We need more system info.

Make and model of your memory and PSU.

Method used to OC (Bios or Software) and the settings you are currently using.

What are your temps.

What is the max staple OC that you've achieved so far.

If memory serves me correctly the early Durons weren't great OCer but we'll see what can do to help.

That is what everest ultimate edition says

and i used bios method to OC
settings are 113MHz FSB multiplier is 10X,voltage core is set to +0.325V
max stable OC is 1130MHz

Download and run CPU-Z and post screen shots of the "Memory" and "SPD" tabs.

First off loosen your RAM timings a bit. You're currently at 2-3-3-6. Take it up to 3-3-3-6 which is what your RAM is rated for at @ 133mhz.

Have you unlocked your processor? If not then do a google search for the pencil trick. Basically you reconnect the the L1 Bridge using a pencil, but I can't remember if you connect all bridges or not.

Also you're pushing the Vcore pretty hard. Your stock Vcore is 1.75v and you're trying 2.1v. That's 20% increase in Vcore and the path to a very short life for your CPU. The max safe increase is 10-15% (+.175-+.262)

ok,thanks for help
i will try to unlock but i don't know will my MB recognize higher multiplier because i can't change multiplier like on other motherboards.

Then DO NOT Unlock the processor. It will default to a lower multiplier defeating the purpose of unlocking.

Do you have the most recent BIOS Rev?

mattlock

Double check under "Advanced Bios Setting" for "CPU Frequency Multiplier". I can't find the manual for your board but others have mentioned having the option in BIOS. Although it may be on newer revisions.
