Of course more RAM helps! Doesn't matter what computer you have - if you are running Mac OS X, you need to get all the RAM you can. I suggest having AT LEAST 384 MB of RAM to run …

Thanks Cheesepuff. What are you running? How much ram do you have, and what kind of improvements can I expect?

I had a PowerBook G3 400 MHz with 192 MB of RAM, and running Mac OS X 10.1 was useless because it was too slow. I upped the RAM to 768 and it had a HUGE improvement from booting up…

Thanks again. Just curious: why do you have two laptops?

You bet it makes a huge difference. I have a Pismo 400 and upgrading to os X I did 2 things upgraded to 5100 rpm HD (the 48gig) and loaded to 768 RAM. Best investment I could h…

I think it is VERY difficult to get pageouts in OS X if you have more than 384mb of RAM. I recently boosted my Powerbook Ti 550 from 256 to 384. OS X was slightly more responsive, …

I've got 1 gig in a Pismo 500. It makes all the difference. It's the most important upgrade you can make. My wife's iBook only takes 320mb and I wish it would take more. PeteWK

Going from 256 to 512 or 768 will yield a significant gain in performance, but going on from 768 to 1gb doesn't give much gain. At least, that has been my experience.

Ram is always worth the price. Everything will become much more smoother.

You can't afford not to get more RAM.

I upgraded to 640 at the same time that i upgraded to 10.1 so I wasn't able to what the difference was. However I also replaced the hard drive with a larger (but I think smaller) …

How'd you get into Princeton with that kind of grammar? You're very right, though. Uprading from 128 megabytes to 192 megabytes allows the operating system 50% more breathing ro…

Thanks to everyone for these posts. Very helpful and thoughtful and pursuasive... I'll be ordering 256 more megs tomorrow from OWC. That's all I can afford... (Canadian dollar…

Actually, I think even MacWorld reviewed computer speed with various upgrades... Can't remember what issue though. The cheapest upgrade that made the most difference in performanc…

When I first got my Pismo 500 it had 256Mb and a 12Mb hardisk. After installing OSX beta it used to thrash the disk and ran nearly full all the time. OSX was unusable. Now I have …

Take a look at the MPC7445 chip: http://e-www.motorola.com/webapp/sps...30450467M98653 Looks to me like Apple might use this chip in the next PowerBook?? Faster and cooler than …

mmm, yah, but at 140 to 180 percent increase in power usage (goin by that chart) you'd see a corresponding drop in battery life...ugh... not any time soon... :r

The PPC is just one component it wouldn't produce a directly proportional drop in battery life. Besides, the battery could be improved -- larger, denser (heavier ) designs are p…

How long did it take to get from 500 megahertz to 667 megahertz? Too long. The fastest Apple's jumped in portable "megahertz" is 167 megahertz, and that took two PowerBook revision…
