Memory not hitting 1600mhz (but already set in BIOS)

Post is longish, sorry for that, trying to make sure I include everything I can. And thanks in advance.

Memory: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226203


Problem:

I have an ASRock Fatality Professional Gen3 (2011 board) and an i5 2500k. Way back when I already went through all the trouble of fixing the ram so it ran at 1600Mhz, recently though, I rechecked it and it seems it's still running at 667 (dual channel so 1334) instead of 1600Mhz. I have my BIOS set to profile 1, which has my timing set correctly as well as my memory speed.

Redouts:

Max Bandwidth PC3-10700 (667 Mhz)

Various JEDEC 2, 3, 4 followed by XMP-1600 (running at 800Mhz). JEDEC 2, 3, 4 are running at 1.5v (incorrectly for this memory) and XMP-1600 correctly at 1.65v.


I don't know if maybe I'm reading CPU-z incorrectly?
