This is the BIOS backup of my graphics card HD7670. This is a graphics card with 1G video memory. Can you help me modify my BIOS to 1G video memory?

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.

Your best bet is to figure out the exact model of the card and see if there's an existing unmodified VBIOS you can flash it with. If that's not possible, then and only then consider editing.

最好的办法是找出该卡的确切型号,并查看是否有现有的未修改的 VBIOS 可以用来刷新它。如果这是不可能的,那么只有在那时才考虑编辑。

I'm sorry, my friend. Thank you for your answer. I have used the CH341 programmer to flash many BIOSes, but the problem cannot be solved. Flashing other BIOS will cause the graphics card to fail to start normally. So I can only pray to modify my backup BIOS editor to solve my video memory capacity.This is a HD7670M graphics card
