"K" unlocked CPUs in an H77 motherboard

I can't seem to get a straight answer to this question, so I thought I'd ask on the intel forums to put it to bed once and for all.

 

 

On the H77 chipset specification, it says "Supports the 3rd generation Intel® Core™ processors with Turbo Boost Technology 2.0 Intel® Pentium® processor, and Intel® Celeron® processor. Intel H77 Express Chipset also enables overclocking features of unlocked 3rd generation Intel® Core™ processors".

So... two questions to confirm I have understood this correctly:

 

1. Suppose I own an I5-3570K and a H77 motherboard. In theory I can overclock the my 3570K to 4.5GHz (for example...) by entering the BIOS and changing the multiplier from the factory value of 34 to 45 (for example).
Correct, yes or no?

2. Suppose I own an i5-2500K and a H77 motherboard. I cannot overclock this CPU to 4.5GHz as described above, but can still increase its clock speed to its max turbo frequency of 3.7GHz.
Correct, yes or no?

Thanks in advance!
