64-bit Win 7 Ram Compatibility - 2gb Only 1.87 Gb Usable


I'm now using windows 7 32-bit, but my programs require an upgrade to windows 64-bit version. I have used windows 7 upgrade advisor to check if my computer can install a 64-bit version. Then i received a report that said my ram is not compatible. I install 2gb of ram but only 1. 87 gb are usable, so the report said i wouldn't be able to install a 64-bit version of windows. It require a whole 2gb of ram. I now wonder to know that can i install that 64-bit version?

Dell Netbook - Installed Memory 2gb (1gb Usable)

Windows 7 on dell netbook - installed memory 2gb (1gb usable) - why can i only use 1gb of ram? How can i make all 2gb usable? I have a dell inspiron mini 10v netbook. It came with 1gb ram and windows 7 starter. I upgraded to windows 7 ultimate and like it much better. Since memory was only 1gb i installed a 2gb chip instead. The computer/bios is happy with it but windows 7 will only use 1gb of it.

Bsod When More Than 2gb Of Ram Installed

Customer brought in a toshiba portege m800 laptop. Problem it is having is that on a clean install of windows 7 pro 64bit, it will bsod with 0x7e, 0x0a, or 0x1e when there is more than 2gb of memory installed. It boots perfectly fine with 2gb or less.

Motherboard, processor, hard drive, and memory have been replaced. I've tried using different brands of memory, different speeds all with the same problem. All memory that has been used has passed every test thrown at it. The bios reports the correct amount of memory installed no matter how much is installed. The computer can handle up to 8gb of memory.

I know vista had a similar problem, but i was not able to find a hotfix for windows 7 and of course the vista hotfix will not install on 7. Any ideas on solving this problem?

2.7 Out Of 3.00 Installed Ram Usable

I'm running windows 7 ultimate 32-bit and have 3 gb of ram installed in my computer. 32-bit editions of windows are supposed to be able to use up to 3. 2 gb of ram or something like that. However, when i look at a detailed performance report, it says that only 2. 70 gb of my 3. 00 gb installed ram is usable. Why is this?

4gb Ram But Only 3.3 Gb Is Usable

Im using windows 7 enterprise 64 bits on my hp nw8440(chipset 7600) laptop and have updated the system by connecting to microsoft and it is a genuine copy too. I had earlier one stick 2gb memory and recently inserted another 2gb stick on my second slot. It is working fine on microsoft vista and shows that my entire 4gb is utilized by the system.

But after i upgraded my system to windows 7, it shows that my system has 4gb ram but only 3. 37gb is usable and the rest 641mb is reserved by some hardware. I checked my graphics too and it has its own memory so in no ways it is using the system memory. May i please know the work around for this problem.

Installed Vs Usable Ram

I had a quick look at some other threads which talks about usable ram being shown less than installed ram. Mine is also same case. In my case, my windows 7 x64 ultimate box shows: installed memory (ram): 4. 00 gb (3. 75 gb usable). I understand that . 25 is gone, due to other devices/motherboard etc. Now my question to experts: considering that there are no hardware changes and if i add 4gb more ram (making total 8gb of physical ram), then what will be the value of my usable ram?

Ram Upgrade Problem From 512x4 (2gb) To 2x2 (4gb)

Ram. I upgraded from 512mbx4 (2gb) to 2gbx2 (4gb) when i run the 4gb by it self it boots up fine but i went to add back in 2 of the 512mb chips it will not boot up to windows. The computer sees the ram fine but windows come up with widows damaged repair files or boot up normally when i say normal it reboots and comes up to the same window.

When i remove the two 512mb chips it boots up fine again. Is windows 7 compatible with 5gb ram? Why do i get an error from windows and not my bios? They are all ddr2 chips but  the 2 512 are at 533mhz and the 2gb chips are at 1066mhz. Can i buy 4 more giabytes of the 2gig chips for a total of 8gb and it will work?

