Rampage IV Formula X79 - Red CPU Q-led

[z3rum]

Hi all,

I've just put together a brand new build that fail to boot. I don't get any sound or debug led numbers, the Q-led for CPU go red immediately after power on and stay red. I've tried to reset CMOS using button on the back of mobo, reseat the CPU, switch BIOS, try with only one memory stick in D1, still no luck.

My components are:

- Rampage IV Formula X79 Mobo (Bios is 1305)
- Intel i7-3820
- 4x4gb G.Skill DDR3 PC3-17000 RipjawsZ Series for Intel X79 (9-11-10-28)
- Diamond HD7970 (connected to Cinema Display over DP)
- Seasonic X1050 Power Supply

Any help would be much appreciated.

Update: Added Bios version, tried with 1 memory stick

/Christian

If you've inspected the socket and it came out clean, try loosening a little your screws for the H100. Sometimes overtightened screws can warp the motherboard and result in the 00 QCODE.

I can try that, there were no Digits lit on the LED display, just the RED CPU light near the Power supply connector. One other thing, I have the large Power connector connected, and the 8 pin one by the CPU, I dont need to connect the 4 pin one as well do I?

Connect all the PSU connectors please friend, and make sure you have the EPS connector fitted and not a PCIe connector.
