My latest RMA-Story with Gigabyte
#This post was written with the help of AI for translation-purposes.
>TL;DR:
Gigabyte Support tried to downplay a hardware-related issue by simply disabling the protection mechanism. It was assumed that the display error regarding the VRAM amount was the cause of the problem. After a well-founded objection, a replacement for the card was arranged. The replacement GPU was delivered in terrible condition.
Hey everyone.
Today I want to share my ongoing RMA incident with Gigabyte.
I am currently fighting a battle over my broken RTX 4090. It died from a clear VRAM failure; not caused by me, but likely just through material degradation, voltage, temperatures, or whatever else. The fact is, I had a hardware problem and turned to Gigabyte support, hoping to get it resolved quickly and easily.
I want to share my experience with you today, structured a bit like a short story. I tried my best to write it in a way that both tech-savvy folks and non-techies can easily follow along.
I hope you enjoy the read. Maybe you have similar stories? I would be really happy if you shared your own experiences in the comments below.
Prologue: The Silent Black Screens
It all started in early March 2026. I was just having a good time playing a heavily modded session of Fallout 4. Suddenly, my screen went completely black. It wasn’t your typical system crash where the PC reboots or the audio starts looping aggressively—the speakers just went quiet, and the screen went dark.
I was a bit skeptical, so I just sat there and waited. After a few minutes, my regular Windows desktop simply reappeared. The game had closed itself, but there were no error messages, no weird visual artifacts, no driver crash pop-ups. Nothing. I didn't think much of it, assumed it was just a random mod conflict, restarted the game, and kept playing.
About half an hour later, it happened again:
Black screen, a short wait, and back to a perfectly normal desktop.
Still no graphical glitches or artifacts whatsoever.
At this point, I decided to look a bit closer to see what was actually happening in the background. I opened the Windows Event Viewer to check the system logs. That’s when I noticed several errors pointing directly to my GPU. The most critical one was a hard hardware error reported by the Nvidia driver itself:
At
>\Device\00000106
GDDR, Uncorrectable DRAM error in FBPA 5 subpartition 1 physAddr 0x045f2840
Chapter 1: The Troubleshooting & The Missing VRAM
Working in IT, I know my system inside and out. My rig isn't just for gaming; I also use it for local AI research and testing on a smaller scale. Because I need maximum stability for those workloads, I had manually enabled the ECC (Error Correction Code) state for my RTX 4090 in the Nvidia Control Panel about two years ago, and it has been running like that ever since.
Since I knew an "Uncorrectable DRAM error" in the Event Viewer is a massive red flag, I decided to dig deeper into the logs. Sure enough, I found two more errors pointing to the exact same issue:
>Error_ID: 14
Event_Data: \Device\00000106
Row Remapper: New row (0x00000000045f2840) marked for remapping, reset gpu to activate.
>Error_ID: 14
Event_Data: \Device\00000106
GPU recovery action changed from 0x0 (None) to 0x4 (Drain and Reset)
I started researching what "Row Remapping" actually means.
Long story short:
The Nvidia driver registers a specific chunk of memory as faulty and physically blocks it during boot. This prevents the system from accidentally writing into that dead chunk during normal operation, which would otherwise crash the whole PC.
When I read that, my hair stood on end. If a chunk is permanently blocked, my total available VRAM must be lower.
I distinctly remembered my Task Manager always showing 24 GB of VRAM. I panicked, opened Task Manager, and checked the dedicated GPU memory.
Lo and behold: I was suddenly sitting at exactly 22.5 GB of VRAM. 1.5 Gigabytes of memory had just been sliced off to keep the system stable.
I just thought, "What the f***."
The SMI Logs Proof
I needed hard proof to confirm this, so I turned to Nvidia's command-line tool, nvidia-smi. I ran a detailed report, and the output confirmed my fears. While the volatile errors (for the current session) were at 0, the aggregate (lifetime) logs showed the undeniable hardware failure:
>==============NVSMI LOG==============
Timestamp : Sat Feb 28 08:42:29 2026
Attached GPUs : 1
GPU 00000000:0A:00.0

