I'm running a 860 i7 chip with 8GB ripsaw RAM

Windows task manager says my cpu usage is 4%, but my physical memory is up @ 75%

All i'm doing is surfing the net & DLin some music here & here


WTF is going off.? Should I be worried.?
 
I get that sometimes. If I'm watching a HD film on VLC it seems to gradually increase as the film goes on until it reaches 98% and my PC slows to a crawl. Normally I kill the process and reopen the program and it fixes it.

How much is cached memory and free memory in windows task manager? Imo Windows love to use the ram for caching
 
Here is a screen shot of the processes

your firefox is using an unusually large amount, Do you have a lot of tabs open or your streaming video on it or something?

Seems like your background processes are only using about 1400MB or 1.4GB of ram out of 8GB which is still only 17.5% ram usage.

You need to take a screenshot of memoy figures by going to performance tab and noting how much free, available and cache memory you have.

Physical memory usage = Total memory - Available memory

Now it may be a lot of ram has been taken up by windows to store cached data.
 
I've defo got 8GB

I've got 5 firefox windows open, with 36 tabs in use. lol

Here is a screenshot off the graph chart

You can see that almost 3GB of ram is used just to store cache data by windows. You need to do something called cache flushing in order to terminate plenty of cached data so more ram is freed up. However if you run any game, then ram will be available for ingame usage.

Can you click on resource monitor button and then click on memory tab and then take a screenshot. It is most probable that windows has used up lots of memory for it's own usage.
 
Firefox uses upto 2gb for me sometimes, I switched to chrome which is less of a hog

To show all memory it needs to have the commit size column enabled also

As I suspected over 5GB of ram is being used by Windows operating system. This includes the ram usage of about 1.5GB by background processes as mentioned before and about 3GB is being used to store cached data (standby + modified) leaving only 23MB of ram free.

If you click on the name of memories, it gives you description of what each memory is. Basically they are just different names to imply physical ram usage for different purposes.

Normally afaik Windows7 uses somewhere between 700MB to 1.2GB for it's own operation. So I don't know why it is using 2.5-3GB of extra ram even if you exclude the 1.5GB of ram usage for background processes and device drivers.

Right, I did the cache flush, emptied firefoxes recent history & then turned off the machine.
Now I've fired it back up, this is the readings >

Looks like it may of worked
 
It's a known issue with FireFox, if you go opening up lots of tabs it will ramp up its memory usage considerably. It doesn't seem to reuse instances of objects already declared but instead seems to declare then again for each instance of tab you open. Naturally this creates lots of instances of objects, all of which take up some memory. It just piles on.

Not sure if FireFox 4 still does it, was definitely the case up to FireFox 3.6 from what I found.

Chrome is IMHO the best browser out there thus far, keep IE for the odd pages that have bugs on them and their forms don't work unless you run them on IE.
