[w0lf0.]

Hello guys, i have big problem with my card, after mod bios with 1500 straps to all up only one motherboard of mine detect the card, also after restore the original bios the problem remain and i don't know how possible can be it  

-Asus crosshair V formula Z >>> detect it with mod bios and with original bios
-Asrock h81m btc >>  no detect it with original bios and modded bios
-Asrock Z97 Anniversary >>> same h81m btc, no detect it with original or modded bios

What is the problem guys, how possible one motherboard of 3 detect it? I never see one problem like it

If you are using Windows you need to patch the driver signature check when using a custom bios. Uninstall the drivers using DDU in safe mode:

Then reboot, reinstall the drivers and use the pixel patcher to patch the driver before rebooting:

To see if it's an issue with the motherboard, install the card in the primary PCI-E slot with a monitor or dummy plug attached and see if the card is detected. It could also be related to the PCI-E settings in the motherboard bios.

The probem isn't windows driver i think because motherboard doesn't detect the card, the only motheboard that detect it is asus crosshair v formula z but with no riser, if i connect with riser i have no signal on monitor.
this card was modded with 1500 straps but now i restore original bios but also with original my motherboards doesn't detect it

What depend that gpu isnt't detectable by motherboard if connected with riser and is ok if connected directly? the riser is ok i tested with other gpus

Thanks for help spiz0r, i cant't understand if it is a sort of brick, only the asus detect the card and only if connected to pcie, asrock z97 anniversary and asrock h81m btc doesn't detect it and how possible the problem remain also after i restore the original bios backup of 470

You are right, it is really strange if it works in at least one motherboard.
Just to make it clear, if you put it in any other motherboard, it doesn't even start, right? You just have a black screen.

Atiflash

Then you can try to flash the card using bios from techpowerup database. Open it with bios editor and check the values. If the size is 256kb open it with atiwinflash then save.

Load it in atiwinflash then save and check if the size is changed to 512. Better don't flash with this 256kb only.

You can flash it at your own risk or leave it as it is. I'm not responsible for the consequences.
