Windows only able to use 4GB on 8GB RAM

[fuzedzn]

I was doing some testing to see how much CPU and GPU usage Simcity was using as a troubleshooting idea in another post when I noticed Task Manager was detecting only 4GB of ram..

i then ended the game and went into system settings in windows and it says "8GB (3.98GB usable)

 

I've not changed anything in the bios and as far as i could guess the RAM and Mobo must be working correctly to be able to detect the 8GB.

Im using Windows 7 64Bit and the rest of my specs are in my signature

 

Help needed!.

Are you sure you have 64 bit?

Have you tried a clean install of Windows?

[LogicDeifying]

What does your BIOS say?

Let's not jump to conclusions...

Have you tried a clean install of Windows?

This is practically a fresh install

 

What does your BIOS say?

Not gone to the bios yet.. Don't want to leave windows unless something happens

Try booting with one stick in at a time to test if either of them is dead.

Maybe windows has reserverd 4GB for Hardware, or it's simply in Standby

[Bloodyvalley]

You're probably running RAM-intensive programs, that's why.

[AGGELOS_970]

Maybe you have installed a software that uses RAM to cache. Like a software for an SSD or HDD.

Or as Bloodyvalley stated.

I'm pretty much sure nothing will happen...

right click your taskbar, start taskmanager and go to the performance tab.. Now use any bench program that will fill all the ram.. See how much it
"actually" uses.

 

windows 64bit sometimes says it can only use 4gb when it's actually working fine...

Stayed around 3.14, Ran simcity, that maxed a 3.8gb.

Not installed anything for the SSD or HDD.. not installed anything new in the last few days.

That wouldn't make windows say its unusable at all though i shouldn't of thought.

A friend of mine said that... but how would i stop it doing that?

Open task manager -> resource manager and check if its actually standby/resverved

[Bloodyvalley]

Open task manager -> resource manager and check if its actually standby/resverved

Actually it's in Performance < Ressource Manage < RAM

[LOLPhilips]

open msconfig, second bar, "advanced options" make sure it says maximum amount of memory (might still not show 8gb) but might aswell try

 

I'm dutch so sorry but I only have a dutch example:

So i checked... Looks like its reserved. http://gyazo.com/fae997891e43d79219490138200c4b35

I have max mem unchecked.. shouldn't affect it.

well check it and see if you can select 8gigs.

If not try a bios update.. If that doesn't work reseat the sticks.

When checked it goes right to 8GB... And like i said.. Windows is saying i have  8GB but as my post above said.. its being reserved.

No... just no. That isn't how it works.

I'm using windows 7 so things look different

[Dr3nz4r]

for reserved ram :

 

msconfig.exe -> start up -> Advanced Options -> Check max ram and set it to 8Gigs -> reboot

 

If this does fix the error, you're fine

 

If not : i have no idea
