Exclamation Ram always cached...
Anyone have any clue why my Ram (12 gb) is pretty much always all Cached? I try and play games and stuff and they're laggy because my ram always is like this:

Total: 12279
Cached: 9090
Available: 9090
Free: 36

173 views and still no reply.. Well, good. At least I'm not the only one that doesn't know how to fix this issue.

Windows handles memory just fine. Caching has nothing to do with any lags you are experiencing. Chances are that around 9 GB of that memory will be unused. Caching speeds things up which is why it is used. It may speed things up if you reduced the amount of RAM. It might be worth a try since some boards use a slower addressing scheme for larger amounts of RAM. In any case, that much RAM will slow down booting, shutdown, and hibernation considerably. If you have no specific use for it (RAMdisks, virtual machines), it is pretty much a millstone around your neck.

Thanks for the reply.

I always thought the more ram, the faster everything.. I have a gaming rig.. So people said get at least 12gb..

And what explains the fact I have 0 free ram and that's when my machine starts to lag? Especially noticeable when playing games.

You never have 0 free RAM, despite what the Task Manager may say. Cached RAM is always available for use if needed.

How much RAM is being used on your machine on average in the memory graph or the % in the status bar?

% in the status bar - About 2 GB when my game is running.
