I would like to share this with the folks here as well as with AMD and all of the Manufacturers that use AMD Processors & chipsets. This is a common problem that is becoming worse and worse. Even though many of the peoples from Eastern and Mid-Eastern countries have what they feel is a good understanding of English, we are seeing that all too often certain items are being mislabeled and have nothing to do with what the instructions or manuals say that they do. Point in case here for AMD might be, on the RX 580 Vid cards there is a tiny switch and often goes unnoticed. On one companies card, it is said to do one thing and on another companies card, it is said to do something completely different. AND in my case, it does none of the above. I was having problems getting the card to cooperate with UEFI and thought what could it hurt, so I flipped the switch and low-n-behold I have a UEFI capable VId Card. NO ONE at any of the manufacturers had any clue what I was talking about or how to fix it as most of the people I was talking to had a reasonable grasp of the English language and like myself expected the switch to control what the Manual said it did. In other words, it wasn't the CS agent's fault, but the person who wrote the manuals and instructions. It's not just AMD either. I see this with Samsung, WD, M$, and many other companies. Users would have a lot better chance of figuring this stuff out if we had the correct information.
This may apply if you purchase a AMD hardware directly from AMD and was manufactured by AMD but AMD really has no control over what AIBs or OEM Manufacturers write in their manuals or instructions for the their Customers.
Since AIB or OEM manufacturers are the ones that built their customized AMD hardware using AMD Chips they are the ones that write the manuals and instructions for their Customers.
Best thing to do is let the AIB or OEM Manufacturer know that their manual or instructions needs to be more transparent and better written.
It applies to EVERYONE who does not have adequate Quality Control over their manufacturing, design, and documentation. Unless you can prov that you have NEVER done this it would apply to you. I would have to look up your particular card on this issue that I used as an example but even that was JUST AN EXAMPLE! By the way, befire I retired I was a Quality Auditor certifying manufacturers for ISO Certs.
Sir you do realize this is a User to User forum and I am just a User.
If you opened this thread just to get User's attention here at the Forums about how manufacturers sometimes create subpar documentation or products or poor QA Inspections then so be it.
Yes that would affect everyone who purchases a product from a Manufacturer. But the options I know for Users to let the Manufacturers know of their displeasure is either through bad reviews, complaints to the Manufacturer directly or through a Government agency, or Using Forums if applicable, etc.
But coming here and saying that AMD is responsible for AIB or OEM subpar documentation isn't correct.
You mentioned that Switch on the RX 580 GPU card, was it sold directly or manufactured by AMD or was it a AIB or OEM GPU Card. IF it was a AIB or OEM GPU card, like I mentioned, AMD has no control over their documentation concerning their GPU card. IF it was sold by AMD directly or manufactured by them then you can always open a AMD Service Request (Official AMD Support) and let them be aware of their incomplete or subpar manual or instructions on that specific product.
I have purchased, in the past, other Consumer products that had, in my opinion, subpar instructions or manuals. Normally if I write a review I would mention that in the review.
To me, personally, my highest priority is whatever I purchase is complete and works correctly and doesn't become defective within a year's time. So basically the quality of the product is good and reliable for the money I spent on it. But then again that is why manufacturer's have Warranties.
Now if I purchased a prescription medicine with poor documentation and I got sick or injured following the poor documentation, than that is something that needs to be looked into either legally or through a Government agency, as an example.
Unless I misread your original post then other Users here at AMD Forums can give you their inputs about AMD or AIBS or OEM subpar manufacturing process, Quality of their products, QA inspections, or documentations.
If you're seeing a small switch on a graphics card, it's almost always going to be a BIOS selector switch. You haven't said where you got this RX 580, or even what brand it is, but what you describe could easily be possible if one BIOS was UEFI compatible and one wasn't.
No documentation would reflect this, because the change in functionality from one switch position to the other would be the result of the BIOS software in use, not the switch itself.
