The leading 04 indicates it is a memory test failure. It is my understanding that the subsequent digits are a bitmask identifying which chips are bad. Typically you see just one bit set, so would hit something like 048000 for the chip located at G12 on the logic board. If you've got multiple chips bad, each bad chip sets a bit in the error code, so 0488DC would be chips G12, G8, F12, F11, F9, F8, and F7.

That's almost half the RAM chips, so I'm going to suspect it's not actually the RAM that's bad, but something else causing the RAM test to report the RAM as bad, like the power power from the analog board or something. So caps might be a good place to start.
