| Re: [memory] P4c800 Deluxe & 4GB RAM It's probably a BIOS limitation. I have an ASUS board very similar to this one (P4P800MX) and had NOTHING but trouble trying to get it to work with 4GB of quality RAM. It would run only with the RAM underclocked, and IIRC, it gave the same measurements you see when it decided to work. I replaced it with an Intel board with the same components plugged in and all is well.
One thing you might try is to enable Physical Address Extension in the boot configuration (boot.ini) and see if that helps. You do that with the /pae switch in System Properties/Advanced/Startup and Recovery dialog. | |

Install xp 64bit or vista 64bit (any flavor) to have all of your ram recognized.

| Re: [memory] P4c800 Deluxe & 4GB RAM Besides video, there's other things that get mapped into the lower 4GB as well, such as the I/O for peripherals, pci bus, etc.
According to asus, the max mem supported by your board is indeed 4gb. I'm not 100% sure if it will let you use the actual 4gb of ram, even if you were to install a 64 bit os.
Some board have an option in the bios to remap all the i/o stuff above the actual installed memory.
Good luck.

| said by drrick :Hmmm... I'm beginning to wonder more about the memory my GFx card has and it's play in everything here. Thinking in terms of memory addresses, would it make sense that the total amount of memory attached to the motherboard is actually 4.5GB (4x1GB RAM modules + 512MB GFX memory)? That way, if the actual motherboard's cap is 4GB, then it might knock off that last ram module for a total of 3.5GB (3x1GB RAM modules + 512MB GFX memory). Hmmmm... No, that's not the way it works. Did you do what I suggested? | |

1 edit | you will need to buy XP Pro 64bit to see and be able to access all of your 4GB of ram, and your Video Card's ram is not accessible as system memory, do try and learn before you start tinkering with hardware. | |

Bloom County | Re: [memory] P4c800 Deluxe & 4GB RAM I will reiterate a 3rd time and point out that all the OP needs is a 654 bit OS for the OS to see all 4 gigs. | |

1 edit | Re: [memory] P4c800 Deluxe & 4GB RAM Then there is nothing they can do to make 4 gigs visible to Windows.
For some reason "P4 3.0GHz 800MHz FSB" did not click as it should have... | |
