Windows 10 6.6gb memory usable out of 16gb memory.

Q: Windows 10 6.6gb memory usable out of 16gb memory.

I've noticed my memory is sky rocketing up to the 90%s when gaming or idle. I checked my specs and have realized only 6.6gb is usable. I was wondering if anyone had a fix to this? Thanks.

Preferred Solution: Windows 10 6.6gb memory usable out of 16gb memory.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Windows 10 6.6gb memory usable out of 16gb memory.

Moire info needed.

Make/model of system board/computer.

What does your BIOS show? At first glance it appears you have shared memory, typically this is a laptop setup and if memory allocated to video less available to the system.

I recently did a new install of Windows 7 64 bit. I noticed windows showed 4Gb of ram (2.75Gb usable). I read tons of articles after googling this and tried several options to free up some more ram.

I have 2 options in bios to change memory remapping over 4GB. S/W and H/W.

When I enable S/W remapping, windows boots everything seems fine but I get a crackling sound from speakers. Bios shows 4Gb (3Gb usable). Windows shows 4Gb ram (3.0 available).

When I enable H/W remapping, windows BSOD during boot, but bios shows 4Gb ram and all 4 Gb available.

So, does anyone have any suggestions as to how to eliminate the BSOD after enabling H/W memory remapping? Try installing Windows 7 again? I read some people saying bump up the voltage on ram perhaps? I've never done any overclocking, but would try if someone thinks it may help.

I've tried several different setting. Any help would be greatly appreciated.

A:4Gb memory (2.75 Gb usable) memory remapping in bios causes BSOD

This sounds almost like a bios memory compatibility issue to me.
Have you tried checking the ram in both modes using memtest?
RAM - Test with Memtest86+
Since the memory is obviously the center of this I think it bares testing.
Keep in mind you'll need several passes each way with memtest to get any kind of accurate result and will take some time

Inspiron 14z n411z (Laptop): Authoritative confirmation of memory upgrade to 16 GB, 16GB, 16gb

There are various claims that 14z/n411z can be upgraded to 16GB (unofficial or therotical based on CPU-i5 being Sandy bridge)

Here are the main issues on this subject that has left many customers scramble for answers and find themselves confused:
* It is the interest of customers that Dell come out with an official statement "confirming" or "denying" if this is possible
* Yes, at the time of sale Dell stated that max permitted was 8GB. But now therotically (Sandy Bridge CPU can support 16Gb) and based on other users experiments it seems possible, but no concrete/firm proof available.
* If it is possible, Dell can always state that it will not support 16GB, though it (Dell) has tested it as possible in their labs.
* In the absence of a confirmation from Dell, most memory vendors are not selling memory 16 GB upgarde for Inspiron using their "configurators".
* There is another confusing twist to this problem, created by the fact there is another Dell XPS model facing same problem. But they newer CPU, for which most vendors are selling the memory upgrade on their configurators.
* For Dell, most users are now "past their Warranty" period. There is no liability in answering this question. In the LARGER interest of customers Dell should clear this doubt.

10-31-2015 @ 4.25pm On the A740, I figured out that it will allow 16GB laptop RAM stick in its single memory slot. However, I did find out that a 16GB single-slot laptop memory stick will work on the A740and will get you to 16GB memory on only one memory slot (which the A740 has). The A730 was easier because it has two memory stick slots (so you could do 2 * 8gb = 16GB),but A740 only has one memory slot.  Therefore, you can not go with two of the cheaper 8gbmemory, because you have to spend more on the 16GB single-stick laptop.  So, hopethis helps other people.

i have a new HP Z400 workstation. it has a new install of windows 7 enterprise 64bit with all updates. the pc came with 6gb of ram installed. i purchased 6gb of kingston memory that was specifically listed for this workstation. the ram is installed as 6 x 2gb modules. slot 1 factory module slot 2 kingston module slot 3 factory module slot 4 kingston module slot 5 factory module slot 6 kingston module. when this pc just had the factory modules it shows 6 gb installed 5.83 usable. it now shows 12gb installed with only 3.23 usable. what is causing the decrease in usable memory as well as what is causing the usable memory to be a fraction of the installed memory?

