Windows 10 computer with 8GB ram only using 4GB and then slowing down

Recommended Posts

I have an HP laptop with Windows 10 PRO , 64  bit

 

it has 8GB ram , but only uses 4GB and then slows to a crawl ,

 

much of the ram is used by FireFox  which seems to be 32bit , ( I always have  too many windows + tabs open)

 

How do I get FireFox or any other program to use the extra 4GB memoey

 

it has a 256 SSD , can I use some of the SSD as a Virtual hard drive ?

 

Thanks for your ideas

From Firefox's Menu Bar>Help>About Firefox .... will show you if you're using 32 or 64 bit Firefox.

If you really are using 32 bit, you'd be better off using 64 bit Firefox on a 64 bit operating system.

When you go to the Firefox website, it usually recognises your operating system and directs you to the correct 64 bit download.

That said, Firefox can be RAM-hungry, especially if using lots of Tabs, forcing you to restart it periodically.

So only 4 GB of the installed 8GB are recognised by Win 10? Or 8GB are recognised?

On a hardware level,

If PC is slow its because you have a bottleneck somewhere,

The component causing the bottleneck will be running at full capacity, 100%

If only 50% of RAM is being used then it's not RAM.

Time to check other components!

I've had serious slow down problems on a low end Windows 10 laptop and found this free program a magical fix --

I don't use the defrag though.

It includes a tool where you can free up RAM on the fly whenever you want called Performance Monitor.

When you say your pc is running slow what exactly do you mean, web pages taking ages to load or?

takes a long time to load  or update ,

freezes when I am writing an email on gmail website , but not if I write it on a desktop text file and cut and past it over ,

 

I am sure its Firefox and all the windows + tabs I have open ,  but since I have 3GB more memory I am trying to figure out how Firefox can access that memory ,

 

I have only had this laptop for 3-4 months since new  , and with an SSD should be real fast......

I had a similar problem on an Acer Netbook and it turned out to be the CPU slowing itself down to 5-10% of maximum clock speed as if it was overheating.

 

I installed some CPU and HD temp monitoring software and it shows no temperature issues so I suspect it's a mainboard problem and the $300 computer isn't worth the time to track it down and fix it.  That's after spending too many hours on fruitless Google searching.

 

Strangely, it only happened when I was downloading a bunch from the interweb.  So that Netbook is relegated to a traveling video player.

 

FYI, I found the issue using Windows Resource Monitor and watched the CPU % Maximum Frequency graph. It would start dropping from 110% and the computer locked up when it got down below 20%.

 

Edit, BTW:  Had a Dell laptop at work do the same and it was actually overheating.  Cleaned the dust bunnies out of the fan and it worked fine.  The Acer Netbook has no fan.

how do I find out what is in the " 3.3 GB cached "   and if its needed or I can delete it ?

 

that seems to be where much of the "missing" GB is hiding !

Suggest you open TASK MANAGER (by right-clicking the TaskBar and selecting "Task Manager"

>> Open the PERFORMANCE (tab) and select MEMORY.

 

Then click on the "Open Resource Monitor" link at the bottom of the Task Manager window.

>> Open the MEMORY (tab)

 

This will show you how your physical memory is currently being utilized.

...also, 'caching' usually refers to using fast memory (RAM) to store slow memory data (eg: Hard Drive data, or recently referenced OS or application code or data).  The operating system will utilize or release available RAM as needed.

FWIW, on my Windows 8.1 gaming pc if I try to launch Steam games while utorrent is running Windows will freak out and close the game and Steam (Steam sitting there downloading is not a problem).  Closing utorrent fixes the 'out of memory' error.  Funny thing is that it peaks up to 4.6 GB (out of 8) when that happens.  It's just Windows being Windows I guess.

Addendum:

 

I reenabled the swap partition and set it to a min/max of 4 GB and my problem seems to be resolved. Perhaps the OP should look into that?
