Hey :-)
What do you think is the ideal RAM size for a motherboard running nvOC?

Here is a look at how much it uses one one of my rigs with 7 1070's:

Code:

m1@Miner1:~$ free
total used free shared buff/cache available
Mem: 8107204 1632364 5565128 42012 909712 6055112

As you can see, I have 8 Gb but it uses less than 2 in REMOTE (no local display). I tend to buy HW that I can re-purpose in the event that mining goes south, so I recommend running a single 8 Gb stick per mining host. I typically purchase them as a 16 Gb "kit" with 2 8 GB DIMMs. Clearly, you could go as low as 4 with no issues but I have no use for DIMMs that small outside of mining.

I think it depends on card counts and types.
As stubo said, I think 4Gb is enough too.

1x 1070 + 2x 1060 test rig:
