And my iMac has two more slots, so I can eventually buy 2 more and have 128gb total. Wow!

Other PCs that I confirmed:
・ASRock DeskMini 310
・ASRock DeskMini A300
・Dell OptiPlex 7060 Micro
・hp EliteDesk 800 G4 DM


I was a bit curious if 128GB of ram would work on our new 2019 iMac (i9 3.5Ghz 8-core processor). It's working like a charm as I type this very review.
By the way, if you are in the process of going deep down the rabbit hole of RAM technology, then I'll save you the time from researching ECC RAM. You don't need it. Its functional benefits are for servers. The iMac Pro uses 288 Pin ECC RAM modules (same as servers), whereas the iMac uses standard desktop 260 Pin modules. I vote that was partly for marketing purposes, perhaps akin to a car manufacture using titanium lug nuts for the wheels.

TL:DR
- Its time consuming to get to the RAM in this computer
- Make sure everything is working before putting this back together
- Check that your fan is spinning (0rpm is no good, this computer always has an idle speed)
- Macs Fan Control is a free app that will help you check your fan is working properly
After all is said and done this RAM is working great in both slots for a total of 64GB, but I did have quite a bit of troubleshooting before everything was working well. On my first attempt of installing I took the whole machine apart, replaced with new ram in both slots, put everything back together and...no boot. This computer can take nearly 10min to put back together with all its tiny screws and connectors (im looking at you impossibly small and poorly placed wifi antenna!). I would highly recommend leaving the computer half built and testing a boot before reassembly. I left off the ram metal shielding, fan, and wifi, and was able to boot without problem. Basically, install the ram and only replug the large logic board power cable and the tiny 2pin cable nearby and try to boot. After all is said and done I needed to try x6 boots before I was able to successfully rebuild. KEEP IN MIND, this little computer runs HOT FAST, so when boot checking, simply get into the OS, make sure you see the ram in your System Report, and power back down.
- 1st attempt: Removed OEM RAM and replaced with x2 samsung = no boot
(had already put the whole computer back together = MISTAKE)
- 2nd: Took computer apart again, put OEM RAM back in = successful boot
- 3rd: Left computer mostly disassembled and installed x1 32GB stick = successful boot
- 4th: Installed 2nd 32GB stick = successful boot
- 5th: Re-installed all pieces except bottom metal shielding (aka wifi) = successful, but no fan
- 6th: Pulled the fan back out, and its tiny connector had pulled up slightly during instal and only had 2 of the 4 pins connected. Pressed down on the connector and = fully successful boot
- Then reinstalled all components.
I hope this helps save any future DIY'ers a little bit of time. All in all, took me about 45min to get everything settled in with all the troubleshooting. If I were rebuilding this entire machine every-time it would have easily taken 2+hours and would have been possibly frustrating enough to give up and go with a trusted third party option.


It's about time that 32gb SO-DIMM's were available at a reasonable price.
Purchased from seller "Dataram".


So the memory works, BUT when combined with the factory RAM only runs at 2133 instead of 2166mhz. I ran some benchmarks, and the 72gb was faster than my 8gb configuration. I then played with all combinations in the memory banks, couldn’t get the memory to run at top speed, so I removed the factory RAM and tried JUST the 64gb of Samsung RAM. Sure enough, the speed shot back up to 2166mhz, AND the benchmarks showed this as the best performing setup by a long shot.
The specifics (Geekbench 5 multi core, i5 processor 3.3Ghz version):
- 8GB OEM: 5904
- 72GB OEM + Samsung: 6481
- 64GB Samsung only: 6768
So I give the RAM 4 stars ... would have been 5 if the memory did not slow down when combined with the OEM Apple RAM.
