No, it's not stupid question. Your request is not an easy task. Before your request can be answered, research need to be done first. What type of memory did you use? Did you use PC2-6400 (DDR2-800)? AFAIK, BIOS doesn't responsible in limiting the total amount of RAM you can use (I didn't found any proof to say otherwise). Hardware does. What I know is, each of the memory slot have maximum supported capacity. If the maximum capacity is 1024MB DDR2 & it only have two slot, it means total amount of supported memory is 2048MB DDR2. Who is responsible to this limit? I 'd blame the memory controller. I found the AMD Athlon 64 X2 Dual-Core processors specification page in 3rd party website. It said 4GB is supported if you use 4 x 1 Gbyte double-sided PC2-6400 memory module. Unfortunately, your notebook only have 2 memory slot.
If you use my modified BIOS image & you like it, please consider making a donation. Thank you very much.
