my currrent motherboard is a "FIC AD11 AMD 761 PC266 DDR MB 4X AGP" and i currently have a "256MB DDR PC266 PC2100" memory chip in my computer. I found a great deal on another 256MB DDR memory chip and I was wondering if my motherboard could handle it? I have a AMD Athlon Thunderbird 1.4GHz processor. But please tell me if I can put an extra 256MB DDR chip into my comp. Thanks.
