Not All Of Memory Is Usable

Aug 30, 2012

I have a computer that is running Windows 7 Ultimate 32-bit. It has 6 GB of RAM installed, but it says that 3.00 GB are usable. My understanding is that Ultimate 32 bit can handle 4 GB of RAM. What do I have setup in correctly?

Usable Memory

Oct 29, 2009

I know you've probably seen dozens of threads like this, but here's an interesting twist:

The laptop it's on (the Compaq Presario V2000) only has 512MB of RAM, and is showing only 383 available. Nothing near the level of the OS restrictions. (Besides, it's 64-bit.) I've already tried the solution here, but the "maximum memory" box was unchecked.

Any insight?

1GB Installed Memory, Only 1gb Usable

Nov 13, 2009

I have also checked the BIOS . but there is no place where i can dissble " Dram over 4Remapp" or something like that.

everything i can think of i have checked.

I know 32bit can't handle more than 2 or 3GB memory, but it can handle 2gb, that much i know.

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.

Memory Installed 4BG (usable 2.97GB)

Dec 16, 2009

I recently upgraded from Vista home premium 32 bit to Windows 7 Home premium 32 bit. My system now shows RAM 4GB installed (2.97GB usable) this never happened in my vista version.

I have searched numerous threads on this forum but and have found similar issues but none of the threads seem to have been resolved.

I am thinking to revert back to Vista if i cant make full use of my RAM.

Only 3072 MB Of Memory Usable On Windows 7 64 Bit

Dec 20, 2010

Today I noticed that my system is only using 3072mb of RAM, I have 4 GB in my system and they used to work pretty nice until now, before all 4 were usable, now Im missing 1. I thought this was because ram remap feature was diabled on the bios (BTW here's my board : Biostar G31 M7 TE). So I enabled it and rebooted my system. Turns out it's still the same... I tried also enabling the memory hole to 15-16 mb (the only setting appart from diables) same results. I think this is decreasing my PC's performance... edit: what seems to be doing this is the ''pci mmio allocation''

Windows 7 64bit - 6GB Memory But Only 4GB Usable

Mar 19, 2012

I have Win7 64bit with 6GB memory. The Windows System control panel agrees with that showing 6GB ram and nothing about a limitation. But today I was opening a lot of files and the program wouldn't let me open more files after Windows memory use reached 4GB. Task Manager showed 4GB used out of 6GB. I tried opening another file with a different program and my screen flickered and the program shut itself off, so it looks like the problem is with Windows and not the other programs. How do I get Windows to use all available memory not just 4GB out of 6GB?

4 GBs Of RAM Only 2.84 Usable?

Jan 22, 2011

For some odd reason, my new Windows 7 32 bit laptop is constantly using 40+ precent of it's installed RAM. I checked my computer's properties and found that Windows is only using 2.84 gigs of my computer's 4 gigs of ram. Is there any way I can force it to use 4 gigs? Or at least, force it to use more than my current amount? I have attached a screenshot of my computer's RAM specs.

Feb 8, 2013

I have an older desktop, Acer Aspire running Windows 7 Ultimate 32 bit, it had 4gb ram installed (I did know that only 3gb could be used)yesterday I took one of the ram sticks out ( had 4 x 1gb) and put in a different computer. Since then it has started crawling along, I have noticed that it says 3gb ram 1 gb usable. is this something that I need to go into the bios for? I ran the memory diagnostic tool this morning but did not get to see a report.

Only 2.9GB RAM Usable?

Mar 8, 2011

I have quite a new ASUS laptop, which came with 64bit windows 7 and I took off and installed my copy of Windows 7 32bit (I didn't see the point in having 64bit on a laptop).

When I first installed the OS and everything Windows said I had 3.25GB ram usable or something like that which is normal but for some reason I now only have 2.92 usable and I don't know why >.< (this may have happened when SP1 was installed)

The specs are:
Intel(R) Pentium(R) CPU P6100 @ 2.00GHz
4GB DDR3 Ram
Intel HD Graphics
Mobile Intel HM55 Express Chipset
320GB 5400RPM HDD

3.26 GB RAM Usable On 64 Bit

Dec 18, 2009

Okay, this is really weird. Previously, I had had a ordered a kit of 4GB ram with one defective stick. After installing Windows 7 Ultimate 64bit with the good stick, I RMA'd the kit back to newegg. The exchange arrived today, and after installing the new kit of ram, windows only recognizes 3.26GB of it! Under the system information panel, it says:

Installed memory (RAM): 4.00 GB (3.26 useable)

despite me having a 64 bit OS.

