    Help needed : Original bios / Club3D 6950 Coolstream

    This Bios also can make the card boot : http://www.techpowerup.com/vgabios/94169/powercolor-hd6950-2048-110121.html But no more luck with drivers even after reinstalling them. Edit : not stable cause 880 MHz OC made card crash and force reboot in game, used oldest one (hamilton) and was fine.

    Help needed : Original bios / Club3D 6950 Coolstream

    It was a short term happiness : can't manage to get drivers working. Seems that catalyst / atiadlxx.dll can't recognize the card as a valid amd card. Device manager says that driver is not compatible with this device :/ At windows start, warning on atiadlxx.dll that can't start (incompatible...

    Help needed : Original bios / Club3D 6950 Coolstream

    I just tried on another computer : no display, since switched on. I don't have any bios "beep" either for troubleshooting (should hear 1 long and 2 shorts for VGA default, which is the case if the card lacks 1 PCI-E). Keyboard stays "interactive" so computer does not seem to hang, just...

    Help needed : Original bios / Club3D 6950 Coolstream

    I already flashed both BIOSes as it won't boot on both. I 'll have a test on another computer I have at home to validate that the GPU is the issue. This 6950 is getting closer to the bin I think

    Help needed : Original bios / Club3D 6950 Coolstream

    I switched back to GPU (PCI Express) as primary in MB BIOS and moved HDMI cable to GPU. At boot, I have no display at all (no BIOS displayed). Previous vBios was not the first one to make it unbootable. The first one was one with 6970 shaders activated (I don't have exact reference here)...

    Thanks for taking some of your time to answer me since beginning. Additionnally, I did not mention that the card still doesn't boot (i am on IGP). That's the point that afraid me most.

    0. ATIMan uninstaller : Went OK on automatic and extreme mode after reboot. BUT warned about a missing VGA driver, and prompt to install a driver before rebooting (don't know were log is stored for a copy). I had no clue of what was that, and a forum search showed most guys rebooting and...

    Help needed : Original bios / Club3D 6950 Coolstream

    Thanks a lot. For position 2, I forgot to set it back after a recovery reboot and trying another flashing. I guess I've done some wrong things, including not removing AMD drivers while trying these flashes. What made me think i am in a bad situation is that I already flashed _1.rom to...

    Help needed : Original bios / Club3D 6950 Coolstream

    Hello, I bought this graphic card, club 3D 6950 Coolstream, which was booting correctly. I tried to unlock 6970 shaders, and cannot put my hands back on original BIOS. I think I messed up things with AtiWinFlash, including bios 2. I already tried switch 1 & 2 for bios, and also tried...
