The ECS UEFI interface provides eight types of access to files. Users can save or read their preferred settings, thereby saving setup time.
Above are the some of the main screens of the Z77H2-A2X UEFI with more abundant options and features than before.
When the Z77 is overclocking, it can only match 3770K or 3570K. Based on the CPU characteristics and heat dissipation environment it is possible to start overclocking.
The timing parameters may also be adjusted based on the DDR3 characteristics, and voltage can be increased to 1.6 - 1.65V to improve stability.
This time, ECS has made significant progress in terms of overclocking ability and stability of the Z77, and this should be encouraged.
CPU: Intel Core i7-3770K
Motherboard: ECS Z77H2-A2X
DRAM: CORSAIR DOMINATOR-GT CMT16GX3M4X2133C9
VGA: Intel HD Graphics 4000 / PowerColer 7970
HD: SanDisk Extreme 240GB
POWER: CORSAIR AX650W
Cooler: CORSAIR Hydro Series H100
OS: Windows7 Ultimate 64bit
CPU 99.8 X 47 => 4689.13MHz (Turbo Boost and C1E turned off.)
DDR3 2394.6 CL10 11-11-28 1T
Intel HD Graphics 4000 1150MHz
Hyper PI 32M X8 => 12m 5.526s
CPUMARK 99 => 739
Nuclearus Multi Core => 32969
Fritz Chess Benchmark => 36.69/17612
CrystalMark 2004R3 => 372413
CPU => 9.47 pts
CPU (Single Core) => 1.99 pts
Running Time => 4m 02s
x264 FHD Benchmark => 27.8
PCMark Vantage => 26265
To evaluate CPU performance, at the same clock speed, both the 3770K and the 3570K are almost the same in terms of single-line performance data.
The 3770K has the advantage of support for 4C8T and HT, so multitasking effectiveness is as much as 20% higher.
In multitasking performance, the Ivy Bridge architecture is about 10 to 14% higher compared with the previous generation Sandy Bridge architecture.
For the above-mentioned overclocking performance, the vast majority of software gets very high marks, and in multiple-application environments, performance can be very good.
DRAM Bandwidth Test
DDR3 2394.6 CL10 11-11-28 1T
ADIA64 Memory Read - 24122 motherboard/s
Sandra Memory Bandwidth - 30124 motherboard/s
MaXXMEM Memory-Copy - 27163 motherboard/s
DDR3 2594 CL10 11-11-28 2T
ADIA64 Memory Read - 24399 motherboard/s
Sandra Memory Bandwidth - 31868 motherboard/s
MaXXMEM Memory-Copy - 27807 motherboard/s
Thanks to the Ivy Bridge architecture, the Z77H2-A2X can easily reach the DDR3 2400 -- 2600 level.
This high clock speed has not been easy to achieve on the Intel platform, and the new structure provides a significant improvement in DDR3 performance.
Following these two clock comparisons, it can be seen that the DDR3 2400 1T clock has high bandwidth performance.
If the DDR3 2600 2T is pulled up for a performance increase, there isnít a big improvement,
and if the DRAM I had on hand wasnít such high quality, sometimes it might have been worthwhile to lower the clock a bit and use the 1T at a lower parameter for decent performance.
