I just recently built a new computer. My issue is that windows is not detecting my full amount of memory. It is only showing 2558MB. I have 4 gigs installed and it is shown in my BIOS. Any help?
 
Sorry this is what I have.

EVGA 122-CK-NF68-A1 LGA 775 NVIDIA nForce 680i SLI
Intel Core 2 Duo E6600 Conroe 2.4GHz
CORSAIR Dominator 4gig DDR2 1066
EVGA GeForce 8800GTS 640MB x2
 
You need to add the /PAE switch and possibly the /3GB switch to boot.ini for Windows to use the 4 GB:



I cannot remember the exact syntax...and am away from my server to get it...but someone here can probably help with that. Make sure to backup the boot.ini file in its current state in the event of disaster.

All of that seems confusing...but I will try it....thx for the help...I will post back here to tell if it worked.
 
How to backup & edit the boot.ini file:


My boot.ini from server with PAE switch:
Code:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003 for Small Business Server" /fastdetect /NoExecute=OptOut /PAE

Of course sub WINDOWS="Microsoft Windows XP Professional"
for Win2K3. If you backup your boot.ini you will have no problems.

...and from that TechNet article above:

Code:
Operating system 	Physical memory limit without /3GB 	Physical memory limit with /3GB
Windows Vista 	4 GB 	4 GB (no effect)
Windows Vista, Datacenter Edition 	128 GB 	64 GB
Windows Server 2003, Enterprise Edition 	32 GB 	16 GB
Windows Server 2003, Enterprise Edition SP1 	64 GB 	16 GB
Windows Server 2003, Datacenter Edition 	128 GB 	16 GB
Windows Server 2003, Datacenter Edition SP1 	128 GB 	16 GB
[b]Windows XP (all editions) 	4 GB 	4 GB (no effect)[/b]

So forget the /3GB switch. Physical Address Extension should be all you will need.

I appreciate all your help wahnula but I had 1 more question. What is it that I would actually have to change in my boot file to have windows be able to address all of my physical memory?
