Its because you are using a ROM designed for 8 GB cards on a 4 GB card.
If you look at the "SpeicherGrose" - Memory - it is 4096 MB not the 8000ish for the 8 GB card.

Did anyone manage to flash an RX480 Custom Card? When trying to flash my Sapphire RX480 Nitro+ I always get "Adapter not found" (when using ATIFlash) or "no ATI GPU detected" (when using WinATIFlash):
Radeon driver shows the correct card, hashing is also possible with default driver/settings.

which driver version your using now?
can you share your image at other web service, imgurl? i can't see your screenshoot.
i think the custome card using other rom, not same as reeffference.
I am using the most current driver from AMD Website. I am aware that custom cards needs another one, I already created a few and wanted to test them now.
But since atiwinflash (and even atiflash) do not detect the GPUs I can not test it

I need a help!
After getting unstable work with flashed card I flashed it back to original BIOS
The card is disappeared after rebooting
I still can see it in atiflash and I actually flashed it again with LowEnergy.rom
But - why I cannot flash it to original rom?

guys,
how can I know what catalyst driver version is running/use?
I open the driver properties.
but there is no information about the driver I installed.
I installed 15.12 and 16.9.1
I just found the date, not the version.
regards,

regards,
you can ceck the radeon system, at radeon system setting you will find more information about your driver and device.
are you using wattman to overclock your gpu ?

Can I apply this BIOS mod to Non Referance card?
You can
But it will not work

Word of caution when doing all of this.
When I first loaded my brand new xfx 480s into my PC, GPU-Z said BOTH card had a 97% ASIC quality value.
I have NEVER been able to get the flashing ROM to work on my win 7, countless flashes and reflashes and redoing drivers etc etc. Lots of crashes and resetting wattman and recovering drivers etc.
Low and behold, my ASIC quality on both cards is now 76%... So not saying this had anything to do with it.... but 97% ASIC brand new to 76% today with dicking with all this shit.

Follow these steps
1: (while everything is at stock, so stock rom, stock driver) i execute this command first (as admin)
2: I reboot to safe mode(Hold Shift while clicking reboot) and i replace that atikmdag.sys file.
3: I reboot back into windows with that replaced atikmdag file. Windows should load perfectly, same for your drivers.
4: I flash my rom (command line atiflash, also as admin)
5: I reboot with signature checks disabled (also holding left shift while hitting the reboot button), you can do this in the next screen after you clicked reboot while holding left shift. You'll get a menu and you just do this. (same applies for Safe mode)
6: Everything should look perfectly fine when rebooted (i do not get the "test mode" message in the lower right corner. It just works
)

This works in win 7? If not, how do I do it in win7?
Thanks.

Guys - in case you will get some results with custom cards, please share with us
My Saphire Nitro rx 480 8Gb is on its way - so I would like to try to play with it too

Hello,
I want to tune my Sapphire RX 480 Nitro+ (4GB) GPUs. I started by only inserting 1 GPU and already downloaded the BIOS.
I opened it in Polaris BIOS Editor which looks like this:
So, any advice which parameters need to be changed? I assume I could raise memory from 1750 to 1800 for example. What about the GPU (and mV in both cases)?
I would be happy if there is a site/thread discussing this.
Thank you!

I would download one of the tuned rom's posted and open it up and take a look at it. I think you will notice the differences and can start to tune your own bios from there. That is how I tuned my rx470's, and currently trying to do the same with custom rx480 cards.
So far little has been posted on the custom cards so it is completely trial and error on the custom cards bios settings.

My thoughts on Oc the mem is that there is no temp sensor on the memory. Gpu can show 50c as well as vrm but none of these cards have temps of the memory. Could it be that overclocking the mem could cause them to burn up since we have no clue what temp it's running? Just a thought