Update i bought 4 gig more of the same ram still wouldn't work must be time for a new motherboard! Dell support now sucks won't tell me how much ram my computer will take and if you want to call and ask it's like $50. 00.

Win 7 64-bit Ram Is Gone

Upgraded from windows vista 32 bit version to windows 7 64 bit version, hoping for the improved performance by being able to use all my ram in the 64 bit version, my 4 gigs of ram previously being limited to 3. 3 due to the inherent nature of 32 bit os's. I formatted the system drive as directed so i could put in a fresh 64 bit install on the system. After all was up and set, i hit the desktop and checked my ram, it was reading 2 gigs.

Upon further investigation it is now showing 2 gigs of ram in bios as well, but here's the sticker. It's detecting both dimm 2 gig sticks, just only half of each stick! Did windows 7 quietly flash my bios? I can't fix this issue no matter what settings i try, and post is quite insistent i only have 2 gigs now. I tried changing each stick individually and with each one only in the system, both each read 1 gig alone, they were 2 gig sticks before windows 7!

Motherboard: evga nforce 780 sli
Ram: 2 gig  patriot dimm 800hrz ramx2

Not Showing All Ram In Win 7 32-bit

I have just built from the ground up a new system with 4 gb ram. I have installed win 7 32 bit. The bios shows 4g, but windows only recognizes 2. 4 gb. I have verified the following (stolen from other forums): bios. You can check with your bios manufacturer, about how to enable the maximum memory.

Check the advanced boot options.
1. Go to start, in the search bar type msconfig and press enter.
2.system configuration window will open on the screen.
3. Click on tab named "boot".
4. Click on "advanced options" and uncheck the box for "maximum memory".

I have verified the max memory is unchecked, and found it unchecked.

For the record, i have the following hardware:
Msi nf980-g65 mobo
4gb ocz ddr3 pc1600 (2x2g)
2 nvidia 7800 gt (256 mb) in sli

Win 7 X86 32-bit Only Recognises 3 Of 4 Gb Ram

Windows 7 x86 (32-bit) only recognizes 3 of my 4 gb ram. Should i upgrade to windows 7 x64 (64-bit)? I just upgraded to win 7 from vista (both x86) on my sony vaio vgn-280e which was shipped with vista home prem x86 and sony state that it is capable of 4gb ram. I have just upgraded from 3gb to the full 4. And of course only 3 usable according to system properties.

You all say that it's cos x86 oss aren't capable of 4gb ram but that's just not the case with everyone, i've read other forums where people have. And also where x64 users can't access all their 4gb, only 3 or 3. Xgb. I have run linux x86 on here, which uses the full 4, and have an os x leopard install which also detects and uses all 4gb. My bios detects all 4 too. Is there absolutely no way that i can get win 7 to use the full 4gb ddr2 (pc-2 5300 667) ram i have installed?

Further system spec:
Mobile intel 965 express chipset family
Core 2 duo 667mhz t5450 cpus
Intel gma x3100 video (total available graphics memory: 358mb - 64 system, 294 shared)

Also: if i upgrade to win 7 x64, and the full 4gb ram is utilized by the system, isn't the trade-off that an x64 os is more demanding on system resources including ram? Ie. Probably performance-wise i'm not any better off?

Extra question to you: how do i update bios? My bios is showing the full 4 actually, so is my os x install (and using it too). But win 7 x86 says 4 installed, using 3. How can i tell if that extra 1 is or isn't "wasted", ie is it going to graphics (c. 300mb in my case) etc?

Win 7 64-bit Crash - Ram Issues

I recently picked up a copy of windows 7 and thought i'd do a few hardware upgrades at the same time, notably picking up an extra 2x2gb of ram.

The (clean) windows installation continually crashed after the "completing installation" restart, so long as these new ram chips were in the machine; when they were removed, the install went flawlessly. Subsequently, when i put them back in after the install, the computer began to crash just after clearing the windows load screen (the same location as during the install).

