  • My Imac 2020 intel runs quick & very smooth
Size: 128GB KIT(4x32GB)
Recently, I order a 128 gb Ram (4-32gb) from an undisclosed company with the same advertisement as Timetec but I had to returned them because they did not work on my Imac. After waiting approximately 20 minutes (after installation) my Imac failed several times to come on. Then I ordered the Timetec 128 gb Ram (4-32gb), installed it and immediately my Imac came on, load up and started operating with unbelievable quickness & smoothness! Thanks Timetec, you made me one satisfied customer!!! ... show more

  • Waited To Long To Do This!
Size: 32GB KIT(2x16GB)
Worked Great with my iMac 2019 27in. 5K. Going from stock 8GB to 32GB gave me peace of mind and noticeable performance. At first, I only replace the stock 8GB memory and installed the (2 X 16) GB Ram into those slots to just get 32GB. I watched some YouTube videos to use existing memory to get max. speed performance. - ** 4-4-16-16 worked for me a total of 40GB with 2667MHz. Overall, my only regret is that I didn't do it sooner. ... show more

  • Handled The 7 hour Memtest like a pro on my 2019 iMac 21.5 with an upgraded i9 9900 2-2TB SSD
Size: 32GB KIT(2x16GB)
After initially choosing to go with the widely recommended and twice as expensive OWC memory initially for my 2019 iMac with an upgraded 2tb ssd and 2tb m2 and the Intel i3 replaced with an Intel i9 9900. I wanted limited risk and bulletproof. After crashes and freezes and lots and lots of troubleshooting I finally figured out that my intial set of memory was kicking errors. Long story short I requested my first replacement set 4 months ago and now I have my 4th set on the way from that other company. Meanwhile, after three sets of competitor ram kicked out errors I decided I was done with that. After overanalying between these and others and went with Timetec for Mac. First things first I popped them in, reset the PRAM and SMC then fired up the rugged 6+ hour 14 test MEMTEST86+ overnight that had caused the OWC sticks to buckle over and over. When I woke up in the AM these had passed with 0 errors, show up ok in system settings and function BETTER than the OWC that came highly recommended (The OWC registered 14, 400, and 77 errors over three sets). If you're on a budget or just want something that you know will work with your Intel iMAC buy these, save your self cash, seat them correctly, reset PRAM and live happily ever... well it's technology, so enjoy a few solid years with your faster computer! Oh, and if you made it this far and are wondering, yes I upgraded the processor on my 2019 iMAC 21.5, as well as both hard drives and upgraded memory. I also tossed in a laptop fan for extra air movement. Yes, it all works just fine without issues. It gets warm when I'm working it hard, but I have TG Pro controlling fans and all seems to be fine. Also, I'm still waiting on my fourth replacement set to arrive going on week . I think it's been over three weeks since I sent back the last faulty set. Thank you Timetec for helping me out of that nightmare. ... show more

  • So easy!
Size: 64GB KIT(4x16GB)
I have a 2019 iMac with 8GB memory and operating with Monterey. After having serious performance issues, I decided to upgrade to 64GB. I can't believe how easy it was to install the memory. My iMac gave me no issues with recognizing the new memory cards. And the lags and performance issues are gone. I am only kicking myself for not having done this sooner! ... show more

  • 2020 iMac 27" now with 40GB RAM
Size: 32GB KIT(2x16GB)
I purchased this to add to the existing 8GB of RAM installed in a 2020 iMac 27" (i7, 512GB SSD) I purchased a few days ago. The RAM was installed per Apple's prescribed arrangement (Slots 1 and 2 with this 16GB x 2 and 3 and 4 with the original 4GB x 2). After powering on the iMac with the new RAM installed, it takes ~30 seconds for the system to check it before it will begin booting - during that time, the screen will remain black and it will appear that pushing the power button did nothing to turn on the system. Give it a moment. After booting into Big Sur, I checked the RAM to see if this combination was running at full clock speed. Good to go: 40 GB @ 2667 MHz. This has greatly improved performance of the computer. I use Parallels Virtual Machine every day for work. My former main system was a 2020 MacBook Pro 16" i9 with 16GB of RAM. This worked great but the iMac now with 40 GB of RAM allows me to avail to the VMs a lot more memory. I'm very pleased with the iMac now that it has the RAM upgrade. Time will tell how reliable it is but being Hynix, I doubt there will be any issues. For anyone interested in the performance difference between the iMac 27" with upgraded 8-core i7 (desktop) versus the 16" MacBook with 8-core i9 (mobile), the iMac is faster. I haven't bothered yet with benchmark tests to quantify the difference. I can tell just from using programs I'm intimately familiar with that it takes less time and GUIs have a little extra pep in their step. Fusion360 renders significantly quicker, Parallels VMs boot and run even faster - and that isn't to say the MacBook does these jobs poorly. I will save use of the MacBook for when I have to work in the field. UPDATE: I just purchased an additional 32GB (16GB x 2) kit to replace the 4GBx2 that remained, taking it up to a total of 64B. This RAM (new and old) has proven rock solid in every day, strenuous use. I would definitely recommend it for iMac owners. ... show more

  • Just what I needed!!!
Size: 32GB KIT(2x16GB)
This was a perfect fit... I installed 32gb ram DDR4 while I changed out my NVME in a iMac 2019 3.7 ghz 6-core Intel i5. Remember this is about the processing of running multiple programs simultaneously than speed when upgrading your memory. If you need speed consider upgrading your storage and/or processor. I've had no problems with any lagging and can open multiple programs at one time. DDR4 is NOT interchangeable with DDR3 or any other memory ... show more

I recently upgraded my 27" iMac (2020) with the Timetec 64GB KIT(4x16GB) Compatible for Apple DDR4 2666MHz. This has exceeded my expectations in every use case thus far and is really promising. The performance difference is remarkable from the 16GB stock configuration.

Overall, I am very much satisfied as I look forward to seeing what this new system is capable of! ... show more
