Aorus Elite B550 V2 Rev1.1 and Sapphire AMD RX6700 Pulse 4 beeps

[Kamui]

Hello there,

So the story is the below. My Sapphire AMD RX6700 Pulse 10GB burned one of the 2 fans so I send it back for RMA.
After some days the shop exchanged it with a new graphics card and when I put back the new card I get 4 beeps (1long, 3short).
I went back to the store and ask the service guy to install it at his PC (and use the x16 PCIE) and check if it works.....it WORKS GREAT!
After I tried change position of the GPU from PCIEx16 (1st slot) to PCIEx2 (2nd slot)...same beeps.
After that I put and ancient Radeon HD6850 to PCIEx16 and works fine (so slot seems to be ok)
Next tried the HD6850 to the PCIEx2 slot...works ok...AND ONLY AFTER i used the HD6850 on PCIEx2 and then exchanged to the RX6700....the card works!
So I tried put it back to PCIEx16 ....beeps again!
So if the card works properly in another systems and in my PCIEx2 slot, why it doesn't work on PCIEx16??!?! I am going crazy and I think something is happening with the motherboard.

I remind you that the old Radeon HD6850 works good on X16 so the slot seems just fine. Additionally the exact same model of Radeon RX6700 worked for 1.2 years just fine and after I got a replacement now it does not work but it's the EXACT same system!


What I have tried
1) Use 750 and 850W PSU
2) Hard reset BIOS (battery + jumper + hold power)
3) Clean contacts
4) Uninstall drivers (does not matter although because the problem is at BIOS POST)
5) Change PSU wires cause it's modular
6) Remove all other PCI(E) cards
7) Updated BIOS to the latest version

My system
Gigabyte B550 Aorus Elite V2 Rev1.1
Sapphire AMD Radeon RX6700 10GB Pulse
Corsair Vengeance LPX 16GB DDR4 RAM CMK16GX4M2D3600C18
AMD Ryzen 5 5600X 100-100000065BOX
PSU both Corsair CX750M and a CoolerMaster MWE Gold V2 850W

1st of all it's really fun that we are on official Gigabyte forums and all these days there is no official representative to suggest or help with the issue. This is really fun (NOT).

So I send the mobo as RMA to the store I bought it. The guy helped out and tested with 3 GPUs that he had available. The mobo works perfectly fine.

3 service centers, and they have tried 5 or 6 GPUs (2 service centers from the store I bought the GPU and 1 from where I bought the mobo). Some GPUs that have been tried are
nvidia 1080
nvidia 4070
nvidia 3060
AMD 6500...
I don't know their brands. All of them are working PERFECTLY fine with my mobo.

It's now obvious now that the mobo has NO HW issue BUT there is something that makes the current mobo with the replacement GPU Incompatible! Of course in such case you are the unlucky guy out of a 1.000.000 people and gigabyte won't even try to help. That is a lesson to be learned for my next mobo after 6-7 systems using gigabyte.

I am lucky because the service guy from the mobo store had just received an B550 Elite V2 as a replacement for another customer and he exchanged the 2 mobo. I am waiting for the "new one" (not really new) to check.

1 more update. A friend of mine has exactly the same mobo Aorus Elite B550 V2.

And it's not working at his PC either! The monitor stays black with no signal output. This situation going to make me crazy. He has an RX6600 which works perfectly fine, but this specific RX 6700 seems that it doesn't work on Aorus Elite B550 V2 like it's blacklisted.

The thing is this is a user to user forum. This isn't official support forum. Yes it is a Gigabyte forum. But isn't support from Gigabyte. There are only few US that do check here and there to see if there is any new topics.

I had something like this just happen to me. I had Gigabyte RTX-2070 on a board a ASRock B550M Pro SE. I had a EVGA RTX-2070 card I took forum a working Intel board. I put it on the AsRock board. The computer won't boot to the Bios screen. I had change the memory from 16gb to 32gb at the same time. Play around with the memory. I went back to 16gb of memory. The computer booted fine into windows.

But the computer acting funny. Mouse was freezing up and things didn't seam right. I put back the Gigabyte card and everything was fine. Put the EVGA card back into the intel computer everything was fine. Swap around the cards again and the same thing happen. The board just doesn't like the EVGA card.

There are times things just don't match up.

Hi dmdilks and thanks for the answer.

1st let me update that today I got the mobo replacement. Now it's the same Aorus Elite V2 but rev1.2 (I had rev 1.1)
Plugged the card but...again 4 beeps. This is the 3rd Aorus Elite V2 that this GPU card doesn't like to cooperate.

I understand your story but in my case I had a Sapphire AMD Radeon RX6700 10GB Pulse on my Gigabyte Aorus Elite V2 from 1 and a half year now and working perfectly fine. Store exchanged it with a new one after the fan got burned and....now it does not work....the same GPU card!

[dmdilks]

I understand what your saying. Did the store try another sapphire card to see if it is the card. The same card as yours? RX-6700. If it isn't working on 3 different MB then the issue is the card. I think what you said the card work on they MB's but not yours or your friends.

Of course the store did not have another Sapphire RX 6700 Pulse to test and why should they. 6700 seems to be stopped producing as I found almost no stock in any shop.
But If they had it will work good probably. Do not forget that my initial card was a same model sapphire rx6700 pulse again and after using it for 1,5 year the fan got burned they replaced it with that buggy one.

Yesterday I went again to the store and returned the GPU with the excuse that it does not work specifically on any Gigabyte Aorus Elite V2 B550, hopefully to force them test on that motherboard. Before that I asked the guy to do a testing and put the card to a "recent" system. He had a system with an ASUS mobo and an Intel i5-115XX. The GPU booted flawlessly to this system (so another motherboard to count).
The check was to see in CPU-Z if the card is identified as x16 or x8 on a "working system". Of course the test passed successfully.

The card seems to work on any MB except that specific Gigabyte model. I didn't have any other Gigabyte MOBO to test if this is a generic problem with all Gigabytes.
