i was wondering about a few things ..
CPU and MB already have and i want to do 5 4tb Red Plus drives in z2 and a single 8tb Purple plus
256nvme
1tb nvme buffer
What DDR should i run .mb and cpu support 128gb
but i dont see much info on what ecc memory or size i can use with my board
how much ram should i run
apps i plan to run are pi-hole ,frigate with coral dual edge , nextcloud and maybe a few more
Then you should be hounding the maker of the motherboard. A certified list of compatible memory is their job.
Here is asus’ qlv for ram:
To answer ‘how much’; depends on your budget. More is always nice, but maybe not to your wallet.
I’m also concerned what you mean by:
Do you mean SLOG, L2ARC, SVDEV, or something new entirely? Eitherway I can almost assure you than you don’t need it, or that it’d pit your pool at risk depending on what we’re talking about.
I have tried but there is only 2 manufacturers on there. And 16gb per lane. On there certified memory .. but when you look at there page it says it supports up to 128gb off ecc
Then you can either reach to Asus support for recommendations (likely useless), or just get something & try it 
I haven’t looked at these specific motherboard specs, but I wanted to mention If you’re getting higher capacities of ECC then you may need to use RDIMMs instead of plain unbuffered, too. So it might be best to reach out to support if you want 64 or 128 GB for their recommendations.
If they advertise the board as supporting up to 128 they need to be more helpful when it comes to modules to outfit it. Otherwise you have a case to get your money back.
No RDIMM with a W480 board! Core/Xeon W-1000 CPUs do not support it.
Would it hurt to just run non ecc since i cant really get any info
? waiting on asus to get back to me
I use this RAM on my W480 motherboard. I use 4 x 16GB sticks. W1270 CPU.
I run a 6 apps and a Win11 VM. 64GB has been plenty. Although if I had my time again I would choose 2x32GB to allow future expansion
Here’s the product page for your motherboard:
You should be able to tell from there the required RAM specs. More detail on the specs page:
Why on earth would you chose this board for a NAS?
