Since Intel launched Sandy Bridge in Jan 2011, it’s been a year.
In April 2012, Intel released LGA115 socket, code name is Ivy Bridge.
CPU manufacturing from 32nm 2nd Core I improves to 22nm 3nd Core I and some new technology.
The most high end chipset is Z77 instead of Z68.
Simultaneously, mid-end chipset is H77 to replace H67. Also B75 is for SMB. The price is higher than H61.
Z77 position is same as Z68. It integrates all new features.
It owns GPU output and CPU/GUP overclock options. It’s for high performance.
Z77 is also native support USB3.0 plus native SATA3 which is same as Z68.
Z77 complements the new generation I/O spec. However, it would be better to support more SATA3 Ports.
This guide is test with Z77 mid-end range product - GIGABYTE Z77X-UD3H WiFi.
GIGABYTE started this design from X79. White background looks better.
Accessories
The WiFi means this model bundles BT4.0 and WiFi PCI-E card.
Lower-Right is two different USB devices. WiFi make PC location be more flexible.
As more mobile devices be more popular, now your PC can link with smart phone or tablet through BT and WiFi.
GIGABYTE Z77X-UD3H position is replacing Z68X-UD3H.
Z77 UD3H plus WiFi is only 10USD more than Z68.
However, it bundles exclusive PCI-E BT4.0/WiFi card to have better C/P.
Main color is black and heat sink is blue. The harmonize colors are good.
Intel Smart Response and Lucid Virtu GPU are still key functions of Z77.
Lower-Left Corner
3 X PCI-E X16 support 2-Way AMD CrossFireX/nVIDIA SLI technology
When using Ivy Bridge CPU, the bandwidth is Gen3 X16 + X8 + X4
3 X PCI-E X1
1 X PCI
LAN chip is Atheros GbE LAN
Audio chip is VIA VT2021 supporting 7.1 channel and High Definition Audio technology
Design in Taipei
Lower-Right Corner
2 x White SATA, by Z77, support SATA3
4 x Black SATA, by Z77, support SATA2
It supports hybrid RAID 0, RAID 1, RAID 5 and RAID 10. The max performance is decided by installed SATA devices.
2 x 64 Mbit flash, Dual BIOS double protection, Debug LED
Upper-Right Corner
4 x DIMM DDR3 support 1333/1600/1866/2133/2666(OC). The max DDR3 capacity is 32GB.
It supports Extreme Memory Profile. Next is 24-PIN power connector and front USB 3.0.
Red Power button, black Reset and blue Clear CMOS buttons.
The part below are 7 onboard voltage read points for accurate real-time voltage reading.
IO
1 X PS2 Keyboard/Mouse
1 X D-Sub / DVI-D / HDMI / DisplayPort
1 X S/PDIF Optical Output
6 X USB 3.0/2.0(Blue)
2 X eSATA 6Gb/s(Red)
1 X RJ-45 LAN
6 X Audio Jacks

mSATA SSD slot supports small capacity SSD.
It can work with Intel Smart Response to enhance system performance. However, RAID 5 will be disabled.
Heat-sink cutting and color are good texture.
System Configuration
CPU: Intel Core i7-3770K
MB: GIGABYTE Z77X-UD3H WiFi
DRAM: CORSAIR DOMINATOR-GT CMT16GX3M4X2133C9
VGA: Intel HD Graphics 4000
HD: Intel 520 Series 120GB
POWER: CORSAIR AX650W
Cooler: CORSAIR Hydro Series H60
OS: Windows7 Ultimate 64bit
First of all, I test in CPU default mode.
Default Setting
CPU 100 X 35 => 3500MHz (Enable Turbo Boost and C1E)
DDR3 2134.2 CL9 11-10-27 2T (Enable XMP mode)
Hyper PI 32M X8 => 14m 10.826s
CPUMARK 99 => 615
Nuclearus Multi Core => 28541
Fritz Chess Benchmark => 30.77/14770
CrystalMark 2004R3 => 318966
CINEBENCH R11.5
CPU => 7.86 pts
CPU(Single Core) => 1.67 pts
FRYRENDER
Running Time => 4m 42s
x264 FHD Benchmark => 23.1
PCMark Vantage => 23265
If we compare3nd Core i7-3770K and previous 2nd Core i7-2700K, 3770K single thread performance is 3~6% higher and 4C8T is 10~14% higher.
The main difference is 22nm and 32nm. The frequency are both 3.5GHz and 3.9GHz by Turbo Boost.
As my personal using experience, these 3 generations Core i CPU, each generation has 10~15% performance improved.
DRAM Bandwidth Test
DDR3 2134.2 CL9 11-10-27 2T
ADIA64 Memory Read - 21358 MB/s
Sandra Memory Bandwidth - 27475 MB/s
MaXXMEM Memory-Copy - 23497 MB/s
All new platforms DDR3 performance can divide into bandwidth and max frequency.
For bandwidth, Ivy Bridge DDR3 is similar to Sandy Bridge.
However, the max frequency is improved a lot which I will show you the detail later.

Temperature (Room Temp. is around 30ËšC)
Enter to OS Desktop - 28~34
CPU Full Speed by running LinX - 60~67
As high room temperature, I use CORSAIR Hydro H60 with 12cm high speed fan.
The temperature is not same as past experience. As CPU yield rate improving, it may relate to 3D transistors.
Power Consumption
Enter to OS Desktop - 34W
CPU Full Speed by running LinX - 106W
3770K enters to OS desktop is 11W lower than 2700K, about 25% lower.
Full speed is 3W more than 2700K, about 3% up.
3770K power consumption is lower as entering to OS desktop. For full speed, the power consumption is similar to SNB.
OC Test
Let’s check UEFI related interface first.
CPU Clock Ratio set to 46, 4600MHz.
Enable X.M.P. to set DDR3 to 2133 automatically.
System Memory Multiplier set to 24, DDR3-2400 by DDR3 quality.
Advanced CPU Options
You can define individual CPU Core ratio or decide how many Core to enable.
C1E is power saving technology which is contrary to Intel Turbo Boost. Intel Turbo Boost will rise CPU frequency by different loading.
DDR3 2400 parameters are CL10 11-11-27 1T.
Major three OC voltage range.
CPU Vcore 0.800~1.900V
DRAM Voltage 1.100~2.100V
CPU Vtt 0.800~1.700V
3770K voltage is very low as OC to 4.6GHz. The CPU Vcore is 1.235V.
PC Health Status
GIGABYTE UEFI interface provides 6 languages.
Normally, I spend 3 to 5 days to fine tune all voltage and OC set up.
Ivy Bridge new platform takes me almost 2 weeks to find the balance between CPU and DDR3.
Every CPU and DDR3 quality will impact the OC result. The cooling devices and room temperature will make difference as well.
The value above is based on my personal equipments. 3770K OC CPU 4.6GHz / DDR3 2133 OC 2400.