A:adding memory results in less usable memory

First reseat the ram sticks.
I would change locations of the sticks too
If still have the problem, take Ram Test
Download memtest86 and test RAM
Run for 6 passes/

It could also be mix and match a no, no.

Just as the topic looks, that's what I'm having an issue about right now. Now, lets begin by laying some different things out on the line. 1) I used search, 2) I used Google, 3) I even tested this on different machines (will explain below), and 4) I put this in the right forum... I hope..

Ok, I work in an office and I got an agent to come to me to help them install Java. Knowing he ran Windows 7 - Home Premium, I checked the System menu for what version OS he was running. I noticed 64bit, but couldn't help to notice that he had 3GB installed (2.75 being used)... Right away this through up a red flag because I thought that Home Premium 64bit was able to fully use every bit of installed memory up to 16GB. Acer is the manufacturer of the laptop, so I don't know if they might have something messed up in the BIOS or if it is simply because he got it about a week after Windows 7 was released.

The reason that I am fearing this is because I have a custom built desktop that is currently running 4GB (3.25 usable) of the Windows 7 RC Ultimate 32bit, so I know that I'm only going to get about that much out of my RAM. However; because it is soon time to reformat, I have a Windows 7 Home Premium 64bit CD + Key waiting to be used, and another 4GB of memory to be installed. I don't want to have an issue when reinstalling that I'm going to be missing any bit of RAM being used either just because I'm using Home Premium or any other reason.

A:Installed Memory (Usable Memory)

Hello Joshgt2, and welcome to the forums

Theoretically 64bit can address 128GB of RAm , although Motherboards typically do not support such amounts yet.

Certain chipsets (Such as AMD) using built in graphics, will use a certain amount of RAM dedicated to graphics only.
(naturally it pulls this dedicated graphics memory from you installed RAM)

So if it is set dedicate say, 512Mb in the bios, and you have 4GB of RAM installed...

In Windows you would see something like 4Gb installed (3.5 useable)

By the same token, if you have 8GB installed, it would show 8GB installed (7.5 useable)

If you install a actual graphics card, and disable the onboard, you will gain full use of your RAM again, As a graphics card has its very own memory onboard.

hope this answers your question

I have an hp G62 notebook running windows 7 with 3 gb of installed memory. However, of the 3 gb I only have 1.74 gb usable. The rest is hardware reserved. I understand that the gpu will share some of my memory, but this seems like a little much, especially considering that my computer is consuming about 50% memory while nothing is loaded.

I did a little test and I switched out my memory (I have a 2 gb stick and a 1 gb stick.) I put the 2 gb stick that was in the first memory slot and put it in the second. I then put the 1 gb stick that was in the second slot and put it in the first. When I did this, my available memory went from 1.74 gb to 763 mb. Is something wrong with my memory slot? I seriously considered this for a while, but if something was wrong with my memory slot, wouldn't my system not recognize the full 3gb?

Any help would be appreciated.


A:Windows 7 64-bit 3gb memory only 1.74gb usable

No, but there may be an issue with the memory chip. Remove all but one stick of RAM. Download the ISO image for Memtest in my signature. Burn the image to CD using IMGBurn or to USB Flash Drive with Rufus both in my signature, boot off of the media and run the tests for at least 7 passes each on each stick of RAM separately. If you get any errors (Red in the bottom panel) then that stick is bad and needs to be replaced.

I was having a debate about this issue and my friend suggested the problem could be that the heatsink is on too tight. I told him "That's ridiculous!" He pointed me to this site where it is listed as a possible solution to this problem. (see point 8 Asus X58 + 6/12GB memory overclocking - detecting less memory than installed - i4memory.com - different look at memory)

I've never heard of this and can't find reference to it anywhere else.

So my question is: Do you think this is a valid fix? Have you seen this fix the problem?

To be clear, the problem I mean is that in System Properties Windows reports, for example, 4GB RAM installed (3GB usable) in a 64bit OS.

A:Windows reporting less memory usable

To be clear, the problem I mean is that in System Properties Windows reports, for example, 4GB RAM installed (3GBusable)

Maybe its a 32-bit system

the heatsink is on too tight.

