vista don't recongize 4 gigs of system memory
Hi
I am have the same problem missing 1 Gb of memory When I was running vista beta 2 32bit O/S, I could see all 4GB of memory, upgrade to RC1 Build 5600 I am now only seeing 3GB of memory. If I switch to vista RC1 64bit, I can see 4GB RAM on my system. No problem with my Bios, all set as suggested the problems is in this new build of vista RC1 I still trying to find how can I address/access this missing 1GB when using 32bit O/S?

I have 4G memory and running xp pro , only 3G was available. Using xp pro 64-bit I could see the full 4G of memory. It turns out that XP and ( VISTA 32-bit as well?) both use address's out of the 4G memory range to address hardware devices. Each hardware device you have means less addressable RAM. So I guess the answer is yes, VISTA has the same problem.... looks like I am going to stay with 64-bit then.

You have to correct that in your BIOS. How to do it will be in your owner's manual. Vista sees all the RAM the BIOS lets it see. He said his BIOS DOES see it On my Asus board in the BIOS there is "DRAM Over 4G Remapping" that must be enabled for the OS to see most of the 4G. Even with it enable I still lose a little bit and don't see the full 4G. There is a memory "hole" by design. Enabling the 4G Remapping moves it around the "hole" so the OS can see it. |
