This is in Spanish, but numbers are the same as in English:

Googling, it seems that there are both Intel and AMD 920 processors, so I don't know which he has.

Oh boy, I assumed it was an Intel, I guess we won't know til he replies.

I thought it was this - http://ark.intel.com/products/37147

Edit again, will the 920 AMD reach 4.6ghz? I didn't thing AMD were so overclockable? I stand to be corrected as I have absolutely no knowledge of AMD cpu's

66c on Prime95 and 68c on IBT are the limits for me on an Intel I5-760. Expect the 920 should be about the same. 75c is kinda high for an Intel and I think way too high for an AMD.

And if this is an Intel 920, overclocking it by 2 GHz is waaay too much IMO. If you are just doing this occasionally, well OK, but if it is 24x7 I wouldn't go over 1 GHz, personally.

AMD or Intel and what are you using to generate the load?

One thing that concerns me is the temperature of the cores under load.
Idle = 45 C on all 4.
Load = 75 C on all 4.

Steady, no changes. BTW, never a crash (program, windows), weirdness, or any anomalies.

Thoughts?
Do Not Overclock!

If you want a faster processor, get one.

Overclocking is just asking for problems.

If you want to fight all odds, then at least get yourself a monster-sized cooler for the processor to get the temps down some.

The only thing that is saving you right now is that modern processor will throttle themselves to keep the temps from getting astronomical.
Have to disagree. As long as you know what your are doing, don't overdo it, and have the right equipment (cooling and motherboard most important), overclocking is fairly easy and risk free. However you need to do your research first.

AMD 2.8 GHz
Intel 2.66 GHz

He said he overclocked from 2.67... he more than likely has the Intel processor.

75C is a tad high, but for that much of an OC that is pretty good temperatures. What voltage is it running at (that will make a big difference as well)? I am assuming this is an i7-920K CPU.

I would also make sure you have adequate cooling for that much of an OC.
I forget what the stock voltage of that CPU is, but you don't want to bump it up past about .2 volts over the stock setting as that could blow the CPU. I would guess that you are way high on voltage.

When you stress test, all you need to do is run Prime95 for over 24hours. No need to do ALL the stress tests, Prime95 for a full day will pretty much guarantee stability.

More like 'Do Not Overclock unprepared'. Or at least like the OP, ask questions along the way.

Overclocking can shorten the lifetime of a processor through the process of electromigration which destroys traces and other features on a chip. Temperature has more of an affect on electromigration than voltage (it depends exponentially on temperature and only quadratically on voltage).

http://en.wikipedia.org/wiki/Electromigration

This is because the temperature loosens the ions in the lattice so that they can be more easily dislodged by the electron current.

You also have to monitor the stability over time. In just over about a year I have had to bump up my VCore a click to remain stable. And that is with a 1 GHz overclock at 65-66c on custom (heavy duty) Prime95 load.

Couldn't disagree more. Back when I built my machine, I got the Q9550 for like $209. It's stock clock is 2.83Ghz. If I wanted to spend $329, I could have gotten the Q9650 which is same chip just running at 3.06Ghz. So, I bought the Q9550 for $209 and then upped it to 3.2Ghz for the first year and a half and 3.4Ghz for the past 6 months and it's been stable as can be. So, I saved over $100 and am running faster with complete stability and no need for extreme cooling.