Heatsinks have nothing to do with RAM but some points in this list are true

Hi guys, I have only recently come across an issue where my computer has been running low on memory, when I open up task manager it shows up with only 3GB of RAM available, I have 8GB of 2400mhz RAM installed and this issue has only just come up.

I'm worried this may have had something to do with some supposed 'fixes' I had to do for BF4, but this issue didn't show up straight after and I am not entirely sure of the steps I went through, thought I'd add that in there just in case.

My specs:

GPU: R9 290x msi
Mobo: A88x msi-g45 gaming motherboard
CPU: A10 7850k black edition
RAM: 8GB of Corsair Vengeance 2400mhz
OS: Windows 7 64 bit

If there's any more information required please let me know and I'll post it, this issue is driving me nuts, can't even have the most basics of programs running without having to close them due to low memory!

Thanks in advance.

A:Windows 7 64bit: 8GB Ram only 3GB usable? LOW MEMORY ISSUE!

Hello naBs.

Can you go to msconfig > Boot tab > Advanced Options and ensure "Maximum memory" is not checked. If it was checked, uncheck it and reboot.

Also, check your BIOS and enable "Memory Remap" assuming your BIOS supports/has this option.

Remove one stick of ram, ensuring that one stick is still in and in position 1 (usually they are labeled) and reboot. If this works, try the second stick of ram. If your PC doesn't boot with one or the other, you probably have 1 bad stick of ram or a bad ram slot.

Try these tasks and report back

I have two sticks of 4gb PNY RAM (8gb total) installed in an Asrock A75M motherboard, which supports 16GB of RAM. I've already flashed my BIOS, thinking that may be it, but it didn't work.

Windows 7 as well as my BIOS show that 8GB of RAM is installed, but only 3.73 is usable. I have an onboard video card, so 256MB is dedicated to that, which makes sense, but why isn't the other 4GB showing up?

I am looking to purchase a Dell XPS 8920 to replace a aging Dell XPS. The only options that they offer are 8GB and 16GB of base memory. The XPS 8920 indicates that it is has a maximum memory capability of 64GB with a 16GB memory module in each of the four slots.
Does Dell provide a single 16GB memory module or 2 - 8GB memory module when 16GB is selected?

A:XPS 8920 16GB Memory Configuration

I have a Dell XPS 8910 with 16GB of memory and it came as a single 16GB memory module, so it runs in single channel mode. If you research single channel vs dual channel there is not much performance difference unless you are doing serious simulation/parametric analysis. On the plus side, if you plan to increase memory to 64GB for example you will not be wasting two 8GB memory modules.

Hi there! Searching for a little while now I am wondering why the memory upgrade of my recently acquired notebook does not work as I hoped for. Then stumbled upon this forum so hopefully here somebody is willing and able to clarify the mystery... I did buy the notebook knowing (especially the graphics part of) the processor would greatly benefit from dual-channel memory so I was happy to notice I had two DDR3L-1600 8GB Samsung ones available. Installing was a piece of cake (of course) and the BIOS shows (correctly) two banks (bank 0 and bank 2) filled with 8GB each. So far so good. But then.. starting Linux I had the option of running a memory check: Memtest86+ 5.01 Then things got weird:- At the bottom of the screen Memory SPD information shows two times 8192 MB DDR3-1600 memory installed- Top left of the screen shows: Memory 7114M (???)- Middle of screen shows RAM 474 MHz (DDR3-948) (???) And within Linux I am told I do have about 6.7 GB of RAM installed. I am sure you can imagine I am puzzled and wondering if anyone has similar experiences or, even better, knows a solution.. as far as I can tell the memory should be compatible and I do not intend to buy other memory unless I am sure this would solve the issue. Thanks for reading!

Hi all,I'm considering buying an X240, mostly because of the screen resolution.The X240 downside is the limitation to one memory stick, thus, 8GB.

I currently run Windows 7 Home Premium 64-bit, so that shouldn't be the problem.
I have come so far that i can say the problem that i see is that the 8 or so remaining GB is reserved for hardware. How do i "Unlock" this memory?

I have a problem which many of the people have but I want to find a better and quick answer to my exact problem.
First of all, the problem is this
I have a Custom-built Desktop PC with the following specs.
Intel Dual Core Processor @ 2.00Ghz
RAM 4.00 GB (3.00 GB usable)
Graphic card: Nvidea Geforce 9400 GT.

