 p.1 #13 · 4GB Computer --Vista only sees 3GB | |
A lot of info, some good, some kinda right, some just wrong.
Windows (32 bit) will only allow 2GB for any one application. So, even if you get all the ram to be seen...you will not be able to use more than 2GB (probably less due to PS only allowing a percentage to be used)
32 bit windows will not allow more than 2 GB of contiguous memory. So if PS asks for a 2.5 GB chunk of memory, windows won't give it, but if PS asks for 5 half GB chunks, it will get it. JAVA programs are problematic if they demand more than 2 GB, because JVM demands contiguous memory.
You can modify how Windows maps memory by using the PAE switch. It's been five years since I did it...but here is a safer appproach. (It can make your system unbootable - or unstable with certain memory configs) All you need is notepad to edit your Boot.ini file located at the root of your OS drive. (usually Drive C)
Yes you can, but Vista does not use the boot.ini, it uses a BCD file. To add PAE in Vista, from a cmd line, type: BCDEDIT /SET PAE ForceEnable
It has been said. Your Video card is using the Ram and will not release it to the system. You may be able t oconfigure the video card to only take half of the 1 Gig.
Maybe. We don't know whether he has on board graphics or not. If he does, well shame on him for buying a large amount of RAM and a bigger CPU and not spending an extra hundred on a plug in graphics card with 256MB of it's on memory. Why any on board graphics card would use 1 GB is beyond me. High end gaming cards use and run fine with 512 MB of internal memory, so I would say its because windows needs the PAE switch, and not because of shared graphics memory.
Sort answer: You would need a 64bit operating system for more RAM than that as far as I know.
Unless you use a 32 bit server OS
Unfortunately they are cost prohibitive. Windows 2003 = Windows XP 64 and Windows Server 2008 = Vista Service Pack 1. Not exactly equal but the kernel shares much of the same code. Windows 2003 is a 32 bit OS that can see 4 gigs to I think 64 gigs depending on what version.
Not so. XP can also do this.
The sad thing is what a double edged sword windows success is. It allowed for a huge boom for other vendors of hardware and software and delivered a big economic spike, but at the same time, due to all those 3rd party vendors, it meant they all had to convert their wares to work with a 64 bit OS. We saw how crappy a job they did getting their drivers out for Vista.