Whats up with this? I Memtested the ram and it shows up as only 3255 MB in there also.

Does anyone know why?

Windows 7 Not Using 4GB Of RAM - Only 1.76 Usable

Jul 31, 2012

I have 6144mb of ram on my Compaq Presario CQ62 402AU. So I have the 2GB Hp stick which came with the laptop (2GB DDR3 1066MHz) and I have a 4GB stick from G-Skill). So there should be 5.76GB usable, but I only have 1.74GB usable. This is what is it when I only had the 2GB. The Bios says there is 6144GB in there. Windows says there 6.0GB in there also.

So what I have tried:
- Running Mem Tests (HP one which came with my laptop and Memtestx86)
- Taking out the ram and putting them in there sorts again
- Taking out the ram, running a pencil eraser over the connecters and then putting them back in
- Doing testing so Only 1 is in and try that in both slots for both sticks of ram
- Swapping the ram positions
- Making sure that Max ram is not selected in Msconfig

So basic System info you may want to know (Most of my profile info is there of my computer) Windows 7 Home Premium 64-Bit SP1 Installed Memory (Ram) (This is from the basic system info page) 6.00GB (1.74GB Usable). The odd thing is that it worked fine for a while. Today I went to school with the 5.76GB and I come back home 8 hours later, the computer has only been on lock for this time and there is only 1.76GB usable.

3.25G Usable Out Of 4G RAM Windows 7 64-bit

May 21, 2011

i am running windows 7 Home premium 64-bit and recently upgraded my RAM from 3GB to 4GB. Windows 7 reports only 3.25 being usable. i have a dedicated video card an my onboard one is definitely disabled. my BIOS reports 4096MB RAM detected. max memory and CPU are unchecked in msconfig. from looking at the resource monitor i see that 770MB of RAM is labeled as hardware reserved memory.also i don't know if my BIOS supports a memory remap feature or not but even if it does its a locked HP BIOS so most setting are inaccessible.is there any way to get my full memory? or does anyone know why this is happening on a 64-bit os?

Dec 19, 2011

My motherboard is the ASUS Maximus III Formula, using Intel Core I5 760. And I recently did a dual boot on my system. One copy of Windows 7 Ultimate x64 on my original hard drive, and a Windows 7 Home premium x64 bit on another hard drive ( Hitachi ) and after a month or two, I had to format that ( Hitachi ) hard drive as I needed it for extra storage and now I'm getting only 2 Gb usable RAM but I installed 4Gb.

Oct 25, 2009

I updated my XP 32 OS to windows 7 64 bit professional. Everything works fine on this upgrade. BUT when i go >start>mycmputer>right click and select properties i see 6 gigs but only 3.25 GB usable. Any way i can use the rest of those gigs. When i bought windows 7 two days ago i bought 2 stick of ram with 2 gigs each stick. so i have (2) 1 gig stick and (2) 2 gig sticks.

Like i sed my PC (Alienware was built in Dic2005) originally was made with 32 OS xp if someone can guide me on how to get my info of my mother board I will be glad to follows those steps so i can post them here and hopefully gets some help. If not I just will return the extra gigs I bought.

PS- I reinstall windows 7 from scratched but with OS 32 bit and I could see the same 6 gigs but only 3.25 gigs usable.

4GB RAM Installed But Only 3.5GB Usable On PC

Aug 25, 2012

My PC says it has 4GB of RAM installed but only 3.5GB are usable, I have windows 7 home premium X64.

CPU: Athlon II x3 Unlocked to Phenom II X4 @3Ghz.
Motherboard: Asrock N68-VS3-UCC
RAM: 4GB DDR3 generic brand.
HDD: 1x 320GB SATA, 1x 250GB SATA and 1x 250GB IDE
GPU: XFX ONE 5400 series
PSUEM 500w PSU.

Windows recognized the full 4GB and the whole 4GB were usable but when I checked about 2 days ago it said that only 3.5GB were usable. I started to do a little research and I found out that my GPU might be using Hyper Memory so i tuned off my system, removed the GPU and when I went to see how much RAM was usable it said 4GB installed 3.25GB usable. So its not my GPU.
