I've been heavily researching RAM for my MacBook Pro. I used to build PCs for my parents and a gaming rig for my brother, so I enjoy researching products and finding the best stuff out there, even if it means spending a little more than something I find for a "great price". Its been very difficult for me to decide on which RAM to go with. Alot of people have gone for OWC. I am not familiar with this brand (does not mean its bad) I just prefer to use a product I have used and am familar with. In all of the PCs I have built I use Corsair. I've used the higher end sticks for my parents comp (it was also built as a semi gaming rig for me at one point), and the Value Select stuff for my Bro, knowing he would upgrade it later. So naturally I'm really wanting to use Corsair. Unfortunately Corsair does not offer a 4GB kit for the MacBook Pro. Right now, I'm set on buying from Crucial, another comany I'm familar with and know is of high quality. So here is are some thoughts and ideas I've happened upon. I know one of the brands Apple uses for memory is Samsung. I've searched (and have been given links) for their memory, and their price for 4GB comes very close to the $750 that Apple is asking for. Here is an e-mail to Corsair, and their response (edited but for main question): "Is Corsair going to be releasing a 4GB kit for the new MacBook Pro's anytime soon? My other consideration at the moment is Crucial, which while I know they are a reputable brand, I would prefer to use a product I am not only familar with, and have used in the past, but trust." Reponse: "There is not currently a 4GB kit available, however there are 2GB SO-DIMM modules that should be compatible with your system. The part number for this module is VS2GSDS667D2, 2 of these modules will get you to your goal of 4GB." Well, I checked out this RAM, and it as well is very very pricey. So again, going this route I would spending the same if not more than Apple, even if I find this a very trusted brand. On another note, Newegg offers a 3GB kit for the old MacBook Pro's. It consists of 2GB+1GB which runs for $175. I was thinking, if you buy two of these, which comes to $350, you would be getting 2x2GB sticks out of it. It would be half the price of Apple's upgrade, however, you would have an extra 2x1GB of memory. Maybe you can find something to do with them. So, I think in the end I'm going to buy from Crucial ($280), and leave it at that. This post was just to shed some light on what I've found, and what the possibilities are out there. I could have however, overlooked something, so if there is something you find that can hone in on this search, lemme know! But, mainly, the research is b/c I myself do not want to use OWC or some of the other brands I'm in no way familar with. I want to use something I have used, and seen, and am familar with with over 8 years. Thanks.
