What's wrong with the RAM?
I have MacBook Pro (lastest one-Snow Leopard installed)
Using Boot Camp, I install Windows 7 build 7600 Ultimate 32 bit What I know, I have 4GB RAM but why, in the system properties, it shows that only 2.72GB RAM is usable?Why this is happening? I can't enjoy 4GB RAM for my works (e.g GAMES  )Any idea anybody? |

Windows x86 never displays over 3.25Gb of RAM, and it sounds like your graphics adapter is sapping the rest. If you want to see correct memory reporting then use the x64 build instead...

I used to install the x64, but it shows only 3.72GB
By the way, my graphics card is integrated nvdia 9400GM 256MB *Additional info, i also see my friend's laptop using windows 7. same results as me (2.72GB usable RAM, although 4GB RAM are installed) |

as qdos replied your graphics card is intergrated so it "steals" 256mb of ram x86 is restricted by licence on ram usage, hope that helps

Windows x86 can and does address 4Gb of RAM, but won't appear to as it under reports the available physical memory... here's one of the many articles you'll find strewn over the internet regards the same...

from that article, x86 architecture doesnt address that final 1GB at all, thats reserved for the IO memory address....thats memory hole problem for all x86, and not particular to any windows x86. What is not discussed is if you have integrated hardware as on most notebooks....would the extra 1Gb be used for the IO devices.... from the OP, it doesnt look like it..... |

Then it's a good reason to go to x64 bit computing...

What is wrong with this pc NOW? I was on a computer game and when I got off the resolution was huge. No big deal, it happens sometimes and it's nothing that a reboot doesn't fix UP UNTIL NOW. So I reboot the pc, but it comes back the same way. Plus my anti-virus is off (it does that sometimes too) but I can't put it back on. ... |

First off after doing the bios update I checked the system with just the original 2gig of ram - it seemed ok but a little slow. I then added... |
