DZ87KLT-75K + i7-4770 fails to init CPU

Hi,

I have the following brand new components:

- DZ87KLT-75K motherboard (manufactured in oct/13)

- i7-4770 CPU

- 2x8GB Kingston hyperX DDR3 1600 CL9

- Nexus RX-5300 PSU

- (no other components attached)

The system is stuck in a reboot loop and won't even reach the BIOS screen before rebooting (monitor gets no signal). There are no error beeps. The last error code on the diagnostic LCD's is 10 which means that the CPU is initializing. The error LEDs show the following:

- MEM Init flashes

- MEM Init stops flashing and stays lit

- CPU Init lights up

- The red CPU HOT led flashes once and the system reboots

The only attached cables are 20+4, 4+4 and the boxed cpu fan cable. I tried booting with only one RAM stick in slot 1 and I tried both sticks. I reseated the CPU and checked the pins (they are fine).

My question is: should I just RMA the MB, CPU or both or is there something I have missed when assembling the components? Are there any more troubleshooting steps I could try?

edit: I tried booting without any RAM sticks and got the expected repeating 3 long beeps. I also corrected the LED names in my post. It was the CPU Hot LED that flashes right before the reboot. But I doubt CPU heat is the issue, because that would cause beeps(?), and the CPU fan is properly seated and working.

Noboot, the issue could be related with the power supply you are using. Have you tried to use a different power supply?

On the following link I was able to see that your Nexus RX-5300 is not a Haswell ready power supply http://www.nxstek.com/Nexus_RX-5300_Modular_Quiet_Power_Supply_530W.htm http://www.nxstek.com/Nexus_RX-5300_Modular_Quiet_Power_Supply_530W.htm

You can also try some basic troubleshooting such as testing the system out of the chassis with minimal configuration. (Motherboard, processor, power supply, 1 memory stick)

Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system. http://www.intel.com/support/motherboards/desktop/sb/CS-028780.htm?wapkw=clear+cmos+battery# datetime http://www.intel.com/support/motherboards/desktop/sb/CS-028780.htm?wapkw=clear+cmos+battery# datetime

Just in case, remember that low profile memory is not supported by this motherboard.

I would say that you should start replacing the motherboard if you wish. However I recommend you to try the troubleshooting I provided you above.

KarimB, I noticed that Kevin_Intel is helping you in this thread, /thread/49305 https://communities.intel.com/thread/49305. He will continue assisting you in order to find a solution on this issue.

In the meantime, we could wait for NOBOOT, he may give us an update.
