Factory Original PowerBook RAM?

Question

What brand of RAM did Apple ship with the PowerBook G4 15" 1.5ghz, and is this the same RAM you would get if you bought RAM through the Apple Store? Looking to upgrade my RAM, and from all of the headaches other people have had with PowerBooks and RAM upgrades it seems like the best route would to be to get the same RAM that the PowerBook originally shipped with.
PowerBook G4 15" 1.5Ghz   Mac OS X (10.4.3)

Welcome to the Apple discussions.
Last year, Apple was using Samsung memory. Apple would love to sell you additional memory, as you generally pay twice what you could buy it for on the open market.
Generally, the only time people have difficulties with RAM is when they try to go cheap. We know the PB's architecture is RAM-sensitive. If you stick with known brands, three of which are Samsung, Crucial, and Kingston, you should be OK. Crucial, www.crucial.,com, guarantees its RAM will work as long as you use their web site memory selector. I'd expect Kingston would too (note, their Valueline RAM isn't for PB). Lifetime warranty is helpful another indicator. I've used all three brands manufacturer's recommended RAM sticks in PB's, with no issues.
If you go Kingston and want to order from their website, www.kingston.com, click specials, click promotions (might have those two reversed), click notebook memory, do the machine lookup, and you'll save up to 25% off their list. They also give you prices from several other sellers.
One seller of Samsung is Other World Computing, and their memory is http://eshop.macsales.com/shop/memory/iBooks-PowerBooks/G4-Aluminum/ Samsung is about half way down the page under the 'OWC PC2700....' category.
