Hi guys i build a new PC and i'm having a problem .When i start up the PC it makes short beeps(0.8-1 secs) and i have no display (tested different monitors, cables and ports) according to this http://www.computerhope.com/beep.htm (i have AMI BIOS) it's a ram failure. I have only one stick and no other to troubleshoot this so i tried to remove and then change the RAM slot, both cases still had those three long beeps. Does that mean that it's a faulty module/stick? The MB is new so i guess that it's nearly impossible to be both slots faulty, right? One more thing : when i remove the cpu power cord(4-pin) the fans only run for half a second and then it shuts down whereas my other PC's don't do this.
Specs :
MotherBoard : AsRock H81M-DGS R2.0
CPU : Intel core i5 4690K
Ram : DDR3 8GB 1333 MHz
PSU : Unknown 400W tested on other PC and it's working smooth & without problems

Ok, without looking up exactly what that pin would correspond to on the 1150 diagrams etc, that doesn't sound right.
A missing pin (that should be there, not simply a gap in a layout) is never a good thing - and may well be the issue.

If it's 'mangled', attempt to straighten it out. If it's outright missing, RMA the board - that's a problem.

Whether it's specifically related to your memory issue or not, that will likely cause you issues down the road.

It's possible the RAM module is faulty, but it's entirely possible it's not fully seated - RAM takes a little more force than a lot of people expect. Just ensure you have it lined up properly and in the correct orientation to avoid damage to the module or the board.

A 'new' MB unfortunately doesn't rule it out. Almost any component can be DOA.

Another thing to consider - if you have bent pins in your CPU socket, that can interfere with the memory controller and result in RAM not being detected.

I would attempt to reseat the RAM first. If that doesn't work, reseat your CPU and straighten out any bent pins (if there's any).

If neither of those options work, you should probably proceed with an RMA. RAM is a cheap/easy replacement though, so consider picking up the cheapest compatible RAM you can find initially to test with.

If a board supports DDR3 1600MHz, it supports 1333MHz in all but the rarest of cases.

If you actually look at the spec for the board it supports 1600/1333/1066 DDR3/L

Thanks, i'll visit a friend tomorrow who has ddr3 slots so i can test the module to be 100% sure that it's not the ram and then i'll contact the seller .
