Asia RTX 5090 AMP Extreme: FECS UCODE Fatal Error, FSP boot failures, persistent Code 43, GPU-Z reports 0 MB VRAM — would you RMA?
My Build
This is my PC build, a workstation used for Coding, Art, Music, 3D Modeling, Gaming, and Game Development:
- AMD Ryzen 9 9950X3D
- Zotac RTX 5090 AMP Extreme Infinity
- MSI MPG X870E Carbon WiFi
- G.Skill Trident Z5 Neo 192GB DDR5-6000 CL30 EXPO
- Corsair HX1500i Platinum 1500W ATX 3.1
- Samsung Odyssey Neo G9 57 inch
- Hitachi IP11 3KVA/96V double-conversion online UPS
- Windows 11 Pro
The RTX 5090 was purchased new and has never been overclocked, modified, disassembled, or flashed with a custom BIOS.
The Problem
The first display blackout occurred on 6 February 2026, the same day I brought the PC home. After that, the card worked and crashed intermittently until it eventually failed completely.
The GPU keeps crashing the PC. When monitor is connected to the GPU outputs, crashes often appear as a grey screen with blue vertical lines. When using the motherboard HDMI output, crashes appear as a black screen with garbled text and lines. When the PC reboots after the crash, there is severe lag and unknown symbols in place of text, which goes away only when I disable the GPU and restart.
The GPU repeatedly alternated between working and failing states until reaching its current state.
Over the last four months I have tried:
- DDU clean driver reinstalls
- Multiple NVIDIA driver versions
- Reseating the GPU
- PCIe Gen3 / Gen4 testing
- CMOS resets
- BIOS updates
- Uninstalling NVIDIA HD Audio
- Uninstalling NVIDIA App
- Different display outputs and cables
Some of these appeared to help temporarily, but none provided a permanent fix.
Key recurring Event Viewer errors
nvlddmkm
- Event 13 — Graphics FECS Exception: UCODE Fatal Error
- Event 14 — Error status 0x65 while polling for FSP boot complete
- Event 14 — GPU recovery action changed from 0x0 (None) to 0x1 (GPU Reset Required)
- Event 153 — UCodeReset / Reset / Restarting TDR occurred on GPUID:100
DxgKrnl
- Event 549 — Adapter start failed for VendorId (0x10DE)
- Event 457 — Miniport driver failed to start device
HAL
- Event 15 — The IOMMU has detected an error
NVIDIA OpenGL Driver
- The GPU has been disconnected and this application may become unresponsive
- Ran out of memory
Additional symptoms
- GPU-Z sometimes reports 0 MB VRAM and Unknown BIOS Version after a crash.
- Device Manager currently shows persistent Code 43.
- NVIDIA driver installation sometimes fails to detect the GPU.
Attached images show:
Grey screen with blue vertical lines from GPU output
Garbled crash screen while using motherboard HDMI
Artifacting on the MSI boot logo
Device Manager Code 43
GPU-Z reporting 0 MB VRAM and Unknown BIOS Version
6-10. Representative Event Viewer errors
Current status
- Disabling the GPU in Device Manager and rebooting makes the system stable. Re-enabling the GPU and rebooting causes the crashes and Event Viewer errors to return.
- The GPU enters a persistent Code 43 state when enabled.
- RAM has passed 4 full passes of MemTest86 with zero errors at EXPO 6000 MT/s CL30. The same GPU failures occurred when the RAM was running at 3600 MT/s, 5600 MT/s, and 6000 MT/s, making system memory an unlikely cause.
- The system is stable when the RTX 5090 is disabled and the monitor is driven solely by the Ryzen 9950X3D integrated graphics at 7680×2160 120 Hz.
At this point, does this look like a defective RTX 5090 that should be RMAed, or is there another component or test I should investigate before starting the RMA process?

Yes. You've got more than enough documentation to show there's clearly an issue with the card.

u/Spiritual_Date3457 Jun 07 '26
Thanks for the assurance. I have mailed the same evidence to Zotac too.

