Memory Upgrade for Cisco ASA5505

As many know, upgrading an ASA5505 to run firmware 8.4 causes older generat= ion 5505s to exhaust most or all of the default 256MB of configured memory.

For those who, like me, don't want to spend $200 for a $20 DIMM here's what= you need to know: Cisco has limited the silicon that can be used to only = Infineon/Qimonda chips. They coded only these parts in the memory table of= the custom Linux kernel employed by their firmware. If you buy a 1G Kings= ton/Crucial/etc DIMM you might get lucky, but you might not. Neither of a = Kingston KVR400X64C3A/1G (Elpida chips) or Crucial CT12864Z40B (Micron) wor= ked in our ASA though others have apparently had success with the Kingston = part at times. An Infineon HYS64D128320HU-5-B (about $20) is the ticket an= d will definitely work since it will always have Infineon chips. Qimonda w= as purchased by Infineon awhile ago; the original 256MB DIMM in the ASA has= Qimonda-labeled devices.

Posting here to help others avoid my experience of buying three DIMMS in pu= rsuit of the upgrade. Still came out cheaper then buying the 1G Cisco SKU.
