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...

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.
