    Blackscreen issue on R290/R290x is mostly a low voltage GPU when switching from 2d to 3d or changin pstate. To resolve this issue you can lower RAM frequencies or pur +25mv on your GPU.

    It could be useful to edit video BIOS on r290 but actual tool like vbe doesn't work. I found that some skilled overclocker has edited BIOS to supporto more voltage for ln2 overclock or to mining... I tried to edit via hex editor but VGA refuse to start windows (BIOS digitally signed?).

    Any idea?

    Unfortunately there is no tool to edit the new bioses and keep the digital signature.

    The reasons why this happens could be numerous reason is driver issues, inefficient power supply, etc. So Im not sure that editing the BIOS of the card will help.

    95% of user with black screen resolve raising voltage with +25mv... Check the web

    There is obviously a way to edit the fan profile, clocks and voltages without losing the digital signature.

    I don't have 10 posts, so links cant put embedded. :(

    techpowerup. com/forums/threads/new-bios-update-available-for-asus-r9290-dc2oc-4gd5-not-double-post-for-reference-r9.198516/page-2#post-3132558

    litecointalk.org/index. php?topic=12830.msg121827#msg121827

    Now anyone have any luck finding out how they are doing it? Must just be in a hex editor??

    In the end to fix my issue, I went with the Gigabyte GV-R929OC-4GD F21 Hynix Mem bios and its been rock ROCK solid for my testing over the last few hours. Not giving the black screens that the Tri X OC default bios did.

    Tri X OC Bios - 1000 / 1300
    GV-R929OC-4GD - 1040 / 1250

    So the mem freq is slightly lower but I think the gigabyte bios has some voltage change too. Now I can run 2560x1440 @ 120hz without any issues.

    i have an asus 290x dc2, can't use other bios because my card has a custom pcb... so the only way it's to edit the bios

    I have already posted about fix for this blackscreen death. Simply lower the ram speed. With my amd 290 sapphire-vaporx I only needed to lower from 1400ram speed to 1375 and have not had any issues since. There is no need to raise voltage or mess with bios etc. Just use the ccc with the driver... enough said.

    yelsewshane is not a fix "lower ram speed" because i have random black screen in linux too. Sometimes artifacts loading pc out of windows and sometimes systems boot up but screen remains black.

    raising voltage give me an assurance that my card will work with every S.O. and out the s.o. environment

    my cards works perfectly at 1100/1500 with +50mv on the ram so isn't a bad card... only too much conservative voltage applied from default by amd/asus with elpida memory.

    It maybe a fix on some cards but not on others this is where your fix comes in.

    not my fix...

    http://www.overclock.net/t/1441349/290-290x-black-screen-poll

    many other thread like this on the web.... many users fixed black screen with little overvolting...

    the problem isn't if this fix works for everyone (+90% of users with black screen it works), the problem it's editing bios.