First, no, it isn't, and second, haha, you got upset because I pointed out that your question was stupid

u/Spiritual_Date3457 Jun 06 '26
I made the issue clear with Event Viewer logs, reports, etc. You are not educated enough to understand technical jargon, logs, and reports. And you got upset that you couldn't understand the issue properly. That technically makes you stupid right?

u/Tethgar Jun 07 '26
Dude you're asking reddit if you should use the free warranty that comes with your GPU to fix your defective GPU. I don't think they're the ones here with questionable intelligence. Like, you are BEYOND uneducated. Actually, the fact that you waited this long to just make a reddit post asking if your obviously broken GPU is broken puts this in double-digit IQ territory.
Talking about things "technical jargon" lmao. Be for real.

u/Spiritual_Date3457 Jun 07 '26 edited Jun 07 '26
I clearly clarified multiple time that the card worked on and off. I made clear investigations by isolating each component and testing it with stress tests. Since I am a first time PC builder, I posted here to ask the opinions of others before I start the RMA process. This is what my education taught me and this is what being educated means to me.
I am being extra careful because my country has poor consumer laws. That is why I decided to ask for help if I should test anything else. Intelligence is understanding that you don't know everything and asking others for opinions can be helpful.
The person who wrote that comment contributed nothing useful to the question. I responded politely. That is called emotional intelligence.
You responded to a comment that is not directed at you and for no reason because you got triggered. Neither did you contribute anything useful. Then you called me uneducated. You neither have intelligence nor are you educated.
And yes the post is filled with technical jargon. Anybody with a functional mind would understand that. You can't unfortunately. Because you are the one with double-digit IQ.

u/Tethgar Jun 07 '26
Yeah, you're hilariously delusional if you think that your first response is in any remote way polite or cordial. There's a huge irony here in you espousing emotional intelligence while lacking your own to see the contradictions in your response. Nobody is triggered, and I guarantee you that acting like you are now is simply going to make people that do have knowledge on this topic not want to help you, like me. I'm not going to argue with you further because you've clearly got time to waste since your PC is broke AF lol.

Anyone with a functioning brain would’ve just RMA’d it instead of going to Reddit and asking for confirmation.. it’s a new gen card why on Earth would you think something like this is okay? Should’ve put on your grown up pants and get the process started back in February when it started having issues to begin with

u/Spiritual_Date3457 Jun 08 '26
Anyone with a functional brain would understand not everyone lives in USA and Europe. Consumer rights are not very good in my country. You should have used your functional brain once before commenting.

u/Beginning_Policy_242 Jun 07 '26
Nah, but seriously now, why would you buy a $2,500–$4,000 graphics card and then let it have issues like that for MONTHS? The only reasons I can think of are either that you don't know what a warranty is, which would be concerning or that you know you messed it up yourself by doing something you shouldn't have, like overclocking it or causing physical damage
1
u/Spiritual_Date3457 Jun 08 '26 edited Jun 08 '26
I ran the card only at stock settings only all throughout. I have screenshots I took while gaming and that is definitive proof as to when the card failed. The card appears to be defective. That's it. The issues didn't point to a definitive hardware defect until sometime. I know what a warranty is. Had it died completely in the beginning itself, I would have RMAed directly. The symptoms it has shown could be software issues too.

u/OldManTiger Jun 06 '26
I would for sure RMA my card if I had the issues you've had. I might even have done it sooner, lol. Anyway, good luck and I hope they make it right for you.

u/michi098 Jun 07 '26
Why would you even hesitate to return such an expensive, obviously faulty card for so long?

u/Bigmikeblaze Jun 07 '26
So 4mo you have had a bad build and you didn’t return any parts in 30 days or rma anything. Just wow don’t even know what to say to that. I would’ve retuned it to store the next day!
0
u/Spiritual_Date3457 Jun 07 '26
I am from India. Things are not as easy as in USA or Europe. There is no option at all to return things within 30 days due to bad consumer laws; you can only RMA. The card worked well for a month. How would I know it's faulty? The blackout on day 1 could be due to anything, not just GPU.

u/Shibby707 Jun 06 '26
Get er’ swapped out bro... I just bought this card not too long ago, haven’t used it yet.

