64-Bit Windows 7 Shows 2.75GB Usable Ram out of 4GB

[TerminatorXT]

I recently installed Windows 7 64-bit build 7600
and when I go into control panel, it shows that I have 4 GB installed
but 2.75 is usable....

does anyone have any answers

and yes its 64-bit for sure

 

[cjdutil]

does it show 4 gig in the bios?

does it show 4 gig in the bios?

yes it does
it showed 4GB with my old Vista 64bit also

Is 1.25 being set aside for onboard graphics, perhaps? Eventhough I have a separate video card on my Win7 setup, I still had to disable the onboard graphics sharing my RAM.

I have a dedicated video card
The GTX 295 1792MB GDDR3

weird. someone have an answer. im really curious.

any memory extension settings in bios? had similar issue with 6Gb being shown as 4Gb in bios and less in windows 64bit. PAE extension rings a bell.

 

[TerminatorXT]

nope, no changed memory extension in the bios

...when I go into control panel, it shows that I have 4 GB installed but 2.75 is usable....

What exactly is it that you're looking at in Control Panel that shows you this?

 

[TerminatorXT]

Control panel> System

So windows is using 1.25 Gb of memory.
And you have left 2.75 Gb.

I dont find that strange at all to be honest, I have 4Gb.
And 2.71 of free memory left after windows has loaded in.

Dont see the problem.

 

[TerminatorXT]

then why does it show 45% ram running nothing except for the sidebar???

 

[sminlal]

Control panel> System

OK, so this is where you're seeing it then, right?

And for "Installed memory (RAM)" it shows "4.0GB, 2.75GB usable by Windows"? Is that exactly what it says?

I've never seen that except under a 32-bit OS with more than 2GB of memory. Are you sure that it says "64-bit Operating System" beside "System type:" as shown in the picture above?

 

[TerminatorXT]

yes
100% sure its 64-bit Operating systtem

 

[sminlal]

Well I dunno then...

 

[TerminatorXT]

should a reinstall work

and if it does i''m probably not going to reinstall right now

 

[jla0]

Probably a brand name computer. They reserve system RAM because of the video card (textures).. you would probably have more available RAM if you removed it and used the on-board (if you have one). They do that for some reason.. with no way to turn it off in the BIOS (being a brand name if it is). Friend of mine had that with a Dell Dimension. He was pissed too. Calling Dell was worthless...

I build my computer from the ground up.....

I recently installed Windows 7 64-bit build 7600

Seeing as build 7100 is the latest officially released one, I'm wondering if you've downloaded a hacked 32-bit build. Maybe full of trojans too.

[TerminatorXT]

Wait I think I may have an idea

I know this is stupid and all but just hear me out

Every computer needs an antivirus, and I installed one
Norton v3

for those of you unfamiliar with Norton
its only for 32bit....

soo I'm guessing that.... Norton might be the cause???

 

[Andy2008]

Norton may be the cause of many ills, but I've never heard of it restricting RAM.

BTW, are there two Program Files directories, one of which is for x86 (or it might read 32bit - I can't get to my x64 Windows 7 ATM to confirm)? If not, then you have a 32-bit Windows 7.

Anyway, the only sure way to get rid of Norton is to re-install the OS. Even the removal tools for it still leave stubs of Symantec stuff lying around. Try something like AVG from free.avg.com instead.

My motherboard reserved some memory for PCI ports, or something like that. I had the same problem you're having, but I enabled an option in the bios to extend memory mapping beyond PCI. Hopefully you can do something like that to fix your problem.

 

[TerminatorXT]

Well I think we should just drop this

cause I'm not going to install Windows 7 until its released... so i'm not even going to use it

thanks for the input

yep. same here.
installed 4GB of RAM and W7 64bit also shows 2.75GB only.
my W7 Build 7100 RC is officially downloaded from MS website.
BIOS shows 4GB RAM installed.

use any 32bit programs we should know about?
