Windows 7 Memory Usage Cache Size

[nschoonover]

I have noticed protools will complain about using too much memory and occasionally crash when I set my Cache Size to 7GB or higher in Playback Engine. My system has 16 GB of memory and is usually hovering around 10-12GB or memory usage when this problem occurs. When I set my Cache Size to 6GB, the problem goes away. Anyone else experience this or know of a fix to allow protools to utilize more of my available memory?

Protools: 12.3.1
OS: Windows 7
CPU: i5 6500
Memory: 16GB DDR4
GPU: GTX 560 Ti
OS Drive: 124GB Solid State
Session Drive: Network Share (SMB)

I too have 16gb ram. You do not need to set the cache size that high. Only set it to cover the size of the session. Mine sits at 3gb which is usually more than enough. If you want to use 7gb you will have to up your ram to 24gb. Don't forget, your system and the programmes you are running require ram to function.

Thanks for the response. Maybe I am not seeing correct memory usage from windows. I am seeing 8-6 gb of free memory reported by the resource monitor and assuming this is memory that can be used by protools.

Don't forget that the memory you allocate to the cache is not available for anything else. So if you make the cache 7gb you only have 9gb available to run PT, the computer o/s, plug-ins, and VIs, etc. So it soon gets eaten up. The 8-6gb you see in the resource monitor is whats available to run everything else, not just PT.
