Are ram disk still around - make use of old ram

[a9249]

Hey guys, I'm building a new system and turning the old one into a nas - meaning i probally wont need all 24gb (6x4gb) sticks currently in there. I was wondering if there exists still some PCI Ram Disks like back in the ddr2 days. I edit 4k video and while 64gb of quad system memory with threadripper will more than likely handle everything i can throw at it... (for now *looks at 8k nervously*), I'd still like to get as much use out of my old ram sticks as I can, just 'cuz. A hyper fast scratch disk would be nice. 

 

Is there anything out there for this? 

 

Also, has anyone/ is anyone working on a standalone realtime asic 4k .265 render card yet?
