    • This guide is applicable only for NVIDIA GTX470-780ti graphics cards, including GTX Titan 6GB and GTX750Ti (Maxwell1 architecture)

    • The method can be useful only for visual artifacts or "Code 43" symptoms (see pictures)

  2. Fix visual artifacts/code 43 for NVIDIA GTX470-780 by programmatically disabling bad parts, Preparations: шаг 2, изображение 1 из 1
    • Disconnect power plugs from the PC, unplug the problematic GPU. Connect plugs back and boot with display attached to motherboard's video output - this is needed to enable special boot mode windows option for easily entering "Safe Mode" to prevent boot problems on Step 3

    • Get .ZIP with the "OLD Nvidia Artifacts" utility, unpack it

    • Run the utility, press "Enable boot without driver" button

    • Note the displayed instruction on entering safe mode during boot - it will be useful during next steps if the PC will hang due to problematic GPU

    • Shutdown your system normally, disconnect power plugs, and reattach the problematic GPU

  3. Fix visual artifacts/code 43 for NVIDIA GTX470-780 by programmatically disabling bad parts, Flash VBIOS several times: шаг 3, изображение 1 из 1
    • 1. Perform a first VBIOS flash: select the problematic GPU and press "Flash testing VBIOS" near it.

    • After flashing is done, press "Reboot"

    • 2. Run the software again. If the graphics driver starts up fine, press the "Activate more blocks and reboot" button at the bottom. Otherwise, press the "Flash fixing VBIOS and reboot" button. The software will try another VBIOS variant

    • 3. 4. 5. Rerun the tool after rebooting up to 3 times to let the utility select the best VBIOS

  4. Fix visual artifacts/code 43 for NVIDIA GTX470-780 by programmatically disabling bad parts, Finalizing: шаг 4, изображение 1 из 1
    • After a successful modification, a pair of memory chips are disabled. Fixed GPU works fine in any computer

    • If the utility fails to fix the GPU, use the "Rollback to original VBIOS" button
