I got my Vortex IV July 2014 and ordered the 2.9GHz i7-4910QM. Looking in CPU-Z, the CPU identifies itself as exactly that. But the clocks core speed identifies as 3790.95MHz and shows a multiplier of 38 against a bus speed of 99.86MHz. That sure looks overclocked to me. I've looked in the BIOS and didn't see anything in there where I could get a multiplier, so I imagine it's a jumper on the mobo.
Firstly, am I right? And secondly, with such a big amount of overclocking, I'd guess this is the reason for my excessive cooling fan noise and the CPU so easily heating up and getting towards 100 degrees C. Thirdly, if all that's true, how can I get it back to its normal non-overclocked speed? I'd rather a CPU running at the speed it was designed for and not getting too hot than one living fast and heading for an early grave.
I've got screenshots from all the other CPU-Z tabs if any others are more relevant.

I'm currently running at max CPU of 50% and I can't notice the difference. If I'm doing some heavy stuff I might use the profile that has CPU at 100% max to get the turbo boost, but for every day emailing, surfing and playing a bit of candy crush, I just don't need it.