I have since tested both these two ram chips and some extra 1gbs that i had laying around in various configurations and amounts to the point where i think i can say that all the ram sticks work fine, as do the slots on the motherboard. I even flashed the motherboard bios hoping that would solve my troubles, but no luck. The bios recognizes all installed ram, and only crashed *after* windows began to load. As near as i can tell, using completely different ram sticks than my new shineys, windows crashes only if my system exceeds 3gbs of ram. Under or at 3gb is fine, in any ram slot configuration, but as soon as i throw the extra gig in it starts to crash.

I've seen other cases on the 'net of similar ram issues caused by the motherboard, but microsoft's compatibility center seems to indicate i should be alright.

Any ideas?

System specs
Asus m2a-mvp mobo
Amd athlon 64 x2-6000+ cpu
Radeon x1950 pro video
Wd 1tb sata hd 7200rpm w/t 32mb cache

Win 7 Home 64-bit Ram Issues

Firstly, pc spec etcmobo = gigabyte ga-n650sli-ds4 http://www.Gigabyte.com/products/product-page.aspx?Pid=2514#ovram = corsair xms2 6400c5c 1. 8v ver 5. 1 (currently at 2*2gb sticks)graphics card = nvidia geforce 260 gtx "approx" total memory 2671 mb (as read from dxdiag)cpu = intel core 2 quad @ 2. 40hz(4 cpus)

The issue im having is im trying to upgrade to 8gb or ram on the above mentioned ram sticks but when ever i go above 2 sticks and enter the realms of >4gb ram windows gets as far as the "starting windows" screen and thats it, it wont even play the little animation. The usual hold-down-power for 4 secs to get a power down goes to a single push at this point (unsure if thats relevant).

I have 4 slots and i have tried all the sticks in all the slots (its been a long night). This is all on the back of a new install after something went horribly wrong in the msconfig interface and my machine was stuck in a loop asking if i wanted to repair windows or start normally both would just reboot the machine back to those options.

In the msconfig interface i have unticked the maxi mum memory (an it support told me to tick it and set it to 0 which is how i got the above issue)regarding bios. My bios can see i have 6gb running when i have the 3 sticks in, not even got to 4 sticks yet. But it just seems windows doesn't wanna play ball. Iv never ungraded my bios before as all the warnings signs tell me not to unless its really really needed. I really hope someone can help with this as iv ran out of things to try.

Dell Xps 710 - 8gb Ram With Win 7 64-bit

Unable to get to 8gb ram on x64 dell xps 710 windows 7. Less than 6 works fine. Notice asymmetric vs interleaved and sdram speed listings change. Dell xps710 did clean install of windows 7 x64 from xp. All went well and things worked fine for a while. Decided i wanted to get more out of my x64 machine so decided to upgrade the ram from 4x1gb to the system max 4x2gb. I originally ordered the wrong ram (pc2-6400 800mhz) and when i installed them the system wouldn't even turn on.

Picked up the correct pc2-5300 667mhz 4x2gb units and after a clean install i put 2x2gb sdrams in with 2x1gb original sdrams. Machine shows 6. 0 gb installed and lists them as 667mhz and dual asymmetric. Everything works fine.

If i installed 4x2gb sdrams, the system says 8gb installed but lists them as 800mhz and dual interleaved? Won't make it through startup. Will try to do a repair but nothing works. Go back to 6 or 4 gb and things are fine? Any ideas?

Win 7 64-bit Bsod When Playing Wow Game - Ram Issue

I've been getting windows blue screen of death for some time. I thought it was one of my ram because after swapping them in and out of every slot and even one at a time. One of them was the one that was causing the bsod while the other one was stable. So i replaced both with 4 new sticks and now i'm getting bsod even more often. Like every 30 mins. Before i used to only get it when i was playing a game like wow when i had 2 sticks of ram in and i could go days without crashing. With 1 stick it was constantly stable. Here's are my 2 most recent errors:

Problem event name: bluescreen

Home 64-bit Compatibility Issues

I have a hp dv6-1355dx and i have been having issues running programs on windows 7 home 64-bit and don't like it. First of all i have a windows 95/98/xp/vista games called "star trek armada", "star trek armada ii demo", "star wars galactic battle grounds - saga edition", and i also have a game production programe called 'game maker 7". With the star trek games they install ok but when i try to play them they say i don't have enough virtual memory, they both need a minimum of 256mb and a recommended amount of 1gb, and according to my computer i have 8gb virtual memory.

