Windows 7 64-bit RAM usage
Upgraded to Windows7 64 bit from Vista 32 bit. Added RAM to 5GB (reason
I upgraded to 64 bit was to get around the 3GB 32 bit limitation.) Now system shows 5GB but only 3.3GB available for use. Task manager shows 5.12GB installed, 3.326GB available or cached and 1.794GB "hardware reserved"(?). Is this 1.794 not available for software? If not, how to make it available for software? I really wanted the performance improvement of 64 bit and increased RAM. How do I get Windows7 64 bit to utilize the full 5 GB? System is HP running 64 capable 2.13 hz dual core Intel. |

Moreover, bear the following in mind: 1. 64-bit Windows will provide a performance benefit *if* you are running 64-bit applications, and do next to nothing for you if you are not. Since there are very few 64-bit applications yet, it will do very little for performance. 2. Increased RAM will provide a performance benefit *if* you are running applications that make use of that much RAM. 3. I'm running 64-bit Windows7 Ultimate with 6GB of RAM here. At the moment, I am using just under half the RAM (2942MB, and that's the typical amount I use). I'm in favor of running 64-bit Windows, since it gets you prepared for the future. But don't expect a performance improvement from it now. -- Ken Blake Please Reply to the Newsgroup |

Windows 7 64-bit RAM usage
I see "Installed memory (RAM): 4Gb (3.84Gb usable)" on my new 64-bit Win7-
64bit 'puter. If that means anything. I didn't know it was Win7 or 64-bit until I took it home. I was sold on the white key caps. Vaio laptop, with tax, $720. I have jumped through a few hoops ever since. Need to brush up on file permissions, etc., etc. Best, Andy |

Windows 7 64-bit RAM usage
Hi, Andy.
Did you read my Reply to Bob Costello, the OP in this thread? Another way to check if you have 64-bit Windows installed is to look in Windows Explorer. You should see a folder named "C:\Program Files", of course. Do you see ANOTHER folder named "C:\Program Files (x86)"? If you DO have the folder with "(x86)" in the name, then Windows x64 is running. If that second folder does not exist, then you are running 32-bit Windows - EVEN IF you have 64-bit hardware. If you need an explanation of this, please post back. RC -- R. C.

I am definitely running 64 bits. Did a clean install and it shows it is running 64 bits. Board is ASUS Tek Leonite 5.00 and the bios is Phoenix Tech LTD 5.09. The computer is an HP Media Center with 2.13 GHz Intel Core 2 HP-Pavilion RT680AA-ABA m7747c. Sounds like it is a BIOS limitation. I see no option in Bios to change anything related to this. |

If you look at "System" window in your control panel, what exactly does the "System Type" say? If it doesn't say "64-bit Operating System" then you're not running 64 bit, no matter what hardware you have. To get 64 bit, you have to install Win7 with a disk that says 64-bit on it. The fact that your memory says "only 3.3GB available for use" sounds very much like what a 32-bit system would do. Sam http://i37.tinypic.com/2ykhoww.jpg Andy |

In general, the only ones you are likely not to be able to run are a few utilities. 2.

You can run 32-bit applications under a 64-bit operating system, but you can *not* run 64-bit applications under a 32-bit operating system. Hm, that's interesting. I used to be involved with Unix application programming and when we moved to a 64-bit OS there, several of our old apps did not work, mainly because integer variables were the size of a computer word, 32 bits, and when the apps called system routines there was a problem; the new system routines expected 64-bit integers. After rebuilding the apps in the new system, the problem usually disappeared. Be that as it may, I'm glad I stumbled on your post in time before deciding which Win7 I should go with. I'm buying a new HD for my laptop that I will use with a clean install. That way I can still have my Vista setup, just in case. ;-) |
