CPU 100.3 X 46 => 4601.24MHz(Disable Turbo Boost and C1E)
DDR3 2401.2 CL10 11-11-27 1T(Enable XMP mode)
Hyper PI 32M X8 => 12m 25.166s
CPUMARK 99 => 725
Nuclearus Multi Core => 32856
Fritz Chess Benchmark => 36.22/17384
CrystalMark 2004R3 => 365211
CPU => 9.35 pts
CPU(Single Core) => 1.96 pts
Running Time => 4m 01s
x264 FHD Benchmark => 27.3
PCMark Vantage => 24906
After OC, 3770K single thread performance increases 17~18% and 4C8T full speed performance increases 17~19%.
If we compare 3770K to 2700K, 4.6GHz 3770K performance is close to 4.8GHz 2700K.
This is Ivy Bridge new structure strength.
DRAM Bandwidth Test
DDR3 2401.2 CL10 11-11-27 1T
ADIA64 Memory Read - 23337 MB/s
Sandra Memory Bandwidth - 27784 MB/s
MaXXMEM Memory-Copy - 27482 MB/s
As default CPU clock, LGA 1155 Sandy Bridge can achieve DDR3-2133
LGA 2011 Sandy Bridge-E can reach DDR3-2400.
You can see the different max DDR3 frequency in same Sandy Bridge memroy controller.
This time, LGA 1155 Ivy Bridge can achieve DDR3 2400~2666 up.
Ivy Bridge memory controller makes the best standard of high frequency high performance.
Temperature (Room Temp. is around 30˚C)
Enter to OS Desktop - 34~40
CPU Full Speed by running LinX - 77~83
3770k temperature increases 6~12 when entering to OS desktop and 10~23 as full speed.
If comparing to default and OC 4.6GHz, the increased temperature is in acceptable range.
As 22nm manufacturing, the temperature is higher than SNB.
It may cause by Intel first using 3D transistors technology. This new technology makes 22nm temperature is not lower.
The temperature performance is a fly in the ointment.
Enter to OS Desktop - 64W
