Hi. Just to confirm we do not need to root the s3 in order to overclock to 1.8mhz. Am I right?
Hi Vince, you can directly flash the kernel via Odin. No need to root your phone.
Hi Alvin, thanks for your information. I have managed to do that. But how can I check whether now my processor can run at 1.8ghz?
Theres an app u can download to check n see how fast your phone is. Its called speedtest.net u can find it in the play store for free
correct if i’m wrong. i tested speedtest.net as you advise but as i tested it, speedtest.net is only check how speed your internet connection.
yah! you ryt……
Hi vince, do u just checked on the PDA via Odin to flash the kernel only? People commented that Ninphetamin3 custom kernel have bugs ,camera not working properly, u hav the same problem? Advise?

Guys, I found newer version of odin3 (3.07) and ninphetamin3 (1.2.2) and I can confirm these are working very well with no camera problem and no issues at all so far, overclocked to 1.8ghz. However I am not getting a higher score on benchmarks, they are the same. I cant say I have noticed much difference in performance either.

I just updated my Samsung Galaxy SIII to Android Jelly Bean 4.1. I tried to overclock it by following the instructions above carefully. But it seems that I broke my device. After rebooting, only black screen appeared and blue light is shown from LED notification light. I didn’t root my device. Please help.
How you fix it? I’m in the same situation.
I fixed it, just re flashing with the ROM I had.
