I bought a new computer the other day. It came with 2 1-gig sticks. One of the memory sticks went bad, which pissed me off, but oh wells. Any ways I run vista ultimate 32-bit. And my motherboard has 4 ram slots. Specs say it is expandable to 8 gigs of ram. So when I went to replace my blown 1-gig stick I got 2 more in addition. When I put all the sticks in, totaling 4 gigs. I noticed it only pulled up 3. Also within BIOS it seems to pick up only 3 gigs. Is it possible that one of my RAM slots have gone bad?
It's possible that your bios will only support 3 gigs, but I think it doesn't matter what bit os you have installed to how much bios detects.
If the BIOS only reads 3 GB then one of the RAM modules isn't working and it's not related to the OS. Check your motherboard manual to see if your configuration is supported (notice double sided//speed factors too!). Maybe you didn't insert a module correctly? Maybe you need a BIOS flash?
Specs on the motherboard, or what? ...I have known mother boards to not play well with different sizes of RAM. (Like this one for example.) ...Another thing you can try is changing the order of the RAM. ...Sometimes that will cut you a break.
Might I recommend using Gentoos AMD64 if you plan on switching to a 64 bit system, it's great, well worth the effort of learning how to use if you've never used linux before. You might not want to ever go back to Windows.
32-bit systems can address 4 GB of memory, but 1 GB will always be reserved.
No more than 3 GB can be used on Xp or Vista...
It could also be a dead slot that made the original stick look faulty.
It's simple, Windows won't read more than 3GB on a 32 bit system. If you want the full 4GB with dual channel you'll have to go 64 bit.
I would wait a bit before switching, at least until a new line of intel processors.
i just have 3.5 gb of my 4 .. this is sad
