I am looking to upgrade the RAM in our Cisco ASA5510 to 1 GB, up from 256MB. The Cisco part number for this RAM is ASA5510-MEM-1GB=. When I Google this part number, I get a huge variation in prices from various or even the same re-sellers (Amazon for example), ranging from 60$ to 250$.
Prior to asking here, I have asked Cisco and they simply provided that part number. So my question is, is the RAM in the ASA like any other contemporary RAM of its time? IE you can go with different vendors or OEMs as long as its the same specs or part number, or does it need to be a specific Cisco branded RAM or particular "Cisco tested/certified" brand of RAM? Is the RAM ECC RAM?
