2.50GB usable out of 3GB?

post #1 of 24
Thread Starter 
i dug my old DELL rig out of the closet for kicks and i put windows 7 on it and just had a look at system info and it says installed memory 3GB (usable 2.50GB) why is it doing this? i got a dedicated graphics card so it shouldn't be sucking 512MB ram away from the ram. any ideas?

Was it 2.5 or 3.5 for the max a 32 bit OS can recognize?

Is it Window 7 64bit? If 32 bit you will only see 2.50gb. But 64 bit you will see 8-12gb depending on your system.

I suggest that 0.5Gb is allocated to dealing with your graphics card.

lol all 4 of mine is detected and used in 32bit win7 home premium. I was going to ask about the max limit, but being it is from 2007 that is probably not the issue..

nahh 32 bit can see up to 3.5 gb, its windows in general, taking a percentage for GIU etc. and onboard graphics, theres nothing to worry about.

BS. Windows 7 32bit can see full 4GB RAM and not a megabyte more, I had 32bit Vista with 4GB RAM and it saw the whole amount. Only XP and older 32bit operating systems can't see above 3.5GB RAM.

@OP check BIOS for IRQ settings for the card, it's probably allocating some RAM for the card just in case it runs out of VRAM through some BIOS setting. If you can't turn this off, set it at the lowest possible option (like 32MB tops).
