The above is H55M-USB3 BIOS menu introduction.
I set the BIOS as running stable at 200/1600.
You can refer to the setup if your equipments are similar.


Configuration
CPU: Intel Core i5-660 ES
MB: GIGABYTE GA-H55M-USB3
DRAM: CORSAIR DOMINATOR CMD8GX3M4A1600C8
VGA: Intel Clarkdale 733MHz
HD: CORSAIR CMFSSD-128GBG2D
POWER: be quiet E7 Cable Management 480W
Cooler: Mega Shadow(Deluxe Edition)
OS: Windows7 Ultimate 64bit


Default performance
CPU 133 X 25 => 3333MHz
DRAM DDR3 8GB 1333 CL7 7-7-21 1T
GPU 900MHz 128mb

Hyper 4 X PI 32M=> 18m 09.803s
CPUMARK 99=> 550


Nuclearus Multi Core => 13547
Fritz Chess Benchmark => 13.11/6295


CrystalMark 2004R3 => 163715


CINEBENCH R10
1 CPU=> 4813
x CPU=> 11014


PCMark Vantage => 11878


Sandra Memory Bandwidth - 12107 MB/s
EVEREST Memory Read - 9526 MB/s


Intel Core i5-660 default performance is close to i5-661.
The main difference is 3D performance which caused by clock. However, the performance is not big different.
DDR3 performance is the key weakness of Clarkdale platform.
Intel builds in GPU into CPU and this structure lower the memory controllerís performance...
As 32nm Clarkdale CPU and H55 DDR3 bandwidth, itís not much higher than LGA775 or AM3 platform.
