24GB vs 12GB RAM
Worth it?
I grade 2k film scans, RED (with RedRocket), and Alexa. Currently using a Cubix with 2x GTX 480’s flashed for Mac (and RedRocket is in there too), with a 24TB SAS (600MB/s read). Currently we only have 6GB which seems to be coping OK for short form stuff. Definitely upgrading to 12GB but is it worth going all out and getting 24GB? Will Resolve even make use of it!? Future workflows might include 4K finishing / 4K scans. What exactly would be sped up/improved?
The machine is also used for on-lining in FCP and some VFX in Shake.
Thanks!

Depends where you are at.
In europe memory is cheap. 24 gig is around 240 €
I would go for 24 if money is not limiting here.
Specially for other apps.—

If you are playing back 4K DPX scans, the read speed of 600MB/s would be an issue… I think RAM often comes into play with longer and more complicated projects but is a cheap and simple upgrade… I notice a significant difference between 12 and 24 on two workstations I use frequently on feature-length projects.

[Toby Tomkins] “Will Resolve even make use of it!?”
Yes it will. As your projects grow in size, it will delay the onset of the “Resolve is running out of memory” warning. The more active source media, stills, etc., that you have in the tent, the more memory you will need.

Playing back 4K at the most common frame sizes requires approximately 1.2 GB per second, not 600MB. It’s 4x the data of 2K, not twice.

Right, Toby’s current read speed of 600 MB/s would be an issue.

Kingston has 8gb dimms for MacPro.
24 gb at least for a setup like this is a no brainer. -
Thanks all. I’m aware of the transfer bottleneck for 4K. I’m still grading in 1080p timelines though so resolves caching with 1080p DPX is very handy (-; I can wait for the 4K master renders/output when I do them.
Thanks again.
