    I had been having issues with my 2011 i7 iMac since Day 1, due to the iMac being very finicky with the RAM I was using (Corsair.)

    Over the past month or so, I've had to try different modules from various vendors to get this machine running stable with 16GB of RAM.

    Here's a list of the RAM I went through:

    Corsair - kernel panics randomly, Starcraft 2 will always crash, occasional graphics glitches in WoW
    G.Skill - most of the time can not even get the machine to boot, once I reach the login window, it will crash
    Kingston ValueRAM - works 100% for the last 8 hours (running WoW, Vent, EyeTV with full 1.5GB RAM buffer)

    Maybe we can continue this thread with posts from peeps who've successfully upgraded their RAM without having to succumb to Apple's pricing, or haven't gone with OWC for their Samsung RAM (I would have done it, but shipping to Canada was a bit high.)

    I picked 16GB of RAM from OWC - the shipping was only $5.03 to Victoria.

    Why would not go for RAM that has been guaranteed to work? Esp. if shipping was five bucks? It would have saved you a month of trouble...

    I installed 16 GB of Corsair without any issues, ran memtest immediately after install, no errors were reported.

    Just upgraded two 2011 27" iMacs at work with 8gb kits from Crucial. Both now run like a dream with Mac OS and a Windows 7 Virtual Machine.

    I ordered 8gb Corsair to add to my current default 4gb. My first time adding RAM to any computer (27" i5 is my first ever computer, off to a good start :) ). Mainly need it because I often have several painting and 3d rendering programs open at once. Hoping for the best.

    I ordered 16GB of Crucial RAM from for less than $100 shipped to Calgary. Nice thing is that there should be no customs, broker fees or border delays, dealing with a Canadian store front. I'll let you know how it works when I install it in the new iMac that's coming next week.

    I have had success with them in the past, including a 16GB upgrade for my current iMac (GSkill) and 8GB upgrades for two 13" MBPs (PNY).

    I had 0 problems using patriot ram, i was hesitant at first but it was way cheaper back then and it's still a bit cheaper than corsair or kingston

    I got the Samsung 8gb from OWC: low price of the kit offset any shipping charges to Canada. Installed and works like a dream. Now waiting for my new 750gb hard-drive to install in my MBP.

    I purchased my 16GB set from, and have had no issues.

    Just make sure your getting the 204-pin set using 1333Mhz and not the 200-pin that uses 1066Mhz, as it was made for the previous generation iMac.

    These days with ram being a commodity item there's no reason to buy expensive brands. The ones that don't work, are simply defective which happens to any Mfg. They all come with warranties so buy price not the name. You'll save money & still get good performance. Besides a month after you install it, that's the last thing you'll be thinking about. So don't get sucked into OWC or other pricey brands.

    i always go with either kingston or OWC. G.Skill and etc don't really impress me and read too many faults.

    Shipping was quite a bit more when I got my quote. Twas like $40 at the time.

    Plus, when 4GB SO-DIMMs are $20-$25 locally, spending $40-$50 plus shipping per SO-DIMM is quite a bit more.

    The G.Skill and Corsair RAM were odd. They'd work sometimes, and then just KP.

    I've been running this Kingston ValueRAM in here for the last 4 days. No crashes or kernel panics.

    I've upgraded about a dozen systems of various types (Mac and PC, laptop and desktop, PowerPC and Intel) and have bought nothing other than Crucial or OWC. I've never had a memory failure. I may have paid a little more but it has been worth it to be trouble free.

    I installed 2 x 4Gb Ram from Crucial to take my 21.5 mid 2011 iMac up to 12Gb. Works like a charm. No issues at all. :)

    Seeing the new posts about Crucial RAM (purchased from Crucial), I posted earlier about buying Crucial RAM. I just bought 8GB of Crucial RAM through (to combine with some other purchases) and they came in very irritating plastic blister packs that not only required shears to open but the RAM sticks were locked into place in the plastic. I was worried about getting them out without destroying the parts. Luckily all went OK. Are direct purchases now packaged this way, or are they still in the easy-opening cardboard boxes?
