Bought this specifically for a low cost alternative for the ASA 8.3 minimum upgrade requirements of 512MB RAM on a Cisco 5505. Worked on the first try. Yes, ASA 8.3 will load and run with 256MB, but it displays a warning on the CLI and ASDM that not all advanced features will work. Well, for under $30 you can sidestep the issue. I did try with a 512MB DDR Unbuffered ECC stick with no joy. The 5505 just displays a red light and seems to absolutely require non-ECC (the cheap stuff ;)) RAM. This unit installs flawlessly with no modification to the shell/cage even though it is a little taller than the original 5505 256MB RAM chip. Also, I believe (have read, but did not try) that you can put a 1GB UB non-ECC DDR stick in the 5505, but it will only recognize the first 512MB.
Update 2/27/2011: Tried 2nd RAM upgrade in another Cisco ASA5505 and after the unit heats up and you try to reboot, all lights on the device start to blink and it never boots. Let it cool down and it works again. Bottom line: The ASA5505 seems to be VERY particular about the RAM used in it. I have two more of the same RAM upgrades on order. I'll test and update this review after I receive them. I guess it's possible I just received a bad stick of RAM.
About the packaging, the modules were loose in the cardboard box and both had a slip of paper taped to the gold contacts. I carefully pulled the scotch tape off and cleaned the residue off the contacts and it worked. I would have expected a simple anti static bag, but nope.
I shut my computer off, opened it up. It fit right into my computers mother board and after turning everything back on, the improvement was immediately noticeable.
I would like to make clear though that this is common on the ASA's and the RAM works as stated and if its the right type of memory that you need then dont hesitate to buy this but would avoid it only if you are going to put it in an ASA.

Used this memory to upgrade a Cisco ASA from 256mb to 512mb. No issues. I had tried another brand to go to 1gb but that did not work out and I had to return it. Read morePublished 23 months ago by Andrew LaPorte
