Polaris Bios Editing ( RX5xx / RX4xx ) - Page 60

post #591 of 3350
Anyone have an Asus strix RX470 rom?
I cant find origin Asus ROM another ram Hynix frown.gif

No need for bios modding any more, this one still works:
http://www.overclock.net/t/1387430/amd-how-to-change-the-power-control-limit-from-20-to-50
AB 4.3.0 Beta14 extends Vram limit to 2600MHz; u can also use Afterburner settings, "Extend official oc limits".

to raise the PT change this value:


if there is any trouble, try edit MSIAfterburner.cfg:
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1

Strange. Eliovp/Heliox claims that the hex mod for VDCCI (8E) works for his RX 480.

Could You look at his post w/ the proof screen here:

Guys, did anyone here had the luck to have 8gb physical memory with 4gb cards, with non-reference cards?

@cez4r

No idea on what is going on redface.gif .

The Stilt stated output loop 2 is not used in ref PCB RX 480 when the whole powergate thing was going on. Therefore using register 8E shouldn't have an effect. Due to it not being used when The Stilt released ROMs for RX 480 powergate issue his ROMs only had VMAX for loop 1 and not 2, his Hawaii ROMs always had VMAX for both loops as they were both used.

Perhaps as Eliovp/Heliox is using a Nitro something differs on it. I am not experienced or knowledgeable enough to comment from viewing say a high res Nitro PCB image to say what is connected which way in this case.

Without a voltage control chip that has a data interface adjusting a voltage via ROM/SW would have no effect. For example there is VDDCI value in Fiji PowerPlay but it has no negative or positive effect on card's operation when adjusted, as there is no programmable voltage control chip for VDDCI voltage on PCB.

To know whats going on when an owner is adjusting what is labeled in Wattman as memory voltage we need information where someone has taken a voltage reading using a digital multimeter say for VDDCI, has anyone posted this information?

I no way refute the posts where members have stated when they change memory voltage in Wattman it has an effect on what RAM clock they can achieve/sustain, but this is not clear proof it is VDDCI or MVDD IMO. Perhaps Polaris has SMC like Fiji and the GPU on-die controller is adjusting a voltage explaining why members see an effect, I don't know redface.gif .

If MSI AB is now supporting voltage control on Polaris it would be interesting to see the MSI AB info screen, this would also confirm if Polaris is using i2c or SMC messaging for that tool IMO.

On Hawaii/Grenada cards when you click the "i" in MSI AB window you would see a screenie like this:-

The MSI 290X Lightning had IR3567B & IR3570B, when you click the "i" in MSI AB window you would see a screenie like this:-

Warning: Spoiler! (Click to show)


On Fiji you would see this :-

Warning: Spoiler! (Click to show)


From what I understand/tested on Fiji, MSI AB,etc message SMC via driver, then SMC sends command to IR3567B, and I then see the register for voltage offset change in i2c dump. As SMC is always keeping i2c line between it's self and IR3567B busy, i2c dump takes a lot longer than Hawaii using MSI AB (so far AIDA64 lacks support for this on Fiji). Even though Unwinder gave some pointers on SMC messaging on Guru3D/OCN I found no info on HBM voltage adjustment SMC message command (ie output loop 2). MSI AB not only supports i2c operations via command line but also SMC messaging, there is a post on Guru3D by Unwinder (author of MSI AB).

Thanks, very informative!

Edit: From what I've heard the latest version of MSI AB doesn't support all Polaris cards - MSI's and Ref's only.
So I cannot check it...

No worries smile.gif , when you do an i2c dump via MSI AB on your Polaris card does it takes ages? it was pretty much instant on Hawaii as no SMC stuff going on. Here is a video link on me doing i2c dump on Fiji via MSI AB, I initiate dump at 0:33 and ~2.52 it will finish redface.gif .

Here's the MSI afterburner information screen for a MSI RX 480 Gaming X 8GB :

The reference 480s and at least the reference style sapphire 470 have NO memory CHIP voltage control. They are fixed voltage at 1.6v for the samsung chips. What wattamn calls memory voltage is misleading, since that is the memory INTERFACE voltage on the actual GPU. Its the memory controller on the actual GPU die, and thats what this value adjusts (also known as VDDCI).

You can directly check all these voltage on the back of the PCB. The capacitor banks in the center show core voltage, and some of the capacitors on the edge of the GPU area show VDDCI. Just be careful when probing since you can easily fry your GPU if you short something.
