Hello! I just got a new x399 fatality, because my previous board died and wasnt available anymore. I installed the 1920x threadripper as well as 64gb, 8x4gb gskill F4-3200c16q-64gvk. Also installed two m2 samsung 970evo After turning it on, I get the following error codes: 14/15 C2 and the board shuts off. I cant find more information online about c2, but 14/15 seems to be a Ram issue. I tried various settings with the ram, starting from none, to just one or two. If I turn on the PSU the red LED under the fatality metal plate starts of purple and turns into flashing red after a few seconds. any help is appreciated. Can it be that the board is faulty? thanks and best guben |

First of all, clear CMOS and pull the battery with power disconnected. Leave it like this for 20 mins or so then put the battery back in. Next, install a single RAM stick, the CPU and your GPU. Nothing else, no drives no add in cards. Power on the system with the RAM stick in slot a1, if it still gives an error try the next slot. Also, do not power off the system, sometimes there are several power cycles (PC turns on, flashes codes then turns off then back on again). -------------

| thanks for the answers and suggestions! Of course, I cleared the CMOS several times as instructed online. I tried with the minimal setup as well, only one Ram slot. I'll give it a shot with leaving the system on after it turns off. that seems the only option I have not tried yet. |

| as I ventured deeper into the testing, it might have been a faulty PSU, as for now the self test of my corsair PSU is failing. (which it didnt do before) |

| a recent update on this. I replaced the PSU and it was working now for about 2 weeks. Just now the display turned black and restart brought the MB into an neverending loop. never see any display. When opening the case, I see the LED on the AMD x399 chip is flashing red before I even turn on the Power. Its so frustrating with the whole x399 Build... any ideas what this could be? |

A red pulsing ring of LEDs around the Chipset heatsink? If you have not set your RGB then that is normal. Try clearing CMOS and double checking your power connectors. How reliable is your power? Is it possible you have over or under voltage coming from your power socket? -------------

thanks for the quick answer. why the hell would they make red as default ... :) I have a brand new corsair 1500W PSU, replacement for a faulty one. The PSU self test was positive. the board keeps resetting. I did a bios update to 3.8, now back to 3.5 which it got shipped with, doesnt seem to make a difference. I can enter the bios sometimes, could even boot up windows shortly, but it keeps resetting most of the time at random error numbers. Tried with less Ram and also just replace the Graphics Card, but also with no different outcome. The board is brand new as well and as statet was working fine for the past weeks. |

| to be specific, its a corsair AX1500i, but since the last one broke after about a year, I wont trust this and see if I can get yet another replacement. not sure what else it oculd be. |
