X79 won't post

[harrywt44]

Hello I bought an i7 4820k as it was really cheap and I don't have that much money and for whatever reason X79 boards are so expensive so I got one of these Chinese X79 boards which from reviews done on them seem like okay boards so I buy one it comes today I put the chip which was pulled from a working system and then I wire it up and just on the mobo box I just want to test fire and it powers the board but no display my ps/2 keyboard flashes but doesn't come back and the board powers up then powers down in about 30 to 100 second cycles and endlessly repeats. What I'm wondering is if the board is bad or if it's a dead cpu but or if the bios isn't recognising the cpu and needed flashed I'm just at a lose as to why it isn't posting

 

What I've tried I've tried three gfx cards in different slots no change tried different ram and one stick in each slot not change I did add a board speaker and it won't beep just nothing I know the speaker is working but even with no ram in it which should make it beep still no beeps, I've tried remounting the cpu cooler see if it was a bad mount nope just power cycles. I will add on first boot everytime it does do a double boot so any help would be great appreciated

Bricked board? 

Ask for Refund. That's the first advice.

what power supply are you using?
