Error D6 appears during startup, indicating a hardware or system issue.
Updated the processor from i7-8700k to i7-13700KF, which required a new motherboard and DDR5 RAM. Now I’m stuck accessing BIOS due to a D6 error, and using the 'KF' chip complicates troubleshooting because it prevents onboard graphics. Here are my current details: CPU: i7-13700KF Motherboard: ASUS z790 Hero (second unit after suspecting original was bad) Graphics: GTX 1080ti RAM: G. Skill Trident DDR5 6000MHz (plus other tested DDR5 variants) Power Supply: ThermalTake ToughPower 850W ATX Modular - 80PLUS GOLD Storage: M.2 Samsung 960 EVO AIO: NZXT 280mm AIO Water cooler I’ve experimented with two different motherboards, so I’m confident this one is the right choice. Graphics card functions properly on my previous ASUS Maximus X Hero board. It powers up and lights up. The VGA and boot lights appear on the motherboard, indicating a possible seating issue or graphics-related problem. I’ve checked various cables, display ports, HDMI connections, monitors, and PCIe slots. After removing the motherboard and testing a bare setup, everything confirms proper contact. I haven’t found the 6-pin connector, though it seems optional and I don’t own one. I’ve flashed BIOS, cleared CMOS repeatedly, but nothing seems to resolve the issue. The only remaining thought is that my CPU might be faulty—a rare occurrence—but I’m determined not to give up. All components fit, and I have a brand-new CPU ready for overclocking. Help would be greatly appreciated!
The D6 error indicates no console output devices were detected. This is usually due to the GPU being connected properly on both the motherboard and GPU side, as well as the power supply. The specific 6-pin you're referring to might be related to the GPU's power connector or a peripheral port.
Cables are connected properly on both the motherboard and GPU at each end. I replaced my old motherboard with a new CPU and DDR4 RAM using the same PSU and GPU, and everything starts up correctly. The attached photo shows where the 6-pin power connector is located. As mentioned, this setup is meant to provide optional power for x16 PCIe, which isn’t a major concern for me.
I've checked the GPU in every slot and repositioned it several times, even after removing the motherboard completely to secure it properly. This was done with both versions of the board since I replaced my old one after thorough troubleshooting. It feels like there might be a compatibility issue, but it’s unlikely and seems very improbable. I’m considering purchasing a budget GPU just to test it out. I’m certain this one functions perfectly.
It seems the GTX 1080 probably uses the entire PCIe power supply, so you may need to link the six-pin connector. Just remember it should connect to the PSU as an input port, as outlined in the Asus guide.
However, the Mb manual seems to specify PCIE X16 slots. It appears to be specific to ASUS, though updates could address this discrepancy. The design suggests support for heavy overclocking, as ASUS believes we're nearing a point where an 8+24 pin configuration isn't sufficient for GPU, CPU, RAM, and Mb. The 60W rating is puzzling since a 6-pin setup can only handle up to 75W. A powerful non-6-pin GPU would consume between 63-67W (GTX 1650).
This manual also references PD_12V_PWR for USB power delivery via Thunderbolt and USB-C, though only the top PCIe slot is x16 compatible. The lower slot remains functional. The PCIe interface handles up to 72W, making 27W irrelevant for power purposes. You can find a detailed explanation in the video linked in the attached post. This appears to be an ASUS manual error that needs fixing. Some users report success with this setup even using more powerful graphics cards than my 1080Ti, though I remain skeptical given the evidence suggesting it's optional.