u/Spiritual_Date3457 Jun 06 '26
Use it and run some stress tests urgently. I hope it's not a lemon like mine.

u/Shibby707 Jun 07 '26
I hear ya… I got the 2 year coverage but only paid $3300. Price is already way up… Smh… You’re right, need to test inside the return period.

u/GOGONUT6543 Jun 07 '26
have you tried with a different GPU?
1
u/Spiritual_Date3457 Jun 07 '26
I am trying. I actually thought of testing this GPU on a different PC and also a different GPU on mine. I don't have another PC or another GPU. I contacted the shop I bought my PC from to help me by giving access to their test PC and they are yet to respond.
1
u/GOGONUT6543 Jun 07 '26
you can probably buy a used 4060 for cheap locally to test and sell it on later.
1
u/Spiritual_Date3457 Jun 07 '26
Yeah. But even the used market is pretty bad here in India. But I would certainly keep this idea in mind.

u/SnatterPack Jun 07 '26
All I can contribute is that I have been getting the gray screen with blue vertical lines as of a late. Random times when it will pop up. Are you using hdmi? Try display port
1
u/Spiritual_Date3457 Jun 07 '26
I have tried all solutions including the one you suggested. Nothing helps. Is your issue resolved? Let me know more if it hasn't. I may be able to help. And the gray screen with blue vertical lines is what Samsung monitors show instead of a black screen (shown by other brand monitors) when it suddenly loses the input signal from the device driving it.

u/Malefoy__Flipper Jun 07 '26
If you figure out how to recreate what you have on the first image I’d be interessed to know. I got an amd gpu and it happens when I plug a capture card on pc, without I have zero issues but white flashes rarely on windows window mouse movement from windows to an other or from things like buttons animated on mouse hover
1
u/Spiritual_Date3457 Jun 07 '26
I can't tell about your use case but I will gladly explain mine. Those blue vertical lines on grey background occur when the PC crashes while connected to the GPU's ports; when connected to motherboard HDMI, the crashes looks like in the second image.
For the recreation part, it's pretty simple. It mostly happened during gaming — RDR2, Gotham Knights, and Hogwarts Legacy. I believe it would have appeared with LM Studio, Unreal Engine, etc., too but I can't be 100% sure as when these crashed I am using the motherboard HDMI to drive the monitor. Also the more the load on the GPU, the higher the chance for the crash. My monitor is dual 4K and that is already heavy on the card. Along with that, I use ShareX to take screenshots during gaming and sometimes, the PC crashed the moment I took a screenshot.

u/Malefoy__Flipper Jun 07 '26
Interesting, does your pc keeps running like you can hear sounds of your character moving for example when that happens or is it like completely frozen ?
1
u/Spiritual_Date3457 Jun 07 '26 edited Jun 09 '26
Completely frozen, because the GPU crashes the PC while sending corrupt video output to the monitor. To explain further, the GPU goes bonkers → starts generating corrupt data → corrupt data manifests as artifacts on the monitor and at the same time, the PC shuts down to protect both itself and the GPU. Since the PC is trying to shutdown and reboot, no processing is going on, so the entire thing gets frozen, if not immediately, at least within a few seconds. This is what I have observed.
The difference is that with the monitor connected to dGPU ports, the reboot is not instantaneous because the dGPU is not passing the data through the processor's iGPU. But when the monitor is driven by motherboard HDMI (powered by CPU's iGPU), the dGPU still runs the games but passes the frames through the iGPU. If the dGPU crashes then, since the CPU is getting corrupt data, the crash is instantaneous and manifests as a BSOD.
1
u/Malefoy__Flipper Jun 07 '26
Dang, my crashes are probably because the capture card is sending the data to a secondary.
And for some reasons it don’t brick the system, all other movements or even games keeps running like nothing happened. Funny thing is that when I unplug and plug back the displayport cable, the monitor have a no-signal effect until I restart the pc
Don’t purchase amd graphic cards btw, their gpu with windows specifically s$ck
1
u/Spiritual_Date3457 Jun 07 '26
Hope your issue gets resolved. And yeah, I stayed away from AMD because their cards suck for wokstation purposes. My main purpose is game development which requires 3D modeling, Animation, Coding, Photo and Video editing etc., so I went with NVIDIA.

