Motherboard Error Code D6 on ROG motherboards indicates a specific issue.
Hi all, I am trying to build a computer and I am getting the error code D6 when turning it on for the first time. Here is the build: ROG Strix Z690-E Gaming WiFi Intel i5-13600K Trident Z5 RGB DDR5 (2x16GB) Gigabyte Gaming OC 12GB 4070Ti Seasonic Prime TX-1000 WD_Black SN850X 1TB NVMe SSD Noctua NH-D15 NZXT H5 Flow When I try posting the machine after building it, the graphics card lights up and the fans begin to spin, then maybe 5 seconds later the fans stop spinning and the lights turn off. The motherboard then finally lands on error code D6. (Note: the only things plugged in are: the power cable, DisplayPort cable, usb keyboard, usb wireless mouse dongle) Things I have tried so far: Unplugging the GPU and using the iGPU as well as unplugging and reseating the GPU. Result: error D6 Using the Seasonic included 12VHPWR as well as the Nvidia branded 12VHPWR to pcie psu cables. Result: error D6 Reseating the RAM as well as using only one stick of RAM. Result: error D6 Reflashing the bios using BIOS Flaskback as well as clearing the CMOS using the Clear CMOS button. Result: error D6 I don’t have a separate motherboard that works to test the GPU, but because I get the same error message when I try to use the integrated graphics on the cpu, I suspect it is not the graphics card fault but instead the motherboard. Is there any other troubleshooting measures I can try to take before RMAing the motherboard? Thank you in advance EDIT: The issue has been resolved but I do not know exactly what fixed it so Ill just say what happened in case someone has a similar problem. After trying different things to no avail, I tried turning off the hybrid mode (no fan) on the power supply and suddenly the iGPU started working. I went through the Windows 11 install process and updated the nvidia drivers (Windows was detecting the gpu but when I tried to switch to it, it did not work). Then I tried moving the HDMI cable plugged into the motherboard down to the GPU (I had primarily been using DisplayPort on the GPU) and it worked. I then tried unplugging the DisplayPort cable and plugging it back in and it finally worked. Im not sure where along the way the GPU started working but hopefully this helps
