New GPU (7900XT) system keeps crashing.

[ElT]

@fs123 My day is saved and my happiness is immeasurable.

That was it. Simple as. Well, either it was the cables or the GPU really likes lying on its side 'cause I haven't put the case back together again yet. But I'm pretty sure it was the cables. I thought when I put it together it might be wrong but I figured "what's the point of having two 8-pin headers on the end of the cable if you could only use one?" and used the single cable for the sake of tidy management.

I still do not know why it worked for over a week on a single cable, including heavy load. So maybe it is that the computer only works when lying on its side. But anyway, it's been merrily working away for the last two hours and I've been able to complete the coding project my friend needed. I haven't tried gaming on it yet so I probably shouldn't count my chickens before they're hatched. But I am feeling much more optimistic now.

Thank you - you actually saved me a whole lot of hassle.

Good to know it wasn't 'bad AMD drivers' which is the usual accusation from many people. I've had AMD cards for over a decade and never had any problems directly related to the gpu.
Let's hope the issue is resolved. Please report back once you are sure it's was the 8pin cable issue since it can help others who may have similar problems.

Well I've just spent about 2 1/2 hrs gaming on it and it performed like a champ.

All this talk about incompatible hardware had me starting to panic. But it's good in a way - now if you get any other muppets on the forum like me, people will know to start with the basics!

It's crazy isn't it? As you can tell from my post count I don't often post, but having seen this issue first hand (on a Nvidia card at first) and then just trying it out on a friends AMD card after reading the above reddit thread it's the first thing i'd try for a lot of display issues which people suffer from, especially if the rest of the system is stable. I just feel the more people know about it the less hassle it will cause them as it is easy to roll back on if it doesn't fix anything.

Edit: For reference the system I initially had the issue with on a 3060ti now has an RX6900XT installed, it doesn't require the fix but it is the same install of Windows, the same cabling and at the time of installing the same PSU.

That’s some serious lurking
