That could be for a multitude of reasons. I don't know what settings you are using, what you've changed in the bios, so I can't tell you if that's bad or good.
However, I'm pretty experienced with moderate OC's. So the main thing is to monitor temps on your CPU. Use HWMon. Make sure your CPU temps don't go above about 80c. If your temps do go above that, then your OP too high.
There are too many things to explain in a thread like this. Please read the guides. There is no point in OC'ing if you don't read and learn about first. You will just get frustrated and not get the results you want. 1.368 is possible depending on what other settings you are using. As you increase the speed of the processor you need more voltage to power it so it's stable.
If I can give any advise, if this is your first time OC'ing, it would be to read, read and read some more before trying it. The idea is to get max speed, min voltage and temps below 80c. If you use those 3 parameters as basics, you may have some success.
