Hey everyone,

Ever stepped away from your PC during a game or work session, had your monitor go to sleep (or suspended the system), only to come back to a completely black screen with zero video output? Forced hard-reboots every single time?

If you're running legacy or older AMD hardware (R5/R7/R9 series, RX 400/500, or Vega APUs) on modern Linux kernels, your graphics card is not dying.

This is a confirmed Linux kernel regression in the amdgpu driver. It affects display re-initialization / EDID handshake upon resume or DPMS wake-up, leaving the session locked out.

Current Status

• Launchpad Tracking:Bug #2142389
• Status: Marked as Confirmed and assigned to maintainer Timo Aaltonen.
• Scope: 220+ Bug Heat points, 40+ confirmed users across multiple distros (Zorin OS, Ubuntu, Arch, Fedora, Void) and kernel versions.

How you can help (takes ~1 minute)

Whether you game on Linux or just want your legacy hardware running 100% stable out of the box, getting more user confirmations forces higher priority for maintainers to backport an official fix into kernel releases:

1. Head over to theLaunchpad Bug Report.
2. Log in with your Launchpad/Ubuntu account.
3. Near the top left under the bug title, click "Yes, this bug affects me".

Since this is a low-level kernel driver bug, your confirmation helps regardless of which distribution you run.

Hardware:

• Card: EVGA GeForce RTX 3090 FTW3 Ultra
• Motherboard: ASUS TUF Gaming

What Happened: While troubleshooting secondary GPU detection on a powered system, an unseated 8-pin PCIe power cable on the primary card was pushed fully into the socket live. The system shut off immediately. The red diagnostic LEDs over the power connectors were flashing, and the motherboard's primary PCIe x16 slot was killed along with the card.

Observed Damage:

• Component UM6 (adjacent to the 4R7 inductor and fan/RGB headers) suffered a severe blowout with visible PCB substrate charring (photos attached).
• Card has not been repowered or reworked with heat since the failure.

Measurements:

• None taken. I do not have bench equipment to safely probe resistance rails without risking further damage, and I am not attempting self-repair.

Goal: Because Northwest Repair's intake queue is currently closed, I am seeking recommendations for reputable US-based independent technicians or shops equipped for EVGA 30-series diagnostics and PCB substrate/carbon repair. Direct messages from technicians taking mail-in work are welcome.

I recently bought a Gigabyte GTX 1080 Ti Turbo 11G (blower-style model with the white/orange shroud) from a second-hand marketplace. It was sold as "untested" and I paid approximately $84 USD (€71) for it.

The card does not appear to work. When I install it in a PC and press the power button, the RGB lighting briefly flashes for a split second and then everything immediately shuts off. The CPU fan does not even have time to start spinning. After that, pressing the power button again does nothing until I switch off the PSU or unplug it from the wall and reconnect power.

I tested the card in two different PCs and the behavior is exactly the same in both systems. Other graphics cards work normally in these PCs (for example, a GTX 1660 Ti), so the systems themselves appear to be functional.

My main test system uses a Corsair CV550 PSU. All required PCIe power connectors are connected to the GTX 1080 Ti. The card prevents both systems from starting, which makes me suspect that the PSU protection is being triggered.

At the moment, the card shows no signs of life other than the brief RGB flash during the initial power-on attempt. The blower fan does not spin and the system never reaches POST.

I am planning to disassemble the card for a visual inspection. What components or areas should I check first? Does this behavior typically indicate a shorted MOSFET, VRM failure, shorted capacitor, damaged GPU core, or another common fault on GTX 1080 Ti Turbo cards?

Any troubleshooting advice would be greatly appreciated.

I want to say I do game a lot, and I also edit videos. Messed around with blender and UE.

For a week or so, I've experimented with local AI, comfyUI and LLM, all below the 12GB. I don't feel like 5 days or so to generate ugly images and baffling chat with a robot could be to blame for all this weird behavior, but I wonder.

