| 742253 | 2009-01-26 22:24:00 | Asus N50Vc Sticker4GB RAM Belarc reports 3072MB RAM - apparently short by 1GB. This is a new incredibly stupid thing laptop makers are doing. Stuffing 4GB in them and then installing a 32bit O/S. You won't get the full 4GB unless you have a 64bit version of Windows. Regardless which flavour of Windows it is. |

| 742254 | 2009-01-27 00:28:00 | If the graphics card has its own memory... i.e. it is not allocated from the installed RAM then it doesn't affect how much RAM the Windows OS sees. If the graphics card uses RAM as its memory source then yes it would affect how much RAM you see in the Windows OS. So if you had 4GB of RAM and your graphics card uses say 256MB that would give you... 4096 - 256 = 3840MB Windows will only see 3300MB so you would still "lose" about 540MB Please correct me if I'm wrong... The other scenario would be... Windows only sees 3.3GB of RAM less your 256MB for the graphics card which will leave you with... approximately 3040MB of RAM. Having said that... why in the world would you want 4GB of RAM for laptop? |

There is a total 32bit address space of exactly 4GB. Windows uses this space to address the system main memory, the graphics memory, the bios, any mmap access to hardware, and any remapped memory holes that point to other things. The result is that 32bit windows will only see a little over 3GB of main memory (because all the other junk uses up the rest of the address space), unless you're using a pre-SP2 version of XP with the PAE boot switch. |
