To make memory upgrade do the following:
- DO NOT DO THIS UNLESS YOU HAVE GOOD SOLDER SKILS!
YOU CAN DESTROY PCB PADS AND BRICK YOU DEVICE!
TRAIN ON BROKEN HARDWARE FIRST!
- Find a PC3200 DDR 512MB PC memory with 8 TSOP-66 chips on it (Each chip has 64MB size and 8M x 4bank x 16bit memory organization) or 256 SODIMM with 4 memory chips. You should use only 4bank x 16bit memory chips! You are lucky if you got 16M x 4bank x 16bit (128MB) chip - use it! (NOTE: You typically need to match the manufacturer of the memory chips, with the exception of cross-branded chips, for example Hynix/Winbond, as used in this article)
- Desolder all chips using rose alloy
- Desolder chip from DIR-615 pcb and solder new one. Here is the list of operations:
- There is no need for software changes. Original u-boot detects memory size automaticaly. Just double check your soldering for shorts and other defects before powering up device.
- This is the result:
