In the days of the socket 939, it was a known fact that the setting "Command Rate" made a big difference for the memory. Then came the Core 2 and this setting just disappeared from the scene, until shortly after the processor's release. Enter nVidia and their 680 chipset. There you had the Command Rate again, was it the reason why it performed a little bit better under games? There was no way to find out.

Now that the P35 chipset has been launched, there's finally the possibility to change that setting in the BIOS and xbitlabs has not wasted the opportunity. The tests they conducted showed that by setting Command Rate to 1T, performance increased slightly (by 0.5% at most). So, on an Intel platform, this setting is not a useful one. More obscure ones, like Transaction Booster, help more in increasing the system's performance (just 1%, in this case), although it actually works only with low memory frequency settings. But even limited as it is, it's better than Command Rate.

Besides the influence of Command rate and Transaction Booster they checked if there was a performance drop when Asus P5K Deluxe changed Strap as the FSB frequency scaled. And it appears that it's not affected like Asus mainboards based on the P965 chipset. All in all, quite a different beast.
