My Specs: GA-7VT600-RZ AMD Athlon XP 3000+ Sapphire RADEON X1650 PRO GFX AGP 8X - 512MB DDR2 SDRAM Sound Blaster X-Fi Xtreme audio sound card 2GB 2 x Koybe 1GB PC3200 DDR 400 LOW DENSITY RAM My Problem: The machine runs fine only the MB is reporting 1Gb in slot 1 and 1/2 Gb in slot 2. Does anyone have any clues? Is it a ram density problem perhaps? I would really like my 512Mb back. :D
