If the crashes happen without the RAM expansion then I'd suggest a closer look at the CPU and Agnus sockets. Contact cleaner, check for contacts which are broken or have lost their springyness and clean any tarnished pins on the ICs with a fibre glass pencil.

I'd do that before looking closer at the memory data buffers etc.

BTW to avoid removing and reinserting the Gary adapter multiple times (which won't do the Gary socket any favours) while you do tests you can bypass it and leave it installed.
Simply use 2 jumpers & link pin 5&6 and 7&8 on the Gary adapter 8 pin connector.