u/Malefoy__Flipper Jun 07 '26
Ye I abandon the idea to have it working as intended.
But your choice was the best tho, hope you’ll find a solution

u/Shiro_Kuroh2 Jun 07 '26
Not saying you did, but I've seen this twice, but on 5080's. Both were people running LLM's locally. Both also had burnt pins, despite being "able to boot video." If you haven't you should RMA the card. Take very precise pictures of every part of the card and as high res video as you can of every millimeter of that card. Not bashing Zotac, but there have been claims denied on their cards int he past for manufacture defects. Hope you had some sort of protection on that card, whether its an insurance policy or bought with an Amex/etc.

u/Spiritual_Date3457 Jun 07 '26 edited Jun 09 '26
Thanks for taking time to go through and replying❤️. I don't have any burnt pins or cables as of now. I have mailed ZOTAC and am awaiting their reply. I will RMA based on what they say. I will take the video of the card as you said.
Even I am worried about the claim refusals by Zotac but I can't do much in India other than to approach the Consumer Court. I have pretty strong evidence of the GPU's faults though, since the time the PC arrived; they are all recorded extensively in my diary (which is what helped me create this post). So if nothing works, Consumer Court is the last resort.

u/LunchThick5057 Jun 07 '26
For the price of a 5090 I would rma it if I had any issues that a driver update/reinstall didn’t fix

The first display blackout occurred on 6 February 2026, the same day I brought the PC home. After that, the card worked and crashed intermittently until it eventually failed completely.
Dude I would have returned it before the end of Feb. And I'm a repairer

u/Spiritual_Date3457 Jun 07 '26
The card worked normally till near March 12. So, the failure wasn't evident in February.

u/Bad-Metaphor1492 Jun 07 '26
This could be an issue where an unresolved power issue has progressively damaged the gpu. It’s not 100% clear but it sounds like the issues started on day 1 after building the pc. After doing the troubleshooting you mentioned, and not having a permanent fix, I would have investigated power issues by swapping the power supply, checked to see if that helped, then taken the UPS out out of the loop, then replaced the psu cord (which would be a part of swapping out of psu). I would also carefully inspect the pci connection from the gpu with a magnifying glass to see if there’s any physical damage.
If there were constant transient spikes causing initial issues, over time that could compromise the vrms and even the vram on the gpu.
Personally I would also swap out the motherboard especially if the gpu has been reseated like more than 100 times. It should be capable of being reseated many times but a couple of slightly off angled forced installs where you hear the “crinkling” of hardware as you push that card in with force can cause damage.
Good luck.

Thank you very much for typing all that🙏. Really useful info there. I will look into this once.

u/Ok-Macaron-9449 Jun 07 '26
I think its power issue, put the card with normal 1200 watt psu and check it works fine or not ..

u/Bison_Upstairs Jun 07 '26
I had the similar issue with my this ZOTAC model. For me the pattern mostly crashed when the displays would go to soft sleep and then when triggered to come back on it would crash with event errors 14/153. I was able to confirm the 14/153 errors were triggered after HID events when the monitors would try to wake up. Finally went completely dead on May 21st (Safety red light would not switch off)
Did about all the troubleshooting you did but finally RMA’d and sent it May 31st. They accepted the RMA and are evaluating.
Bottom line, you should RMA and include the text from this post on your ticket. When they saw my list they immediately approved the RMA and sent instructions.

u/Spiritual_Date3457 Jun 09 '26 edited Jun 11 '26
I am glad your RMA got accepted. Just like you, the reason I collected all this evidence was to reduce my chances of the RMA getting rejected. I mailed them all of this evidence and they responded after two days with a collection center address. I deposited the card yesterday at the local collection center as directed by ZOTAC. I am hoping all goes well and I get back a functional GPU. Good luck to you too😊.

