Solved Windows 8 low on memory

February 26, 2013 at 17:47:18
Specs: Windows 8
I thought that Windows 8 was supposed to be better with memory than Windows 7. So far, that is not my experience.

When I boot up my brand new laptop (Samsung NP550P5C-S03CA Intel Core i5 3210M 8GB 1TB ) , the Task Manager Performance tab tells me that I have:

8.0 Gb of DDR3 available
of this:

3.7GB is in use, leaving 4.2GB available

3.5/25.9 GB is committed and 1.4GB is cached.

162Mb paged pool, 2.4GB non-paged.

I then go to the Details tab, and I add up the Memory used by all the processes. It comes to about 300Mb. That is 0.3GB. So what is using up the other 3.4GB of memory???

I then load up a bunch of programs that I use concurrently - notably Firefox (with about 30 tabs), Chrome, Thunderbird, Notepad++, Filezilla and my memory consumption goes up to 4.4GB. That seems about right.

I then work on it for a number of days, hibernating in-between, and I start to get notices that I am running low of memory. The performance tab says I am using 90% or more of my memory. The committed has gone up to 31GB. But if I add up the memory usage listed in the Details tab, it comes to only about 1800MB (I notice that Firefox has gone up to about 1300MB)

So, again, where has all my memory gone?

If I then close all the programs, it doesn't help. The details tab shows little running, yet the Performance tab shows I am still out of memory?

What is using up all my memory?

The only thing that clears it, is to do a restart. Which brings us back to the top of the loop, with the same initial question - what is using up over 4GB of my memory?

I never had these problems with windows 7.

As a sidenote, Win 8 also seems to be very unstable. Frequently getting programs not responding and crashing, including Windows Explorer, which seems to have to reload itself frequently.

Oh, and my wifi connection keeps dying and then I have to run the troubleshooter to get it all running again (my wife has that same problem on her brand new Acer).

So, what gives? How do I get my new laptop to work as fast as my 4 year old Sony Vaio with Win 7 and lower specs?

Anyone got any ideas? Or is this normal for windows 8?

Firefox has, in the past, been notorious for memory leaks. If Windows was specific about the process that was using too much memory then it was probably correct.

Memory management in newer versions of Windows is extremely sophisticated and it is not really meaningful to look at unused memory. Other than ill-behaved programs, Windows can quite happily move memory about and use spare memory for various system caches that speed the system up.

You've paid for that RAM, so why would you want it to sit there unused? But obviously messages like this about a specific program are different. Perhaps it's time to upgrade Firefox or even consider using a different browser.

Your numbers show 2.4 GB non-paged pool. Is this correct?
If so this is far beyond what a reasonable value would be. This could be caused by a process but more likely by a bad device driver or malware.

Adding up the memory usage of processes rarely provides meaningful information and should be avoided. In most cases it will only result in confusion. This isn't even the full memory usage of a process and there are major users of memory other than processes.

That is indeed what it showed, after a restart. If it were caused by a bad driver or malware, how would I identify that?

Interestingly, this is my second laptop. the first one went back to the store because within 3 days, while I was still trying to install stuff, it became completely unresponsive with massive memory usage and 100% disk thrashing. As best I could determine, it had something to do with the norton bloatware, but I was completely unable to install it.

This time I uninstalled the Norton before i did anything else, and switched on the Windows Defender instead, though, for a while, I thought it was going to do the same thing again. However once Norton was gone, it did settle down.

But still with this high memory usage.

Very odd.

Well, I have not faced any kind of problem related to low memory. I am using 100% of the memory. I think it might be some other issue.

This whole issue started because Windows told me I had to shut down Firefox as it was using too much memory. That is when I went to have a look at what memory was being used by what. At that time Firefox was using about 1400Mb, but overall memory usage was above 90% as I said above.

Download, install and run MalwareBytes freebie:

This often finds what AV's miss. If it finds anything of any consequence it will prove that your issues are virus related.

Always pop back and let us know the outcome - thanks
