2600K and DDR3 1600 reading 1333?

Next to 'max bandwidth' it says 667Mhz.
Op - what does it say in the BIOS? Does it show as 1600Mhz when you set the XMP? Have you tried to use another program, other than CPU-Z, to see if that's the issue and not the RAM?

EDIT: My bad - just seen the last screen shot with MSI control centre. And CPU-Z does read it as 800Mhz under the memory tab, just not the SPD tab. . . strange!

I've seen this sort of confusing data feedback in software before and usually it's the result of it reading the SPD (specifications data, which can sometimes not be all that accurate) for one result and the other showing what the RAM is physically running at (as in the timings section of the screenshot).

This is why I always configure my RAM manually, I've always found SPD auto configuration to be somewhat unreliable (though necessary as not everyone is familiar enough with it to manually configure). Looks like you manually set your configuration for 800 (1600 effective) and you are good to go.

I've got an Asus P8P67 Deluxe with i7 2600k and my RAM is 1600MHz but as default it is set to 1333MHz so to put it up to 1600MHz look for XMP in the BIOS (Extreme Memory Profile)
