Non-ECC memory/ram in 2017 iMac Pro

I have a 2017 iMac Pro with 32GB of RAM, Vega 64 and Xeon W-2170B (14-core). The only thing I’m missing is a bit more RAM and I was fortunate to aquire 128GB of non-ECC memory for free (see specs on Amazon “TEAMGROUP Elite DDR4 64GB Kit (2 x 32GB) 2666MHz (PC4-21300) CL19 Unbuffered Non-ECC 1.2V UDIMM 288 Pin”).

This is obviously non-ECC, unbuffered, unregistered memory vs. the existing 32GB I have in the iMac Pro but I can live without ECC memory.

Has anyone had success using non-ECC memory in the iMac Pro?

Sorry it won’t work reliably ;-{

I have a 2013 Mac Pro and I foolishly thought it would work, the problem is if you encounter any cell failures you can end up with a corrupted workpiece. I work on ultra large images every so often I would encounter image gremlins!

Got the correct RAM and no longer had any problems! I suspect you’ll also face that if you are working on large data sets.

I'm experimenting with processing large datasets using Apache Spark (which loads everything into memory) and also some distributed and in-memory database systems - not really image rendering stuff. I'd have to think there is a use case for large amounts of NON-ECC memory?

@smittycodes - Static data sets is about it. Anything that is under change puts things at risk.

FYI - Most of your corporate web servers are running with ECC RAM.

For reference here's some of the HP systems all of which use ECC RAM:

Proliant Bl460c Gen10 Blade Servers

Proliant Dl180 Gen10, Dl360 Gen10, Dl380 Gen10, Dl388 Gen10 Servers

Proliant Dx170r Gen10, Dx360 Gen10, Dx380 Gen10, Dx560 Gen10 Servers

Proliant Dl560 Gen10, Dl580 Gen10 Servers

Proliant Ml350 Gen10 Servers

Synergy 480 Compute Modules

Synergy 660 Compute Modules

Proliant Xl230k Servers

Proliant Apollo 2000 Xl170r, Xl190r, Apollo 4200, Apollo 4500 Xl450, Apollo 6500 Servers

So the only hard evidence I could find to support ECC was a 2009 study google did with DDR1 and DDR2 https://www.zdnet.com/article/dram-error...

It’s interesting read and it seems the motherboard plays a significant factor.
