              That's the only option to disable ram and it works. Either you are doing it wrong/understanding it wrong and/or you have another problem. Please specify what resistance combination you have shifted.

                      Good evening, would it be possible to show or say which resistors need to be removed?

                                      Page 12 of schematic has the table for disabling onboard ram.

                                      Both schematic and boardview is available on this forum.

                                      However, if you still can make it out, specify the ram markings on your motherboard.

                                                  by mat2k
                                                  Hello, I've been googling for some pointers on this but couldn't find anything that applies to this board. I have an Acer A315-22 (board NB8607) with faulty RAM between 142 and 174mb. I just wanted to disable the onboard RAM altogether, but this one doesn't seem to have any memory down ID resistors or strap in order to disable it. I'm attaching the schematic I found, the boardview for it also seems to be available somewhere in this forum but I still don't have a use for it lol.
                                                  How would I disable the RAM on this PC? Thanks for the help.

                                                  Hello.
                                                  I have an Acer Aspire A317-53 laptop with faulty onboard ram modules, after online searches, I have only found two options to get it working :
                                                  - first one is to modify le bios to disable the onboard ram.
                                                  - second one is to disable the onboard ram by desoldering some components on the mainboard.

                                                  so after some hours google-ing, i have to give-up the modified bios option, main reason is I couldn't find anywhere a such modified Bios, alternate reason is that if windows update makes a bios update, the problem is always here...
