[Lazyweb] Help me buy RAM.

Are any of y'all smart & confident about Mac G5 RAM upgrade paths?

I need an additional gig of RAM, but I don't wanna pay the $20+ premium for brand-name memory; that's for suckers. Unfortunately it's been many years since I've bought Mac memory and I no longer know what's what.

According to System Profiler, I have four DDR SDRAM DIMMs installed, two speed-rated 2700 and two 3200. I note they are not DDR-2, even though I see that newly sold G5s seem to ship with that more efficient type of memory.

When I look at DDR DIMMs on pricewatch.com, I see some nicely priced ones but they're stuck all over with warnings that one's motherboard needs certain chipsets for them to work. I've no freaking clue what's on my motherboard, coz I have a Mac. I have a sneaking suspicion that they'd work anyway, but I can't be sure. So confusing.

Any advice?

Hm. I have for many years been carrying around conventional (and therefore quote) wisdom (unquote) that RAM is RAM, supported by the fact that I've never had a memory blowout. Unless I have but I've forgotten...

I didn't get big-name-brand memory (having made the purchase right after joecab's first comment) but I did at least buy from a vendor with a good rating on pricewatch. (There are many vendors with bad ratings, to be sure.)
