Force windows to use more RAM

  cemopolat 07:14 27 Mar 14


I have assigned more than enough RAM for a virtual machine (W7 64 bit guest in Vmware Workstation); 32 GB.

There is no problem but sometimes I notice too much disk activity and CPU usage because of some "heavy" applications.

I wonder if there is a way to force Windows use more RAM to cache applications or related files etc..

  • I tried to decrease swap memory (even disabled) but didn't help much.

  • I checked prefetch service and it is running

  • I increased min. memory for SQL server and other applications' spesific settings, but that didn't help too much either

I appreciate any ideas like some registry settings, fine tunings to maximize RAM usage and minimize disk usage etc.. Or maybe more "low level" settings in registry like disk read/write parameters, cache/block sizes..

Thanks in advance..

I forgot to mention average memory usage; It is generally 30% and max 60%. I have never seen it goes more than 60% even under heavy load. That is why I am trying to force Windows to use more RAM and less disk.

It's a good idea. I also notice that PC using maximum of 60% of RAM. It would be better if i could force PC to use more memory. But i don't have idea how to employ it. So i could only add few GB of more RAM in my PC.
