    4GB RAM reported as 2GB in XP SP2 (32bit)

    I took a second look at some memory numbers, and with Memory Hole disabled, Windows is reporting EXACTLY the same amount of RAM as the BIOS. Since the BIOS does not know what OS will be loaded, I don't think Windows PAE mode is a factor here, yet. The BIOS would have to report more than 3.3GB...

    Actually, I think Microsoft introduced DEP, and it is implemented in software as well. You should find it if you right-click My Computer, then go to Properties, Advanced tab, Performance Settings, Data Execution Prevention tab. Also, Intel now has chips with hardware-enforce DEP, using...

    4GB RAM reported as 2GB in XP SP2 (32bit)

    Memory Hole! Memory Hole! Quick Summary: This a Memory Hole problem, but it's made worse with an AMD dual core CPU and an AGP video card with a lot of memory. Here is my understanding. I may be off, so please correct me if I am wrong: AMD CPU: One of the selling features with many of...

    4GB RAM reported as 2GB in XP SP2 (32bit)

    Tune in soon. Tune in soon. I've got it mostly figured out and can see about 2.9GB now. I have to go now, but I'll post the details soon. In the meantime, if you have a lot of memory on your video card, reduce the AGP Aperture Size in your BIOS settings to 32MB if possible!

    4GB RAM reported as 2GB in XP SP2 (32bit)

    I was quiet for a few days while I made sure that I had good RAM. I replaced all 4 sticks with new ones, and had the same problem. I tried a mix of old & new RAM (all identical brand etc.), and still the same problem. I tried 1117's suggestion of reducing VM, and set a static size of 200MB...

    4GB RAM reported as 2GB in XP SP2 (32bit)

    I personally use CAD and graphics applications that can use all of the RAM. I recently came close to using 2GB on a 3D CAD model of simple-moderate complexity, while running a graphics app, Outlook, and IE at the same time.

    4GB RAM reported as 2GB in XP SP2 (32bit)

    I think you always need some virtual memory since Windows or some programs are written to access a page file no matter what your settings are.

    4GB RAM reported as 2GB in XP SP2 (32bit)

    But if most system monitoring software running in Windows sees 4GB, and Windows only sees 2GB, wouldn't that mean it is a problem with Windows?

    4GB RAM reported as 2GB in XP SP2 (32bit)

    I hope I don't blow anything up! I tried 3 sticks as Kallex did, and Windows now sees 2.50 GB! At least there is some reproducibility. I also noticed that we both have the same CPU, same brand of motherboard, and we both have 256MB GeForce video cards. DimPrawn, what CPU, motherboard, and...

    4GB RAM reported as 2GB in XP SP2 (32bit)

    Me too Me too I have encoutered exactly the same problem. Windows only sees 2.00GB, even though the BIOS and different Windows system monitoring programs see 4GB. Why exactly 2.00GB??? My system specs: Windows XP Pro SP2 AMD Athlon 64 X2 4400+ ASRock 939Dual-SATA2 motherboard OCZ 4GB Dual...
