Is this a decent overclock?

Just built a new system with a 4770k, and this is my first real stab at overclocking. I didn't want to go too overboard, so I shot for 4.4GHz for now. I ran Prime 95 for about 10 minutes and here's my results:

Here's my new rig, still waiting on the video card (ASUS GTX780 DCU2), so I have my old HD5870 in there for now.

You should use Intel Burn Test if you're doing short tests. Prime needs to run for hours to get an accurate result.

prime should run for at least 12 hours for semi-accurate stability indication.
As for Intel burn test, 10 passes is good.

How's that? Seems a little high, mind you my ambient temperature is around 25C or so.

^This, although I would go for a few more passes of IBT.

To answer the question though, 4.4GHz is a great overclock for a 4770K.

Edit: Just looked at your second screenshot. You want to run IBT at the maximum stress level.

Seemed fairly stable. How are these temps?

Not sure where people got the idea that Intel CPUs are rated for 100c. 4770k is only rated for ~72c.

Want that Shield!

Are you sure? I think I would hit that at stock speeds, nevermind with the stock cooler. A cooler review said that 100C was their cutoff margin, mind you, I think they did 4.5 or 4.6GHz with a lower ambient temperature.

TCase is 72.72C. TJMax is 100C.
