Most mother boards will run at 400/333/266 etc. Beware tho, the system will run at the slowest speed ram you have installed. Some system will NOT run with different eam speed moduals. Tech is moving ahead so fast now its usually necesary to stick a new CPU,mobo,and memmory in a good case. Pay attension to your PSU. I recomend Antec True power 430 Watt unit.Regards
