Just got 2 RX470 Strix and would like to undervolt them. 

For some reason i can not go below 0.981v and voltage only drops when downclocking.

So eg 1050mhz@ 0.981v if i set 1075 goes to 1.031v. Am I using WattTool wrong?

I've found that the RX 580 is more than happy to accept RX 480 BIOS. However, AMD still detects the card as an RX 580, in fact the pre-580 drivers do not see the card at all. Further, you can not force RX 480 drivers onto a 580 card which has 480 BIOS. This seems like a dead end.

And what happens when you flash a 480 to 580. Does it it get detected as a 580?

Later I'll create a tool to reverse the process if possible (from decoded timings to strap).
Hmm My AV find it a thread:

Not a stupid question, anyway I tried searching this topic for an answer but google was faster. People who flashed their 480 to 580 report gpu-z and afterburner seeing the cards as legitimate 580 cards... SO what's the problem other way around, it's strange why the 580 with 480 bios hardware id's would be detected as 580 still... Are you changing the id's correctly or leaving the 580 id's?

when I flash 580 bios with atiflash, yes I can see Polaris20 in the cmd windows then opening TRIXX my 480card is now seen as 580 since I am not editing the ID whatsoever

I submitted a bug report to AMD as follows, if others can do the same it'd be appreciated:

This problem applies to catalyst drivers starting from the RX580 Press Release drivers and is still current as of 17.4.4.

The new drivers which support the RX 580 now cause a BSOD with message "ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY" when attempting to use greater than 5 GPUs. This was not the case prior to the RX 580 Press Release drivers.

The testbed is a Z270-A Pro motherboard with a Celeron processor, 8GB RAM, 1800W PSU, using Sapphire Nitro+ RX 580 Limited Edition graphics cards. This configuration works for RX 480 graphics cards using sub-17.3.x drivers with 6 GPUs under Windows 10. Further, the same system supports 7 GPUs under Ubuntu using amdgpu-pro drivers.

Isolating the problem consisted of having 5 working GPUs and attempting to add the 6th. On boot, BSOD noexecute error. Unplugging ANY of the existing cards alleviates this BSOD on boot. Further, once 5 GPUs are active, you can disable one of the GPUs and install the 6th GPU without error as seen in the attached screenshot. The moment you select to re-enable the disabled card, again BSOD noexecute error, seemingly confirming its a driver issue. The choice of disabled card is arbitrary, it works with any one of the cards disabled. The hardware works as confirmed by booting into Ubuntu and all GPUs are operational.
