Ram fills all the slots so the CPU's are not being starved. Use a big chunk of it for a ram disc.
Starved of what though? In my years of running 3d programs, GPU renderers, AE, PPRo, Avid, Protools, etc I've yet to wish to have had more than 32gb of ram (OK, AE will take as much as you let it, and sometimes more, but for RAM previews and such) With the advent of M.2 PCIe drives are RAM disks still a thing that is needed? Sorry, not trying to be obtuse or anything, I am just really trying to envision the use of that much RAM outside of virtualization or server usage.
I remember using RAM disks for AE previews waaaayyyy back in the day. It was one of the biggest leaps forward at that point, but RAM was so silly expensive compared to today, jumping from 512mb to 2gb in our AVID machine cost us damn near 6 months rent on our office space!
I could load pretty much every KS project I've worked on in the past 2 months into RAM on that machine. Or open a couple dozen Chrome browser tabs:)
Still, 617fps though....
