Just purchased an ECS N2U400-A motherboard and AMD Sempron 2800+ w/ fan. I also bought 1 GB 3200 DDR. Can I use that memory. I mean, 2800+ is FSB of 333 MHz and DDR 3200 is 400 MHz. I don't understand the FSB and its underlying importance. So would the memory and the processor running at different bus speeds cause any problems? Please help. Thanks.
