FWIW: I have had two experiences with RAM from Fry's. The first was in an el-cheapo eMachines PC 5 years ago, and the other was this year in my eMac. In the first case, the 64MB chip refused to show up as more than 32MB. In the second, we bought Corsair RAM, without realizing that, even though "all RAM is equal", Corsair clearly states (not on their webSITE, but on their FORUMS) that they DO NOT SUPPORT Macs, and if the RAM "goes bad" in a Mac, their warranty DOES NOT COVER IT! Of course, we had Kernel Panics galore, and the AHT showed that there was a flaw in one of the sticks we had bought, so we just returned them. So, even though "all RAM is equal", I would still be cautious about RAM lacking a one year warranty, or even RAM that is not specifically indicated for Macs. Even in that case, I ordered RAM from 4AllMemory for an iMac G3 333Mhz, and they sent the wrong density sticks. Granted, this does not mean the RAM was faulty, and they did eventually replace them with the right one. There is, however, something to be said for reputation. I have even seen differences in the PC world, where RAM chips are indicated either for Intel or AMD systems (and I am not sure of the reasons for this, if somebody else is, please inform...without flaming). Anyways, just my 2 cents.
EDIT: And yes, I am aware that my experiences are in no way scientific tests, nor are they even necessarily indicative of the quality of Fry's/other companies products. I merely offer them as anecdotes.
