HD7670M graphics card backup BIOS/4G, this is the BIOS I backed up, but this is a fake graphics card, the memory chips are GDDR5, Hynix H5GQ1H24MFR=128M, there are 8 chips in total, the total is only 1Gb. Playing games sometimes results in a black screen, but the sound is still there. I want to learn programming to change the video memory to 1Gb, but I can't find the relevant tutorial. Can you help me modify my BIOS to 1G video memory? Many thanks.
