if you know what you are doing, you'll be fine. yes I agree any generic ram that isn't spec'd for a mac can and will give you issues, but as long as it fits the specs of said mac, buying the cheapest ram is best.

So all RAM that is "spec'd" for the Mac is at the same tolerances?? (answer: WRONG)

Please provide an example of what "specs of said mac" would be? Any model number would be good for an example. 

here's all the memory specs for PowerMac G5's for example.

http://docs.info.apple.com/article.html?artnum=86414

so as long as you get mac spec'd ram that meets those requirements you are golden.

You really have no idea what you are talking about. Those are no where NEAR complete specifications for a RAM module. Yes, they probably work in simple configurations.

no, you are looking too deep trying to find a problem where there is none. the above link is all you need to know to buy ram for a powermac g5, they will work in any configuration, those are the "certified specs".

You keep dodging the questions of who says they are certified, and what does certified mean. You makde up the term. There is not a reference to "certified specs" on any of the sites you have given me.

No where does Apple publically specify if RAM modules should be buffered or unbuffered. There is a cost difference between the two. There is a heat difference between the two. There is a performance difference between the two. Several of the sites that you have posted list both of them as parts for the Power Mac G5. Obviously, these manufacturers are not providing RAM to manufacturers specfications, or there would not be these variances in modules.


Simply put. If I purchase 2 x 1 GB sticks from Apple for a given system, they will work together.

sure, and you will WASTE, $130+ in the process. you just aren't a very experienced shopper that's all. you sound like the type of fool that buys premium gas when your car only can handle regular unleaded. you are a victim of marketing, not understanding actual "specs".

Oh good, you want to talk about another subject that you know nothing about, and that I have researched extensively. To make it quick and painless, premium gas USED to get you more detergent. Then the EPA made detergent and additive regulations. Detergent level's uniformly dropped. The auto manufacturers stepped in and pressured the gas manufacturers into the "Top Tier Gasoline" program (due to increased warranty related fuel injector issues). Any gas supplier that adheres to these guidelines must 1) put more additive in their fuel than the EPA requires, and 2) keep it uniform across the fuel octane grades.

All higher grade gas in the US buys you is more octane. Only one of my cars actually requires it, so that is the only one that gets it. My other two and my motorcyle run great on 87, which is the lowest I can get here.

Back to memory. You are wrong again. There is a difference between modules. Two of the links that you provided me, when I followed YOUR instructions, both documented these differences. They both stated that there was another tier of RAM that would match manufacturer specifications.

Your own evidence convicted you. Don't look for a second career in law.



If I go out and purchase 2 x 1GB sticks individually that meet the "PC3200" spec... there is no guarantee whatsoever that they will work together. There are still several variables that are importantant that these "specs" do not address.

That makes me far from "golden"

yes, but 99% of the time they will work just fine. if you buy large qty's of ram like I do, you learn to take the tiny risk. 

I think you pulled that number out of the air.


Again, as I pointed out earler, Samsung has 6 DIFFERENT SKU's for a 512MB memory module for DDR2-533. All of which qualify as DDR2-533. Each has different performance characterstics.

yes, and Apple only has ONE spec for each machine type, so I buy to spec, then find the lowest price for that certified spec, that's why i'm golden, while you can only afford bronze.

You clearly do not know what a spec is, as you have demonstrated. Apple could have multiple specifications for different parts. You clearly do not know.

Again, what qualifies a memory module as "certified". Please provide a link to this. In the mean time, I will assume that you just made it up.
