D-Link DIR-615 C2 64MB memory mod

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!
  1. 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)
  2. Desolder all chips using rose alloy
  3. Desolder chip from DIR-615 pcb and solder new one. Here is the list of operations:
  • Tools and materials:

  • Rose alloy melted to lower melting point temperature:

    D-Link DIR-615C2 memory mod - rose alloy added

  • Old original 32MB chip desoldered:

  • PCB pads cleaned using soldering iron & cotton swab:

    D-Link DIR-615C2 memory mod - pcb pads cleaned up

  • New 64MB chip soldered (use a lot of good flux and clean it after soldering)

  • 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:
