Hi everyone, this question is for Gordan: I have a GTX690, and I'd like to mod this card to add more ram. In my research I discovered that this card uses the Samsung K4G20325FD-FC03 256MB BGA memory module, the GTX690 has 16 bga modules in total (8 by each GPU), that means 2GB per GPU. I want to replace those modules to this Samsung K4G41325FC-HC03 with 512mb bga module. I checked both and they have the same specs, except the memory density, so I think it'll be fine for compatibility reasons. I have enough experience soldering BGA modules, so it will be easy.The downside is that someone told me that I have to mod the bios to address the new modules size. I know you mod your GTX680 4GB bios to 2GB, what I'll do is in reverse, modding my vbios from 2GB to 4GB. I know the script block that you mentioned in this forum before, and I have checked the vbios from other brands. All of them have the same init memory block, my question is: I have to patch the full block on my GTX690 bios? or just only the five hex keys that changed when you patched the bios?. I'm telling you this, because the other brands bios have more differences, allmost 10 hex keys to change in this block. Thanks in advance!!
