Corsair 8GB SODIMM Mac Memory Kit (CMSA8GX3M2A1066C7)

5 Stars- techdad

Corsair mac memory

     

Does your Mac only have 4GB of RAM? Upgrading the memory in your system is still one of the quickest and easiest ways to boost its performance. Buying it from a memory company instead of Apple will save you TONS of money. Though, unlike high performance desktop memory, there aren’t as many distinguishing factors when considering which SODIMM to buy. Pretty much all the major manufacturers have similar stated performance specs, so why would you choose Corsair’s Mac Memory Kit over the others?

PROS

  • Great price
  • Tested at Apple’s compatibility lab
  • Proven reliability
  • Excellent support
  • Lifetime warranty

CONS

  • Hard to remove from packaging

INSTALL & MEMORY TEST

Installing the Corsair Mac Memory kit in a 15-inch MacBook Pro was quick and easy, though I struggled a little bit trying to remove the modules from the plastic packaging. The memory was immediately recognized by OS X and everything ran quickly and smoothly. Rember verified the memory size, type and speed.

The Corsair kit also passed memory tests with flying colors.

RELIABILITY, VALUE & SUPPORT

The timing for the CMSA8GX3M2A1066C7 is 7-7-7-20, which is the same as the kits offered by the other manufacturers. So then why would you consider the Corsair memory kit over the others? The most obvious is price. The Corsair kit has a very competitive street price. Did you know that Apple charges $400 for an 8GB memory kit?!

What might be less obvious is that the Corsair kit has been tested at Apple’s compatibility lab. This ensures that the memory you buy has actually been tested to work with Apple’s products. Though I’m sure that kits by other manufacturers have been tested for compatibility, the fact that Corsair went through the trouble of testing their memory at Apple, provides extra peace of mind and tells me that Corsair is willing to go the extra mile for their customers.

Additionally, Corsair’s top notch support is always something to consider. Sure, like Corsair, many memory makers provide lifetime warranties, but how good is their support and how simple is the RMA process? If your Corsair memory goes bad, getting a replacement takes just a few short steps and their turnaround time is very reasonable. If you’re in a hurry, you can even request an advance replacement (provided that you give them a credit card #, just in case you don’t return the defective memory).

SPECS

Density 8GB (2x4GB SODIMM)
Speed 1066MHz (PC3-8500)
Timing 7-7-7-20
Type DDR
Format SODIMM
Pins 204
Voltage 1.5V
Warranty Lifetime

 

CONCLUSION

You can buy memory for your Mac from anybody, but why would you? You’d might as well get it from a company known for high-performance, reliable memory, who actually tested their memory at Apple’s lab. The 8GB Corsair Mac memory kit is a terrific value and I recommend it to anyone looking to maximize their Mac’s performance without sacrificing reliability or top notch support.

    For the 2nd time I had to go back to my retailer to swap this product since none worked for me – 1st was 1333 2nd 1066 (Mid 2010 Macbook pro). Not sure I’m buying any Corsair product anytime soon …

    I recently bought this product and couldn’t get it to work with my mid-2010 MacBook Pro. After chatting with Corsair I discovered that there are 2 versions of this product. Originally the IC density (the number of black rectangles on the sticks) per stick was 8 x 512 MB. It turns out this is more than MacBooks, at least of 2010 and older, can handle. So Corsair updated the product to have 16 x 256 MB ICs (as you can see pictured above in the review). Basically the issue reduces to: my retailer had old stock. If you buy this product, have an “older” MacBook and kernel panics after installing it check the IC density and chat with Corsair directly if it’s too high; they’ll send you a compatible replacement.

    @wendyjo
    I can definitely understand your frustration, since bad RAM can be difficult to troubleshoot and identify. My wife has been running the Corsair kit on her MacBook Pro at work and hasn’t had a single problem (knock on wood). And she uses it for 10-12 hours a day. When I can, I’ll ping Corsair and see what I can find out.

    I am having this same issue..
    macbook pro 10.7.4 lion
    random kernel panics
    corsair warranty is fine as they are paying shipping both ways, but i’m now waiting on my 2nd replacement of corsair ram (which means 3rd pair, of 8gig each sticks)

    i am frustrated because memory tests run clean, so I can’t understand why/how this is happening..
    can someone give me some technical insight ?

    thanks

    There is a lot of people experiencing the same problems with this faulty memory. Read up on any popular site and you will find users dealing with random crashes.

    Corsair needs to fix this product or recall their recent batch because this is just causing a lot of stress for both seller and customers.

    Why continue to promote and produce a faulty product when you’re just going to ruin your creditable along with losing money on fixing the memory kits.

    @Raphael
    That seems unusual to me, but I’m sure if you get in touch with Corsair, they’ll RMA it for you both, no problem.

    Good luck!

    @Tito Have you tried running the test on your old memory? Does it pass OK? Have you tried to exchange the Corsair RAM?

    Yes, I get the same results in every test. Now i change my memory back, to my 4Gb.

    @Tito Do you get the same test results every time? I would either try to exchange it from where you purchased it, or contact Corsair support. You can contact them at http://www.corsair.com/support. I’ve never seen Corsair memory fail, but I’m sure it happens from time to time. Good luck!

    @Tobias You’re very welcome! I think you will be very happy with it. Just be very careful when removing the memory from the packaging. I tried to pop one memory chip out and it literally flew two feet into the air. Luckily, I caught it on the way down. Thanks for reading and take care!

    Thank you for that nice suggestion.
    I also ordered this 8gb kit for my MacBook pro 13″ (mid 2010), but still wait for it.
