The built-in CPU of previous LGA 1156 Core i3/i5 integrated with H55, may not be able to run the DDR3 bandwidth.
However, the new generation LGA 1155 may have addressed this problem with its built-in CPU that begins to retain the architecture performance.
With regard to the Core i platform of Intel built-in GPU, its DRAM bandwidth performance is no longer as good as that of Core 2 Duo.
There is an improvement of over 50% in the bandwidth of DDR3 1333.

There are more limitations for Sandy Bridge in CPU overclocking than ever before.
If only the CPU external frequency is adjusted, then the CPU can operate stably within a range of 104~107MHz.
In terms of overclocking and multiplication, there are only 2500K/2600K integrated with P67 chipset that can realize a drastic overclocking.
As to H67, only a small overclocking of the external frequency can be adjusted,
and the whole frequency after the external frequency’s change to 107MHz, will increase from 2.8 to almost 3GHz.

Temperature performance (room temperature is about 18℃)
During system standby: - 25~33


At full speed of CPU: - 61~64
Intel Burn Test v2.4,Stress Level Maximum


Since the overclocking is only about 7%, there is no big difference in the temperature.
By comparing the default values, the temperature difference during system standby is about 3℃ and this is just about 4℃ at full speed of the CPU.

Power consumption test
During system standby: - 37W