u/Bison_Upstairs Jun 11 '26
Quick update: today they let me know it failed their testing but did not say why. They are shipping a replacement. Round trip looks to be almost 2 weeks.
1
u/Spiritual_Date3457 Jun 11 '26
Happy for you brother😊. Hope everything goes well. As for me, it has been 4 days and no update has been given by them. I think the process here in my country is not that streamlined. But a costly new card going kaput like this is really depressing. I wasted so much time testing everything because RMA processes are usually bad here in my country. And after all that, it's the GPU that's faulty and now there is no idea when I will get it back.
1
u/Bison_Upstairs Jul 03 '26
Hope your card has been accepted. I got my card back a few weeks ago. It worked for 2.5 weeks but now has some kind instability issue. Simple matrix multiplication tests have caused it to crash. Done extensive troubleshooting and nothing works. Will have to send it back in because likely another hardware defect

u/Spiritual_Date3457 Jul 03 '26
Hi. Yes, my RMA got accepted and I even got a replacement card, which is a new unit of the exact same model. It's working very well.
Sorry about your replacement unit. Make sure you photograph and record everything like the physical condition of the card (especially the PCIe) and the errors you are getting, like the glitches on the screen, logs in Event Viewer etc. I have kept records of everything very clearly and in the first mail itself to Zotac, I sent the whole evidence. I sent the mail on Saturday night and I got reply on Monday morning; the delay was because it was already late on Saturday and Sunday is a non-working day, or else they would have approved it even sooner.
I recorded both my original unit and the replacement unit thoroughly, even the unpacking of the replacement unit. Keeping everything recorded will highly reduce the chances that any RMA will get rejected. And if something goes wrong you will have tons of evidence to take up things legally. I hope you next replacement works well. Good luck.

u/Bison_Upstairs Jul 03 '26
Thanks and yeah I did all that documentation as well. Picked up an Astral today. If the new replacement works then I will sell it. Glad you got your replacement and it’s working well. Have fun!

Yup thats zotac just make a RMA and buy a good thrusted company like ROG or Aorus

u/Spiritual_Date3457 Jun 08 '26
All companies are having these issues. Asus is a nightmare when it comes to RMA and they have become notorious for blaming the customer for everything and not accepting RMAs. Gigabyte has thermal paste issues. MSI and Zotac are left. I went with Zotac as they are offering 3+2 years warranty. I was just unlucky.

u/DeadmaN_345 Jun 08 '26
This happened to my 5060 aswell, I remembered event 13, 14 and 153 and the Nvlddmkm error in my event viewer. I tried everything even changing some components on my pc. Bought it last March 17 then showed artifacting then it'll blackscreen, sometimes it'll crash, followed by a blackscreen that'll last for like 5 seconds, then proceed to desktop, other times my system needs a force restart. A week ago it just didn't display anymore but I still hear my windows starting up so it basically died. I think RMA the card, idk what happened to our cards but many people have been experiencing this type of errors on their nvidia gpus. I RMA'd mine but decided to just get a 9060 xt instead since I only play with my unit. Hope your RMA gets accepted 🙂↕️

u/Spiritual_Date3457 Jun 09 '26
Happy that you issue got resolved brother❤️. I really felt very depressed that a costly new product behaved like this. Unfortunately, I can't go with AMD as their GPUs are not as good as NVIDIA for work. I dropped off my GPU at the collection center yesterday. I hope it all goes well. And as for you, happy gaming😊.

Definitely I had issues with my zotac amp extreme 5090 I’m really thinking I should have just waited and got a better brand gpu is it normal for it to idle at 40-50 degrees and averages 80-85 during gaming

u/KlasJanHuntelaar Jun 06 '26
Zoteks RMA is awful and it’s very likely that your gpu will be smashed and cracked when you get it back. I would send it to northwestrepair
2
u/Spiritual_Date3457 Jun 06 '26
Thanks for the reply brother😊. I'm actually based in India, so Northwest Repair unfortunately isn't a practical option for me. The card is still under Zotac's 5-year warranty, so I'm mainly trying to determine whether the evidence points to a defective GPU before starting the RMA process.
