Hello to all, I'm a newbie here! I have a problem with my motherboard, I wonder if anyone can give me a help. This is my system: [B]2 x Opteron 285 RAM Corsair ECC CM72SD1024RLP-3200 Windows XP 64x edition BIOS v1.05[/B] I tried to expand my RAM going from 4 to 6 modules of RAM (each module is 1GB). Of course I populated slots like in manuals reference: starting from DIMMA1 and installing modules in symmetric way for each CPU. By the way the BIOS keep reading only 4 GB instead of 6 GB. Then I wonder if the motherboard can read also 6 modules or it only can read 2, 4 or 8 modules... Can someone help me with this please? I wrote to technical support of Tyan but nobody seems to answer me :( If someone has any idea about that, please post a solution! Thank you very much for kind attention!
