Device failing to show output via DP and HDMI, then restarting without any visual output.
DIMM has become quite affordable lately, which is why I decided to purchase a kit. I plan to test using two out of four of my existing drives today and observe the results. I’ll follow up with a confirmation once I have more information, though it could take several weeks depending on how often I need it.
Okay so here's another one from me after this thread . TL;DR: PC kept losing display signal and rebooting, all replies suggested memory issue. By the end of it, had a couple of solutions. So just for context, my original kit of memory was 4x8GB G.Skill TridentZ Neo 3200MHz CL16. According to some, 4 sticks is often more taxing on the memory controller and board than just two (correct me if and where I am wrong). So I ordered a kit of 2x16 GB G.Skill TridentZ Neo 3600Mhz CL16. This was an oversight as a cursory Google seemed to suggest that the maximum memory speed for B450 boards is greater than 3200MHz, but I think my board in particular is limited to 3200MHz w/ D.O.C.P. profile enabled. I assume it's fine to use the 3600MHz sticks set to 3200MHz. So I installed the new memory kit, booted my PC up, entered the BIOS, and set it to 3600Mhz. After looking in, things seemed okay, so I ran with Windows Memory Diagnostic test. Unsurprisingly, the test detected memory errors. After logging in on the second restart, the system encountered a BSOD. I don't remember the error code (sorry, I know that's not helpful, but I think it's safe to assume what the cause of the BSOD was), but I restarted and set the memory to the standard D.O.C.P. profile (3200MHz) in the BIOS and booted up. 3200MHz was stable although gaming performance seemed worse. After foolishly doing a bit more tinkering trying to find a stable speed that was higher than 3200MHz. I also decided to enable Resizable BAR, but when I saved and exited, my PC encountered a seemingly fatal issue. Upon startup, the system would enter recovery mode and attempt to repair the installation which was never successful. When the recovery mode failed to repair the installation, the system would BSOD with the BAD_SYSTEM_CONFIG_INFO error. I could still enter the BIOS. I ended up doing a system restore to a restore point from a week ago and everything seems fine. I rebooted, and entered the bios to re-enable the D.O.C.P. (aka XMP profile).

Windows version: Windows 11 64-bit So what caused the BAD_SYSTEM_CONFIG_INFO error? Did I not let the system get used to new timings? I tried a variety of memory speeds between 3200 and 3600. 3333MHz appeared to actually be stable, and I increased it without running another Windows Diagnostic Memory test. What I still need to do is install the previous 4x8GB kit and run the memory test to confirm that there were memory errors that were perhaps causing my issue as outlined in my previous thread. Yes I am a huge fool for not doing this off I will not be increasing the memory speed of the 3600 kit past 3200MHz but I was curious to know if re-enabling Resizable BAR caused an issue. I know that you have to disable CSM when enabling it. Hope I haven't forgotten anything - the whole ordeal was traumatising lol.
I put in the 2x16GB unit and the problem seemed to stop for a few days... then it started again. I ran memory tests and believed 3200MHz with the DOCP (XMP) setting was stable. The earlier 4x8GB model worked before this issue, but it matches when I switched to Windows 11. Could it be an operating system problem rather than a hardware one?
I understand. I'll also experiment with the on-board graphics display for a few days or weeks to observe the results.
Here’s a concise summary of your situation:
The PC suddenly loses display signal and freezes, locking up at random times. It works with any monitor or connection type, but performance drops significantly. The system runs Windows 11 64-bit. Recent hardware includes a Corsair HX750i PSU, an AMD Ryzen 7 5800X3D, a GeForce RTX 3080, and a G.Skill memory kit. BIOS is 3802.
You’ve ruled out power supply issues by replacing the memory and checking for errors at high speeds. The problem persists even under heavy gaming loads, so it’s unlikely the GPU or PSU is the cause. You’re considering either swapping the PSU (a cheaper fix) or replacing the motherboard (which would require a full system reset). You’re unsure if the noisy 2000rpm fans are contributing, but suspect they might be drawing too much power.
Your main concern is the motherboard, though you’re open to other possibilities.
I didn’t manage to grasp it clearly, so I’ll save the screenshot for later. I’m hoping it catches someone’s eye.
