A friend of mine was using an old iMac mid 2011 and she stated it was constantly overheating and freezing or shutting down. I offered to look at it but she had it in her mind the fight was a lost cause and surrendered.
So, earlier this year she went to the Apple store in her son’s town and ordered a newer refurbished model. Just a few months ago she asked me where she could recycle the 2011. I said, “Well drop it off at my house!” She asked why, what would I do with it and so on. I said, “I will play with it until it dies!” I have always been a Windows user at home and had experience on the very first models so this would be a good learning experience for me.
Well, a few months ago she brought it to me and I cleaned it up and it’s been running great ever since!
The only thing I don’t like is that I wish it was the 27” model and it only had 2 sticks of the 2GB x 10600 1333 DDR3 RAM. Not much for multi-tasking and such but it’s not been giving me much trouble at all.
Tonight I was cleaning out a shoebox of odds and ends and was completely blown away to see I had some packaged 4 sticks of 4GB 10666 1333 DDR3 RAM CL-9.
I double checked the installed RAM to realize it was only 10600. But I decided I was going to give this a try anyway.
I pulled out the 2 - 2GB sticks and put all 4 of the 10666 in here, plugged everything back in and started it up. I was cringing and sort of looking out of 1 eye. LOL It started right up, I went to the system info section and they are all correctly posted and showing status: OK
I only came searching to see what people say about doing this and instead of finding answers, I am only finding a lot of questions from people…I signed up on this site just to reply to this, even though it is about 10 years old.
So YES, the cheaper 10666 is working just as well as the 10600.
P.S. This mid 2011 is a real champ for 2021!!!
