Unreal Tournament and Serious Sam 2 produce similar results. Any advantage in processor frequency leads to a higher fps value. The FSB speed and memory timings also contribute to the total result.

Summing it up, we should acknowledge that the memory tests we performed with the FSB overclocked to 250 and 257MHz did not bring any extraordinary insights. The only interesting thing from the practical point of view is that at 275MHz FSB it is often better to use 336MHz memory with aggressive timings rather than 440MHz memory with RAS# to CAS# Delay and RAS# Precharge set to 3. However, the performance gain is very small in this case anyway.

As for using DDR500 SDRAM in the synchronous mode during FSB overclocking to 250MHz, we really doubt that it makes sense. This overclocker memory is much more expensive than ordinary DDR400 SDRAM, while the performance it provides is just a little higher than that of DDR400 SDRAM with 2-2-2-5 timings. The table below shows what difference between these two combinations exists in various applications.
