Ram Problem / 4gb Of Ram As 1.99gb Usable

Dec 13, 2009

Windows is only showing my 4gb of ram as 1.99gb usable. It used to be high although I cannot remember the value. I know that for sure because my ram score used to be 7. something and my hdd was lowest score of 5.9, now ram is the lowest with 5.5. Any ideas?

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.

RC 2.75 GB Ram Usable From 4 GB

May 13, 2009

Im running Windows 7 RC 32 bit on an HP Pavilion TX2510us Laptop With an AMD Turion x2 ultra 64. At first I had 3 GB of ram installed. A 1 Gig stick And a 2 Gig stick. The System Recognized all of it and used it. I then took the 1 GB out and replaced it with a 2 Gig stick, making a total of 4 GB max. Now when I go to the system properties, It says 4GB but only (2.75 GB Usable) Why is that?

Is it normaly supposed to use more then that? It had also crossed my mind that it might have something to do with my graphics card, (ATI Radeon HD 3200) because the index score on it has gone up. Not sure though. So I Figured I can try the 64 bit version. But can I run it, Givin the type of processor I have.

I know it says 64 on the sticker, but I have been told that just because it says that, it doesn't mean it is 64 bit capible. Im download the 64 bit version now, Hoping it installs.

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?

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.

6 Gigs Of Ram But Only 3.25 Usable

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

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.

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?

2.5 GB Usable Of 4 Total In Windows 7?

Oct 11, 2011

Under my Windows 7 performance information it is listed that I have 2.5 Gigs of usable RAM even though I have 4 installed. I think this is because I have 1.5 GB of graphics memory but I don't fully understand what that is. I also don't understand the difference between the listed "dedicated graphics memory(512MB)" and the "shared system memory" that I guess make up the 1.5 GB I'm "missing".I was thinking of installing a 64 bit version of my OS to take full advantage of my installed memory and I think my system is fully capable. I just need to have the right processor and enough memory to make it worth it correct? I assume my motherboard is capable if it is using a capable processor.

Trying To Make Laptop Usable

Jan 14, 2013

Wasn't sure if this should go here or in the security area. My company has given me a year-old Dell Latitude that they were going to throw out because it got a virus. However, the laptop has all of their network security stuff on it, so I can't even get past the CTRL + ALT + DELETE screen. I mean I can't get in and do anything on this computer. I know I have to buy a new hard drive and probably reinstall Windows 7, but how do I know that this will get rid of everything and give me a clean slate? I don't have accesss to the administrator password, either.

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.

6GB DDR3 Ram Installed BUT Only 2.75 USABLE

Dec 9, 2009

Okay so i have a Quad core x6850 Intel CPU, EVGA 280GTX GPU CARD.

Now i installed window 7 x86 bit version ULTIMATE. And i have 6GB DDR3 RAM INSTALLED INTO MY geforce Nforce 790i motherboard. Now the problem is that in Windows 7 it shows "Installed Memory: 6.00GB (2.75 GB Useable)". But in Bios it shows me that 6gigs in installed.

Now does that mean it is WIN 7 that is just reading my DDR3 RAM WRONG? But i am still getting the full performance for all of my 6GB DDR 3 RAM? Since my bios is reading all of the 6GB RAM?

Also i tried doing what other forums indiated i should be doing like type config and check mark or uncheck mark MAX MEMORY. Tried doing that, but noting happened.

Now the only thats left and i am having confusion with is, some people are saying i should Enable Memory remapping in bios? I have a nforce 790i motherboard, and i can't find that exactly in my bios mode. Is there any other way to fix this problem?

4gb RAM Installed, Showed 2gb Usable

May 9, 2009

I have 4gb RAM on the Dell XPS 1530 machine.

I installed Windows 7 64 bit from on two partitions.

The first one, a fresh install, Computer Properties shows 4gb RAM, the same value (4096) is also showed in Task Manager.

The second one, I upgraded from Vista 64 bit, it shows 4gb RAM (2usable), the same (2048) is showed in Task Manager.

I heard the story about Memory Remap, my mainboard didn't have it. However, the first case, it automatically recognize 4gb RAM, I guess Windows7 manages everything. Is there anyway I 'turn on' the rest 2gb in the second case?

Office 07 Usable Without License Key?

I just got a distressed Windows 7 unit that has Office 07 Home and Student installed on it. I'm trying to figure out exactly where I stand with MS on this. Everything functions perfectly, except every time an Office app is fired up it requests the license key. But the key is not necessary to run the program, and it will allow you to proceed without the key after a few nuisance screens.I would think that either the installation is valid or not. I don't have a key, so I'm stuck where it is for now, but I'd like to understand what's going on.

4gb Of RAM Installed, But Windows 7 Says 256 Usable

Jul 16, 2009

Earlier tonight I rebooted and noticed that it took an extremely long time to boot. Almost 10 minutes to get the desktop completely loaded. So I checked task manager > performance tab and it says I have only 256mb of RAM. So then I checked My Computer > Properties and noticed it said "Installed Memory (RAM): 4.00 GB (256 MB Usable)" I've had Windows 7 installed for a good 2 weeks now and never had a problem, until I rebooted tonight. I checked my BIOS and all my sticks show up. I DO NOT have a shared memory video card. Memory test checked out fine. I haven't installed any new hardware, nor touched the sticks at all. why Windows 7 started doing this?
