My Hardware System is 64 Bit capable.
I use the 64 Bit Version of Windows-7 Pro.
Windows-7 reports only using 3G of the 4GB's installed Memory.
Belarc reports 4GB's installed Memory.
CPU-ID reports 4GB's installed Memory.
Intel lists my E6550 CPU as 64 Bit.
Do I have something set up wrong?

If this is the same laptop as in your specs, then there isn't much you can do unless there is a memory remap option in the bios (doubtful). From what I can see it has the Intel 945 chipset on it and it only supports up to 4 GB of memory, which as a result without the memory remap option is what is happening in your case. This should help explain it some (says for Vista but the same applies to Windows 7),
The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed
- The chipset must support at least 8 GB of address space. Chipsets that have this capability include the following:
- Intel 975X
- Intel P965
- Intel 955X on Socket 775
- Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU.
- The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.
- The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
- An x64 (64-bit) version of Windows Vista must be used.
The Profile is an AIO Desktop.
I have looked at those items that I think I know about but I am stymied.
When I ran Vista on the same machine, it used all 4GB's.
Any advice would be appreciated.

Just in case I took two 2GB Memory Modules out of my other Profile and installed them in this one.
It did not make any difference, Window-7 still reported only 2.99 usable.
I seated the Modules and restarted the System twice.
I also cleaned the thing you insert them into with Air just in case.
I reran the Windows assessment, no change.
I removed the ReadyBoost Drive, no change.
My System is very generic and there are not a lot of options in the Bios.
Does anyone else have any other Ideas?

My System is a Desktop All-In-One.
It only supports 4GB's of memory.
I do not want to use memory beyond 4GB's as the System cannot / does not support that much.
I'd just like to use the 4GB's that is installed.
I want to use Windows-7 NOT Vista.
I have 64-Bit Versions of 7-Pro and Vista Ultimate.
Your feedback is appreciated.
Best regards,
Mike Lynch
Are you sure that the full 4 GB was available under Vista? Reason for asking is that when Vista came out it reported 4 GB of memory (on a system that only supported up to 4 GB) the same as what you are seeing in Windows 7. When Service Pack 1 for Vista came out this happened,
Windows Vista SP1 includes reporting of Installed System Memory (RAM)
I'd be willing to bet that you still only had the same 3 GB available in Vista even though it showed all 4 GB.After you install Windows Vista Service Pack 1 (SP1), the memory (RAM) value reported by Windows Vista may increase if the following conditions are true:
- The system BIOS has reserved physical memory for graphics or for other peripherals.
- Your computer has more than 3 GB of system memory installed.
This change occurs because Windows Vista with SP1 reports how much physical memory installed on your computer. All versions of Windows NT-based operating systems before Windows Vista Service SP1 report how much memory available to the operating system. This change in Windows Vista SP1 is a reporting change only.
As I mentioned previously (and in the first Microsoft link I posted), unless there is a memory remap option in the bios there is nothing you can do.
Can you post a picture of the colored bar in Resource Monitor > Memory tab. Something like this:
From a quick glance, my guess is you were seeing Vista report how much memory was installed, not what was usable.
Are you using a dedicated video card? Because if you not, then windows is more than likely using that 1GB of RAM as shared video memory. If you can, borrow someone’s video card to see that lets you have 4GB useable.
Hope that was helpfull :)
