Cisco Router 3640 Series Upgrade
Memory Configuration
A system upgrade is recommended if you are working with several memory-intensive programs at the same time. At least 1 or 2GB of memory should be installed.
Important information about your system memory (RAM)
Your system supports only memory modules with selected memory chips. If you think you have found a store for a lower price elsewhere, then it is possible that the cheaper memory chip will not work.
or you get your money back!
