I tried enabling the XMP profile in my BIOS which says it would run at 1600, however the computer wont boot. I need to restart the computer in order to boot again. Luckily my motherboard lets me get into BIOS after failed post and switch settings.

Also, I put DRAM Voltage to 1.55V because I found this advice on multiple forums, but still, no luck.

I found this on my MB manual:
"ddr 1600 mhz and higher memory frequency is suported by intel 3rd generation processors"

Could be this be a problem? I need a newer CPU than my i5 2400 in order to activate XMP?

Any help on getting this to work?

Bios up to date?

The 2400 is nativley supporting 1333MHz, 1600MHz can work but eventually with higher timings like Cl10

Yes, i have the latest version of BIOS.

Anyways, the 2400 will not improve in performance with 1600MHz, just let it run with 1333MHz.
