I have two GPUs, one of them is an RX 6700 XT, and another is an RX 480. Other specs are listed in the respective section and it's all up to date.

The latter works perfectly under any conditions.
The former, however, sometimes fails to deliver image after the cold boot. It's not consistent, yet it happens. If the RX 6700 XT boots then I can torture it all I please and it will be rock solid and never fail no matter what load I give it (despite being overclocked). Last gaming session took about 7 hours without a second of stoppage time, flawless experience. But when I boot it cold...

What does not affect this behaviour:

• Updating the BIOS of motherboard and vBIOS reflashing;
• Reseating everything;
• Changing CPU/RAM;
• Changing PSU;
• Changing monitors and cables (tested both DP and HDMI, 3 of the latters);
• Resetting the CMOS;
• Changing PSU PCI-E cables;
• Cleaning ports and other stuff with isopropyl alcohol.

Didn't try changing Windows settings because it also happens when there's no drive with an OS installed whatsoever.

I know software measurements of voltages aren't particularly accurate but readings are very far from being suspicious. Temperatures are also nothing to be worried about with the hottest reading being 88C on the CPU and 99C on the GPU hotspot.

Is my GPU meeting its demise? RMA is not an option, I'm out of warranty.

i have had this happen on my 6950 xt. try turning ur monitors off/then on after u give it time to boot . the image for me was there after i cycled my monitor. its may not do it for a long time then it sems it goes thru a "phase". also some usb devices will cause this especially seagate external drives .. try booting with just keyboard and mouse then see

Doesn't help, tested a couple hundred times already.

I virtually don't have anything but them already. The only devices connected are LAN, KB, mouse, 3.5 mm basic mic, and 3.5 mm headphones. Doesn't matter if I exclude everything but mouse and KB.

id rma then whilst u can if it still continues ther culprits at work. o i just seen u cant my bad. id boot with tha later and use 6700 in os /game
 
I remember I once had a similar problem with a 780 Ti. I eventually pinpointed the issue to temperature as it would only occur during the winter on colder days.

It's a huge longshot that you also have the same issue but it'd be worth a shot trying to warm / raise ambient temps if you have low ambient temps.

makes sense .. coldbugs cause lots of issues. hope his mem isnt failing

Hi,
I've had this issue
The unplug and replug monitor worked usually
Other times the display was on a hdmi tv that was off

But in the end it was a bad sata connection.
 
i love when room is thatt temp perfect for some hours of gaming
I prefer having around 25C/77F but it's choosing between two evils. Cosplaying George Floyd, I'm not a huge fan of. Windows are open constantly despite -5C/23F to -15C/5F outside so I could actually breathe fresh air and have my brain at least pretending to be working.
But in the end it was a bad sata connection.
That's something I didn't think of. Will try a different cable, thankfully I got about 40 SATA cables more than I actually need.

Hi,
Actually I didn't need a new cable I just r&r them like the monitor bit
Guess they got weird during a move I do fuss around a lot water cooling/ cleaning rads/...
 
That's definitely the case, my room is currently at ~12C/55F. But I don't think it's too cold.

I agree, that shouldn't be cold enough. Typically I'd recommend breadboarding the system and only hooking up only what you need (in your case just the CPU, motherboard, 1 stick of RAM, GPU, and 1 monitor) for hard to pinpoint issues like this but given the infrequency of the issue that is not really feasible unfortunately.

Does your BIOS support forcing certain PCIe versions on your x16 slot? Might be worth it to try forcing PCIe 3.0 to see if that has any impact. Perhaps check the spread spectrum as well and invert it's current state (of course after you've tried forcing 3.0, one at a time to isolate the source of the issue). Sometimes that can be beneficial.

I always disable this function but in case of my mobo, there was no such toggle in BIOS.

Not sure, will give it a shot.

Currently successfully cold booted 8 times in a row after changing a SATA cable. Yet it could still be a coldbug.

Shutting PC down, gonna take a nap. We'll see how it boots in several hours.
 
Hi,
How did it go ?
 
Some monitors have power saving features built-in. You can try disabling them in the monitors menu.

This is irrelevant because I have a display that doesn't have any power saving thing whatsoever and it still doesn't see anything, the issue is on the side of GPU.

Just turned my PC on without a hinch. Why did it polterheist...

Hi,
Gremlins
Hell we all fuss around the pc so anyone's guess but sata cable clips don't always work good on ssd/ hdd's
Other weird one is their power cable connections to.
PSU is usually pretty good but not really on the hdd or ssd.

You are describing something similar that happened to me with my old RX 5700 XT. sometimes it would not display an image on boot. i had to unplug the monitor, wait a few seconds, and plug it back in and then a signal would be detected. It was an LG monitor which eventually stopped displaying a signal and is now e-waste. If you can, try a different monitor to see if it happens.

I tried SIX various displays, two TVs included. All of them behaved the same no matter what cable and interface I use. I highly doubt they all decided to pass away.

Well you have your answer then.

Maybe a poop solder joint.
 
I don't. My PC stopped playing tricks and I still don't know why.

You do. Your GPU is bad. You won't know why because I assume your are not an electrical engineer with a background in micro electronics.
 
Your GPU is bad.
Then why does it work flawlessly for the last 30 hours?

That's right, I am professionally a writer, not a hardware specialist. Yet it doesn't mean I don't have a right to ask questions as to what went wrong and how do I fix it if it's possible.

Especially if you water cool a high end GPU with top exhaust.
