Temperature (Room Temp. is around 30˚C)
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.
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.
Letís 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.
