First of all I must say that I have a small odyssey behind me get first ordered CSX RAM and delivered twice a false Amazon goods! But this was only partly Amazon's fault, obviously the lower seller had false information to goods made and the package Packer has simply resorted to only in the tray and not respected it if he actually CSX RAM holds as in the hands, maybe it was him do not care - But that's really blame the Amazon has to take upon himself when the "smallest" something employees do not care. Well, I then ordered Voelkner Corsair RAM, 8GB SO-DIMM 8500 DDR3-1066MHz, was not working. Returned. In the Amazon, recommended for all Macs, Kingston RAM ordered ("Kingston KTA-MB1066K2 memory 8GB (1066MHz 204-pin SO-DIMM, 2x 4GB) DDR3 Kit for Apple Notebook"), also same specification as the Corsair - ran just little! Although I had only tried once because a single RAM slot in the Mini, the top, and each 4GB latch itself ran there, but together, no chance! 3-way tone at startup (memory test failed), 1 Drawer sound (recognized no memory) at startup or simply nothing happens. Returned - and the memory should be explicitly suitable even for another Apple model. And both Corsair and Kingston are so well-known, quality brands. So be it. My last attempt was now to order the Samsung memory after the Corsair RAM (40) and the Kingston RAM (about 52) with here was about 60 of the most expensive on Amazon. Not that I previously wanted to save money - now, perhaps! - But as I said the other two brands are really not a scrap! Anyway, before 2x 2GB Samsung RAM was installed in my Mac Mini and I thought to myself: "Probierste times the same brand". You know what's coming, so the 5 star with whipped cream on top: reingesteckt, turned, running. Unhesitatingly identified and in the system are also 8GB RAM, twice OK in the Memory Info under "About this Mac" - super "More information ...", everything. However, and please consider this: I've also read reviews of other memory types, and also there were Mac Mini Late 2009 owners who have installed the memory and the system was running right away! Perhaps I had with the Samsung also just luck, but maybe as a guide: if you already Samsung RAM is installed in your Mini, I would not look to the euro in your place and order directly Samsung memory. If there is no such hurry, say you have a few days to test and return the memory each charge can, definitely time to test himself. Hope that your Mac like exactly the Corsair, or Kingston immediately. I for one am glad that the little Mac reassembled stands on my desk and hinschnurrt right.
Finally, a few things on the edge: 1. Installation instructions for HDDs / SSDs, is their great under ifixit.com. 2. I have in my Mac Mini originally built by Apple, "normal" mechanical 320GB SATA II hard drive penetrate you, what a read rate of about 32 MB / sec. and write rate of 38 MB / sec. had (tested with Blackmagic Disk Speed Test for 0.00 from the App Store). Property me here at Amazon the "Samsung 840 Series Basic internal SSD 500GB, 512MB cache, SATA III" bought and although the Late 2009 only SATA II SSD has brought the miracle - even more than the RAM, I'd say. Start time is now about 25 seconds instead of the previous 2 minutes and write rate of 210 MB / sec. and read rate of 270 MB / sec. Installation can make collected, if you have the Mac anyway schonmal open. 3. Reset PRAM, only a purely RAM, boot off second latch pure RAM latch switch, Death and the Devil, nothing has what availed! So if it does not work, simply assumes that it is up to the respective RAM brand and not to any of Hocus Pocus. 4. Do you a favor and do not try RAM which apparently is not running anyway to push with screwdrivers deep into the slot! Brings absolutely nothing, and carries only the risk of damaging the Macs. 5. You have the Mini is not only open to find out what the manufacturer has RAM. In the said menu in the system information, there is a manufacturer code. Enter it in Google and you get links to pages where these manufacturers codes are deciphered. 6. The Mac Mini Late 2009 was from about August 2009 shipped with a firmware containing the EFI Update 1.2, that is, the use of 8GB RAM allows. For the Mac mini Early 2009 again the update was automatically imported with the System Updates or you have to pull and install the update yourself from the Apple support site. The Mac minis before 2009 are not able to use 8GB RAM, There you can work confidently save, it will definitely not work. This is according to my internet research on the RAM controller can only address the maximum specified by Apple RAM sizes.
I hope I could help one or the other to carry out a successful RAM update or to find the right memory for your little Mac, hopefully with had to leave far less frustration when I go through me!
