    Well now, I had upgraded my Compact Flash Card on the ASA5505 Adaptive Security Appliance some time ago. This upgrade had been documented a while back on some forums, and of late I had found a new Cisco site: www.cisconews.co.uk who have documented this Compact FLASH Upgrade very well.

    I had upgraded from 128MB CF to a 256MB about 2 months ago, but when I seen a sale on in my the local toy shop, for a 512MB Compact Flash card for £3.99 I thought what the heck. For Your information I upgraded my 256MB to 512MB in the same way as CiscoNews have shown here: http://cisconews.co.uk/2007/12/27/asa-5505-flash-memory-hack/

    I then decided to look on the Web for the Official Cisco 512MB CF card. it retails at £430....

    Erm yes, over 10000% (YES TEN THOUSAND %) profit for Cisco compared to my cheap upgrade! (thats some mark up value for a Compact Flash Card.

    I then decided to investigate the Memory Stick (onboard ram) Specs which turn out to be a 256MB 184pin DIMM of PC3200 (400Mhz) CL3 Unbuffered, and Non-ECC RAM.

    Since I had two 512 Sticks of exactly the same RAM Specs sitting on a motherboard from and old PC which had been stripped out of a case, I decided to take the plunge.

    and Guess what!

    Hardware: ASA5505, 512 MB RAM, CPU Geode 500 MHz
    Internal ATA Compact Flash, 512MB

    The ASA5505 booted up straight away. All I can say I have saved myself a bundle of money on upgrading to the "Cisco memory"

    I must warn users however this would invalidate any warranty that you would have if you had to returned the unit to Cisco with the "new upgraded memory"
    but then again, you always have to old ram to put it back as you found it:)

    Wanted To Try The Same Thing

    ...I just purchased an ASA and I'm looking into performing the same memory upgrade so I can use IPS and have enough memory to handle it as well as some other things I want to try with it. My question about the memory upgrade is that although the router is recognizing it, can it actually use all of the spare flash and ram that's installed? Also, I haven't been able to find any documentation on the memory limitations of the ASA 5505. Only what the base memory is for the units when you purchase them.

    Well its been a while since I upgraded my ASA5505's Ram to 512Mb (Jan 2008 I think) but i decided to play around again with some different Kingston Ram.

    The old Ram was Kingston KVR400X64C3A 512Mb, The new ram I've obtained is is labelled:

    Kingston KTH-530/1G 2.6v

    It works straight away without any issues.



    The ASA5505 with 1Gb of Ram should work pretty well now.


    Brand: Kingston
    MPN: KTH-D530/1G
    Memory Size: 1GB
    Specs: DDR PC-3200 • 400 MHz • CL3 • 2.6V
    Detailed Specifications: Standard 128M X 64 Non-ECC 184-pin Unbuffered DIMM Double-Sided Gold
