Hi all,

I watched this video

It seems that I can save money if I choose to buy my own DDR4 and add into the 2019 iMac 27" 5k model.

I plan to buy this (though it could be 2020 model by Jan 2020)

27-inch iMac with Retina 5K display (latest as per Apple's website)
- 3.6GHz 8-core 9th-generation Intel Core i9 processor, Turbo Boost up to 5.0GHz
- 8 GB 2666MHz DDR4 memory
- Radeon Pro Vega 48 with 8GB of HBM2 memory
- 2TB SSD storage
- Magic Mouse 2

Really can add the memory manually? Plus can I buy any DDR4 memory or have to be compatible to Mac ones? Any recommended memory which I can buy in Klang valley or lowyat plaza?

Thanks.

have you tried personally? no side effects adding own memory? do you have recommendations which memory brand to buy that's compatible?

I see, so it makes sense I get only 8GB RAM for the iMac 2019. Then buy a new set of 64GB RAM separately with same chipset/density/rated speeds and manually plucked them in.. then it will work just fine? I presume so. Thanks in advance.

Thanks for sharing.

I guess I just need to buy 2 pieces of that from Amazon to get 64GB. I think 128GB is kinda over killed. What do you use for?

Also why didn't you upgrade to catalina OS? Kinda curious.

It seems catalina has issues with this Samsung memory. Hmm...
