PC100 memory question
I've got a G4 Cube with these three PC100 sticks:
- 512 MB PC100 2-2-2
- 512 MB PC100 2-2-2
- 128 MB PC100 3-3-3
Now, I know OS X LOVES RAM, so I fed it with as much as I could for now.
What I'm curious about is . . . I know 3-3-3 is slower than 2-2-2. But I also know that the more RAM you add, the more you help performance.
I also know that having a single 3-3-3 chip is going to force the entire bus to run slower. If I removed the 128 MB stick, the two remaining 512s would run at 2-2-2. But I'd have less RAM. (Admittedly not that much less, but less.)
Is it worth it to remove the 128 stick, so that the whole thing can run at 2-2-2, or is the performance gain from having that extra 128 MB of RAM worth having it all run at 3-3-3?

Memory is relatively cheap these days. Why not just go pick up a faster 128 MB DIMM if you're concerned about it?

i doubt that 128 MB of ram less will make a difference when you have 1 GByte of RAM, i doubt either that you will see a difference between the two types of memory in real applications, you should only see a difference in memory benchmarks.
