    i think you can edit 295X same way as 290X or 390X :) bios reader can load all 6 tables for 295X

    @gupsberg: yes i can force to change all 6 values at same time :) also can limit them to say 1350 or something :)

    green values are just calculated voltages for specific ROM as they not responding to any changes :)

    Setting fixed voltage in place of voltage pointer will disable EVV for the given DPM state.

    The "voltage table" in Hawaii Bios Reader can be removed from the software, the values are just used as a reference by the display driver (they hold no functionality).

    Yes, PM link to your bios. Will only edit and upload once I done tests on my card :) .

    Agreed, lower it to a tad further, as you know the reader is already out there in the wild, we up if necessary after testing. I will update OCN thread stating caution on this.

    Thanks :thumbup: .

    I didn't download and view your bios yet.

    I was looking at the new released roms by The Stilt and what we see in MSI AB dump is relevant to reduce offset if your bios has 8d 00 xx 00 in VoltageObjectInfo table.

    In his -25mv offset rom there is FC in the magical offset hex values.

    Or better yet we do the fixed voltage mod! (thanks to clarfication from the man himself ;) )

    there you go guys, R9295x2 bios.

    My edited UEFI version and RTL untouched Bios
    so that you can add unified R9295x2 bios support to all R9295x2`s. ;)

    Extended question : why doesnt R390x bios`s work on R9295x2.
    i think the issue is the display method.
    R9295x2`s have 4 mini dp ports
    and 390x`s have 1 mini display port, is there anywhere in a bios that can detect what output port your using and change those output ports to mini dp only, that way i think would make 390x bios`s display output on those cards.

    probably a long shot though something else for you guys to figure out lol if its actually even possible.

    or if there is not a way is there any way to change the hardwares vendor/ id so that graphics drivers think you have 390x cards and install drivers and give your cards the name R390x :)

    Is this a serious question? :)

    295X2 cards have master and slave configuration.
    Both of the GPUs have their PCI-E lines connected to the PLX PCI-E switch, which splits the single x16 PCI-E link in two.

    290 or 390 cards obviously don´t have such chip as they are single GPU cards.

    Also the VRM controller and configuration is completely different on 290/390 and 295X2 cards.

    Flashing 390 bios on 290 card won´t make any difference.
    The driver path decision is made by the driver based on the fused "Revision ID" of the GPU. 290 cards have RevID 0x00 while 390 cards have RevID 0x80, despite the DeviceID being identical.

    No matter which bios you flash on the card it won´t change the RevisionID. It is fused.

    If you want to have the most recent driver optimizations made for 390 series exclusively (if there even is any) you need to edit the driver inf.

    390 cards are identical to 290 cards from every aspect other than higher clocks and different driver path.

    Is your link wrong? post 8 user has Stilts new gaming rom.

    IIRC HardOCP review had a section where they down clocked a 390x to 290x speeds and clock for clock the same.

    ***edit ***

    Brain fart, reread and I got wrong end of stick! LOL

    Read this in another post by you was gonna add quote here but had others things on mind ;) .

    Many reviews I read and viewed PCB images are not the current designs 390x 6+1 vrm and 290x 5+1 (ref design/layout)?

    we tested 290X vs 390X on our czech forum and there is some small boosts in 3dmark score (like 200 points on same clocks) i know that cards are same except that fuse and different clocks (and some bios modifications)

    next 200 points was from driver 15.15 so it was around 7% graphic score increase vs 290X + older 15.1040 driver on same clocks

    dunno how its now on 15.7 WHQL if 390X still have driver advantage or not

    EDIT: just flashed one of your modified bioses and it looks like its on par with 390X in 3dmark :) also very nice VRM temperatures (i have gelid icy vision v2 + modified reference cooler plate for VRM cooling

    Must be the tighter memory timings at work.

    IIRC 390X has tighter timings, again from what Stilt said in another post! ;) .

    He's done VRM work on bios.

    The GPU is identical.
    ODMs change their PCB design from time to time anyway (revisions).

    Wasn't really serious just wishful thinking lol,
    i just wondered if it was possible to edit a r295x2 bios and add the 390x name into it so that drivers would detect the card as R390x and install drivers and keep name R390x :) there for keeping the data all the same... so when you went to install none modified amd drivers it would detect the card as 2x 390x cards in your system :D

    but its probably to hard to do that and as you said the id would be different and fused so no point in trying that out lol

    anyway im just looking for voltage changing on my card up to 1.400v as this card is fully watercooled with water block :D


    -----------------------------------------

    Also guys could you add an advanced setting tab on the hawaii editor and remove all but the voltages that are needed to make it more simplified for people

    for instance

    put names for

    UVD voltage
    3D Voltage
    2D Voltage
    3d clocks
    2d clocks
    UVD clocks

    you get the idea just keep it simple as the program is beginning to look a lot complicated and for people that dont know what there doing could damage stuff.

    its interesting to see 7+2 phases as its probably still controled by IR3567B or there is some new controller?

    @Plug2k: you can change codepath for driver its explained in some thread here on guru3d i try to search and send it to you :)

    also 1.4V is kind like 800W under load from for R9 295X
    i dont really want to keep it that simple as this still request some knowledge its better when its complicated so people need to search on forums for such changes

    sweet ;)

    let me know guys when the hawaii bios editor has full 295x2 added so i can test it out as i think your adding compatibility for voltage changing and i will let you know if it works :D

    well using msi afterburner the max i can get out of the voltage is 100mv+
    ranges around 1.320-1.340v

    that nets me around 1180mz / 1690
    if i had 1.4v i know i would be able to hit the magic 1200mhz/1690

    under load with those volages i net around 60c in temps and thats perfectly normal considering the default cooler nets around 75c then throttles the card to protect it from damage ect

    so even if you added 1.4v the card would not damage it would just throttle once the temps hit 75c, these cards have in built thermal protection if you dont got the cooling the card would still be safe.... but if you have the cooling and can keep the card under 70c then its perfectly safe. even like i said going up to 1.4v would still be safe...

    you can add to 1.4V by console command in afterburner but i dont think its wise decision :D

    not really worth to get 20mhz for such power consumption increase its not linear in this range
    you can create pretty expensive brick even with watercooling

    hehe i will leave it to you to add the highest voltage you think is safe then and i will test out and let you know if i require more hahah :D

    problem is that afterburner offset is on top of voltage in DPM7 so i can cap it to 1.4V but if you start PC with +100mV offset in afterburner the core gets 1.5V which is not nice

    i will add that warning into software so everyone know to reset their offset before flashing new bios
    i also found that C# datagrid is kind of pain to work with so it may take a while to implement these limits

    np mate take your time :)
    in no rush, make it as safe as possible :D
