Frequently asked questions
Why upgrade memory in a Cisco router or ASA?
Newer software releases and larger routing tables need more DRAM than the base configuration. ASA software 8.3 and later, for example, raised the minimum memory on the 5505, 5510, 5520 and 5540.
Will a standard DDR2 module work in a Cisco device?
Sometimes. Several Cisco parts are standard modules, but the form factor, voltage and ECC requirements have to match exactly, and Cisco supports only its own qualified parts.
