THREADS COMBINED, HIT THE LINK FOR MY LATEST UPDATE ON THIS TOPIC
The recent update of the chipset drivers hasn't resolved the issue yet. It's possible it might still be related to the problem.
I've shared this before, but the problem came back after some time. It involves the PC losing the display signal via DisplayPort and HDMI, causing the monitors—ROG Strix 1440p ultrawide and TUF Gaming 1440p—to go black. The system would either restart or remain stuck with black screens until I force a shutdown. Audio stops working during playback, suggesting a CPU or RAM problem rather than a GPU fault. This happens whether the PC is under heavy gaming load or when no apps are running after boot. Stress tests with Unigine and high GPU power usage didn’t trigger it. Demanding games don’t seem to cause this either, and the PC runs at full capacity otherwise.
My specs: Corsair HX750i 750W 80+ platinum PSU, Asus B450 TUF Gaming motherboard, AMD Ryzen 7 5800X3D, ASUS GeForce RTX 3080, 12GB ROG Strix OC with 8GB RAM, G.Skill Trident Z Neo 3200MHz, CL16 EKWB, BIOS v3802. I’m using Windows 11 64-bit.
What I’ve tried:
- Rolled back Nvidia drivers
- Clean uninstall and reinstall Nvidia drivers
- Reseated RAM (resolved the issue, but it happened multiple times)
- Checked all connections at PSU
- Tested all three monitors via HDMI/DisplayPort
- Tried booting into BIOS to see if it’s in there
- Ran stress tests with Unigine and high GPU load
No power draw from components seems the issue, but the inconsistency suggests something else. My G.Skill RAM lights are very erratic—maybe that’s the cause. I’m wondering if the DIMMs are bad or if the G.Skill app is malfunctioning (I’ll uninstall it for a week). The CPU is solid, thermal paste is correct, and temperatures are normal.
The GPU was bought in October 2022. It’s possible it’s faulty, but the problem wouldn’t be as consistent if that were the case. I’m thinking about upgrading to a 7900 XTX and seeing if that fixes it, so I could return it for a replacement if needed. Thanks for your help!
Run the system using only the single RAM module inside the machine. Check for stability; since there are four units, it's likely one or a few are faulty, or the board is rejecting them.
It seems like you're questioning whether the issue stems from a single component or if it's a broader problem. You've already checked compatibility, so consider identifying the exact fault before deciding whether to replace parts or the entire setup.
it could be a faulty stick, a bad board, or the board simply doesn't accept those particular sticks in that setup and will function differently. Regardless, I'd opt for two 16GB sticks to reduce the number and ensure stability—start by confirming it works with one before adding more.
What confuses me is that I've been using those memory modules for about two years. I installed them in August 2021, right when I had a 3070 in my system, and I never faced any issues. Would it be easier to fill all DIMM slots for a cleaner look? Is it always tough to get four DIMMs to work well on the same board? Maybe my B450 is getting a bit outdated...
It’s tougher to operate four sticks compared to two, which means a greater likelihood of issues. As noted, it might simply be one stick that’s malfunctioning.
Your board can handle memory up to 4400Mhz, so the two 16GB modules should work well together.
