CPU not using full overclock power

[Jewfishy]

So I've been overclocking my CPU today (i5 3570K) and got it to a stable clock of 4.2 Ghz. However, when I run stress tests it will not use more than 4000mhz, even though it says I have 4200mhz to use in the bios. As well as CPU-Z saying I have a max multiplier of 42. I have had no BSOD errors or crashes, it just won't use anymore power than 4000mhz. Any help would be greatly appreciated, thanks.

Do you have the Turbo Boost thing disabled?

since its not a K cpu,i think only with boost will go to 4200. and thats for a single core

 

thats why you only have 42x,you can overclock non K cpus just 4 bins above turbo.

It is a K, atleast that's what it said on the box

It is a K

no its not. hence your cpu-z SS and only 42x in bios. 3.8 turbo + 4 bins = 4.2  . or 4000mhz on all cores

To add one more thing, if it was unlocked in cpu-z it would have a k after 3570, as you can see there is not one. It should read 3570k, if it was that unlocked.
