Check your motherboard documentation.
I will. what would it say? Why is that a motherboard issue? I have no RAID nor PCI controllers which could occupie the last 0.5GB.
I have 4GB GA-K8NN Ultra-SLI 4200+ SMP dual x86_64

actually I thought a 64bit system should not have this problem since it can address natively more memory than a 32bit system which can address only 3GB of memory.
It doesn't matter that you don't have any boards plugged into it: http://www.gigabyte.com.tw/Support/Motherboard/FAQ_Model.aspx?FAQID=4577&ProductID=1883&ClassValue=Motherboard Q: When system get full DIMM memory, why did the POST screen show the incorrect information? A: Due to standard PC architecture, a certain amount of memory is reserved for system usage and therefore the actual memory size is less than the stated amount. For example, 4GB of memory size will instead be shown as 3.xxGB memory during system startup. THE MEMORY SIZE WILL BE VARIED according to different chipsets, different VGA card used, DIFFERENT ONBOARD CONTROLLERS like audio and LAN etc, different add on cards used. You should see a similar message in the manual under "Feature Summary". In the English manual that's section 1-2, page 12. All that onboard stuff -- lan, Audio, disks, etc. Have to live somewhere in the memory map, so some RAM is "lost" if you have maxed out your RAM.
