What does the BIOS setup say about the amount of memory?
What does memtest86 (free download from www.memtest86.com) say about the amount of memory?
I have 3 gb of ram installed on my windows xp pro machine, but in the task manger it shows only 1.5 GB being allocated. Now, i've heard from a number of sources that video RAM installed on the card also counts as allocatable ram. I have two video cards, an nVidia 8600 gt, and an nVidia 8800 gt, both with 512 MB video RAM, plus the same guy also said something about the PCI cache also counting in. And to add to that, any ram over 3 GB isn't shown in the task manger anyways because it is reserved by windows.
so here's what i was thinking about how the ram count added up:
1.5 GB video ram usage (including pci cache)
1 GB system usage
1.5 GB left for the user
1.5 gb of ram is left unallocatable
can someone who really knows help to clarify? this is just an odd issue that i have been trying to figure out for a couple of weeks now. i dont know whether or not i have come to the right solution and would like to know.
