Core i7 Overclocking thread

FYI, my D0 might run a bit warmer than my C stepping chip, although it certainly has more OC headroom.

my 1st C0 chip failed after a month on an OC at 3.20ghz, too scared to try it on the replacement C0/C1 chip

i had used the gigabyte utility

I have heard horrible things about the gigabyte utility.

Maybe I'll order one in a week or two.

This is true, my C0 was out of this world.

Well just thought I would post my fist oc on my I7 have not messed with voltage at all yet just upped the speed

Overclocked



and at idle



I have noticed that one core is running 4 or 5 degrees lower than the others, not sure why I may have to remove the HS and redo the paste again. Tehn try upping a bit more

That temp delta between cores is normal.

Yikes it got up to about 70C in about 10 minutes of Prime 95?

That's normal for an I7

What is the max temp after about an hour of Prime 95 running? My Q9550 after an hour of Prime 95 hits a high of 60C in comparison.

I will have to try it out at stock settings, if that's what you mean. As soon as i bought my first Chip they have been overclocked right out of the box. 4.2 hit's the 80's with 1.3 volts for me. Will post back with stock settings later.

Oh no I didn't mean stock speeds, I was just curious about what they hit while overclocked after an hour of Prime 95. I know it will vary with speed. I should have also said the 60C I said mine hit is with it overclocked to 3.8 @ 1.256 volts. I guess the I7s run quite a bit warmer than the quad duos.

The I7 is quite a bit larger than the Core2 design. I can try a comparison and run mine at 3.8 with 1.25 volts if you want.
