Actually., so how do one figure out whose is running as per the MHz? and is it doing any performance boost as per this benchmark?
But you can clearly see that my 1000 and 1100 have the highest numbers by far. (=fastest)

letho 250-800 (1000) ULV @1000
If you check my 1000mhz scores, yours is significantly lower than mine. (and yours match up to 800mhz result above by jaeezzy)

yeah was just redoing and making sure had nothing else running etc.
keep getting "CPU:NNET--error in opening file!" now when i try and run the test. :0/

Hmm. No idea what that error means sorry.
btw, I have just updated my post with 800mhz results also.

Hummm. By reading those scores one can reach a few conclusions so far on tendencies:
1) The N900 processor can actually do more general instructions/cycle than earlier Intel Pentium and AMD K6.
2) Floating point is way behind. Maybe FP instructions are being emulated. I wonder if there is any way to recompile the benchmark with NEON support (also, will it help)?
3) Memory and integer performance seems to increase linearly with OC.
Now I wonder. How long would the N900 sustain a stress test? Let's say: running superPi for 48 hours? ;-)

hmm.. now, i am also getting the cpu:nnet--error
Will try to swap it and see if it helps.

-mfpu=vfp gives the same results as -mfpu=neon. File is there, if anyone wants to try:
