XMP profiles won't boot

[newbie1337]

Hey community

I recently bought a new pc with the following specs;

Asrock extreme 4 mobo
8gb Kingston hyperx Beast ram @ 2400mhz
Intel i7 3770k
corsair force 3 240 sdd
Seagate barrcuda 1tb @ 7200rpm

And my ram runs @ 1333mhz when i try to enable xmp profiles my system fail boots 3 times and then resets the bios. I haven't updated to bios but I'm not sure that is the problem as i bought a simlar system for a friend 3 months ago with the same specs expect had an i5 3570k and it ran fine. any suggestions?

Read the review and may help, the point is that you need tweak the voltage, because you do the OC the RAM and you can't just enable the XMP.

I set the ram voltage to the recommended 1.65v and it still wouldn't boot sucesfully. I tried running xmp profile 2 (2133mhz) and that one ran without a problem :S

I have the same problem with Asrock Z77 Pro4. It's another ram that has to run on 2400mhz but the max is 2133. I hear 3 beeps the pc restarts 3 times and nothing, it's like something prevents the motherboard to even try to load.
