Corsair Mac memory 8GB DDR3L-1600MHz, 204-pin SODIMM (CMSA8GX3M1A1600C11)
I had 2 of this in my mac mini 2011 server, and run perfectly for 6 months , but now one memory has gone bad
Still runs, finds no error in mem test, but mac reboots from time to time... the other 8 is fine so i have just 8 now till decide what to get
No there is not.
Definitely check in your Finder > Preferences > New Finder windows show: (select something other than 'All My Files') even if you have already done this in the past, as it resets itself on its own behalf, because it's really poor software.
It's nothing malicious, though, just poor software. Try GNU/Linux.
Your model, like most Macs, supports memory interleaving, which means that paired memory may work better than single modules.
However, Apple's own guidelines for installing memory in iMacs make no mention of this, and the real-world effect may be minimal, (as mentioned in comments)
MacOS will try to use as much memory as it can. Having more RAM will improve performance, but using most of what you have is not in itself a bad thing. MacOS will make room, if it needs to.
This Apple support document tells you what the various attributes mean:
Wired Memory: Memory that can’t be compressed or paged out to your
startup drive, so it must ...
Judging from the stats you provide, it seems like it may be a CPU-related issue. Try to investigate this further to understand better if the issue is RAM or CPU related.
To determine CPU use, go to Activity Monitor and press cmd+2 to get the CPU usage graph. See if one CPU is peaking during these operations or if it is multiple CPUs.

Doesn't appear to be a direct way to do this. Part of the problem is that your changes to the NVRAM, if you were to clear it (nvram -c), will not take effect until after a reboot.
You could try this method which will perform a side-by-side diff of the contents of NVRAM prior to running a nvram -c.
$ sdiff <(nvram -xp) <(nvram -c &&...
The precious resource consumed by additional spaces is VRAM on your GPU. The higher the pixel count for the desktops, the quicker you’ll run out, but realistically you’ll get stopped by how many space thumbnails fit across the top of your monitors first.
Short answer: You won’t be causing a problem by opening more spaces, but you will eventually find a hard ...
