:hello:  So i havent been around for a long time you know gaming all that fun stuff, I came here a while ago trying to push my i7 920 to 4Ghz and only ever could get it to 3.8Ghz never work out why! i thought hey ive got a Zalman cpu cooler with great heatsink why isn't it getting there..
Anyway to cut a long story short a few weeks ago i decided to put my SLI'd 9800Gt's away and upgrade to a nvidia Gtx 470 and that made and excellent diffrence in fps. then decided to get my all time favourite Ram modules, the Corsair Dominator GT 2000Mhz kits, so i went and bought x2 4GB kits total cost $506 AU . Installed and thought i'm going to start overclocking this cpu again hence the better ram. So i found my Stock vid volts pushed my bclk as far as i could which was 3.8Ghz until i had to start increasing the Vcore from (vid) 1.6 - 1.28, VTT 1.28,VDimm 166, so my i7 920 is now overclocked to a stable AMAZING 4.2Ghz i mean stock 2.66Ghz is an AMAZING leep in performance i am now gaining 900 Fps in game whilst before with my old ram,SLi 9800Gt's, a 3.8Ghz cpu was only reading 200-300 Fps in game. This is an outrouges perfomance jump the $500 spent on this high end ram was well worth every penny.

Thanks to tomshardware.com for the interest in overcloking to begin with

p.s: i have recorded my cpu-z/ realtemp and will upload it to youtube and edit this so everyone can see you do not need a watercooled system to achieve 4Ghz + i7 920

Umm... 900fps? 200-300fps even? You realize that the human eye can only see about 28fps right? :p

And a monitor can only display 60 (120 on some more modern ones or CRTs).

I want to see a video (or even a screen shot) of that 4.2 Ghz OC (even w/HT disabled like it was) running prime95 w/coretemp or realtemp open for 10 minutes.

How on earth did u get a 4.2Ghz OC running @1.25v??? Thats impossible!! At least I cant do it.. I have i7 930... What are your other BIOS settings, please?

lol, that whats i think too. im not with intel i series, im on q9450 default 2.66Ghz and i OC to 3.51Ghz and about 1.32V

yeah like its been said your typical monitor cannot show any higher FPS than it's refresh rate. So 900 FPS is rubbish.

Human eyes doesn't refresh like monitors so we can technically see unlimited refresh rates but we can't percieve small movements. So if a slow object hardly moves between each frame at lets say 28FPS, you eyes won't notice any difference from 280FPS but with fast objects you can easily notice 120FPS easily.

28FPS is actally very very slow. 40FPS is where games become playable. 60FPS is considered smooth. If you seen 120Hz monitors, I think they can still be even smoother.

Im running 4.0Ghz @ 1.26v to survive P95. I can boot windows as low as 1.15V! But that doesn't mean anything. You should really test your computer first.

CPU-Z would always report core voltage to be lower than BIOS settings becuase some voltage is allocated elsewhere.
