If I remember correctly, mine was around 3.5-3.6Ghz range (can't really recall though).

mine 3.825ghz on all stock setting

using dfi dk p35..erm im not sure bout ur mobo..but as flat said  tru oso 

i have a p35-ds3 rev2.1 , there should not be a problem going beyond 3.6.  i  manage to hit 3.7 with stock heaksink, but my temp is too high. Set ur voltage to auto. The mobo will auto adjust the voltage for u.  From there u will know how high u can go. After that only slowyly reduce the voltage.

Not sure about the others, maybe u can try this method first?

You mean stock vcore?Depend on luck lah.Some can go 3.8,some can go 3.3.

have not tried 4ghz yet cause of temperature issue, i am using e8400 too. The only thing u can do is increase ur vcore.  leave ur mch and fsb to normal. the board can adjsut itself.

actually it's the combination of hardware and user skill.

screenies??

lowest voltage on my mobo.
[attachmentid=414731]

hmm can do up to 3.375ghz but will fail in 1 hour 9 minutes..

its multiplier 8 lor its 400x8..he's not using 400x9..

do u guys disable C1E and EIST during OCing?... cuz i don't maybe thats why its not stable at lower vcore...
