Dopy25 Posted August 28, 2022 Share Posted August 28, 2022 I posted about this in the ST section but hoping someone in the hardware section might know something. I am trying to upgrade the RAM in my 520ST. I removed the old chips and in doing so used too much heat on one area of the board. It caused a couple of the ceramic caps to burn up BUT all of the traces are fine. The caps seem to not be needed because they don't even come into contact with the new board but I could be wrong. The new ram is an upgrade by agranlund, fixed by a user and posted here on AA. I've double checked the traces on the RAM board, and the main board on the ST. Nothing *seems* out of place. There are no bridged traces on the RAM but I did accidentally bridge a couple once. Could I have blown something on the board by accidentally bridging say the vcc pin on any of the ram chips? Or would it only burn the ram? I goofed and didn't check if I had any bridging before trying 6 different chips on 3 different expansion boards. All have the same outcome. I do have 4 other chips I can try and will absolutely make sure no pins are bridged but honestly I'm curious to know if anyone may have a theory on this. All the expansion ram boards have the same outcome after I've checked no pins were bridged. Quote Link to comment Share on other sites More sharing options...
