PC Setup for 15 Accounts / EvE Client needing more then 4 GB Ram

Im running into Issues whit the EvE Client when im Multiboxing EvE. I was able to run 14 Clients on one Grid whit a usage of 50 to 60% of my 64gb of Ram. Each client needing about 1gb to 2gb Max in August. Now this is the new World for me:


When i undocked in 1dq the Ram usage once rise for 1 client to 4.4gb wich froze my PC. Had to hard reset the PC to get it running again.

I don´t know when this started. I took a break starting on July through Oktober barely playing.

Is this now normal now or is this some kind of a new bug ? Or is my PC needed of a Upgrade ?

My Rig:
Intel 12900k (did some stresstesting no errors found max 80c)
Nvidia 3080TI (same as CPU max 90c)
4x 16gb Ram (2x Samsung 2x Corsair) @3200mhz
Eve Preview is also runing but whitout overlays, i only use it for Client shortcut
Numpad 1 is Client 1 and so on.

Edit: Client settings full Potato mode whit Weapon effects on (need to see whos shooting me )
and a Resolution at 2560x1440