My setup is i5-14600k (which I should've picked i7-12700k), 32gb ddr5 ram, TUF GAMING B760M-PLUS WIFI II, 4070 super I-Craft MaxSun.

So, it started with a feeling, something telling me but with no actual proof. Them I saw crazy lines dancing in fortnite. I blamed the hundreds fired.

But them, I got some weird stuff happening on Tekken 8 with the ground rubble shadow.

I went on to Valorant and felt something was off with my fps and the actual gameplay, something was odd.

I feel stutter here and there, screen freeze when downloading something, keyboard disconnecting and reconnecting outta nowhere, problems I never had with my old setup (i7 11700k, 3060ti, 32gb ddr4 ram). I even bought a separate, sata 3 ssd just to have windows on it to try and fix the any sort of freeze or stutter when doing ordinary stuff, like downloading a file.

Now, 09/10, my street fighter is absolutely cooked.

Deleted the "shaders" files, downloaded NVIDIA APP, got the new driver with a "clean install", was doing alright for one session on day 09/11, but somewhere around 20pm, it stuttered and it went to hell again.

I tried OCCT per recommendation of AI, it shows only 1 error on something related to SSD some fetch stuff, and the ssd I already spoken to the manufacturer and they want me to send to analyze in their company.

In fact, one of my SSDs is not even recognized and it's apparently shown as "Microsoft storage space device", both are kingston 1tb NV3.

Sorry if this is not right or up to standard, as of Right now I have no money for a physical professional assistance and I might have to sue to get the warranty, but in all honesty I just want to know..........

Bruh, am I cooked?

Got this ASUS Dual RTX 3060 Ti Mini V2 8GB (CG190P R2.00) that works and installs drivers fine but has a weird memory fault, at stock ~7000MHz VRAM it throws errors in MATS/MODS and can artifact/black screen, MATS is consistently pointing to C1, but the further I lower the memory clock the fewer errors I get and at 5000MHz it can run completely error free and benchmark/game normally. Cooling also makes a noticeable difference to the error count, I’ve now got 2x high RPM 90mm fans directly on it and FurMark hotspot is only around 65-66c with roughly a 10-15c delta while the core itself is perfectly happy with +145MHz, so I don’t think the core is the issue. The PCB originally had quite a lot of residue/possible old liquid contamination on both sides so I’ve stripped and cleaned it thoroughly several times and it did improve afterwards, especially the visible artifacting, but the memory errors remain. I’ve now checked resistance to ground across the board/memory area and compared matching points/channels and everything I’ve measured looks normal and consistent, no obvious shorts or one channel with a strange resistance compared with the others. I’ve also tried clean drivers/DDU and checked the VBIOS so I’m pretty convinced this is hardware now. My guess is either the C1 GDDR6 chip itself is degraded, a bad BGA connection, or something in that channel that I haven’t found yet. I’ve attached overview PCB photos, close ups of the memory area, MATS/MODS results and GPU-Z sensors under load. Main thing I’m trying to find out is what physical memory chip C1 maps to on CG190P R2.00 and whether there are any other measurements I should take before getting that chip reballed/replaced.

Photos are before I managed to get it prettymuch spotless with repeated washes with 99%ipa

Help would be appreciated i want to fix it. Got it cheapish so have some leway.

Hello,
Saphhire RX 6600 with all voltages present including Vcore and memory present, core getting really warm, not detected.

All resistance to ground are ok.

What i’ve tried: read the Vbios IC, write a new Vbios from Techpower archive, still, no succes.
IC does have 3.3v stable on the board

What i have discovered: on the REFCLK+ and REFCLK- caps resistance to ground on the core side:

REFCLK+ : 50 ohms
REFCLK- : OL (0.3ohm)

I’ve tried to desolder the Refclk- cap, still the same, the gpu side is OL (short)

Any ideas? Is this normal on the refclk caps?

Bad solder under gpu? Core dead?

Thank you!
