I have a intel i5 3570 (3.4 ghz- 3.8 ghz at turbo) non-k processor, and I have read many articles on google, that it can be overclocked to 4.2 ghz. But the problem is here, when I enter my bios setup, I can only set the multiplier to 38, and when I restart my comp. I open Cpu-Z which says 3.8 ghz. I really want to push my processor..
