Is this memory upgrade compatible with other Mac models?

No, this memory upgrade is specifically designed for Mac Mini 2018, iMac 2019 and up, and not compatible with other Mac models.

Can I install this memory upgrade myself?

Yes, installation of this memory upgrade is user-friendly and can be done easily with basic computer knowledge.

Does this memory upgrade come with a warranty?

Yes, this memory upgrade comes with a warranty to ensure customer satisfaction and peace of mind.

Will this work on the 2019 iMac 3.6GHz 8-core 9th gen Intel Core i9?

Yes, you can mix the RAM on this model, but you need to put the new RAM in slots 1 & 2 or 3 & 4 to maintain a clock speed of 2666MHz. Mixing the RAM in alternate slots will slow it down to 2133MHz.

Will it work on 2020 iMac 27-inch Retina 5k display with 3.6GHz 10-core 10th generation Intel i9 processor?

Yes, it should work on that iMac model.

Will this memory work in the 2019 iMac w/Retina 5k?

Yes, it is compatible with the 2019 iMac model.

Is it compatible with Acer Predator 17?

Please look it up on Google to confirm compatibility.

Is this compatible with the brand new 2020 iMac w/ i7 processor?

Yes, it is compatible with the new iMac 2020 model.

Does it work with 21.5" iMac 2019 or just 27"?

Compatibility depends on the processor of the iMac. Only the 6-core processor from Apple supports 2666MHz. The 21.5" 2019 iMac would also require complete disassembly for installation, so we recommend professional help.

Why would one buy this over the less expensive Samsung?

OWC has a great track record and provides excellent customer support. While the Samsung memory may be equal in performance, OWC is a reliable choice.

Can this be used with the original 8GB RAM?

Yes, it is possible to upgrade from 8GB to 64GB by replacing the original memory in slots 1 and 3 with the new RAM. The original 8GB can then be installed in the empty slots (slot 0 and 2).
