Having a P6T Deluxe giving a nice overclocking ability from bios and as far as I know i7 is nice candidate to do so. I am looking in setting in bios and I see nothing not a single parameter I know answer to so if possible can you please tell me each parameter what number I should set it to? I want to set a STABLE system with maximum speed. I have nice aftermarket cooler from ZALMAN the only one thing I think I am missing on is my ram I got myself GSKILL 1333 RAM here is my system info below. As far as I know I need to use BIOS + ASUS TurboV Software to fine tune. So if possible please let me know what should I do to make my system run at stable speeds. I found many setups but all of them have 1600 or 1800 ram so I am sure numbers from settings with 1800 RAM will crash my 1333 system. Thank you very much.

My setup is very close to yours. I am using the core i7 920 on Asus Rampage 2 Extreme. I am using Corsair Dominators rated at 1600mhz.
My settings have my system stable at 4.0ghz with the ram running at 1600mhz. Your ram probably defaults to 1066 or 1333mhz on that board, correct? With these settings they should overclock to 1600mhz which your ram should be able to handle. 1800mhz I agree would be too much. The key is just increasing the voltage to a higher but safer limit to reach stability. Here are my settings:
BCLK Freq: 200
DRAM Freq: DDR3-1603Mhz
CPU Differential Amplitude: 800mV
CPU Voltage: 1.43125
CPU PLL Volt: 1.94842
QPI/DRAM Core Volt: 1.375
DRAM Bus Volt: 1.65681
and I set my DRAM Timings to 8/8/8/24, which I'm running Corsair DDR3 Dominators that are specced at 1600Mhz.
Fyi I am watercooling also, but I've seen people do these on good air cooler. If you can't get system stability, just drop the BCLK frequency until you reach something that is stable.
I wouldn't say that those settings would guarantee stability - it's hard to say for sure. Every CPU is different. Also, that PLL voltage looks a bit high - I'll have to check what mine is set at, but I'm pretty sure that it's quite a bit lower than that.
As for tweaking, if you set it to manual, bump the bclk up to 170 or so, up the CPU volts to get it stable, and set the RAM to DDR3-1360 (should be an option at BCLK 170). That should give you 3.4 GHz without any trouble - I'd expect it to work at no more than 1.3-1.35V (and probably quite a bit less). From there, you can slowly inch it up, possibly as high as a bclk of 200 or so for 4GHz. The process isn't that far off of the old FSB overclocking.
Oh, and just for reference, here are Intel's voltage specs (max):
Guys I am sorry I tried few things from here and it does not work always crash. In my bios there is no such thing like Vcore or Vdimm ....if someone know specifically P6T Deluxe bios can u please post numbers or may be translate this vcore , vdimm and other to represent my setup ?
PS I am trying to archive speeds of 3.6 3.8 Ghz no more than that. If you need me to print here all things I have in bios under overclock settings tab I can do it I just don't think 40 (that's about lines in there) different things is needed to overclock to somewhat medium clock speeds.
Again I am sorry and thank you very much trust me guys I am trued to do with things you told me before ... may be some explanation.
