I know my chip can do more, its just that I am concerned about the insane amount of volts needed to break past 4Ghz.

HT is On

Don't use 21x multiplier. Use 19 instead. You can also try 20x multiplier.
I have a i7 920 and can get 4.2ghz using a 19x but not a 21x.
But wont I then have higher Ram speeds

Personally I would leave it @ 4Ghz w/ the low volts then waste the life on the CPU and run high volts just for a unneeded 200Mhz more.
I used to run my 920 @ 4.2 on my X58 EVGA... w/ 1.4volts... complete waste imo - even with water it would hit 80c
I agree, Kinda a waste since its ridiculous the amount of volts I require for only 200Mhz. But I am trying to get the most out of this chip without killing it. I am happy if it lasts me the next 2 - 3 Years. Its doing Under 85C

What cooling are you using? I've got the whole MB on water with 1.425 vcore but it stays under 75 to pass prim95 so I'm happy enough.
I am using a H70, Its doing Under 85C @ 1.425V @ 4.2Ghz.

EDIT: Also why is you QPI voltage so high?
I followed bits of this guide - http://www.overclock.net/intel-cpus/538439-guide-overclocking-core-i7-920-930-a.html
and it seems I need to increase the QPI to 1.4V+ to get it stable else I get BSOD.
Currently running 4.2Ghz @ 1.425V and QPI 1.425 VTT at 175mV @ under 85C Load on Prime 95 as I type. What voltages would you recommend me tuning it down to? Where should the QPI be set to? Under 1.4V? How far can I go? What do you guys consider safe Volts for the 4.2Ghz Overclock on a D0 / i7 930 Chip?
+ Reps. Thanks Guys.Edited by TheBirdman74 - 11/3/11 at 1:35pm
