    Plug2k,

    Alright, I have returned from testing the revised BIOS you provided me with in the post above last night. I did the same sorts of testing as in my previous post. Everything seemed fine except for playing actual games.

    With all settings at stock on the above BIOS you provided games would launch but immediately crash. Feeling that voltage was the culprit here I opened MSI AB and began increasing the Core Voltage by small amounts until I got all games to run stable for at least 30mins+ of gameplay.

    In the end I had to add +56(mV) to the core to get my cards stable on this BIOS at 1050/1250. The above BIOS you provided sets the card to 1.281(mV) max and my cards require 1.328(mV) to be stable at the 1050/1250 clocks leaving the powerlimit untouched as you said.

    After completing the initial round of stability testing with the voltage ONLY, I went back into MSI AB and set the Power Limit to +50% and set the Core Voltage back to stock. Games booted but took slightly longer to crash than with the Power Limit at +0%. Although no matter what I tried, leaving the Power Limit at +50% did not allow me to get the card stable at a lower Core Voltage.

    So in the end yet another BIOS revision is needed. I will be happy to test it as well!

    TL;DR: The Latest BIOS revision you made for me is unstable at stock voltage of 1.281(mV). The stock voltage on the BIOS needs to be at least 1.328(mV) and it probably wouldn't hurt to bump up the Power Limit a bit more either.

    Thanks So Much!

    Very strange, that your card would require so high a voltage to get stable @1050 core.

    1.35v is really way to high for it, but you asked for it, just make sure you check and keep a eye on your temps when using this bios

    as its set for 1.3v-1.35v depending on droop.
    and when you get back in to windows, make sure you reset back to defaults with msi afterburner, then test and dont use msi afterburner.

    for recording your gpu voltage and temps using GPUZ.

    *note, really though this is quite a high voltage for default reference clock speeds, im currently using around that voltage for 1180 core lol
    also power limit has been topped up, you shouldnt need to use powerlimit in msi at all.

    Plug2k,

    I completely agree that this amount of Voltage is very high for a measly clock of 1050/1250 Mhz. I mean 1050 Mhz is only 103 Mhz higher than the R9 290 stock clock of 947 Mhz and the memory clock remains the same. I guess my cards really are lemons... Regardless though, I will flash this new BIOS and then reset MSI AB to defaults and not change any values.

    I am not so worried about temps though as having both of my cards cooled by AIO water-coolers helps keep the temps down quite low. And I always keep GPU-Z running in the background to monitor all of the sensors on both cards.

    I will report back on my findings with this newest BIOS later tonight. I believe that at 1.3-1.35(mV) this BIOS should now be classified as an custom water-cooling / AIO only BIOS as the temps could get out of hand on air-cooling.

    Thanks Again!

    Yeah if anyone downloads that bios or you give it to anyone, *state ONLY FOR PEOPLE ON WATERCOOLING, i hold no responsibility if anyone burns out there card on default fan stock cooling.

    Okay... another try. :infinity:

    I am currently using BIOS version 015.042.000.000.003747 (from MSI) on my Sapphire reference R9 290.
    techpowerup.com/vgabios/149574/msi-r9290-4096-131205.html

    I guess it's the latest BIOS for reference R9 290 with UEFI GOP.

    What do I have to change for:
    1050 MHz GPU clock
    +50mV
    +50% power limit

    Thanks in advance! :)

    Plug2k,

    Agreed. If I pass out this particular version of the BIOS to anyone it will be duly noted that it is ONLY for use on water-cooled cards. But anyone who is flashing a modified BIOS to their GPUs should understand the risks. If they don't they shouldn't be flashing the BIOS in the first place.

    Regardless, I think it would be very interesting to see someone who has an R9 290 with a full-coverage waterblock use this latest BIOS revision and see how far they can go. :wanker:

    Thanks!

    I don't know what I did wrong, I changed these values and flash it always BSOD at Windows startup, anyone knows why?

    Its obvious. 1: your card might not be stable @891mv stock
    or 2: you edited wrong,

    ignore the voltage table, leave all those on defaults.

    only change the other 2 you circled and also change the 4 in the limit tables tab.

    then try again.

    you need to follow these instructions.
    disable msi afterburner from starting with windows after you have pressed the optimal defaults button
    then reboot system and flash that bios on your card.
    then go into windows and open GPUz then open sensor tab, then keep it open and record what the default idle voltage, then run a game and record what the cards max voltage is then post the link and i will do you a custom based on what leakage voltage your card runs on.