Current : Enabled

DRAM Uncorrectable : 0
Aggregate

The "Aggregate DRAM Uncorrectable: 2" was the smoking gun. My VRAM was physically dying, and the driver was amputating pieces of it to keep the card alive.
Chapter 2: The RMA Process & The Battle with Support
After gathering all the logs, screenshots, and information, I decided to contact Gigabyte. I had registered my card for the extended 4-year warranty right after purchase. Since I live in Germany and the card was in its third year, I had to deal with Gigabyte's manufacturer support directly rather than the retailer (MediaMarkt).
I filed an RMA request with the German support team. They sent back a form asking for a summary of the error, serial number, and proof of purchase. I did exactly that and received an RMA number. I was told to ship the card to them. I carefully removed the GPU, packed it into its original packaging, and documented everything with photos. The card was in absolutely pristine, mint condition—it looked brand new.
Then I waited. Three weeks passed with the status stuck on "Processing." When I finally asked for an update, Gigabyte sent me screenshots claiming:
>"No error found (NTF). We are returning the card."
Their excuse? They claimed the missing VRAM was just the ECC function taking up space for error correction. While that's technically true for RAM, it doesn't work that way for VRAM without losing capacity unless there's a hardware failure.
I knew that before the crash, I always had 24 GB shown even with ECC active.
I even crosschecked on a friend's RTX 4080 with ECC also activated, but still shows the full 16 GB of VRAM.
I refused to accept their findings. I looked at their "test" screenshots and realized they were running generic stress tests on a system with an Intel i5 CPU that couldn't even push the 4090 to its limits, let alone systematically test the memory. They basically just turned off ECC, which reset the blocked rows, making the 24 GB reappear in Windows, and claimed it was fixed.
I pushed back, provided instructions on how to actually test it (using MATS/MODS or OCCT), and told them they need to bomb the memory with read/write operations to provoke the failure.
After another week, Gigabyte caved and offered a replacement: an Aorus Master RTX 4090 (Keep that in mind for later...), since my Gaming OC was "no longer available." They called it "refurbished but functional." I accepted it because their alternative was simply sending back my broken card. I thought at least I'd get a working, equivalent product. Boy, was i wrong...
Chapter 3: Disappointment and Disillusionment
After over two months of back-and-forth and patiently waiting, I finally received the package with the RTX 4090 Master inside. Today, on May 11, 2026. From the outside, the shipping box looked completely undamaged, so I opened it up.
Inside, I found the exact same black box I had originally used to send my RTX 4090 Gaming OC to Gigabyte. It still had the same tape I used, just re-sealed with a single new strip, and the RTX 4090 Master was practically squeezed inside.
I didn't think much of it at first. I pulled the card out to inspect it. At first glance, it seemed like a decent card, but as we all know, those anti-static bags are usually dark greyisch or blue-isch and blend in pretty well with the dark color of the GPU. But looking closely through the bag, I noticed something was off.
It looked... bent. Like it had a slight curve pushed inwards.
I took it out of the anti-static bag and inspected it from all angles. I looked at the corner where the anti-sag bracket is supposed to attach, and it didn't line up. It was physically bent. A piece of metal was literally sticking out. I checked the cooling fins and saw that in some places—especially right next to the high-power connector—parts of the heatsink were also bent. Then I checked the parallelism between the cooler and the backplate and noticed massive irregularities; in some spots, they were closer to each other, in others, the gap was wider. The backplate itself was sagging. It looked as if someone had installed the GPU and just dropped something heavy right on top of it.
Then I looked at the thinner part of the card where the third fan is located. It wasn't just slightly warped; it was severely bent. There was a literal N-shaped crease in the metal.
After the initial shock, anger and absolute disappointment took over. I immediately photographed and documented every single bend, crease, and scratch. I replied directly to the RMA email thread, explicitly stating that the graphics card is not free of material defects and that I refuse to accept it.
They promised me a "refurbished and functional" replacement, not a physically mangled safety hazard for my pc. I don't want to risk, that the 12VHPWR-Connector starts burning inside my case, because PCB is clearly warped arround this connector.
Honestly, I am beyond disappointed with how Gigabyte handled this entire situation. They tried to twist facts, gaslight me, and treat me like an idiot. And when I fought back, they tried to sweep the problem under the rug by sending me a visibly damaged, structurally compromised card to get rid of me.
I understand the current state of the world and how incredibly expensive hardware is right now. But I also spent a massive amount of hard-earned money to afford this GPU. I have rights as a consumer. The extended 4-year warranty was the exact reason I chose Gigabyte over Asus, Zotac, or anyone else.
I’ve had good experiences with Gigabyte in the past, buying their products for 15 years since I was a teenager.
But now, that one time I actually have a critical issue with one of their most expensive flagship products, Gigabyte showed me my true value to them:
>Absolutely nothing.
As long as you hand over your cash and keep your mouth shut, you're a "good customer."
But the moment you point out flaws in their repair or diagnostic process—even when you're literally helping them do their job—they try to mislead you just to save face and wiggle out of the warranty trap they set for themselves.
Epilogue: My Advice to the PCMR Community
If any of you are dealing with a similar issue, I can only give you this advice:
Hold your ground.
Don't let customer support brush you off or gaslight you.
If you feel something is wrong with your product, and you've tested and documented everything to the best of your ability, stand up for your rights.
This day and age, our dignity and our own integrity are sometimes all we have left.
We aren't crazy, and we aren't clueless kids anymore.
As an adult who actually understands technology, do not let them belittle you and talk their way out of it.
Since I received the card today, on May 11th, I immediately reopened the RMA case this very same day. I am now eagerly waiting for Gigabyte's reaction to the pictures and documentation, and to see what they have to say in their defense.
If they try to weasel their way out of this or claim they have fulfilled their duties, I will explicitly reject that and very likely take legal action, as I firmly believe they are trying to dodge their contractual obligations.
If anything else comes to light regarding this situation, I will gladly keep you all updated here.
Thank you for your time.
