23 algorithm is 23 X 50 => 1150MHz, and the figure shows the default 3770K clock for the internal HD 4000


DDR3 Setting Page
Supporting XMP technology, the DDR3 clock default is 2400
The main parameters are CL10 11-11-28 1T


In the Z77H2-A2X, ECS has opened a lot more DDR3 parameters than in their own X79R-AX


Page with CPU information and related technology
You can choose to open a few CPU cores.
I personally am accustomed to turning off the power saving C3/C6 and C1E in low-bandwidth overclocking mode to find the best settings.