So, the problem is as you can see, I have recently installed 4 GB Ram in my computer, When  I open my BIOS it detects both the RAM sticks-i.e- 2GB, 2GB each (they are a model of HP) (the RAMs are DDR2). But when I start my windows 7 and open the system
properties, it says that only 3.00 GB is usable. And the problem for this is certainly not a bad RAM because 3 GBis usable so 1 GB of the supposedly bad RAM stick is usable.
However, I found the problem when I open my "Resource Monitor", where in the memory tab it says that 1096 MB is "Hardware Reserved". This is too much as many other computers have only 2 mb or near to it "Hardware Reserved". I really
need to solve it. Here are some points.

-Actually my mother board manual says that only 2 GB is supported but I heard that that limit isn't necessary to follow, and 3 GB is usable so it is already exceeding the limit.
-I have windows 7 32-bit, which has a limit of 4GB and since I am not exceeding that , then that should not be the problem.

The usable memory is (2 GB only) less than the installed 4GB memory on Windows 7, windows 8 and Windows 10 (Checked in all windows).Windows report that there is only 1.99 GB of usable system memory on a computer that has 4 GB of memory installed (System Properties).How can i use 4GB memory properly?Note: 1) Sometimes My laptop restarts with showing blue screens.2) and i was noticed that all same models laptops (HP) have the same problem(all same catagory laptops)3) PAE patch was solved the problem (temporary) in windows 8!!4) I have no permanent solution (in windows 10) about this problem.

I have 4 gigs 2x2 on windows 7 x86

it shows 4 GB (3.25 GB usable)

I have gone through msconfig and made sure the maximum memory was unchecked, and I've also tried setting a max memory amount, but it wont give me that last 750mb. Also my video card has 512mb of ram itself so it shouldn't be stealing 750mb from my system memory should it?

A:usable memory problem

I see you have 32-bit (x86) Windows 7. 32-bit Windows cannot use a full 4GB of RAM. A lot of people report only having 3GB usable, so you are actually getting a little more than many. The only way to be able to use the full 4GB is to use 64-bit (x64) Windows, but if RAM is your only concern, you won't see much difference.

Hi ;I have an asus laptop and I clean installed windows 8 pro x64...in pc info it says 4.00 gig memory(3.79 usable)...that it wasn't like this before on my last windows 7 sp1 x64...what should I do now?...
PS: in my bios there is no option named memory remapping or etc.

A:3.79 gig usable from 4 gig installed memory!

Are you on 32bit or 64bit?

32bit is limited on the amount of ram it can use.
Also you loose some ram to system bios and graphics cards mapped to memory.

See here for details (applies to all windows after & including vista)

I used to have Vista (32-bit) on the machine, 4 GB RAM installed on the motherboard. Vista was able to allocate around 3.00 GB for itself, with a videocard that had 256 megs of RAM on it.

As my old video card busted, I changed it into Club3D's Geforce GTS 250 with 1 GB of memory, and naturally didn't take a look how much Vista had "available memory" after that. Got the Windows 7 update on Vista, and now I'm seeing in the system :

Memory : 4,00 GB (2,00 GB usable)

I took a look at Task Manager, and it also shows 2048 MB as available memory. Looking at the videocard's specs, I can see that it has 1024 MB of dedicated video memory, and shared system memory 767 MB.

Knowing that the maximum memory 32-bit Win is able to map is 4 GB, still the math doesn't seem to work for me. 2 GB for OS + 1 GB for the video adapter makes a total of 3 GB. If the shared memory isn't in the 2 GB Windows 7 shows as available, then we'd have 2 GB + 1 GB + 0,7 GB = 3,7 GB which starts to sound more reasonable.

For fact, I know that I have memory re-mapping on in BIOS, and BIOS check says 4096 MB of memory installed. The motherboard in question is ASUS P5B. Should I somehow be able to get Windows to use 3 GB of the 4 GBs installed, or is the latter math part right, and the system is already using all that it can?


