For some reason Geek bench didn't want to load the web pages (server issues?) but i'm pretty sure it uploaded the runs to the GB servers.

I know it can go further also (There is a 3,1 cMP on YT running at 3.6 GHz)

Overclocked with the OS X utility and warm rebooted into windows or did you use SetFSB in windows and attack the clock gen directly from windows?

I did the latter when I overclocked my MP2,1 in windows a few years back http://valid.x86.fr/db35bu

for a while I was in the top 15 highest overclocked X5355s :D

May I recommend grabbing some 1333Mhz Xeons and BSEL+VID modding em for maximum overclock?

I sourced some X5350s for this reason to try and make a 3.33Ghz MP2,1 :)

Attack the clock gen, ill need to get another SSD for MacOS. If i'm not mistaken ill stick as long as the machine isn't shut down (Switching between OS'es?)

I know this is the case for the OS X app I dont know about setFSB I guess the only way to find out is to set a clock speed reboot and see if it stuck?

(I know on the MP1,1/2,1 it goes away even in OS X when ya reboot)

the 3,1 doesn't lose an overclock during reboot, full shutdown is required to lose the overclock.
In fact, after you overclock you want to reboot so that you fix the time clock issues as the OS clock is sped up in accordance to the changed FSB which is what makes a lot of benchmarks not reflect a performance boost due to elapsed time calculations.
