Z77 high end version also use big surface heatsink. It looks elegant.
It features ultra-thin metal fins, the heatsink provides greater surface area so that quicker heat exchange can occur.

Z77X-UP7 this design is better than Z68X-UD7.
Red button is power button. Two + and ? for adjusting CPU and BCLK. Gear is for BCLK steps switch.
Right hand side is LN2 switch and below has 8 touch points for voltage measurement.

GIGABYTE displayed IR3550 PowlRstage in ComputeX 2012. This new PWM design uses in own mid to high end MBs.
It delivers 60A per phase and lower temperature than former PWM design.
Z77X-UP7 uses 37-phase digital PWM, 32-phase CPU + 2-phase VTT + 3-phase Intel HD GPU.

GIGABYTE UEFI interface provides 7 languages. I remember it seems didn?t support Korean in previous version.

Intel Core i7-3770K default ratio is 35. I set it as 48 to run at 4800MHz.
Enable X.M.P. and this CORSAIR DDR3 auto set to 2400 and CL.

Vcore Loadline Calibration is important feature for CPU OC.
CPU voltage set as 1.350V and Vcore Loadline Calibration is default. When CPU is full speed, voltage will drop around 2 levels.
As the pic, I switch to Extreme and set CPU to 1.350V. It?s 1.356V as standby and 1.368V as full speed.

I set i7-3700K to 1.350V. It can pass all software stalely.
DDR3 voltage is 1.650V as the other key voltage in OC.

Test Configuration
CPU: Intel Core i7-3770K
DRAM: CORSAIR Dominator Platinum CMD16GX3M4A2400C9
VGA: PowerColor AX7970 3GBD5-2DHV3
HD: CORSAIR Performance Pro Series 256GB
POWER: Thermaltake TR2 600W
Cooler: CORSAIR Hydro Series H100
OS: Windows8 64bit

CPU 100.0 X 48 => 4801.5MHz(Disable Turbo Boost and C1E)
DDR3 2401 CL9 11-11-31 1T(Enable X.M.P. mode)

Hyper PI 32M X 8 => 10m 53.985s
CPUMARK 99 => 756

Nuclearus Multi Core => 35398
Fritz Chess Benchmark => 37.79/18137
