1  Alternate cryptocurrencies / Mining (Altcoins) / Re: RX480 (Reference) 31+Mh, Custom Rom on: August 14, 2016, 05:34:49 PM
Greetings forum members Smiley ,

I had no hand in creating the patched atikmdag.sys , it is all Lordkag of Fernando's Win-Raid forum work Wink .

My only contribution is contacting Lordkag for another issue I needed help solving with Fiji custom ROM and asking if he knew of a fix to allow custom ROM usage on Polaris.

IIRC and what I understand, he has highlighted the permanent solution would entail driver/patch being signed and no need to disable driver signing in OS to use the patch. I have no ETA on when this would occur.

I would kindly & respectfully ask members using the Lordkag patched atikmdag.sys to make a donation on Fernando's Win RAID forum as way of thanks & appreciation for the help.

Here is link to Polaris bios editor, there are threads on OCN, Reddit, etc by author/users with interest in bios mod. Now we can use it thanks to Lordkag patch on driver Smiley and AFAIK the patch is for atikmdag.sys for Windows 10 driver.

All the best
Gup

The question is still there. Is it possible to mod memory voltage (not core or aux voltage) on Hawaii via bios editing?

Memory voltage (ie MVDDC) can not changed by bios modification.

IR3567B on Hawaii / Grenada controls VDDC (core) / VDDCI (aux) only.

Only cards which allow software manipulation of MVDDC "out of the box" are Asus 290X Matrix and MSI 290X Lightning, which I don't think most would buy here given the context of use on this forum. So far I have not seen any R9 300 series cards with MVDDC "out of the box".

MVDDC can only be changed with "hard vmod", google the terms 290x mods - kingpincooling.com 1st hit is correct link, in 1st post 1st link is document showing "hard vmod". In this post by The Stilt you'll see it may yield you only small power usage drop.

Hello there, I followed the instructions of the op to undervolt my Gigabyte r9 390, but when I read the voltage values in the gpu freq table here is what I got :

0   0xA49D   300   Mhz   24-bit   0xA4A0   900
1   0xA4A2   525   Mhz   24-bit   0xA4A5   65282
2   0xA4A7   723   Mhz   24-bit   0xA4AA   65283
3   0xA4AC   883   Mhz   24-bit   0xA4AF   65284
4   0xA4B1   924   Mhz   24-bit   0xA4B4   65285
5   0xA4B6   960   Mhz   24-bit   0xA4B9   65286
6   0xA4BB   994   Mhz   24-bit   0xA4BE   65287
7   0xA4C0   1025   Mhz   24-bit   0xA4C3   65288


As you can see, excepting state 0, the other state voltages are not what I was waiting for.

Do you think it's safe to try values comparable to the values of the op ?

Simply put:-

In all stock ROMs only DPM 0 is manually set VID, so in your example you see 900 (DEC) and unit is mV.

DPM 1 - 7 in all stock ROMs is "auto calculated" VID, the numbers 6528x represents that, the last digit is basically ID of DPM.

Also note in ROM we are setting VID , what we see in software monitoring is VDDC. VID is what the GPU is set to, VDDC is realtime voltage, this will variate due to PowerTune tech / LoadLine Calibration.

All good mate  Grin , I lurk here on and off and hadn't been here in a while. Then when I saw this and didn't recognise user name I thought I'd been hacked  Grin.

Yup, Eliovp = personal for when i'm at home (or on my phone)
Ldw-com is when i'm at work/warehouse Smiley

Cool Smiley , I thought somehow I'd been hacked  Huh as I was reading 2 members posting things that only 1 could know  Grin , then I thought perhaps their friends. So I thought I gotta register and ask  Smiley .

Expect your inbox to get flooded now that there is someone else to contact Cheesy

Hmmm, I'll just have to not reply  Tongue. Been off and on lurking here, mainly to read things the Stilt has posted TBH.

Couldn't have done it without you Smiley. Wouldn't even know where to start if it wasn't for you Smiley

No worries  Smiley , I also appreciated your participation.

So Eliovp = ldw-com?



Check the op, Changed the "someone" part to Gupsterg now that you're here Smiley

No worries Smiley .

i change it by adding the vddc and mvddc offset in the rom, this because it's standard not there.

Same goes for Fiji, VDDC and MVDDC offset are not standard in the rom, i had to add those myself.

Hmmm .... seems like I wasn't the first to create/release these ROMs?  Wink .

However, Due to adding those bytes:-

- you need to correct table length for VoltageObjectInfo.
- the pointer within VoltageObjectInfo to i2c programming data would need updating as well.
- you also then need to remove the same amount of empty bytes to make UEFI/GOP at right offset location.
- directory of data/command tables would need updating in ROM to correct offset pointers to the tables as they would have shifted.

WOW, I'm thinking these are my words  Wink .
