After installing my new RAMs, my Overclock settings in BIOS disappeared. My Intel i5 dropped from 4.02Ghz to 2.67Ghz.
Furthermore, I ran a Greenbench 2 benchmark and it came back with a score of 5807, originally 8262.
Can someone teach me or tell me what settings do I need to do in the BIOS to revert back to my original overclocking settings?
I am using Windows 8 64-bit.
My new RAMs are Corsair CML8GX3M2A1600C9B LP Vengeance Memory 8GB 1600MHz CL9 DDR3 Two Module Kit

If you need anything else, please let me know.

You have another problem also...
Your 1600 mhz speed CML8GX3M2A1600C9B DRAM is running at 1333mhz speed.

You need to go into BIOS and put your OC settings back in and change your DRAM speed to DDR 1600........ummm...not sure what to tell you besides that.

Ok I change some things in BIOS. It looks like this now:

Xtreme Phase Full Power Mode : Enabled
BCLK Frequency : 200
PCIE Frequency : 100
DRAM Frequency : 1600MHz
QPI Frequency : Auto

CPU Differential Amplitude : Auto
CPU Clock Skew : Auto

CPU Voltage Mode : Manual
Fixed Voltage : 1.47500
IMC Voltage : Auto
DRAM Voltage : 1.6500
CPU PLL Voltage : 1.9000
PCH Voltage : Auto

Load Line Calibration : Disabled

PCIE Spread Spectrum : Disabled

CPU Ratio Setting : 20.0

Can it go any higher than that? Anything I can change to further boost my system?
I even upgraded my graphics card to GTX 660 Ti SC 2GB
I managed to boost my processor to 4.01Ghz.
