Hello
Recently I decided to make one old school rig with spare parts I have ( all of them working). So I used my old Asus A8N - SLI motherboard with 2 Asus GF8600GT (Silent EN8600GT) 512VRAM each and 3 GB DDR400 A-data (2x1GB +2x512 MB - all with same clocks and from same series) and Athlon 64 X2 Dual Core 3800+ @ 2.00 GHz. Everything works great, Win7 x64 Ultimate installed. The issue is that in BIOS there is listed that I have installed 3072 MB RAM, but usable 2560 MB RAM. Because of that Windows ofcourse shows 3GB (usable 2.5GB - the other 512MB is hardware reserved). I searched through google and some forums, and someone mentioned that this is normal because the SLI I used. Because thats my first time I use SLI, want to ask is that normal and can someone explain me if its normal, why it is normal
?
P.S. In my BIOS the options about S/W and H/W over 4GB remapping are enabled, the memory is set to 400Mhz with correct timings according CPU-Z and Everest Ultimate 5.50.
Best regards!
