Windows 7 large cached memory

[User 11037]

Hi,

I have 16 GB of RAM, but when I open task manager and look at performance, only 412 MB of this is free and a staggering 12245 MB is 'cached'.

My understanding was that cached memory was used for 'superfetch', 'prefetch', etc, but I recently disabled these as I upgraded to an SSD and was lead to understand that superfetch etc. detrimented performance on SSD systems.

So why is so much memory still cached?

Thanks in advance

I have 16 as well.
14115 is cached...
0 free.

Cached memory is good, as unused memory is wasted memory in my opinion. I didn't think *all* cached memory was used for superfetch, but I could be wrong.
