4 Gig or ram- Only showing 3 gig
Hello,
Just read the longest post on this issue with no result so let try again. If i have 4 gig, only 3 shows, 750mb is reservered for the system. Doesn't that seem a little stupid? If i have 3 gig of ram, 3 gig shows in vista, here it has not needed to reserve 750mb. So why does the first scenario need 750 for the system, and the second does not? This would mean that the second does not have any ram for its system, same devices and os. I would have thought that both situations would result in having 750 stripped for the system. My old box, XP 256 mb ram all that was avaliable and did not need dedicated system ram. Does anyone have a straight answer for this? Yes i could run 64 bit os, but at the moment i want to get 4 gig running in my 32 bit environment. I tried the following switches with no change. 1. Reboot Vista to safe mode with command line 2. Run the command : bcdedit /set PAE ForceEnable 3. Run bcdedit again to verify the switch is added 4. Reboot the system and check whether the problem is fixed This is from the original post: http://groups.google.com.au/group/mi...dbc2867738d289 "LOL, I was scratching my head over that one too. By definition, a 32- bit CPU can directly address up to 4GB of memory. But apparently nearly 1GB of that is reserved for devices. So the most you can possibly see is 3.12GB in a 32-bit system. The way I read it, there is no way around it, no "fix" if you're using a 32-bit version of Vista. To see any more than 3.12 GB you have to be using a 64-bit version of Vista plus meet all those other requirements (64-bit CPU instruction set, chipset with 8GB address space, BIOS that supports memory remapping). That's the way I read it anyway. I think the DEP/ PAE thing is a whole different (but related) issue. " |
