im using bios 16... im starting to believe that i have a defective chip. i once bumped voltage close to 1.55 when i was on stock cooling trying to get prime stable, but that was for 10minutes max and uguru never showed more than 75-80 C. would that cause degradation or sth on the chip that could justify this kind of behavior?

thnx a lot for the answers


edit : this pic is from 12mins of priming @ 400fsb all stock except vcore which was 1.2850 (it would get errors after the 1st test if i set vcore lower than that). isnt this kind of vcore needed too much? and are these temps showing that im in need of doing the bolt mod on my m/b?
I see that you use a 2 x 2gb kit of ddr2 PC6400 , do you know their potential ? may be they are the weaker point of your OC ? Did you test their max OC ?

With 2 x 2gb kit you will have to increase the Vmch a little bit more than with a 2 x 1gb. I was on the bios 17 final when I tried the E8500, don't know if it's change something ?
