Hawaii Bios Editing ( 290 / 290X / 295X2 / 390 / 390X ) - Page 319

post #3181 of 4008
My undervolt results for my 290 so far:

I previously used only a negative offset and was limited by the lower power levels getting unstable. I could go around some of it by setting the Vram frequency low for all except the highest power level, but still could not reach the lowest possible voltage for the highest power level.

So I now spend half a day testing out stable voltage for each power level by:
- Heating chip up with FurMark to around 65-70 °C
- Running occt with error checking alongside for min. 2 minutes.

I ended up with this:



I then added one voltage offset (=0.0075V) on top of what you see here as safety margin.

This values looks more impressive after voltage drop. wink.gif

I was worried that maybe I get issues when the chip drops from a high power level to a lower power level, and then the temperature are higher then in my test cases for the lower power states. But so far no issues.

I know i am the worst kind of post. I am trying to find a solution here and i have start reading from behind.
Is there a way for Undervolting Gigabyte G1 390 or i am loosing my time?

Here is my Def bios ? Giga390biosdef.zip 100k .zip file
post #3183 of 4008
Well...

The easy way to undervolt is to only change the voltage of the highest power level.

The link to the application, that would let you know what your actual voltage per power level is, is broken. (Voltage gets calculated from your GPUs leakage and some constant values)
Just edit your bios file and give the highest power level something like 1150V. Then patch your BIOS. If its unstable under workload just mod it to something higher e.g. 1200V.

Now get a GPU heavy application with error checking. For example OCCT.

After the application runs and your GPU is at 100% usage you can just play around with the voltage offset (Via one of the many GPU tools, e.g. Trixx) and slowly lower it until you get errors. Then go up again and test for some time until you find a setting that is stable. Maybe add one extra voltage offset (Smallest voltage step for hawaii is 0.0075 Volt) as margin.

Now just subtract that offset from your current bios voltage and mod the bios again. Done!

It is important that the GPU is at 100% all the time when testing like this or your PC will crash with to much negative offset voltage. Because the offset also changes the lower power levels voltage.
Don't worry this crash could not damage anything, but I would be kind of annoying to crash during testing. Also I found that sometimes the drivers just remember old voltage values after a restart. And if you got stuck with bad values your PC will instantly crash when starting Windows. Then you have to time consumingly remove the driver (DDU) and reinstall it. The same can happen with the GPU tools like Trixx, so just throw them out of the autostart if you have them there.

Wait you think i can just do that from HawaiiBiosReader? Or i need to do that from hex editor, that is a problem for me?
You know that Gigabyte 390 g1 has hard locked Voltage ?
post #3185 of 4008
Well HawaiiBiosReader is just a glorified hex editor for a limited range of values. wink.gif

But I did not know about the voltage locking on that card.

The live offset changing won't work then. But you still can try to change the power level voltage values in the bios file and see it if works. Testing different voltages just gets a bit time consuming in that case.

in SSVID and SSDID changing guide
what does 2h* mean? 2h*SSVID and 2h*SSDID

thanks


edit:
i think i got it
thanks for the guide, mihastar

Sorry for delay got busy with my own meddling with a FreeSync display I got recently redface.gif .

In the ROM pack is your supplied Sapphire 390 Nitro ROM modded to have fSW registers. 500kHz ROM = stock, but stock ROM did not have the registers, the memory feature of IR3567B was setting fSW, so think of this ROM as stock with editable fSW registers.

@kithylin

Glad to read all successful and working great for you biggrin.gif . That's nice 3DM score IMO, here's a compare with my VX290X 4GB 1150/1575 and I had 390 MC timings/RAM timings tightened, you have a clear 2% lead in GS score / GT1 & 2 FPS thumb.gif.

I have no issue with you adding me to your Steam account, but there is no need for you to buy me a game TBH smile.gif , the gesture is more than enough thanks thumb.gif .

I already have games on Battle.net / Origin / Steam / UPlay that I bought but never played. Would you believe I got Starcraft 2 Battlechest over a year ago on some lightning deal on Amazon and yet to play it, same with Evil Within, Alan Wake, PainKiller and so on biggrin.gif .

So the fsW is at stock for now and i can play with it? nice^^ You are awesome!

And with Freesync: i have a problem there too. in most games and benchmarks freesync is working fine but in the remasterd Bioshock it is not working at all... range is 40-75 and i set the max fps in radeon @ 74. with vsync and without tearing everywhere. Dying Light works perfekt

Well okay then. smile.gif

The only "Issues" I've had is I once had a issue where all the screens went black and then 2 came back but center one was "reddish" .. only happened once and it was on a day when I had problems with my A/C and couldn't get it working and it was 91 f Ambient. Even though listed card temps in gpu-z were like 67c vrm & 76c core.. I guess the hotter ambient temps must of done something "wonky" to the poor card because I've had no issues since then and keep my room around 72f - 76f now and it hasn't returned. Also I was playing Ark: Survival Evolved, an early access / unfinished game and that may of caused it too. I don't think it had anything to do with your bios mod, most likely just heat that one day.. so far (knock on wood) it's fine. I suspect I may be running on the extreme upper limits of air cooling with this overclock, even though core temps don't seem to be that high.

The ROM with 500kHz is stock fSW, but now editable in ROM, as it has the registers.

The other ROMs are below stock, no editing required, as fSW is set per kHz in title of ROM, but editable if you require.

Prior to flash make sure you have deleted MSI AB profile file, located in install dir /profiles. After flashing power down and up PC to make sure IR3567B is reintialised with new ROM info.

On MG279Q (stock FS Range 35-90Hz), FreeSync is working for me on Bioshock Remaster. TBH Bioshock you could run without FS as FPS is gonna be high/stable for even 144Hz V-Sync On IIRC from FRAP testing I did at 1440P, don't know what res your using.

I may mod the FS range on MG279Q using CRU, this is a util I'm talking about floating on web not the AMD CRU in driver.

@kithylin

Probably OC/room temp issue. You are at quite a high VDDC for OC IMO . Take your stock DPM7 VID and add 0.175V and that is your final VID on OC. Not on my PC currently so can't check data you gave, but IIRC your in the region of 1.4V+ on air. IIRC my VX290X 4GB used 1.325V VID to nail 1150MHz, I felt that was too high for air, even though GPU temp <75C VRM <65C. So I stuck with 1100/1525 @ 1.3V.
