Guys, recently i put my 920 to run at 3.2 (154x21)... the thing is that i'm with a vcore at 1.056v and stable, when the stock is 1.24v :ouch: 

I know it's a small oc, but i'm using a intel cooler, so...

I'm stable, and i know that be stable at a low voltage is good but this vcore scares me... it seems too low...

Can i damage my CPU running at such a low vcore, or its okay beeing stable? Also... What stability test u guys recommend me to use? i'm running Prime95 now.

thanks... and sorry for my english, i'm brazilian :D 

Here are my specs:

MB Asus P6T
Core i7 920 D0 @3.2, 1.056v
Ram 6GB DDR3 1600 (Patriot), Running at 1224Mhz at this momment.

That indeed is a very low vcore, just consider yourself happy, and you should be ok with the intel cooler as long as you monitor the temps and don't push it harder than temps allow.
Running the 920 at 4 GHz at 1.27 vcore is not that uncommon, they overclock easily and many don't seem to need that much extra voltage.

Yes, use Prime95 and run it using 8 workers, and monitor your temps, preferably keep them under 70­° celcius.

Thanks, How much time do i need to run prime95 to confirm my stability?
And also,even beeing stable, can my cpu be damaged running at this vcore?

Once you have found the overclock you want to run, let it test overnight, 12+ hours preferably.

Undervolting should not cause any harm to your CPU.

Please read Overshocked's 920 overclocking guide.

Another great guide is found on Asus' forum.
