The chips I bought 6 months ago have 'failed'. My MAC keeps randomly crashing, and the Hardware scan indicates a memory failure.

So far so good for me, I'll keep monitoring mine as well. I would contact Corsair to see if a replacement will be granted under warranty.

Martin, was it the right memory module for your Mac? The module must be Mac certified, otherwise you will experience this problem.

My Mac runs just fine I admit I didn't pay that much attention to it other then proper installation. I'm running four 4gb cards and there hasn't been an issue. I do advise the if you are only upgrading meaning adding ram not replacing. Leave the original ram in its original location and just add the new ram to the open slots. Hope that help you in your decision.

I have this MB, and it absolutely refuses to work with all 4 slots filled. Didn't realize I had one of the "bad" ones until I tried to move to a 4x4Gb ram setup. Only the two ram slots farthest from the cpu work. But I love this board enough to be here shopping for a second one - makes a great fakeMac.

go to apple.com and they have a memory list and you have to find the date your computer was made and compare it to find the right one. don't trust any other route.

I don't know if it supports this particular chip but it does support 1866. Upgrade the bios to the latest version. Set everything to DEFAULT SETTINGS. If you still get the bsod, try one chip at a time to determine which chip is giving you the problem. If you only have 1 chip, change slots.

I think my computer said that to me when mine (my memory card) went bad. This is why I purchased this item in the first place. I think I pulled one stick out and then the other - and it booted up when I did that. It was a few years ago though, so I might no be remembering right.

This item is a recall from a few years ago due to some hardware issue with a batch of Intel processors. Do some web research to get the details.

That's what I have. This memory kit made an incredible difference! Just to be safe, click on your apple menu, then "about this Mac". Make sure it says "1333MHz DDR3". You should be good to go. Enjoy

I'm considering upgrading the memory- does anyone know where the cheapest and most reliable place is to buy compatible mac memory?

I have no idea Vu, the chips I got screwed up my system to the point I had to reinstall my OS. They are sitting on my desk looking at me right now.

My recommendation would be to buy another brand. I had a card RMA'd two times. It now sits in the shelf collecting dust.

I'm not a teck so keep that in mind. I had a problem too at first when I saw there were 2 separate areas for the memory chips. Try switching them and make sure they are securely inserted. Other than that I don't know. You might want to go to a place like Compusa or something. Sounds like an installation problem more than defects.

Glenn Levy, you are INCORRECT. Unlike older iMacs, the RAM in Intel iMacs is a user installable part and does NOT void the warranty. I would recommend upgrading to at least 2 GB (1 GB is bare minimum these days). Anything you can do to reduce the amount of reading/writing to the hard drive will boost overall system performance.

Sorry, but it's unreliable. It freezes my Mac laptop and results in subsequent erratic performance. I've heard this from other buyers too. Don't buy.

I would recommend that you look at the specification for your MAC under the "About this MAC" option. You will see the memory module that is currently used in your computer (Ex: Memory 8 GB 1333 MHz DDR3). If there is a match, you should be fine. You could also search for the recommended configuration in the apple website for your machine.

out of 3 modules i have purchased 2 ended up being faulty so i do not recommend this memory. Buy corsair vengeance.
