I've been playing with an i7 860 and I'm finding it a pain to overclock. I can get 4ghz stable but it needs pretty high voltages at 1.392v according to CPU-Z. As a result, the temperature ends up higher than my i7 920 :/.
O yes it loves the Volts . 
Thats why i got this cooler. Stable i would say 4.125V @4.2 (thats 24/7 @Full load.)
ppl cry when they see my volts @ max Oc i have my QPi @1.46 and [email protected] at times. As i say its only bits of Silicon.
Yes they have a 3 year warranty but lets be honest you run a PC for 3 years its only fit for the bin.Most ppl only have the same Pc for for 18mths then upgrade if not they upgrade it a little,So why stress.

It is your CPU and I belive you can do whatever you like with it, but is the difference between 4.3ghz and 4.0ghz that big and worth the extra Volts? I'd say no, but everybody should answer this question themselfs
So I have one of these bad boys in transit, got a few questions though about turbo + overclock. I will of course be overclocking my chip but I will only take it to it's maximum stable overclock to discover what that is. Then I will take it down a bit for everyday use.
So I was wondering, given that these will do 3.8-4Ghz all day every day on decent air cooling; around about what would be the maximum OC to keep turbo enabled? Running at stock, with 3 cores idle, what's the Turbo OC on the active core?

Iam not the best person to explain this realy but will have a go
The best and most stable way is to just diable all the C1e and all that junk and just set the overclock as you would with anything. I have found 4Ghz to be a very good 24/7 clock nice temps and low volts.
If you leave the Turbo enabled you will get to 4.7 BUT its only on 1 thread. If you load them all up it will just drop to 3.5 (ish)
What cooler are you going to use ?

Either a Magahalems or a Scythe Mugen 2, I have both on order as I needed a new cooler + replacement. The mugen apparently performs really well with high pressure/airflow, and I have a couple of coolink SWiF2 120P's fans on the way.
What I'm really trying to figure out is if my day to day workflow is better with 3.8-4Ghz OC, or whether I should run a moderate OC at say 3.2-3.4 and leave Turbo enabled. One of the main reasons I went for this CPU rather than a 920 is the power consumption, the workstation it's going into will run 24/7 so the less power I can get away with using the better.

Because i only get £400 a year off my husband to upgrade
thats whyz.TBH You will not see any dif from stock to 3.8 on a day to day and prob only 30FPS max. I would leave it be till you want to BM.

You know what to do!
Get a new husdand

Ah yes these baby's do indeed love the volts. Here I am starting a burn with IBT maximum after passing lower levels of stress, I have a feeling this will *not* pass as I am not passing much juice for VPLL and VTT.
Note Vcore is actually 1.375 in BIOS but vdroop is in effect, enabling load line calibration with 4 ram sticks sends the temps up by at least 5 C, **** that.
I also seem to have a core that is at lease 3-5 C higher than the other cores at any time. After re-seating the cooling block and checking the spread of thermal paste I can only conclude that either it's a slightly lame core, the heat-spreader is not true or there is a dodgy thermistor.
