Hello, been awhile since I lasted posted on this site. Yes, I been using the Max Unleashed bios for my gtx 970's. I have some 970's laying around. One I had for awhile, that one had the bios already flashed, Then I tried to flash the Max Unleashed bios that I had on to this other gigabyte gtx 970 with NVIDIA NVFlash, Certificate Checks Bypassed v5.287. This is the one I used to flash the other card, all went well, BUT, the other card I tried to flash now has a black screen. The monitor picks ups the gpu but screen goes black. I put the card in the second pci-e slot and used gpu-z and here what it says: On the good working one, everything comes up except for like fillrate,bus width and bandwidth, this is showing up like this because I recently un-installed the drivers BUT the 2nd gpu, this bios, memory size and the shader says Unknown, the other gpu don't have this problem. Also, I tried using this card as the main card and tried to start system, on my mobo, it says code 62 and it just stays there unless I push power off. Under nvflash I tried to install the graphic drivers while this card is on the 2nd pci-e slot and its a no go, system reset itself. Upon further inspection, while on nvflash, I did --list, both gpu's says geforce gtx 970. While still under nvflash, I tried flashing again with NVIDIA NVFlash, Certificate Checks Bypassed v5.287, and I get an error: Command id:1000000E command: NV_Ucode_CMD_Command_W Failed Command Status:NV_Ucode_CMD_STS_NEW Error: NV_UCODE_ERR_CODE_CMD_VBIOS_VERIFY_BIOS_SIG_FAIL Command id:000E Command: NV_UCODE_CMD_COMMAND_W FAILED Command Status:NV_UCODE_CMD_STS_NONE Error: NV_UCODE_ERR_CODE_CMD_VBIOS_VERIFY_BIOS_SIG_FAIL Then it tries to store updated firmware image, everything seems to go through after the failed attempt. I also Looked under device manager while no drivers are installed, there is 2 microsoft basic display adapter, the good working one has no exclamation mark on it but the one that has problem has an exclamation mark on it. The card however was working perfectly under stock bios. I also did further inspection of the card, taking the heatsink off to see any pcb damages, there was no burn resistors, caps,etc, I even took the backplate off, all looks good, no unusual smell or anything. Most interesting of all is this, the gpu, while feeling the heat with your hand, it seems it barely seems to get warm at all, while on the good working gpu, you can feel the heat kicking in and more pronounced. I think the card still works but it seems I can't flash it at all. I also tried to use the latest nvflash and see if I can revert it back to stock, it manages to flash with no visible errors and yet I still get black screen and mobo hangs at code 62. If anyone could help, many thanks.
