That is the same RAM I purchased, except Kingston seems to be selling
one DIMM for $73, whereas the company I purchased from, ewiz.com, is selling the Kingston G5 kit (two of those DIMMS) for $89. Remember, G5 RAM must be installed in pairs. Here is the information I posted in an older thread:
Here's my advice: Don't buy the cheapest (i.e. Coast-to-Coast/1800-4-MEMORY), and don't buy the most expensive (i.e. Crucial). When you buy from cheaper companies, you don't get name brand RAM. Most all RAM is produced by a small number of oversees vendors, but I have been told that the cheap resellers use chips that failed the rigorous testing the name brand companies perform. Here's a secret, though: Crucial is not the only name brand memory seller.
There are at least five name brand manufacturers: Crucial, Kingston, Viking, PNY and Corsair. (I wasn't aware Samsung is also major developer.) Crucial is too expensive, IMO, and their site, while pretty, is unhelpful because their memory selector presents too many module variations.
Kingston is more reasonably priced than Viking; both provide lifetime warranties. OTOH, PNY, the cheapest of the name brand RAM, only provides a 10 year warranty. Finally, I've written off Corsair entirely, since that company seems to cater exclusively to PC "enthusiasts," and a search for Apple yielded 0 results.
I've found the easiest path to price comparison is Froogle, and it's important to compare prices - one could easily get screwed over otherwise. Try search terms that reference the specific part and/or part number you're looking for. Be aware of the fact that some companies sell/price the modules individually, whereas most others sell/price them in kits. (G5 RAM needs to be added in pairs.) You'll find a lot of smaller tech companies through Froogle; I bet most are reputable. The really difficult part is determining which companies have which parts in stock and then figuring out which is the cheapest after taxes and shipping.
For my G5 I selected Kingston brand RAM. The cheapest reseller of a 512MB kit was at the time ewiz.com, charging $92. Now I see the price has dropped slightly to $89.
Here is the direct link. In comparison to generic RAM this was/is a good deal, and I feel better using high quality components. (A generic 256MB module failed in my iBook months ago, prompting me to look to name brand RAM.) ewiz.com does charge CA tax and $11 shipping, I believe. Hope this helps!
Addendum: bob_hearn taught me something by referring to "stacked RAM," a term which I had not heard of previously. According to this
Mac Observer page, "stacked RAM" is synonymous with cheaper, lower-capacity chips. The RAM is stacked because more chips are required, making the module bigger and requiring more power. Although I could be wrong, stacked chips are only really a concern with laptops, because bigger modules may not fit properly in them.
