Question Amd rx6700xt not showing on task manager and no gpu z info

[Blobwingz]

Hello, I've being having this weird issue on my RX 6700 XT. Firstly it won't display BUT when I put my old Vega 56 in and check DDU it shows that it installed drivers for it so I think that it's ports are broken and might just use a igpu as a display out for it.

So I've tried it on my friend's pc with a RX 6600 to test that theory and more weird things showed up.

1.When we turn on the pc since it's a msi board it will light up the vga on its "ez dubug led's" when the dp cable is plugged in to the 6700xt but will be gone when it's plugged to the 6600
and will boot after that

2. It installed driver, but when I check on furmark/blender/task manager only the 6600 shows as an available GPU it cannot see the 6700xt

3. Upon checking with GPU-Z, some fields are unknown or have like 0 of something.

We've tried to flash it's vbios at the end of out troubleshooting but still nothing same issue
Anyone know what the issue is?

The PC I've tested it on has a:
-ryzen 5 2600
-MSI B350 Tomahawk
-16x2 3200MHZ RAM
-GPU AMD RX 6700XT/ SAPPHIRE RX 6600
-GIGABYTE P650B

You see 0(zero)'s there, the GPU's a goner! You can confirm this if you see an error code 43 in Device Manager.

Why do you have another GPU hooked up to your PSU when it's not part of the build?

Sometimes it does, sometimes it does not code 43 and even when it does a simple disable/enable will remove that code 43

also that other gpu is for display out like I've said it won't display on the 6700xt soo we've used a 6600 on a riser as a display out

Hey there,

Have you tried cleaning the PCie slot out with compressed air. Some dust or lint may get in there and causes this very issue.

As above, have you 2 GPU's in the system?

Just to be clear the RX6600 works fine?

Are all system drivers, including chipset up to date? What bios are you running on the system?

Are you overlocking either the CPU or GPU?

Hey, yeah we've cleaned the pcie slot

And yeah 2 gpus in the system and the 6600 works greatly I'ma say

As for drivers there up to date but the bios I believe is old it cannot support Ryzen 4000 and above I think

And there's no overclocking on the system

But tomorrow I will test the 6700xt on a ASRock b450m steel legend system with a 5600G on it soo I'll update you guys tmrw what will happen

Update:
Yeah same issue on the b450m steel legend system

At this point i think there's something wrong it physically

I will just send it to a reapir shop here in our country which is highly reputable

Yes, that's pretty much all you can do. At least you have the RX6600 asa a stop gap. Not a bad stop gap at that

Let us know how you get on!

Very similar issue like when I had my C2Q Q9450 from AliExpress. In the end my assumption was the IHS was changed, and in CPU-Z fields like CV, FSB, and Multipliers were 0. Putting my old C2D E6750 in, everything worked well, but the Q9450 was a goner (he's now peacefully in a very cold river xd).

My assumption for this problem could maybe be chipset drivers, or an actual GPU issue. But I rather think it is the GPU, he could get a GT 710 for example and test all the PCI-E slots so he rules out the PCI-E problems. The PSU is not the issue since the PC wouldn't boot up the best if it were the PSU. I suggest testing it with some old GPU to fully rule out that it is a dead GPU.

If so, if it is in warranty, RMA it, if not, you can always keep it or sell it on E-Bay for parts and for a small profit of what you had before buying it.

He could just take it to a repair shop. Since the motherboard is not the issue it only can be the GPU.

I personally think that he can take it for a repair and to get information on what the issue is, but I would only maybe take out the CMOS battery for 10 mins, after that call it quits and just take it for a repair, there is not really an alternative to what can the fix be. Except if OP has a high education in soldering/electrical fixing then he can try fixing it but thinking of something else in my opinion honestly seems like a meh move.

Well, the OP doesn't need to do that, as they have an RX6600 already Which has been established working correctly.

Absolutely. However, if the GPU is under warranty having a repair shop fix it will void the warranty. Worth checking before making any decisions.

It's possible there is some damage to one of the capacitors or the traces in the PCB of the GPU. Only expert engineers can fix things like traces. But, you know what? Sometimes GPU's just give up the ghost.

Repair shop is a good idea after exhausting RMA options.

True, I agree upon this. He has the 2nd RX card, and that is certainly good for now, and great that it is working!

Yes, RMA/warranties tend to be like that.

Apsolutely, you may not know until the problem actually starts appearing.

Yeah, that's what many would make it to do/make as an alternative!
