I received prices for upgrading RAM memory in both a Cisco 7000 and Cisco 7500. Ouch! My question is: the 7000 appears to accept standard 30pin SIMMs while the 7500 accepts 72pin SIMMs. Since I can purchase lifetime memory (60ns, true parity) for orders of magnatiude less, why shouldn't I? Has anyone really tried this? Other than Cisco claiming that future problems are related to the non-Cisco memory I installed, what problems might I encounter? Are there less-expensive "Cisco certified" memory dealers? Thanks. -- Joseph Thomas E/Mail: jpt@networkcs.com Network Computing Services, Inc. jpt@magic.net 1200 Washington Ave So.

You sure can, most providers upgrade the memory on their ciscos with 3rd party RAM, the cisco stuff just cost to much. I dont know of "Cisco certified" memory dealers, but just buying decent RAM from any good vender should be fine.
Thanks.

call up TAC, and get the "AVL list - Authorized Vendor List" for your router. A quick search for AVL on the main site at cisco returned a few interesting pages: "don't do this, we're not responsible, etc." at http://www.cisco.com/warp/public/770/10.html "RAM for RSP or VIP cards" at http://www.cisco.com/warp/public/770/40.html which has links to some great pictures at http://www.cisco.com/warp/public/770/compare.gif and http://www.cisco.com/warp/public/770/ruler.gif some of the other links talk about the AVL for other products as well. have fun, rob

Be aware that this recommendation is not complete without the caveat that Cisco will not support your processor card if you stick unapproved third-party RAM in it. It's very important to use QUALITY memory in the box. With that said, Cisco does have an AVL (authorized vendor list) for third-party memory. Kingston carries this, and will even cross-ref the Cisco part numbers for you. /cah

Sorry let me change my above "decent RAM from any good vender" to "good RAM from any decent vendor." I was not aware that was such a big difference between decent and good RAM. Are decent vendors ok, or do they need to be good vendors like the good RAM? ;-)

True. I also don't recommend you broadcasting to Cisco that you are doing this.

Ciscos have a greater expectation of on-spec behaviour from RAM. lots of really borderline stuff that works fine in the random PC clone doesn't cut it in a Cisco. in my experience, the Kingston stuff that cross references out to Cisco equivalents works quite well. richard -- Richard Welty NeWorks Networking, Inc. 518-244-9675 rwelty@neworks.net http://www.neworks.net/
The only specification is true parity with tin leads. Do not use gold leads as gold on lead = corrosion. Can't remember the speed though...
