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

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.
