Edit: I apologize if this thread/question is in the wrong place.

Background: Hey all. I recently got into multiboxing WoW and overall I have had good experiences. I am currently trying to solve the main issue I have been having the past week or so. I am trying to 8-box WoW along with having discord and 1 stream/vod/video/music tab open in my browser.

Hardware:

CPU: Ryzen 7 2700x

GPU: EVGA Geforce GTX 1080

RAM: 32GB G.Skill Ripjaws V DDR4 2400

Motherboard: Asus ROG Strix B350


Problem: My main issue that I am encountering is when I reach about 80% RAM usage of my 32 GB I get an error from WoW that I have run out of memory, when, according to the math I still have around 4-5GB of RAM to use, and if it did utilize that remaining RAM I am confident that the issue would be resolved. Is there anyway you could think of to solve this issue, ideally by having it utilize up to 95-98% of my RAM before crashing?

Conclusion: I am open to any ideas at this point, if I can solve this issue I believe everything else can be overcome relatively easily. Thank you for taking the time to read/respond to this thread and have a great day!
