Thread: Little to no Free Physical Memory??
Started 2 months, 3 weeks ago by Imogen
Hi, I just recently bought a desktop which came with Windows Vista Home Premium 64-bit. I have one question though.

Imogen Hi and welcomeo to vistax64 If you have 6 gigis and that much memory "disappears" its not normal. do you have any applications open like a browser, or windows index, or sidebar gadget,etc. Could you use the built in snipping tool (type snipping in search) to make a screenshot and use the attaching tool (shaped liked a paperclip) to upload the screenshot to us? thanks Ken...

Sulfuric is correct as usual. The ram is both being prefeched, and svchost.exe has grown to about 350mb but with your ram thats not a problem and completely normal. the prefetching is making you computer feel more responsive and svchost is a normal process. Hope this helps clear it up for you ]Ken

Great, many thanks to both of you for your answers. One last question though, why is svchost taking up that much RAM?

Unless I missed it and someone already mentioned this... Free Store Memory is the available memory locations, not actual physical memory. You can run out of it due to programs not exiting cleanly. Many don't. The only way I know of to reset that is to reboot. sometimes I have had to shut down, wait a minute or two, then boot back up. Suddenly, you have the ability to run programs on your computer again. Think of it as a list of database...
