Early 2011 MacBook Pro 16GB Memory Test Failed:mad:

post #1 of 3
Thread Starter 
I have the early 2011 MacBook Pro, 13", 2.7Ghz. I have been running 8GB of memory for a while now. However, yesterday I installed the following Corsair memory into my MacBook Pro:

Corsair 16GB

I first ran Memtest86, booted from a cdrom. It failed within roughly 5 minutes. I then booted into Mountain Lion, and tried Rember. It failed quickly as well. I switched the memory sticks (slot 1 to slot 2, slot 2 to slot 1) and have since ran rember and memtest again. Rember failed on the 7th test, and I booted into single user mode to run memtest (not Memtest86). I am not sure when it failed, because I couldn't figure out how to scroll up, but I can say that tests #1,#2,#3,#10,#9,and #8 were successful. Is there someway I can pull up the log from the memtest that I ran? "memtest all 10" is the command I ran.

I do not know if perhaps one of the sticks just wasn't seated properly, or if one of them just didn't like the slot the first time around. I just find it so strange that I can go from failing within 5 minutes to going for hours without failure.

Am I foolish for expecting to be able to run 10 tests without error? If I had picked the number 5 I would be much happier feeling right now. I bought it from Amazon. I do know that Corsair makes "Mac" memory, and I also know that this model MacBook isn't guaranteed to work with 16GB. However, I read a lot of the reviews on Amazon and there were many 5 star reviews for this memory/MacBook Pro combination.

What should I do? Anyone have experience with RMA Amazon memory? I still have the 8GB. However, I never ran any tests on the 8GB and currently the 16GB shows just as good performance with virtual machines/etc.

I suppose the right thing to do would be to remove one stick, run the test. If it passes, place that stick in the other slot and run the test again. Then repeat with the other stick. But should I run each of those tests to the #10?

Please, I would like any advice possible. What should I do?

You could try the test with just the Corsair memory. Is the reseller Amazon themselves on Amazon? RMAs should be fine. Just fill out the web form on Amazon and return/exchange the defective memory.

I have two slots, currently inside is all the Corsair memory. I do not exactly understand what you are suggesting...please further explain. BTW, it was shipped directly from Amazon so it should be smooth. I just am afraid that I may go through the process of RMA'ing and the newer memory may not work "flawlessly"' as well.
