I have the F3-17000CL9 2x4GB Kit (2133Mhz Modules) and at the bios and CPU-Z screens it shows me 2 available profiles for getting 2133Mhz and Id like to know which one is more optimal for Haswell.

Neither profile will make any diff in actual system performance.
You might want to try the first one (XMP-2134), which has a 2T command rate and check for stability under Memtest86+ V4.20 or later and also under P95. If your system is 100% stable for 2-24 hours (depending on your needs), then you can try the tighter settings which may also work. RAM frequencies are dependent on the RAM, mobo, CPU and BIOS settings combined. Not all CPUs or mobos will support the higher frequency RAM even if the RAM is capable of the advertised frequency.
Profile #2 should work great for Haswell platform and CPU.
