Newbie Question: If I want to edit videos, would it be better to have more RAM or more RAM DISK? I'm new to this PC building thing. Last night I upgraded from 16GB RAM to 32GB RAM. I made my RAM Disk 20GB so I can use that for scratch disk and still have 12GB for rendering and everything else but I feel like the more I dedicate to scratch, the less I have for rendering. Does it make a difference? Also, when I'm not editing or gaming does it hurt to have the RAM Disk on? I keep looking at my stats and it says that I'm using 80%+ of my RAM even though nothing is on the RAM Disk now and I'm just surfing the web. I don't want to wear my RAM out (if thats even possible).

A RAM disk is made using RAM i.e. if you have 16GB of DRAM and se up a 4GB RAMDisk, then you will only have 12GB of DRAM available for the system. When editing video, what many will do is create a RAM disk and copu the file (video) you will be working on so effectively the whole time you work with it it is entirely in DRAM...doing it this way (and depending on the size of the videos I'd want 32GB (maybe a 8-12 GB RAM drive) and then the rest will be 'system' DRAM

I see. The scratch disk thing wasn't fully making sense to me since to my knowledge I 'd only need it if I ran out of RAM, but using it in the way that you described makes sense. You're basically loading files that you want to work with into RAM.

I got 32GB of RAM for x-mas because it was so cheap so I was just looking for ways to put it to use other than for the aesthetics of having all of my slots full. My motherboard came with RAMDisk software and I'd never heard of it so I thought I'd play with it.

Thanks

Yep, say you have a 4 GB video file on your HD, you can copy that to your RAM drive , open your software, load the video from the RAMDrive then as you work on it (technically in DRAM) it will be constantly updating to the RAMDrive, doing auto saves to it etc, can save a lot of time 9Some RAM drive software also allows for auto saves to a hard drive, because if the rig crashes for whatever reason, you'll lose everything in the RAMDive. Most also have parameter so when you shut down it copies all to a regular hard drive and when you boot, it creates the RAMDrive anew and copies all yoru data from the hard drive to the RAMDrive for you (can slow down startup and shutdown a bit, but well worth it.
