Fits perfectly
I had some bad memory chips and decided the replacements be of a larger memory capacity. I've bought from Crucial before so I bought these there too.

This RAM immediately fixed system issues
I bought this RAM to replace the extended RAM that was purchased from another vendor. A wide range of nagging problems went away immediately upon upgrade. My iMac runs like a Mac again!
I have been pleased with Crucial RAM in the past, and regretted not using from the outset this time.

Great price, worked first time, slow delivery
Initially ordered 4 from one of their main competitors. None worked. Company sent another 4 to replace them, and they didn't work (none of them). Crucial's RAM worked the first time.

I added these two cards to my new iMac, which already had two 8GM cards installed. I installed these in every-other slot, alternating with the existing 8GM cards, and everything's working perfectly.

Twenty years of reliable memory
I've been putting Crucial memory in my Macs for over 20 years. I still have a couple of those Macs, including a G4 Cube and one of the first 12" laptops, and they're still running strong. I wouldn't use anything else.

Cost effective memory upgrade for iMac
Crucial is my preferred source for memory upgrades. I have used them on numerous occasions on several different Apple systems. Never a problem. Increased performance at about a 60% cost savings! Their online system to analyze your needs works perfectly, if you need more memory, don't forget to buy from Crucial!
