Windows 7: Limit RAM Cache?


22 Feb 2013   #31

Windows 7 Home Premium x64
 
 

I'm back here again, exactly one year later with the same problem. 0mb of RAM is free, and over 4,500 cached.

Following applications are open:
  • Firefox 19.0
  • iTunes 11.0.1
  • Teamspeak 3.0.9
  • Windows Task Manager
  • World of Tanks Client (Video Game)
I'm having difficulty watching YouTube videos, playing video games, and even browsing the web at times. Windows 7 is managing my Physical Memory very poorly, and I'm not sure if there is any new methods to avoid this problem?

Ignore the "Free" field it is meaningless. The only important value is "Available"
Open Resource Monitor and give us a screen shot of the Memory tab with the Physical Memory pane open. While you are running your game.

Available memory doesn't become relevant until it becomes Free. Which is my issue.

Available is free RAM! It signifies what RAM is available to applications without having to page anything out. The standby (cache) memory is not your problem. Something else is involved here. Which is why I asked you for a screen shot of the problem area which you have yet to provide.

"Available" includes "Free" and "Standby."

Unless you managed to come across some crazy Windows 7 bug that no one knows about, your alleged problem is not because of the Standy SuperFetch cache, even if you mistakenly think it is.

There is a bug. The Bug is that "Free" and "available" should be transparrent to a running program - BUT DO NOT SEEM TO BE!!11!1!!!!11!!
Look at the last 2 posts in the following thread:
how do you shut off standby memory in windows 7 - Microsoft Community
Quote of Anooshiravan Ahmadi:
"Your problem is that some of the games are designed to look at “free memory” to calculate the available memory. Many windows applications are looking correctly to “available pool” to allocate memory, but some games look at the “free memory”, it is simply a programmer’s choice.
Answer to your question:
Please download RamMap from Sysinternals:
RAMMap
And from the menu “empty standby memory” -> you will see in task manager that all cached memory is added to the free pool. Then you can start your game without having to restart Windows.
Also there is a tool called EmptyStandbyList.exe (please google for it) that does the same action from command line, so you can schedule it for instance."

And one other quote from that thread, Gnostic1977:
"OMG Thank you. RamMap solved the problem for me. memu Empty - Empty standby list
Thank you.
I have been getting the same run around the earlier posters got from people.
I know what standby memory is, the definitions, its use, how it is used and the theory behind "standby memory."
However somewhere in the development of MicroSoft's code the "Standby Memory" evolved into used memory that is not available / free for use.
My system (8G ram) has been thrashing with 100K to 3 meg of "free ram" and "standby memory" has been acting like a memory leak that is constantly chewing up more and more memory.
This problem has keep my company using XP as this sort of issue was not a problem with XP."

Unfortunately, yes, this is a problem, and I flush the "Cached" pool myself with RAMMap, when Windows 7 says that it is running out of memory.

EDIT: I have all sorts of prefetch disabled, both in services and REGEDIT... - does seem to help
