AMD/ATI ATIFlash - flashing questions

[SoNic67]

I want to edit my RX580 Device ID with the ID of a WX7100.
In the help of DOS version of atiflash, I see the following:

-mi <Num> [ID]          Modify SSID & SVID in BIOS image of adapter <Num> to
                        <ID>.  SSID & SVID in BIOS image of adapter <Num> is
                        displayed if [ID] is not specified.
-mb <Num> <File>        Modify SSID, SVID, BIOS Pin Number, & Boot Message in
                        BIOS image of adapter <Num> to values in <filename>.
                        Input file example:
                           ssid = 715B
                           svid = 1002
                           biospn = "113-xxxxxx-xx"
                           bootmsg = "AMD graphic board"

-isr <Num> <Build Number> <Board Number>  Set ISR number based on the given
                                          build and board number
                                          if not specified, print out ISR Number
-prod <Num> <12 digit serial number>      Set PROD number based
                                          on the given serial number
                                          if not specified, print out SN Number
-checkprodsn <Num> <12 Digit Serial Number>  Comparing the Prod SN based on
                                             existing prod sn saved in ROM

Firstly, I guess that the SSID is not the DeviceID? How do I change that?
Secondly, can someone explain what's up with the ISR number?

Check the 580 bios against a WX7100

I know people who've flashed RX 480 VBIOS to the mobile WX7100 so it should be compatible?

 

[eidairaman1]

This is the only bios i found here

Where did your reference bios for a wx7100 come from?

 

[SoNic67]

That's the same BIOS and, based on the ID numbers cross-checked against RadronPro ccc2_install.xml file, it seems that is a laptop version. If I had a desktop version, it wold be nice.

What I did until now (and didn't work) - I have hex edited the ID numbers in my stock BIOS (there are two BIOS portions, one legacy, one UEFI). During the search in the BIOS, my ID appeared in three places (reversed endian). I calculated and applied the new checksum. I even edited the name (RX580 is in clear).

After boot, Windows and gpu-z are still showing the card as RX580. So that's somewhere else.
I know that nvidia added also hardware straps for ID's (resistors soldered on the back) on Maxwell (or newer) cards: https://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/
Wonder if AMD did the same for their Radeon RX5xx gen cards?

PS: I had as backup card an older ATI HD 8450 (Caicos, TerraScale 2) gen card in a secondary slot, to be able to recover-flash if anything went wrong.
Works well with generic MS drivers, in combo with CGN and AMD drivers, but if you try to add AMD TerraScale 2 drivers with the GCN ones it will mess up your Windows! I have to recover the drive, and even after that the profile was corrupted, had to delete it from registry.

Yeah that's the only bios we have here unfortunately

I want to edit my RX580 Device ID with the ID of a WX7100

doesn't the WX 7100 need use/access to ECC ram ? I'm sure I read some was trying to do same thing but was having stability issues, gave up and flashed it back to rx580 sure it was due to ASIC quality difference between the rx580 and WX 7100 and think they said something to do with ECC ram (not sure if they mean on card or in system) needed for some of the types of software critical app's the card was made for? not sure if any of that is correct though lol so just asking

 

[SoNic67]

No ECC on the WX7100, basically it's the same card like RX580, lower clocked:

hmm maybe they mean, recommend ECC ram for the system, to run certain apps for the drivers of the wx7100 ?, the long and short of it from what I could make out is the WX7100 is higher quality silicon and its higher clocked and more reliable.

I see if I can find were I was reading it

have a read on here may help figure something out

I may have to try that see if I can get a gpu installed on server2016 ,cheers , how are you both thinking its mobile though , it's top clock is 1243 and it looks clock for clock like it should for the wx7100 afaik.?

Im not thinking its mobile, thats the only 1 in our database

GDDR5 is ECC memory. Both cards have it.

And that ROM linked above is NOT for a WX 7100 Mobile. It has the device ID of the desktop version(1002 67C4). The device ID for the mobile version is 1002 67C0.

didn't know that ?

 

[MrGenius]

Technically it's EDC(Error Detection and Correction). Which is, essentially, synonymous with ECC(Error-Correcting Code). Both are just slightly different techniques used to achieve the same results.

Yeah I got to learn how to read device IDs a little bit better to expand my knowledge of it all because eventually I will be doing bios modifications myself

Download the AMD RadeonPro drivers and expand them with 7zip.
In the "Config" folder you will find the file "ccc2_install.xml". Open with an editor (notepad) and search for:
Device Id: 1002 67C4
Subsystem Id: 1002 0B0D
You won't find anything.

Search only for the 67C4. The devices with Device Id 1002 67C4 are either "Ellesmere Mobile GL XT" or, if they are, "Ellesmere Desktop GL XT" are marked as "AMD Radeon(TM) Pro Duo".

But search for the desktop WX 7100 Graphics and you will see they have only the Device ID: 1002 67C7 See the screen capture below.

PS: And no, EDC is not the same as ECC. EDC insures the data integrity on the chip (die) itself, while ECC is realized between chips, organized as a word, requiring an extra memory to hold the parity bit. Like instead of eight memory chips, you have nine soldered on board. Plus a separate controller to calculate the parity.
