I have the last model g4 powerbook, 1.67ghz, 17", with one gig slot open. The chip in the other slot is a DDR2 SDRAM PC 4200S 444 SODIMM.
Other manufacturers said I need a PC 4200, or PC2 4200 chip. Crucial's machine scanner says I can use a DDR2 PC2 5300 chip, and chips of different densities can be mixed since my computer doesn't support dual-channel memory.
Scan URL from my machine:
Apparently I can order a single 1gb PC2 5300 and add it to the empty slot. Is this a significantly faster chip than the PC 4400s that is already in it, even if it's compatible?
If so, will installing a kit pair of PC25300's speed up the machine? Use more power? The cost is insignificant to do a pair if the performance increases, and may be better for the machine life. Which install is most prudent forgetting about cost?

Yes, the 5300 is faster than the 4200. I'm not sure I would consider it significant or not. That would depend on your perceptions. You will notice a difference though. Even though, as you stated, that your system is not dual channel capable, it will benefit from the kit. A kit is basically a matched pair. And a matched pair tends to be far more reliable than two random individual sticks. Hope that helps!
