 Topic: No signals and reboot: X399 Phantom Gaming 6Posted: 07 Jul 2019 at 6:07pm |

Hi there,
I have the following setup: CPU: Treadreaper 1950X RAM: HyperX HX424C15FBK4/64 (4x16) GPU: Nvidia GEFORCE GTX1080 PSU: Aerocool Strike-X 1100W Memory were set in 4 channel mode (D2, C2, A2, B2). PC boots without without video signal and without any "beep" sound (I've just realized that there is no speaker on this mobo). All fans and leds are on. It works 30 seconds and then reboots. I tried to eject all peripherals, ssd disk, video card and ejected all memory and tried to insert one by one, but result is always the same. I tested PSU with different PC - it works. GPU works too. I'm kinda confused. How it's possible to make mobo without bios speaker and dr.debug display? How to debug it now? |

Hi!
Leave only the GPU inside and 1 stick of RAM in A2. Re-seat the CPU, check all cables and connectors twice. Clear CMOS and try booting now. |

Just tried, but unfortunately the same result - 30 seconds without signals then reboot. |

Hmm, strange.
At this point it could be anything - CPU, PSU, mobo, you name it. Can you source some beeper, hook it up to the mobo header and see if you get any beeps? Or maybe get the mobo outside the case and try it on the table? Some pics may also help us spot something you are missing. |

As I see there is no place to set speaker from another mb. My mobo is already on table =) Well, I will continue my tries tomorrow and will make some photos.

Well.. It was a bad memory. All 4 stick. I still can't believe in it. But it's true. Warranty service approved it was defective. I can imagine that 1 stick is bad, but all 4!? Without any visible damage. Shop replaced it and now my system boots.
But I still can't understand why this mobo doesn't have any debug display/led or speaker. It could save me a lot of time if I could see that it's memory error. |
