AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[Akrian]

I need your help guys. I've got a x6 1090t.
Aaand so far I've tested it with OCCT at large data sets test. After a bit of hussle I've got 4h + stable at 1.425 volts ( in bios) at 4.0ghz. In cpu-z it shows that at idle the volts are at 1.44, during load it's 1.456 -> 1.467. Question : ARE THOSE VOLTS SAFE fro Thuban 24/7 use ?
I've seen the AMD states 1.4v to be the max.
P.S. I very much do like those 4.0 ghz =)
my temps during load are : 55-56.

P.S. Maybe some day I'll do Linpack, but in my experience the occt was the best one. On pc's that I could pass 12h of Prime, and take IBT for 1-2 hours to make a nice fried egg I've faild OCCT in 1-3 hours.
