Overclock check?

I went to my bios and they had an option for OC auto. I chose 4.4 ghz for my i5 2500k. I am trying to check it in cpuz but it keeps throttling down. How do I stop that? Disable speed step? And is it ok to do that?

You should be running some CPU intensive programs to see the frequency reach your selected values. You could try Prime95, Orthos, IntelBurnTest, LinX. Unless there is some good reason, no need to disable SpeedStep (though, if needed, you can do that in the BIOS).

Ok this is what it says
4389.85mhz
multiplier 44
bus 100
voltage is looking like it stable around 1.39

cpu temp is right now at 70C and climbing. What is a safe temp for it?

Ok changed it up.
Changed to a manual Overclock.
Only changed multiplier to 43
Now have 4300mhz
cpu temp 59 at full load.
voltage 1.277

70C+ looks a little high if the case has sufficient ventilation, and the room is not warm. When I had the same problem, the gerbils suggested a better thermal paste and possibly adding a better CPU cooler.

Looks better now. It is recommended to run one of those tools for more than a couple of hours to ensure stability. Also, not sure what you are using to monitor temperatures - RealTemp and CoreTemp are usually suggested.

I'd recommend Prime95 as it will not only stress the CPU but test ram and other things in the process and let you know if your returning errors with your overclock, also logs information along the way. Just let it rip and call it good. I personally don't like to let anything of mine get past the 60-65 barrier at full load. If your hitting 70 at 4.4 vs 59 at 4.3, then I'd sacrifice the 100mhz in order to lower your temps by 11*C, that or get an aftermarket cooler if you feel the need to push it a little further. What PSU/Motherboard are you running with that?

If your going to get into the aftermarket cooler I was told the coolermaster 212+ is good.

If you do that your also going to want to use something like Arctic Silver 5 (an old standard) or some of the new overpriced stuff with crushed diamonds in it. I've been a big fan of AS5 since back in the early 2000's with my AMD Athlon system, worked wonder even with the stock CPU. But for the most part your going to see little results when it comes to using an aftermarket thermal paste with a stock aluminum cooler.

If you want to buy some other hardcore cooling products you can look here too. FrozenCPU.com. I haven't purchased much from there in a long time, but what I always loved on that site was their ability to carry coolers than no one else had. They also carry a high number of pure/solid copper heat sinks. If you have the choice of copper vs aluminum (assuming all other things like design are equal) ALSO go with the copper as it will move so much more heat.

That is with the ASRock Z68 Extreme3 Gen3
And I already have a h212+ Cpu fan. I didn't realize how big that heatsink is till it came in. Holy god.
The computer runs great at its current overclock. I have ran prime, also have played arkham city for hoursssss without a crash.

Good call on manually setting the OC. Always keep voltage at stock if at all possible. This will ensure lower temps and longer life expectancy of the CPU. The only time I suggest increasing voltage is for a temporary overclock as it does help maintain stability at higher clock speeds. 59C under load at 4.3Ghz is perfectly fine, temps depend on how much cool/fresh air your cpu fan is getting (aka case ventillation) as well as thermal paste quality and distribution, HSF mounting pressure, heatsink performance, fan speed, etc. etc.
