Out of RAM memory in ILLUSTRATOR CC, what should I do?

Question

Adobe

Hello! The thing is, recently in Illustrator CC a window appears saying that there is not enough RAM memory and at the same time it stops displaying objects with overlays of gradient fills or with 3d effects, and every time I launch the 3d settings window - effects, the preview option is lost and a message is displayed. in some cases it is not possible to export the file. There are about 50 GB of memory on disks.
In Google they write to demolish and reinstall with cleaning the registry. How can I clean the registry manually + some cleaning program ..?
I don’t understand the system at all, I don’t understand the registers either, I can only typeset books.
Help me please.
Re-pack of 6th Illustrator is installed on the computer.
The swap file for more than 2 GB was enough to manage 1.5 GB of the image. now does not turn over even elementary objects. Suspicion of clutter in the system.

Hm... and how much RAM do you have?
IMHO the simplest solution would be to fill the system with memory to the limit. Then you will stop worrying about the swap file and other nonsense.
Believe me, life with maximum RAM (well, and SSD to boot) is radically different from a system with a miserable 4GB of memory and an HDD. So if the physical memory is less than 8GB, I would boldly upgrade the hardware.
