12.7 - Memory

Any reason why 12.7 would say it's using %50 of the Memory Available?
I've tried all the cache settings..

This is on a test machine, running 10.12.2.. 2010 27inch iMac with 8GB of Ram.

The session is new and completely blank.

I am going to go out on a limb here and say: That is because you only have 8 gig of ram. If it is only using 50% then at least you have some left.

PT 12.7 uses disk cache and 8GB memory simply will be not enough for a decent performance in the long run. It´s all 64bit now, the OS, Pro Tools etc.
You want 16GB memory at the least for PT12.7 even if the official requirement says 8GB minimum.

I have 16GB in my i7 Quad MBP and still cannot get loaded whole sessions into the Ram by disk cache even if those sessions are only small to mid sized,
not even large ones.

Also check out if there are other programs/applications running in the background but 8GB will be not enough for PT12.7 anyway finally.

Yah, thats what I figured.. 12.5 did not exhibit the same behaviour on the same machine though, so I thought I'd ask.

Disk Cache - you have to turn it on - it is not on by Default - and you can set it to something smaller like 256,MB 512MB, 1Gb ..

To add to others' comments, memory being used is a good thing. If it's unused, it's being wasted. PT & any modern OS will preemptively & speculatively load things (code & data) you *might* need into memory. This way they're quickly available. If memory fills up and something else must be loaded, PT / the OS will move unnecessary/unused things out of RAM & onto disk, while keeping as many in-use resources as possible loaded into RAM.

Also, contrary to others' opinions, I have gotten by fine with 8gb, using basically no VIs but plenty of tracks (up to 35 I think) & a "normal" array of plugins — i.e. lots of lightweight eqs & comps (mcdsp), a couple heavyweight reverbs (lex) & delays (soundtoys), & a welterweight limiter (ML4000). YMMV but I wouldn't worry about what the memory meter says unless you actually have problems, most likely in the form of slowdowns while things are written to & read from disk.
