d6 error on MSI Meg X570 Ace when installing a new GPU during afternoon setup
Hello, thank you for your message. I recently upgraded my system with a new GPU and encountered some issues during startup. The error codes displayed were D4 and D6, indicating no optical device was detected and the VGA light remained on despite attempts. Although the PC started normally afterward and recognized the card, games and other functions didn’t work properly before the GPU installation. I ran DDU to check drivers and updated them, but the problem persists. I’ve connected the power cable correctly using a 3PCIE cable, yet it still doesn’t boot properly. When I shut down and restarted, the D6 error reappeared. My system shows the GPU details, but everything seems fine otherwise. I also mentioned updating my motherboard BIOS to the latest version. Could you help me resolve this?
Right now everything is running smoothly on this PC. However, when I power it off and turn it back on, the D6 code shows up after a short delay before it restarts and works correctly. Do you have something similar installed on your device?
The lack of optical components in current systems is unusual since DVD drives are rarely found today. You might want to set the BIOS to indicate no optical drives are available. Also, turning off Fast Boot in Windows can help avoid sleep-related issues and is beneficial with modern processors. Good luck!
Apologies for the error. The D6 code indicates that no console output devices were found. The VGA light staying on suggests the PC isn’t detecting the GPU. I saw some discussions about possible cable issues, but I’ve tried DisplayPort and HDMI cables too. My monitor is a Samsung G5, a gaming model at 144Hz. As mentioned earlier, once the PC boots, everything functions correctly—Windows recognizes the GPU, and benchmarks run smoothly even in games like Counter-Strike 2 and Roblox. It maintains around 144fps at 1440p with ultra settings, and I haven’t encountered any problems. In the Advanced Monitor Properties, it shows AMD Radeon RX 7900 XTX bus PCIe 47 and confirms the device is working properly. I can perform overclocking and underclocking, and everything operates well. During games, power consumption stays near 400W with temperatures around 60-80°C. No crashes have been observed so far; only a debug D6 message appears when the system starts and then shuts down via the PSU button. After closing it, I restart and it starts normally.
