It doesn't seem we have a thread for the s1156 i7s, so as i have some results to share, i'm making this thread for all to add to :)
i5 OCing thread
_________________________________________________

After much fighting, it's obvious i cannot do 4 GHz LinX stable as i'd need more vcore than my temps allow for.

Kinda disappointing, as i could do 4.15 GHz LinX stable w/ my i5 750, but i suppose HT is nice to have...

For the i5 750, i could do ~ 200 BCLK @ 1.23vtt.
For the i7 860, it needs at least 1.29vtt for the same, or BSODs during LinX...

Here is as far as i can get with vcore/vtt as low as possible:
20x197%20(3940%20MHz)%201.3375v%201.29vtt%20DDR3-1970%209-9-8-24-1N%20LinX%2025%20passes%207%20P95%20custom%206GB%2012%20hrs.JPG

I thought in general, HT off overclocks bit better than HT on?
I've seen more people hit 4.2GHz+ on 750s than with 860s (HT on with the 860s)

Oh absolutely, but i didn't get an i7 860 to run it w/ HT off.
That entirely defeats the purpose...
