I finally upgraded my 15" TiBook (1Ghz) from 512MB of RAM to a gig.

I ordered the more expensive kind from MemoryX:

512MB Apple/Samsung OSX/OS9 PC133 PowerBook SODIMM (p/n M9088G/A)

instead of

512MB Apple iMac 144p PC133 1" SDRAM SODIMM (p/n APL144Y512L)

because the more expensive is supposed to run cooler than the cheaper stuff. (At $50 per SODIMM, it better run cooler, huh?)

Now, since installing it, my fan has actually been running more frequently (and seemingly for no good reason). I've had great experience with MemoryX in the past so I have no reason not to trust them. But I'm kind of curious anyway... is there any way to tell by looking at the RAM which version it is? Obviously the amount of memory is visible in the Apple System Profiler. But what about the quality?

Maybe because your system is running hotter?

Someone once told me that Ram is pretty much all the same. Unless you go with really cheap ram you should be okay.

The extra ram module will heat up the PB a bit more, so that's probably why you're getting the fan on now. This happened to me with a Pismo, I shoved a 512mb stick from crucial memory in it, and one day I heard this crazy whirring sound, it was the fan which i assumed the Pismo never had, never heard until i put the ram in.