    Plug2k,

    Alright I have returned from a long night of testing. I have come to the conclusion (after testing every single revision) that none of the modified R9 390X roms that you (or anyone else) has created for me are stable while gaming. So, at this point I think it is back to the drawing board to make the "most compatible" R9 390X rom for the R9 290/290X. I have included an image of what I have done so far below:

    [​IMG]

    It seems that the past R9 390X bioses that were made cause instabilities with the R9 290/290X due to the way the Voltage and GPU Frequency tables are spaced out. By substituting the GPU Frequency and Voltage tables of an R9 290 BIOS that I know is compatible with my card into the R9 390X BIOS I have been successful in creating a modded R9 390X BIOS that (so far) seems very stable on my card. I will continue to refine it as I learn more about the BIOS Editor though and will eventually release it out to everyone!

    Thanks Again!

    -Insan1tyOne :)

    Any hope for MSI Lightning 290X?

    I have a couple of them and would like to test a 390X modded bios but i know there is no bios donor for it and the Samsung memory problem...

    My Club3D R9 290 RoyalAce also has the same Samsung ram on it. I got lucky, as the chance of getting a 290 non X card with Samsung ram on it was extremely rare. Sad to say, but we are out of luck. I seriously doubt any 390X will ever be released with Samsung ram on it.

    this 390X BIOS can use in every reference card. it's base on reference card PCB.

    Research this BIOS can fix 290X reference card Black screen problem and reference card Voltage problem.

    Hey, thanks for your guidance, though it's not what i've planned but it worked. :banana:

    I originally want to increase my min voltage to 1000mV(968mV default) and then set an offset of ~-90mV because with original BIOS my card can run at 906mV stock, but i get black screen after logon window with offset of >-75mV.

    Now i've settled with -69mV and the card works great.
    Is there any side effect in doing this btw?

    [​IMG]
    Now i don't need to use stinkin' cmd parameter for moar voltage. :banana: :banana:

    It's stable at voltages a lot lower than 0.891mV. I just tested what you say and now it worked! Thanks a bunch :)

    Only thing is to take VRAM_Info table from 290X bios and add to 390X rom, I have not done this nor do I know if it will work.

    I know nothing more about roms than what we all have been discovering sharing, I'm planning this weekend to look at VRAM_Info table HEX values to see what can be deciphered.

    As we have no manual for the roms it's basically educated guess work.

    I don't think the offset present in a rom has anything to do with ASIC quality.

    1) I've found them more often in factory OC'd card roms, this is so the card function at the upped speeds without an issue.

    2) I also believe they use it as a fix to blackscreen, on Sapphire forum some members have reported their card black screen they contact support and they receive a updated rom with higher voltage offset and their problem solved.

    There are also possibly other reasons as well.

    I'm glad you were able to solve your problem :) , sorry for late reply. I have been adding all info what we as a group have learnt in a thread on OCN , I will also do one Guru3d soon as well. That way people don't need to piece together info from different posts

    No worries :) , as long as card is stable at lower volts I can't envisage a side effect.

    In this post is SVI 2 complaint voltages

    The Stilt stated when a non SVI 2 voltage is used the voltage controller will use the next closet match, in your case 0.89375v .

    Instructions in linked post how to use the voltages shown , also he stated it can caused stability issues but OneB1t has entered/tested non SVI 2 voltages and they function without an issue AFAIK.

    I personally stick to using the SVI 2 voltages.

    Barrier broken, 0.847-0.850mv idle voltage.
    this is no longer this low with msi afterburner, this is without any software at all, basiclly bios defaults.

    i couldnt get under 0.900mv before now @0.850mv :D
    its finding the correct voltage is the key, some voltages will not let you and will show up as 1.019v in windows if the voltage is not compatible.

    i have overcome that ;)

    yeah,m8 some are not compatible, even when using the voltage ic2 table
    some work some dont. lol

    The good news about this is i also did some testing under UEFI mode in windows when using SECUREBOOT> msi stops working
    and no overclocking tools work to let you control voltage, only thing that works is changing clocks and memory.

    but using this method, bios editing works in UEFI your voltages stick and your clocks stick and when finding the perfect bios you can overcome the issue of not using any overclocking software at all, and best of all UEFI works..

    next on my tweak list, is UDV video playback.
    when watching bluray movies the card uses to much voltage and clocks go way to high so i want to reduce those also to get way better playback and lower temps.

    mate can you list what the states are again
    so i know what to tweak, what state does what ect.... i know you listed them somewhere in this thread but im to lazy to search lol
