Mine arrived. SK hynix on the label for both sticks. Model #HMA81GR7CJR8N-WM.
So Supermicro's stuff is likely going to be very similar, and probably cheaper depending on what kit you need: https://store.supermicro.com/8gb-ddr4-2933-mem-dr480l-hl01-er29.html
In my case, Supermicro would have been 7$ cheaper with their regular shipping. But since resellers like Supermicro use different brands for different capacities, I expect the same to be for OWC.

I bought 4x32gb dimms. In the 1st delivery, one was faulty and i had to send it back. Now is all good.
Why is everyone running to OWC? Nemix RAM is much cheaper and works like a charm in my 7,1. I got a 192GB kit and left the 32GB factory memory in it. Works perfectly.
A chunk of us are just used to ordering from them I think. They used to be one of the best places to get Mac-compatible RAM on price, with good customer service, and wouldn't go "but you put this in a Mac, we don't support that" like Crucial used to do back in the day. Things have changed a lot since 2010 or so, for sure.
If I was ordering more than 2x8GB, I'd probably be shopping around more myself.
How do you allocate the ram to the 12slots for the total 192GB kit + 32GB factory(total in 224GB)?
Should all ram be the same size in order to optimise the max speed？
I've been eyeing up OWC's 64GB RAM at over $729.00 for my Late 2015 iMac 27" (note this is their fastest version of RAM). That seems like a lot of money to invest in an older iMac. Newer iMac's, brought up to 64GB look less expensive on OWC's site. I wonder why? Are older models more difficult to find memory for?
I previously bumped my iMac to 32GB using OWC fastest RAM when I purchased the iMac. It has been reliable as far as I can tell. Though my iMac has rebooted itself while sleeping since the last two OS versions. I don't know if the RAM is the culprit, or some software running in the background. I'm conflicted on spending &729.00. But, I seem to be constantly running out of RAM while running Music, Safari, Messages, Mail, and Photos at the same time. I am running two additional 27" inch Dell monitors. Maybe, I've brought the RAM issue on by doing so?
I checked out the reviews of Nemix, and some of the reviews show issues with their RAM. Does anyone know if Nemix stands behind their RAM? Do they take returns for full refunds?

I've checked out their site. I'm not seeing a 64GB option. So I've contacted them about the possibility of that size RAM at 1867 MGZ which would match my current 32GB RAM purchased in 2015 from OWC. Thanks for the tip!

Memory prices usually follow a high-low-high price cycle.
- Initially high - when the new, faster, bigger or better technology is released
- Then low - when it's mainstream and economies of scale factor in
- Finally high - when a newer technology has become mainstream and economies of scale no longer apply
Wow, good price. I'm going to give them a call Monday just to double check it works in my Late 2015 iMac. Thanks for the help!!!
I bought 8 pcs of the 8GB version to fill all the 12 Mac Pro slots
