Overclocking MSI X58A-GD65

Greetings to all!
I would like to overlock my computer properly in order to be able to achieve better perfomance in gaming
That is due to the reason I don't want to spend more money to this computer (I have already spent a lot)

My system build is:
Tower: CoolerMaster Cosmos RC-1000
PSU: CoolerMaster Real Power M850
CPU: Intel Core i7 920
CPU Cooler: CoolerMaster V8
Motherboard: MSI X58A-GD65
RAM: OCZ DDR3 PC3-12800 Intel® i7 Triple Channel [3x2GB, 1600 MHZ, 8-8-8-24
SSD: A-Data X25 80GB by Intel (Model: SSDSA2MH080G1GN) [Sata 2]
VGA: Sapphire Radeon HD4870 1GB
HDD1: Western Digital Caviar Black 1TB (WD1001FALS) [Sata 2]
HDD2: Western Digital 250GB [Sata 1]
HDD3: Western Digital Caviar Black 640GB (WD6402AAEX) [Sata 3]
Optical 1: Samsung 223QRSMN DVD-RW [Sata ?]
OS: Windows 7 x64 Ultimate

As you can see my build can be considered high-end.

So far I have overclocked CPU to run at 3.0 GHZ and RAM speed at 1800 MHZ.
If I set CPU to run at a higher speed the system boots fine but the OS refuses to start

Also I have encountered some hang ups in games. I believe it's because of the automized RAM timings.

In order to overclock I have to access the "Cell Menu" in BIOS Settings.

The Cell Menu has exactly these options:
Current Core Frequency: 3.00 GHZ (150x20)
Current DRAM Frequency: 1800 MHZ
Current QPI Frequency: 4.8000 GT

-> Spread Spectrum: Disabled, Enabled

Text in blue means that these options are Disabled by me
Reasons: These technologies conserve power, I want to have better perfomance not to conserve energy.
Text in grey means that these options cannot be changed

Ouf, that all the options in Cell menu... This motherboard must have been designed for professional overclockers.
So any suggestions, any guides that I should follow?
I have heard and seen on the internet that Core i7 920 can reach 4,0 GHZ but not quite stable can I achieve such perfomance with good stability?
How do I get the real full specifications of these RAMs?
Should I enable some of the CPU features to conserve power and have a better temperature?
Should I enable also green power?

PS) Again to clarify it. I'm aiming for perfomance.

  1. A quick and easy way is to up the base clock to 160mhz. Then just adjust your multiplier down some to fit your desired over clock.. the stock multiplier on 160 base clock may be too much for your setup but just try it out and see.. Check temps and then make adjustments accordingly.

    Matching the base clock to 160 is the only way i could get my corsair memory to run stable on my gigabyte board. If i leave my stock multiplier of 21x on . it gives me 3.36ghz, which runs perfectly fine. Just turn turbo boost of if you are running on the hot side and dont want to push it any more.
  2. The bios reports that this CPU does not support 21x Multiplier.
    However I have already tried running at base clock speed 160 mhz.
    It does boot but Windows refuse to start and the system goes into a restarting loop.
    (sometimes I hate windows when I don't know why they are acting like this)
