Memory Upgrade

Post by cybertronics »

I would like to try to upgrade the ram in this tablet. I currently have 4 chips ( Hynix 526AA HY5DU121622BT-J ). This totals 512mb.  :)

Does anyone know how to go about this? I am familier with this type of solder rework and am willing to give this a try if anyone can help me out with how to implement this upgrade. I dont believe that it is as simple as soldering more chips on top of the others, allough I could be wrong. :o

Part numbers of chips and where to order would be a big help. also any advice is welcome. ;D

Thanks
