and im not sure how to check the speed so that would help out to thanks

Where are you looking at the "propertys" are you sure thats not the availible ram?

maybe thats the ram thats free/not being used.

I don't think it's possible for onboard video to take 512MB, but do you have onboard? Also how much RAM is detected by the BIOS?

after the update for the bios the ram went to 3.25. I use a 6800gt for the video card im not real sure about the onboard. The mobo is an ABIT ic7g

This is actually a common problem (which i thnk they fixed when intel moved to s775)

Under the current PC memory addressing, there is a memory area just below 4.0 GB which is reserved permanently. The maximum DDR memory support is actually about 3.5GB rather than 4GB. This limitation is caused by the current PC architecture in which the missing 0.5GB of memory addresses are reserved for PCI I/O space, AGP aperture mapping space, and other onboard device I/O space. Thus although the chipset datasheet may claim memory support for up to 4GB, the system actually only offers about 3.5GB with four 1GB DDR DIMMs installed. 32 bit processors only support 4GB of address space.