A:Maximum usable memory for 32-bit Win 7

No you won't be able to use more than 3.0-3.25GB of RAM in Windows7 x32 depending on your MB

Use X64 instead

Hi there,
I just bought a new 4.gb corsair DDR 3 memory card for my pc recently, and after installing it, it comes up saying it has 6gb of memory installed (2gb usable).
That is from the system tool in control panel.

Of course task manager confirms in the performance tab, that there is only 2gb available still.

I have double checked the motherboard specs for compatibility, and it has the DDR 3 cards on the support list, so I don't get why it's coming up as unusable...

The board is gigabyte gap55ud3
Running windows 7 ultimate 64-bit
I7 core Intel

What can I do to get this memory card working?
Could the board maybe only have a couple of slots that work in the frequency range of my card? (1333mhz)
OK, so after a bit of trouble shooting, I noticed a couple of things:
Firstly, the first memory slot (first on the left) on my motherboard is dead (due to the shop mounting my motherboard incorrectly, and shorting it out), so I had the 2gb card in the second slot, and had the 4gb card installed on the 3rd slot.
I took out the 2gb card, and replaced it with the new 4gb card, and it runs fine.

However, this still doesn't answer for the fact that it picks up the memory as unusable, if I install the card on the 3rd slot.
Could my guess earlier have been correct?
Could it be that only 2 of the slots are compatible with the higher frequency cards (1333), and the other slots only work with lower frequency cards?

A:6gb memory installed, but only 2gb usable???

Check the motherboard User Manual. When mixing and matching memory cards, there are sometimes specific slots for them to be installed into. And sometimes you cannot mix different sized cards. Again, it should all be covered in the User Manual.

In any case, installation wouldn't appear to be an issue. As you have already noted several times, the motherboard and OS are recognizing 6GB. Which would lead me to believe it's an OS related issue.

When I check System Properties, it says Installed memory (RAM): 4GB (2.75GB usable). When I check Task Manager, it also shows me 2814MB Total physical memory. I am using Windows 7 RTM x86. How can I get all of my installed RAM working? I googled a bit, found out something about memory remaping option in BIOS, but I have no such option in the BIOS. I am using a Acer Aspire 5737Z laptop with a Geforce 9400m graphics card. Please, any help would be much appreciated.

A:Installed/usable RAM memory?

Hi starterz and welcome to Se7en Forums

That looks about right. On 32-bit systems, the total amount of memory that can be addressed is 4GB. Within that address range, there are also the system I/O devices and other hardware. These in effect take up some of the available memory space, so the amount of physical memory available to your system actually reduces by that amount. Depending on your system's hardware and configuration, this can be anything ranging from 256MB to 1GB (typically 768MB). However, that can vary. In addition, on a laptop the GPU is allocated a portion of your RAM for its own use.

This is from my system. What does yours show for the Graphics section?

Hi there,

I have just added 4Gb Crucial memory (2x2Gb) to my existing 2Gb RAM (2 x 1Gb) for 6 Gb total. The system info shows 6Gb but only 4.94Gb usable.

Any suggestions as to the difference and how I might get more usable memory?

n.b. When only 2 Gb was installed it all appeared usable.

(I have looked and Max Memory is unchecked in msconfig)

A:Memory upgrade not all usable

I know that crucial tells you what you should use, but the first rule is dont mix and match, nothing but trouble
Second take a memory test to see if its the slots or the sticks or neither

To the future posters, lets not get into the mix and match thing. If thats not the problem, here fine, lets just find out what is the problem.

Sorry my bad English.

A:Installed Memory 6GB but 2GB usable.

The memory limit on 32bit operating systems is 4gb, so you would ov been better off with just another 2gb dim. Try removing the 2gb dim and boot with only the 4gb

VGA Memory heatsinks, re-usable?


I'm helping someone transfer their VGA Zalman fan on a dead video card to a new one, but are the Heatsinks re-usable? Especially since the thermal tape probably wouldn't stick anymore if removable at all.

Or should this person just throw in cash for new ones?

when i start my computer. it show 1024mb ram . that counts that up. but in everything else it shows 2GB bit 1 usable.
and it says that 1024mb is hardware reserved, ( maybe it is that ? how do i change that ?
I have run a test. nothing wrong with either of the memory sticks
I also have seperat graphic card with 512BM Ram on

can someone help me , please.

Thank you
