increase speed from u-boot

Memocan
Hi ;

i have tiny6410 with 2GB nand (MLC2) . i try to increase clock speed of
s3c6410 to 667 MHZ , but on android linux kernel , bogomips is reduce.

normaly , linux android kernel says 530 around bogomips

when i set 667 MHZ from u-boot it says 370 around ?

what am i doing wrong ?

The bogomips for ARMs are always the half of the CPU clock frequency. So,
your 370 bogomips for the 667 MHz core clock looking reasonable. 530
bogomips will suggest 1.06 GHz core clock.

Its impossible because s3c6410 work up to 800MHZ with correct voltages.

I guess it depends linux kernel. (arm9.net) realy fucked up kernel , i cant
find anything in regular place. Another thing they also say  we implement
android 2.3 , but its fucking slow . because they dont implement 2D and 3D
drivers on android , so its not important to say to folks we are first.
What im doing slow android. 

Right now im realy hitting my head to wall,why  im not buying another 6410
products.
