Warning W2523 - The memory bus speed exceeds the module speed rating. While most memory will operate at slightly higher speeds, this is not recommended. Consider buying higher rated memory.
Fix: If the memory bus speed always equals FSB for your system, reduce FSB speed. If the system allows you to run the memory bus speed at AGP bus speed or a lower speed, set it to use the lower speed. Alternatively, if you happen to have CAS2 memory, you can set it for CAS3 if the other parameters are within range.
