I've had similar issues with older PCs myself. It's a shame that some of the old macs have bad RAM slots, I did not know about this until I read your post. 
I do know that RAM runs faster in dual channel mode when you have two identical sticks. Although technically the RAM is twice as fast in such a scenario, in practice, it's anywhere from a nominal improvement to about a 10% improvement in speed, thanks to the CPU's cache.
My macbook now is running in single channel mode thanks to a stick going bad. I didn't have a replacement, so I just left one 8GB stick in there. It's 1600mhz and it's still 8GB, so it's plenty. There is definitely a noticeable (albeit relatively minor) difference in speed (mostly at startup) but it's not too significant. And it's well worth not having my computer randomly crash every few hours...
1GB of RAM isn't bad for an older G4 powered MacBook (ahem, iBook
). Glad it's working better now, and nice post!
