Timetec 8GB Compatible for Apple Late 2015 iMac (27-inch w/Retina 5K Display) DDR3L 1867MHz / 1866MHz PC3L-14900 2Rx8 CL13 1.35V 204 Pin SODIMM Memory Module MAC RAM Upgrade for iMac 17,1

Excellent product to double the RAM in my iMac.

Works perfectly with iMac 27" late 2015Upgrading from 8GB (2x4GB) to 16GB (2x8GB) is a noticeable (and best value) improvement.I have several iMacs… on the iMac I use most often I tried using 2x 8GB with the original 2 x 4GB cards (24Gb) and it didn’t work. Good thing, I purchased another 2x 8GB (making 32GB) best upgrade I’ve ever done! I’ve now upgraded all my iMacs with more memory from this supplier. Works perfectly!

My iMac 27 (late 2015) came with a stingy 8GB. I added two 16GB memories back years ago to raise the total to 40GB. More recently, I’ve tried to extend its life until Apple makes a Mac Studio with an up to date processor (namely the M3 Max). I had intended to get 2x16GB modules, but they were currently listed at a whopping $345, about half of what Tim Cook gouges Apple customers for 32GB ($800). Of course, these DDR3s are old technology and supply and demand determines the cost.So, I settled for a total of 48GB versus my ideal of 64GB. For half the memory (16GB), I paid only $25, or just 7% of the $345 for 32GB- a bargain!The whole upgrade took about 7 minutes. I didn’t list the stability because it has only been running for an hour, but it should be fine.

Works with T430. Noticibly faster and more responsive

Great price/value

Clean and easy to open packaging. Installs easy. Works great. Thank you.

Upgraded an iMac and I'm happy with the results. Timetec stuff always works well.

I had never heard of this brand of RAM before...but I had read on a website that this brand was a good option for budget RAM....so I took the bait..because I wanted to save the $40 that I would have spent on the more familiar brands, such as Crucial and OWC.I REGRET THAT DECISION.After installing these TimeTec sticks, it seemed fine...but the next day, while working, my computer shut down unexpectedly. The Crash Report stated it was a Kernel Error...which I had never had until I installed these chips.I ended up crashing several times after this.So I reverted back to my previous RAM sticks and didn't get any more crashes or Kernel Errors.BEWARE of this brand. IT'S ABSOLUTE TRASH.Trust me...if you're a professional that relies on your computer to be the lifeline that pays your bills, then spend the extra dough for the better RAM brands.Immediately after reverting back to my previous RAM, I ordered RAM from the "Crucial" brand. After installing the CRUCIAL sticks, I haven't had a crash since.So my personal conclusion is that TIMETEC is absolute GARBAGE.

La verdad me sorprendio, son memorias muy baratas y funcionan excelente en mi imac, es una de 27" de finales del 2015 y le compre 2 de 8 gb, actualmente tengo 32gb y la compu vuela

Wouldn't let me post pics of my config but it shows all working well. I now have 32MB of memory - these 2 x 8MB sticks + my original Apple 2 x 8MB memory. With the Quad processor and 4 MB 395X video card the computer still performs well after 8 years. I noticed my browsers operate quicker with the extra memory. Have not tested it yet with video editing. Been waiting to add extra RAM at a reasonable price and for 21 bucks well worth it.

Received item on time and without any damage. Easy to install user itself and for me it’s worth it to buy.

The memory was installed in minutes and on re-booting the iMac, a noticeable - and good - difference in running applications. This memory was cheaper than others, which is always a "pause-button" when buying, but the proof is in the rebooting - and the iMac rebooted plus operated well.

Simple easy install. Delivered very quickly and I had my system upgraded the next day.
