It is stable at 182, but anything above that and its not

I wouldn't have pushed it to 4ghz if it wasn't rock solid

That depends, kona, on cooling, how far it's pushed.  The biggest, most common mistake is pushing the overclock way too far: and the second; not providing adequate 'third party' cooling, given the chip will run that bit hotter... and it is the additional heat that'll kill an overclocked CPU faster than anything.

I had read that others had overclocked their AMD Phenom II 920's from 2.8ghz to 4.0ghz - 4.3ghz, but I just clocked mine to 3.4ghz and stopped, and with a Zalman cooler it is running very cool and stable between 40c to 45c.  In fact, the CPU is running quite a bit cooler than it was with the stock cooler at standard settings, so I'm not overly concerned about shortening its life.

Having said that, Cap'n A (from one captain to another ) I don't know that I'd be content with that 4.0ghz overclock if it weren't 100% stable.... I'd have to wind it back until it was.

Yeah, that's why I invested in a new Thermaltake case situating the PSU on the bottom, thus blowing its hot air outside the case rather than inside.  Not only that, it has a 12cm rear exhaust fan, a 12cm front intake fan, and a 23cm top exhaust fan, so the case interior is well ventilated and kept reasonably cool.  I do have the option to add a side mobo fan, but I don't thinks it's necessary at this time.... though I'll  see how it goes during next Summer.

Oh, OK!  That is not necessary in my instance, then, I'm stable at 3.4ghz and intend to go no higher.

Wasting money 'when' he fries his chips....

Here are a couple of more sites for help

I run my 920 at 3.93 have since i got it last year 19*207 with Memory at about 1660 Mhz  and stock memory timings of 6 7 6 18 redline Mushkin sticks.

I have had it up to 4.0 on air cooling to go above that you should think about Water cooling the 920 on water can run stable at about 4.4 or 4.5

Just remember the following if you increase Dram voltage above 1.65

The reason being is that Intel requires you to keep the DRAM Bus voltage and the QPI/Uncore voltage with a difference no greater than .5 volts as it can damage the hardware.

@Kona: I am not new to overclocking at all, I know the risks and I choose to take them. If the chip lasts 3 years instead of 6 it won't much matter because in 3 years it will be time for a new rig.

@Starkers: The 4ghz OC is completely stable, memory, proc, everything. But at a bclk of 183 (instead of 182) the system bluescreens after maybe 3 min of Prime95.

I have an Antec 1200 case and a Cogage True Spirit Cooler, the CPU cores don't go much above 70C even with hours of prime95. The NB maxes at about 65c.

The temps don't seem like the problem.

It is either the Board maxing out, or a voltage I need to tweak, anyone have any ideas?

Ahot Cap'n! I have a batch number 3951A689 i7 930 and I can not for the life of me get this thing stable at 183 or higher. 182 is A+ at 1.3v, but all the volts and tweaking I've tried haven't given me anything stable from 183-220. I'd love to hear what batch you have and what you have tried to get some stability out of it.

Overclocking on such a small scale may be OK. My point is mainly that the i7 wasn't designed to be running at 4.3 GHz.

Your both off base. The chips have designed voltage ranges, bclks, and thermal loads. Staying in those won't affect the life of the chip. i7's have a voltage range of .85-1.35, a bclk range of 50(I think) and 400, and a thermal load of 85c staying in those specs has no effect outside what the retail specs would have. About the only thing you can do that would have a negative long term affect would be overvolting underwater to maintain stability at the high end of those specs.

Which limits? (Aside from the voltage; which I mentioned is dangerous to your hardware.)

Edit: Typed on a PhenomIIx4 965 running 4.2GHz 1.4875v at 31C stable since March while looking at the screen of a i7 930 running folding at home on 8 threads at 3.85GHz 1.30v 69c running 100 percent load since Saturday night

I didn't mean to come off like a jerk, you just didn't seem to have the proper perspective and I was trying to add some. Overclocking within spec is perfectly safe. Retail clocks are the lowest clocks that every CPU in a batch has been binned at and will run stable at in all circumstances. Aftermarket cooler or decent AM case = changed circumstances, better clock speeds open to you. Additionally with the i7 920s and 930s they sell so effectively that chips binned as 975X are sold as i7 920 (i.e. week 45-49 2009). The stock clock speeds are just the absolute bare minimum. Why not get your money's worth if you know what you are doing?

Looking forward to the Cap'n showing up so we can find out batch number, since, I believe, I've ruled out his mobo as the stability issue as I have a MSI X58 Pro-E (stop laughing) with the same sticking point.
