Letho, a member of Maemo.org has successfully overclocked his N900 using custom Kernels to 1.0GHz. He did not do it in one go but tested by increasing to 650 Mhz and then with 100Mhz increments pushed the CPU to 1.0GHz. He adds in his post on the forums by saying:
“I didnt increase voltage. So far I’ve tested a lot of different applications that require heavy cpu calculating power and in short 10-15min bursts I’ve yet to notice any misbehavior @ 950mhz. The phone is now so smooth acting, but for how long?”
The phone was tested on over 1.0GHz speed but the stable speed according to him is just over 900MHz
Ni betul2 punya gamble....
Dapat phone bkn sekadar buat miss call atau credit sharing tp layor cukup2...
