I'm using 800mV with a voltage offset of -68.75 in WattTool.
Flash videos are a very good stability test for 2D.

Doesnt seem to work. Vid is still 800mV. U should double check with gpu-z.

***Update

Had to Lower the voltage and Mhz from 2200 Mhz / 1150 to 2150 / 1100 and it's working now. Well at least run one becnhmark and 0 error's.. I suppose error's means instability? Shame that is getting less point's tongue.gif

And thank you for check that point.. I hould never see it, unless gave me some crash. Thank you once again smile.gif

Is there any one that did a bios flash on a asus strix rx 470 stock speed 1206/1650.

As now the value is differing from windows driver, so it may change it to D when booted into it. Therefore I would always power down and up before going into Mac OSX if you have booted into windows.

Here is increased bias ROM.

No experience of Mac OSX redface.gif . If in Mac OSX you have a SW tool that can read i2c information from IR3567B, we'd be able to confirm if the register that is setting VRM load balancing is being set as per ROM.

So it took me a good while to actually test the new aggressive setting. Sadly I think it is too aggressive now, not allowing for the card to boot. I suspect this because I could not make it work in Mac OSX. Also when I boot to Windows from a cold boot it will not go into acceleration mode. After I warm reboot from windows (when drivers have probably overridden the values) I am able to get it working again. This makes me suspect that it is indeed too aggressive.

I might have to take another approach, it might even mean that I will have to go back trying to edit the Mac OSX Kext files. Do you think you could supply me with the HEX values for the different power modes? Maybe I can start my search there trying to see if there are any of them present in the Kext already. Thanks for helping me out so well before!

Is the mV memory value bugged? I modded my bios to use 1150 mV (testing timings) when it hits 2000 Mhz but watttool shows 1000 mV (stock value).

UPDATE:

I tried some timings that weren't stable (few EDC errors) at 1000mV, no they are perfectly stable with 0 errorrs... It possible that the real value is 1150 but Watt Man and Watt Tool shows me 1000 mV just because it should be the default value? Can some one confirm/test this?

FULL STORY:
I'm modding the bios of my RX 480 Nitro+ OC, I'm quite unlucky (80% ASIC but I cant't OC s***) my VRAM can reach 2220 MHz but everything past 2100 just spawns EDC Errors (a ~5k at 2150, ~2kk at 2220, crash past 2220). I still have to touch Core frequency and voltage, I want to tweak my VRAM first. I decided to improve timings, at 2100 with the 1750 strap copied onto the 2000 strap i just need to raise the memory voltage to 1025 mV to be perfectly stable (if not I get like 10 errors, nothing to be worried about but I want to be safe). My current plan is to raise the voltage to 1150 mV (the max safe mem voltage) find the tightest stable timings (following this method: https://youtu.be/TR25v-jvWao , starting from 1750 timings as base) and later, find out if I can lower the voltage a bit (I hope 10/20 mV).

I modded my bios like this:
- TDP and Max Powerlimit = 225
- TDC = 190
- Copied 1750 timings to 2000 strap
- Set 1150 mV next to 2000 MHz memory frequency

I didn't change the frequency to 2100 and left it at stock 2000, so I'm sure that the card boot and I can set it manually by (when I find the best timings I'll set 2100 inside the bios).

Btw, the real question is, now the memory is perfectly stable but WattMan and WattTool still shows me 1000mV, since the m is stable should I assume that the 1150mV is correctly applied but the oc tools shows me 1000mV just because it should be the default value? Can someone try/confirm this thing? Is 1150 the max safe voltage for memory controller? Is 1.300v the max safe voltage for core (future plans)? My card is cooled by an Arctic Accelero Hybrid III 120 + Custom Unified VRAM+VRM+PCB Heatsink + Back Heatsink (pictures will come).

Does anyone know how to change the default voltage offset (the one that you find on WattTool)? I could even do with hex edit, I'd just like to properly know how xD (where to write the new values)

So I just got my reference rx 480, and out of the box, I throttled to 900mhz with heaven. Increase power limit, 1266 as expected. So I flashed the unlocked bios, same behavior. I manually opened it to 200w power limit and still same behavior. Anyone have any ideas because I am stumped after bricking it 3 times.

GPU Core power is reading 200ish watts in gpu-z and hwinfo so I'm really not sure what's up.

You need to increase TDP, TDC and max power limit.
