1.72V's on the RAM risky guy
I will be keeping an eye on how your doing for sure
People doing extreme overclocks is at risk, the more moderate overclocker is not.
I use 1333mhz ram, and since multipler is from 6x I can do 4ghz if the chip/card and such allow it without exposing a lot of volt to vdim and not qpi.
Intels rec is similiar to micro ovens, since some metals is possible to use inside the oven, however, knowing people they wouldnt know the difference between safe or not so much easier to just say, do NOT extend over 1.65v
I use cheap *** ram, rated for 1.5v, and when my waterblock comes, I much likely are aiming for my 4ghz goal.
And as far that goes, it seems for me no special risk involved doing so.
One thing I will certainly miss is running 2.2v through my DDR3.
Quick 30 second update....
Got my new memory and all is well
3.9GHz (178bCLKx22) is as far as the system will go without any effort put into it.
Bumped the Vcore up a notch from 2.0 to 2.23V.
Uncore is running at 2850 Mhz
Have the RAM at 712Mhz
Sadly work has me going away tonight and i have to wait till Sunday night before I get back. Hopefully i can find that new BIOS i hear is floating around. F3 sucks and F4C i hear is much better.

Did I read this correctly my friend? If you bumped the vcore up to 2.23v, you are surely going to fry that chip in a few hours on air cooling. Maximum recommended vcore should be no higher than 1.40 to 1.45v on air cooling using i7. Be careful my brother. I am assuming this is a simple typo.

I have new numbers now....Since bCLK is 178, I can calculate the multis
2850/178 = 16x Uncore MAX
712/178 = 4x? Shouldnt this be 8x?
From the information you present, looks to me that max memory multiplier on stock Core i7 920/940 is 8x and then only supports 1066 MHz memory.
Are you able to bump the memory higher without changing bCLK?
