I am upgrading a half dozen 3640's to 128MB RAM. From my searching, it appears the 3640 requires 60ns, Parity or NON-parity, 72pin EDO memory. Looking at Cisco web-site not clear on this.
I have installed some IBM 72pin, 70ns, Gold-lead, Parity memory in all four SIMM slots in my 3640. It boots up fine, in 64 bit, Parity mode! Am I at risk of damaging my router?
Another router booted fine using IBM 72pin, 60ns, Parity, Gold-lead EDO memory from an old IBM Aptiva computer. Again, is this a potential problem? Thanks so much for advice. Would hate to meltdown my new-found test lab!!!
