My windows 7 64bit PC which I have recently built says that there is 4gb of RAM on my system (which there is) but only 3.5gb of which is usable. I have an 880GMA-UD2H giga-byte motherboard. When I enter the BIOS I can't seem to see a memory remap option, although maybe I've just missed it. Suggestions?
have you tried this press windows key + r type msconfig > press enter > go to boot tab and click > then click advanced options > in the boot advanced options pop up make sure the maximum memory is un checked (no tick in box) > press ok and reboot if a pop up tells you to:) *see png at foot of page*

Check BIOS settings
The problem may occur because some BIOS settings are incorrect.
Enable the memory remapping feature
Check the BIOS settings to see whether the memory remapping feature is enabled. Memory remapping gives Windows access to more memory. You can enable the memory remapping feature in the BIOS by booting to the system setup. See the User's Guide for your computer for instructions on how to boot to system setup on your computer. The name for the memory remapping feature may be different for different hardware vendors. This can be listed as memory remapping, memory extension, or something similar. Be aware that your computer may not support the memory remapping feature.
Change the AGP video aperture size in the BIOS settings
Check the BIOS settings to see how much memory that you have allocated to AGP video aperture. This is the memory that the system is sharing with the video card that is used for texture mapping and rendering. This memory would not be used by the system, because it is locked by the video card. You can adjust the AGP video aperture size in the BIOS. Standard settings are "32MB,""64MB,""128MB,"and "Auto." After you change this setting in the BIOS, restart your computer, and then check the usable memory. You can test each setting to see which offers the best results.
The following sections offer additional information about memory allocation as reported in the Resource Monitor, describe the terminology used, and offer additional information on Memory reporting and memory limitations in Windows 7.

Physical memory allocation in Windows 7
The following shows how the Resource Monitor categorizes the memory currently installed on a Windows 7-based computer.
Memory allocation Description
Hardware Reserved} Memory that is reserved for use by the BIOS and some drivers for other peripherals
In Use} Memory that is used by process, drivers, or the operating system
Modified} Memory whose contents must go to disk before it can be used for another purpose
Standby} Memory that contains cached data and code that is not actively in use
Free} Memory that does not contain any valuable data and that will be used first when processes, drivers, or the operating system need more memory
Note To view how the installed memory is allocated in Windows 7, follow these steps:
Click Start, type resource monitor in the Search programs and files box, and then click Resource Monitor in the Programs list.
Click the Memory tab, and then view the Physical Memory section at the bottom of the page.
Memory status in Windows 7
The following defines the Resource Monitors current reported status of the installed memory on a Windows 7-based computer.
Memory allocation Description
Available} Amount of memory (including standby and free memory) that is immediately available for use by processes, drivers, and the operating system
Cached} Amount of memory (including standby and modified memory) that contains cached data and code for rapid access by processes, drivers, and the operating system
Total} Amount of physical memory that is available to the operating system, device drivers, and processes
Installed} Amount of physical memory installed in the computer

also have a look at this program for ram by passmark PassMark RAMMon - Identify RAM type, speed & memory timings
Unfortunately the box was already unchecked and I can not find a memory remapping option OR an AGP video aperture changing option. Does anyone know if my motherboard is compatible with either of these or a way I can find out? Any other suggestions?
I has half a gb (the amount not used) under hardware reserved in resource monitor. Anyone know a way, in or out of BIOS, of changing this that's not already been suggested? I really appreciate your help guys, thanks a lot.
if you could see the remapping settings that would help i no you have tried this but i thought i would post for others if they read https://www.sevenforums.com/tutorials...ndows-7-a.html
