I have been having this issue as well and have seen it go as high as 700mb+ even when idled. its insane i have found NOTHING ANY where on how to actually resolve this issue.

i use a Naga Trinity, Blackwidow v3 and Blackshark v2 pro’s.

i wish i wasn’t so used to the naga or i would have given up and gotten rid of all my razer products.

instead everytime i turn on my pc i have to close synapse, end all synapse related tasks, end gamemanagerservice task, and leave razer central tasks running as they dont use up any resources.

my rbg effects doesnt work but idc about lights if its at the cost of a never ending buildup of ram usage. i just turn them off. my devices all seem to still work as they did before.

based on the years of posts i’ve seen about this with no fixes and no support help i will getting rid of my razer equipment as soon as i can afford it.

i would suggest you do the same.
