@Natima, yeah C0's require a lot more Vcore for 4GHz than the D0's..

About my current chip, I have been chatting with the tech guy @ OcUK about this processor and how I'm not at all happy about being given this as a replacement for a fairly decent chip that I had returned, and he has agreed to change this one over again for a chip that he will guarantee will run @ 4GHz with low voltages!!

He has told me to give him a few days so he can cherry pick a decent sample for me, so I am extremely delighted about this..

He told me that this would be the last time that he can swap this chip over, but if I am getting a processor that is guaranteed to do 4GHz on low voltages, then I will have no need to ask him to swap it over again!!

I wanted to ask you guys about the temps I am experiencing with this current chip.. is it possible for some chips to run hotter than others?

With my last chip, I had it running @ 4GHz with 1.264v Vcore, and .1355v QPI, and idle temps were 44c and full load they would hit 82 to 84c, but my new chip running @ 3.8GHz with 1.248v Vcore, and 1.300v QPI and it idles @ 51c, and hits 88c under load...

I don't understand why it is running so hot when it has less voltage going through it, it's running @ a lower frequency, and I am now using a TRUE instead of my old Zalman 9700NT...

I have tested the Zalman on this new chip as well just to see if it would keep it as cool as it managed to keep my last chip, but the temps went up to the low 90's!!!
