Na, ram is ram. It is just like FDDI cables. I spent $250 on FDDI cables, and then found out that I can get the exact same cable for $50 each.

Yep, it is... However, just to prevent any possible misconceptions.. In the SIMM world you still have different types of SIMM, however, I've found that most commercial router platforms that use SIMMs, use 72 pin parity SIMMs. Non Parity and EDO tend to give you a bad day. Chris
