The system isn't creating a 3.5MB RAM disk at start up or something? It's weird that the Finder would be using close to 4 MB of RAM.
I'd try exploring all the DAs that are installed and see if any of them are doing something that's RAM hungry. If that doesn't reveal anything, try stripping all the DAs out of the system (adn what's the other thing? DAs and ???? go in the System in 6.x) and those other things.
See if the memory usage goes down.
If your machine is booting but the Finder is claiming it's using almost 4 MB of memory that sounds more like a software issue than a hardware issue.
Oh, read more carefully and see that you've gone to a completely different boot disk...
That's weird. I'd start by cleaning the SIMM sockets. Blow them out with some compressed air. Make sure the pins on your SIMMs are clean. Maybe try installing just one pair and see if anything changes....
