I tried setting Acoustic & Sensitivity limit to value 0... Fan still hasn't come on... but now since I added this to the back side of the VRM... fan seems never to come on... Off all the time... VRM feels cool to the touch now... Amazing how thin a piece of copper goes so far in cooling. Impeccable thermal performance with copper... I used 3M adhesive on both sides of Fujipoly pad 2.5mm thickness probably too thick but all I had to prevent shorting through the pad with pointy ends sticking out... Does very well. Still wish I could keep the fan at 20% minimum... go to 40% at 60C and so on... It stays off pretty much continuous now... kinda wanna get the VRM down to ambient haha with a bit of fan speed... I may do this on the Core of the RX 460 to knock 10C off the core temp, Among doing it on my 390X Core/ VRM... kinda wanna make one huge copper plate to cool the entire PCB though on my RX 460 and 390X... will do the same when if I ever receive a Vega or RX480 biggrin.gif ... Keep those tiny transistors/ capacitors and what not cooler... Copper transfers heat so fast and cools off really fast too... Just putting your finger on it... within seconds reaches the temp of your finger... remove finger.. within seconds back to ambient.

Code:
usFanOutputSensitivity; /* Sensitivity of fan reaction to temepature changes */

Higher value = more sensitive/reactive to temperature changes the Advanced fan mode/Fuzzy Logic mode will be.
Code:
ulMinFanSCLKAcousticLimit; /* Minimum Fan Controller SCLK Frequency Acoustic Limit. */

Try an SCLK same as DPM 0 of GPU, IIRC 300MHz on RX 480?

Does on Polaris WattMan allow a zero setting for AL?

So I changed the hex value under the PP_PhmSoftPowerPlayTable in the registry to extend the power limit of my RX-470 to 100% and oddly enough my voltage which is 1.15v prior went up to 1.22v. Is that suppose to happen?
post #1235 of 3413
Hello everyone,

How can I edit the voltage of the memory on RX 470 in bios? In watttool it works in a weird way, as in, it works like a secondary voltage to the core, and I cannot set the core below 1000mv, if I don't set memory voltage under 1000mv too, but I don't think it affects memory in any way (running on 0.8v at memory, same oc results achieved on memory).

Also, editing the voltage tables for the gpu core in Polaris editor doesn't do anything, I tried changing 65288 with 65287, 86, 85... or specific values (like 950) for P7 and it doesn't work, same voltage as with 65288.

Thanks!

The stupid thing with multimon using a lot of power at idle is due to that issue of vcore can't be lower than vmem in wattman. So anytime the memory goes to full speed, it makes that (1.0v stock or whatever you set) as vcore.

Like the mem controller locks onto the same signaling voltage. So amd, can't you make an intermediate memory speed for multi mon, like 800 mhz and use less vmem?? You got 7 freaking states for core clock/vcore, but only 2 memory states? Dumb

This is true for the mod BIOS does not is impossible to use a driver?
post #1238 of 3413
Greetings to the whole community, I recently joined this forum.
I write from Italy and I know not English (Google Translate) for which I apologize to everyone.
I own the video card XFX Black Edition RX 480 GTR and I wanted to thank you for all the valuable information that allowed me to understand and change the BIOS of this board.
I was able to enter commands to the registers of IR3567B controller:
1E 1F to set the Load Balancing to FFF000, (58% - 42% is correct?),
38 to control Load Line Calibration,
8D to set a voltage offset for the Loop 1.
Obviously I also modified the other necessary parameters and my bios working properly.
Instead escapes my understanding the value to be applied to 3D registry to set Vmax only for Loop 1 to 1.36875 volts (AMD vids = 5?).
I tried with the value 15 (1 = Loop; 5 = AMD vids) but the AIDA64 dump gives me the FF value then the value 15 has no effect.
I apologize for my lack of knowledge and are very grateful to anyone who can help me.
Thank you.

Having same problem. What do I have to change with HxD to make it stick?

I've had luck with having bios settings stick and not get overritten by installing the AMD drivers alone, and none of the fluff. Any OC / tweaks through AB. It's been about a month, but I remember seeing the voltage was where I set it, at 960mv.
