Boost your system's performance with the 8GB JetRam DDR4 2666 MHz CL19 SO-DIMM Memory Module from Transcend. Delivering speeds up to 2666 MHz, this single-rank 1Gx8 DRAM module is a plug-and-play memory upgrade designed to improve your computer's start-up times, overall responsiveness, and ability to handle data-intensive applications. It is unbuffered, features a CAS latency of CL19, and works on systems with a 260-pin SO-DIMM slot and a DDR4-enabled chip. Moreover, the module's nominal voltage rating of only 1.2V not only ensures cooler operation, but also reduces the electrical load on the memory controller for power savings of up to 40% versus standard 1.5V memory modules.

Related Questions and Answers

Q: 1. Just bought a 2019 iMac 27”, 3.6 ghz, 8 core 9th generation Intel Core i9. Is this memory compatible? If not, what is for an upgrade to 64gb?

A: I just bought the 8-core, ninth generation as well. This memory set is perfect for spreading out your memory cost, as you can add a second 64GB (2 X 32GB) down the road to get a full 128GB machine. I know it’s probably overkill, but I’ve never before had 128GB. And, given hyper-threading, having extra memory for 16 virtual cores may help in multitasking, using all those cores more efficiently. 128GB total memory is what OWC has tested and verified for this machine (Apple says it tops out at 64GB). OWC says Apple didn’t have time to test the bigger SIMM cards, and that’s why they stop at 64GB. I’ve done this “2 X memory” on an older 8GB-Max Apple book, and it worked fine (giving me 16GB total).

Q: 2. Is this compatible with iMac (Retina 5K, 27-inch, 2017)?

A: If you are able to physically access the chip bay in your model, this chip model will be compatible.

Q: 3. Can the 3.0ghz 2019 iMac upgrade to 64gb of ram? Spec sheet says max ram is 32gb.

A: The iMac 21.5" 2019 model has a max RAM of 32GB.

Q: 4. will this memory work for a new Apple 27" iMac with Retina 5K Display (Mid 2020). [https://www.bhphotovideo.com/c/product/1582720-REG/apple_z0zx_mxwv_366_bh_imac_5k_27_3_6ghz_10_core.html]?

A: Yes, the OWC 128GB DDR4 2666 MHz SO-DIMM Memory Upgrade (4 x 32GB) BH #OW26664S128S is compatible with the iMac 27'' 2020.

Q: 5. Is it compatible with QNAP TVS-872XT 8-Bay NAS Enclosure?

A: We have not tested it, but the specs do match.

Q: 6. It would be desirable to add the list of computer models this memory upgrade is compatible with. For example, does it fit the latest iMac Pro?

A: For all compatible RAM for a particular model of machine, you can simply check the accessories section for that model and the compatible RAM will be there if the machine is user serviceable. This RAM chip can fit potentially thousands of models and the list is constantly growing. We will most likely be unable to show all possible compatibilities to one RAM chip as many of them are made to be agnostic between platforms and models.

Q: 7. Will this (128gb) work with the early 2019 27” iMac ?

A: Yes, this model is rated as compatible and the Mac is showing a maximum of 128GB of RAM.

Q: 8. Is this compatible with a late 2013 iMac 27inch? I already have 32gb of ram but was told it’s old and needed to swap out for new ones.

A: Sorry, no. The 2013 27" iMac will handle RAM with speeds PC3-12800 DDR3. This is a DDR4 RAM that you are asking about.

Q: 9. Is this compatible with the 2019, 3.7 GHz 6-Core Intel Core i5. It is currently running 2667 MHz DDR4?

A: Yes, this OWC 8GB DDR4 2666 MHz SO-DIMM Memory Upgrade (1 x 8GB) is compatible with the 2019 iMac.

Q: 10. Is that the right Memory RAM for iMac Retina 5k 27inch, 2019?

A: This RAM may not be compatible with that model of Mac.
