Review on 🖥️ DUOMEIQI 16GB RAM Kit (2 x 8GB) DDR3L/DDR3 Memory 16GB 1600MHz SODIMM RAM PC3L/PC3-12800 2Rx8 1.35V/1.5V Non-ECC Unbuffered Laptop RAM Notebook Memory Module by Alan Sitton

I bought the DUOMEIQI 8GB (2 x 4GB) 2RX8 PC3-12800 kit for my 2010 27" iMac with i3 processor. There are many memory issues with these old iMacs so I was afraid it wouldn't work but it was cheap and I had other devices to use it in. Although it's faster memory they work fine with the original 4GB that came with it ( 2x2GB). OSX runs 1000% times better with 12GB of memory. With 4GB the system was useless. I'm pretty sure this will work in a 2011 iMac and the speed spec is correct for 2011. In 2010 the memory runs at the same speed as the original 4GB, so faster RAM isn't an issue Don't worry about all the talk about having special memory for 2010 he must buy, they are perfect, no failures in 3 months of 24/7 operation. If you have a 2010 i5 or i7 iMac, you can use 8GB modules to add even more memory, but the i3 won't boot with 8GB modules, so stick with those 4GB and it'll feel like a new computer feel.
