    Yosuru got a reaction from Hairless Monkey Boy in GPU Identity Crisis (Is that an RX 550? No it's an RX 460. IT'S AN RX 560D?! But it's a POLARIS11)   
    Found a vBIOS from a random thread of unlocking RX560D shaders from 896 to 1024.
    A random person uploaded their Yeston RX560D 4GB GDDR5 Micron memory to be unlocked.
    I tried that vBIOS and it causes system hang whenever the driver is installed without needing to use ATIKMDAG patcher.
    Something else must be wrong with this card but at least we now know that it is in fact a "Yeston RX560D-4G D5 TA".
     
    Thanks to 191x7 for the very swift identification of the card. I don't know how long it would take me to identify this card without his help.
     
    With that said, this thread is done. Thanks ya'll.

    Got this graphics card from a bargain bundle.

    For $20 I got:
    - AOC 16" monitor, USB Powered, VGA Only. (No Issues)
    - 2.5" 500GB HDD (No Issues 100% Health)
    - "RX 550 2GB" (Untested)
    For the price, I couldn't really complain if I got a defective GPU.
    I plugged it into my PC and BAM!, no POST. I quickly put my GTX 1060 6GB back and plugged the "RX 550 2GB" into a riser card and it booted into Windows just fine.
    I opened Device Manager and there I see it "Microsoft Basic Display Adapter", then I opened GPUz and there I see it. (pardon me for not taking screenshots around this time)
    GPUz sees it as an RX 560 4GB card, wow that's sus. That's very not what the seller said it was.
     
    Oh before I forget, I should show what the GPU looks like. It has no label anywhere, the appearance of which does not associate it with any of the known GPU vendors except... POWERCOLOR but not quite.
    *The GPU was pretty much never been opened when I got it, the sticker on the screw was intact.

    Here's what a Powercolor RX 550 looks like:

    It's similar but not really. Does anyone recognize the logo at the fan hub?
     
    So anyways I thought it was just an incorrectly flashed VBIOS in the card, GPUz shows the card as an RX 560 4GB and the core frequency default is 1076MHz and Memory Clock default is 1500MHz.
    Although the current reading both reports 0MHz.  (pardon me for still not taking screenshots around this time)
    It also bugged me that the shader unit count was 896 instead of 1024. A bit of searching led me to believe what I got on hand is an RX 560D. A chinese variant of RX560 with only 896 Shaders.
    I used GPUz to save its VBIOS as is when I got it and the filename was defaulted to Baffin.rom.
    1 [VBIOS IT CAME WITH].rom
     
    From a bit of research I discovered that Baffin is of POLARIS 11? But how can that be for an RX500 series graphics card?
    So I tried getting my hands on a VBIOS but I had no way of confirming its memory type.
    So I decided to open it, and there it is Micron memory (GYZY 8NA47 D9TCB). Tried searching to no avail which was odd.
    From here I also took the opportunity to verify the GPU from its DIE number (216-0896088) but my search led me knowhere except for one thread.
     
    https://forums.macrumors.com/threads/2011-imac-graphics-card-upgrade.1596614/page-392
    on post number "9793"
    KennyW stated that "216-0896088 is RX460 (likely rebranded RX560D)" and a lot more insight as to how confusing the RX 460s and RX 560s was during the time.
     
    I was already very confused at this point so I just tried flashing an RX 560D VBIOS with Micron memory support.
    ATIFLASH detected the GPU as an "ATI RADEON POLARIS11" which just adds to the confusion because the detected VBIOS (the VBIOS it came with) was of an RX 560 POLARIS21 4GB as seen in the pic.
    *How reliable is AtiFlash in identifying GPUs? Because GPUz relies on the card's VBIOS in identifying cards right?
     

     
    Pardon me for this was the only screenshot I could find.
     
    I did not go through with that flash just yet though.
     
    The very first FLASH I did I tried force flashing an RX 460 4GB into it.
    2 [VBIOS I first flashed].rom
    GPUz saw the memory value of 4GB just fine but the core and memory were still 0MHz.
    I tried installing an AMD driver and it detected the "RX 460 4GB" and it installed. But the GPUz still shows 0MHz so something must be wrong.
    Device Manager reports Code 43 on the card and so I immediately suspected that the VBIOS I flashed wasn't just quite it.
     
    So I did try to force flash it to an RX 560D Sapphire but then it failed and bricked the card.
    Sapphire.RX560D.4096.170929.rom <It was this but I deleted the one I edited with Polaris Bios Editor (just changed the vendorIDs and deviceIDs so I could flash it)
     
    After almost an entire day of attempting to unbrick it (Error reading ROM & Adapter Info Not Found), there it was IT JUST FLASHED AGAIN.

     

    ^Trying to undo the damage, the FLASH suddenly working actually failed again but at least it remained flashable so I flashed the last known flashable ROM into it.
     
    I was able to reflash it back to the RX 460 VBIOS I tried just before that and I have not touched it ever since.
    3 [VBIOS It has right now].rom
     
    Can anyone help identifying this card? I really want to be careful this time into the VBIOSes I try to flash onto this card.
     
    GPU: AMD 216-0896088
    Memory Chips: GYZY 8NA47 D9TCB
     
    Forgive me if the post is a bit confusing, ask me anything if it helps.

    Yosuru got a reaction from Haro in RAM ECC Registered/Unregistered, Buffered/Unbuffered??? Help   
    Alright that clears things.
     
    Yes
     
    Having a bit of headroom also helps for multi tasking and video rendering.
     
     
    Alright I think I get it now, Registered = Buffered and Unregistered = Un-buffered. and Buffered will never work on Un-buffered Motherboards
     
    Thanks.

    Try to set your Power Options (Control Panel) to High Performance
     
    and/or underclock the GPU a little
