Custom 3.07 GHz and DDR-1757
We already established that the Core i7 860 can easily do 3.06 GHz on page 4 of this article. Here we can acheive it with our own BIOS settings instead of a pre-configured profile (which I have never been of). The ECO RAM really gets its chance to shine here, putting almost any other stick to shame. It not only kept its low 1.350 voltage, but also kept a tight 7-8-7-24 timing with a 1T command rate at over 400 MHz over stock speed. By the way, if you have found any of your own sticks that perform really well, feel free to comment on it with the speed, timings, etcetera.
While everything went very well with this benchmark, I was not satisfied with the high temperatures produced during Prime95 testing. While 100% load on all cores is something that will probably never occur during regular use, I would rather keep a nice big buffer between my normal load temperatures and the Tj max. If you are unfamiliar with it, the ‘Tjunction max’ is a temperature ceiling on intel chips that causes the CPU to shutdown when reached. This happens to prevent damage to the chip. This maximum varies from chip to chip, which is why I prefer to stay as far from it as possible.

Thank you very much, I’ve found this very nice!
great post as usual!
Dude, this is a great article! Thanks for all the hard work. I couldn’t figure out why my temps were so high when I tried to overclock. After turning off hyperthreading it’s like night and day.
Just a question but why does the final screen grab say Intel Core i5?
That’s how Core Temp read the i7, as of version 0.99.5
photobucket has blocked the images, can you fix this or add a text based settings list?
thanks.
