I7 920 DO at 3.5GHZ at only 1.15 stble is it safe

[Devam]

hey guys this is my first oc of my i7 920 with do stepping
i was able to get my cpu to run at 3.33GHZ with turbo on which gives me 3.5GHZ im happy with that i have ran prime 95 for several hours withought any errors as far so is it ok for my cpu to run at such low voltage


my system specs are

cpu i7 920 do @ 3.5GHZ at 1.15vcore
gpu sapphire radeon hd 5870
psu coolar master gx650
ram gskill nq 1600MHZ @ 9 9 9 24 2
mainboard gigabyte x58a ud 5 bios version f5
cpu cooler coolermaster hyper 212 plus (push pull)
case coolermaster 690 dominater (with 2 extra fans at the top)

so my question is that is my cpu and other parts of my pc safe

the settings i used were

bclk 166
and changed vcore to 1.15

rest is all srt to auto

so please help me and if any one has got a i7 920 do at 3.8GHZ pls post ur bios settings

srry for writing such a long post any help will be appereciated

srrry forgot to mention my cpu temops they are 40-39 at idle and 70-69 at full lode under 4-5hrs of prme

i live in India temps outside myhouse are 40c and in my room are about 22-24

pls post ur bios settings if u have a i7 920 do at 3.8GHZ stable 24/7 cause i want to reach there but i cant stay stable

here is my cpu z validation

Your temperatures are fine, and if you can achieve 3.5GHz stable with 1.15V vCore after several hours of Prime 95 then you're good to go.
