D6 Error Z790-E - Continual Issues

[Z9Ryan]

Hi all, about 6 months ago I upgraded my PC with some new components. Below are the specs:

Motherboard: Z790-E 

CPU: i9-13900k 

RAM: Corsair Vengeance DDR5 x2 16GB 5600MHz

GPU: TUF RTX 4080

PSU: Corsair RM1000e

SSD: Crucial T700 1TB 11,700 MB/s

OS: Windows 11 Pro

I’ve had over the past 6 months, continued issues with games crashing etc. I’ve quite literally encountered issues, fixed them and then been hit by new issues a substantial amount of times. A lot of these issues pointed towards a GPU related problem. I now have a new RTX 4080 and 99/100 times I can’t boot and get a d6 error. I have:

1) Updated the BIOS

2) Re-seated the GPU

3) Reinstalled all drivers etc.

4) Re-seated all cables in the PC

5) Ensured the correct pin power cable is connected to the GPU

Nearly every single component in this PC is brand new except for the case and fans. What on earth can I do? I’m not computer illiterate and I’m comfortable putting a PC together. The endless issues are driving me insane!

At this point something has to be faulty such as the motherboard surely?

Hello, @Z9Ryan 

May I ask if your current model is the is the ROG STRIX Z790-E GAMING WIFI or the ROG STRIX Z790-E GAMING WIFI II? 
Regarding the scenario you described, we suggest trying to adjust the following settings in BIOS:
1. Set "SVID Behavior" in BIOS to "Intel's Fail Safe."

2. Disable MCE in the BIOS
3. Decrease CPU Ratio
Or you can try cross-testing with another CPU.

Additionally, we noticed the below threads that may have a similar scenario to yours: 
Mainboard Z690 Maximus Extreme (Mar-2022) with BSOD - exception violation // memory errors // etc
[SOLVED]Could it be the motherboard?
Please take a look for references if needed.

Thank you.