With the star wars game the graphics are messed up but the computers graphics card is more then enough to support it because my computer call support 1080p 3d graphics and the game is not hd or 3d. The "game maker 7" program keeps on reverting to the free lite version from the paid for pro version, but it does not do this on my windows 7 home 32-bit htpc i also have it on, and it also is not showing some of the programs tap tiles, but they are shown on the htpc, so would you know what could be the problem, i know it it something to do with the 64-bit part of the os, but i don't know if it is just that or not. I have also contacted hp and yoyo games (game maker 7), and am waiting to here from them. I would appreciate it if you could at least help me trouble shoot the problem.

Xp Mode Not Usable

I want to load and run old software which will run on my xp machine. I loaded w7-pro, then xp mode, and then w-virtual pc. Then i was informed via warning box that i needed, and don't have, a hardware visualization function on my cpu. No, not just bios, the hardware!  I just bought my computer saturday, a new asuz laptop with w7 installed right on it. Why do i now need to have hardware on my brand new computer, which i didn't know about before, just to run xp mode?  Is ms working on a solution that doesn't require additional hardware?

Upgrading Ram - Which Type Of Ram I Would Need?

Currently i have a windows vista 32 bit, and am going to go to windows 7 64 bit. I only have 2 gigs of ram right now but i want to upgrade to 4 gigs.

Current specs:
Intel core2 duo t9300 2. 5ghz
2. 00gb ram
Windows vista 32 bit

1- i was wondering how to find out which type of ram i would need. (Btw, this is a laptop)

2- is there anywhere that can give instructions for self installation (i heard it was easy to do myself), or if its even wise to do it myself.

3- would it would benefit me to install the ram before or after i did a clean install for windows 7

Ps- any reliable companies that you would suggest that make ram.

Removable Drive Not Usable In Win7

I'm glad to see that in less than 24 hours you directly contributed to the loss and destruction of 2 removable hard drives i own. Not only did they both work in other machines powered by xp but the data on them was crucial. I did my share of research and found that the only solution anyone representing microsoft provided for the issue of removable drives not usable in windows 7 was directly related to a chipset or hardware issue (of course).

Unfortunately, on the initial install of windows 7 rc and windows 7 ultimate 64-bit the drives were usable and able to be read. But now, i have over $150 in hardware that is completely useless because of yet another untested patch or os related change. Not only did my drives not show up via plug and pray, they did not even post to the system. But luckily the sata drives received power from the motherboard and started spinning as they should.

Unfortunately, given that i could not "safely" stop the hardware before disconnecting, i was forced to either reboot or disconnect the devices. But, as we all know, when you hard stop a disc spinning at 5400 - 7200 rpm there is a strong possibility that there will be negative results to follow the action.

In the end, i am positive that the largest software company in the world will be quick to note that this is a hardware issue. Even if the devices previously worked on the system. There will be no compensation. No fix. And there is a very good possibility that there will not be any response to this posting. If anyone representing microsoft is willing to help, i can be contacted at email removed for privacy.

Visual Studio 2005 Pro Compatibility With Win 7 Pro 64-bit

Can i use visual studio 2005 pro on windows 7 pro 64 bit? I use visual studio 2005 pro on xp pro 32 bit. Can i use it on windows 7 pro 64 bit?I have looked on the vs site and could not find a definitive answer to using this version on my new os. I know, they're putting visual studio 2010 et al. I do not have the kind of cash they're trying to get from me. T least, if i can use it, i can do some self made/self-used projects. I will download the free development systems. But, they run out after 60-90 days. I still need to get ms office standard 2007/10.
