Can I boost my i5-3570k on H61 motherboard?
Yes, you can overclock your i5 3570k.
Nope, the Z68 or Z77 board is required.
You really just require a unlocked board from the z or x series.
The i5 3570k is not suitable for any X series boards.
You were misunderstood, I didn't intend to refer solely to this socket. Generally, Intel permits overclocking only on z and x series motherboards.
