I bought this system in Febuary of this year it came with dual 1G ram.
When I first got the system I was checking it out and in the control panel on the systems page it said I had 1024MB of ram.
So About a month or more ago I started Having Problems. I first posted in High Jack This Forum for help with posible viruses or spy ware.
Along the way of getting help with those problems I noticed that I now only have 766Mb of ram. I was told this must be a hardware problem cause there is no known software or virus that can steal ram like that. I opened the case on this laptop and seen that there are two(2) memory (ram) sticks of 512k each.
What I don't understand is, If this was a hardware issue Wouldn't I have lost 512k of ram not just 258k? I could see losing 258k if the system had 4 sticks of 258k each, I would just know that one of the sticks was bad but how can just half a stick be bad? Any ideas or help? I was also told to show you this part of my dss.exe scan that proves what I have said is true:

Does your graphics share system ram? Go to start, then run, then type in dxdiag (assuming your using xp/vista). What does it say your graphics is under the display tab? How much memory? Seems kind of weird, that it would all of sudden just start sharing memory though. Also, about 256mb seems like a lot to be sharing.

Start/Run...type msinfo32...look at last item visible in right-hand column.

How much physical memory is reflected?

Your issue also sounds like a shared ram issue. I have seen some computers that can use up to 256 meg of regular ram as video ram. Several sony computers come to mind.
The name says it all -- 59 and holding permanently

Wow lots of replys to my ram problem! Thanks everyone! I'l start by answering the first person first.
When I run dxdiag it says I only have 766 ram of memory and my display is using 382 of that.
I know I have 1024mb of ram cause I have two "sticks" of 512mb of ram each.

Ok As for the next question: When I run msinfo32 it says I have 765.56 MB ram

Ok and for the last person I have an Acer Aspire 5050 running Windows Vista Basic

Here is what I found on the displayed system info:

Well...I'd pull those two sticks and check them.

Total physical per msinfo32 should be dead on. I have two sticks in this system (1024 plus 512) and mine reads 1536. OTOH, if I use the number reflected on My Computer, I get the total physical minus the shared ram for onboard graphics.

784 minus 766 equals 16/18 for onboard graphics (variance due to rounding).

don't trust anything that windoze vista baby tell you about ram on a shared ram system

http://www.cpuid.com/cpuz.php

what does this say?

Video Chipset ATI MOBILITY RADEON X300
Max Shared Video Memory 256 MB


hint!!!!!!!!

766 + 256 = 1022

oldf@rt hit it

I don't know if that is what you needed to know or not. I also read somewhere that my video chip set can use up to 516 Mb of ram but that still does not explain why my system page is only showing 766 mb of ram.

Go into your BIOS...and disable video shared memory. Reboot.

In fact, you don't even have to disable it...just reduce the shared amount to 32GB. Save the BIOS settings. Reboot and see what is reflected on the My Computer summary.

for vista I would leave it alone, 256 megs is about right

adding another gig of memory will be better, but both your memory slots are full

best to optimize/streamline vista

might even get away with only sharing 128MB of video memory in bios if you disable all the eye candy that vista tries to run

No. Try not. Do... or do not. There is no try.

i have my system set to preformance setting any way. I don't care about all the "pretty" "bells and Whistles" So how do I reduce the Video memory in bios?
Thanks again

Follow manufacturer's instruction for entering the BIOS, these vary according to manufacturer. Should be contained in your owner's manual, among other places available.

Enter the BIOS/Setup.

Each BIOS can be somewhat different...but there should be a screen available which reflects various component settings. One of these will say something like "shared memory" or "memory allocated for vide".

Click on that item, thus allowing you to change the setting. I would allocate no more than 32GB for video. Unless you are gaming, 32GB is more than sufficient for routine computer tasks these days.

Most video cards express extreme amounts because they are targeting gemers and gaming stresses a video card in the manner that the more memory, the better the card performs at rendering graphics for the game.

Once you change the memory allocation for video, follow instructions to get out of the BIOS. Be sure to save all settings (press F10) as your last step. System will reboot.

Thank you to everyone for your help! My system is running fine now. I set my my video to 128 and my system runs better now (even gaming) then before the trouble started.

thanks again to all who helped,
Mindy

The new Windows Display Driver Model (WDDM) has changed the way that memory is reported throughout Windows Vista - so the numbers won't be the same (or in the same places) as they were in XP. Go to this link and on the right hand side will be a download for the full Word document: http://www.microsoft.com/whdc/device/displ...hicsmemory.mspx (direct download link to document: http://download.microsoft.com/download/9/c...phicsMemory.doc )

If you can stay awake while reading it (I just managed to finish it not long ago) page 7 has details on how to calculate the graphics memory. Since CPU-ID shows both 512 mB chips - you've got 1024 mB of RAM - but it depends on what's being used for graphics (and how it's being used) as to what your exact numbers will be.
