[FIXED] Anyone has this problem too?!?

[sjj]

I had a topic about the java speed on E2, I could not find it, so I made a new one...

The problem:
My E2 is overclocked to 624mhz... While running java applications, like jbenchmark 3d, the speed was very good until I press any buttons on the phone... If I let the benchmark run without pressing any buttons, it can run at about 11fps in both game test, but, if I press a button, it will drop to 7fps, which is the speed of a 312mhz E2!!! And I can't possibly play a game without using any buttons... BTW, I just re-flashed my E2 to ROKR Ultimate just to fix this speed problem ...

Try this on your phone:
After overclocking to 624mhz, run jbenchmark 3d and take note of the fps in the 3d game test, however, while testing DO NOT PRESS ANY KEYS! Set the display timeout to 2 minutes...
Run jbenchmark 3d and press some buttons when the test starts...

Pls reply and tell me the fps u get and give me a solution if you can...

SOLUTION!
Disable keypad backlight...

I got the same, sjj.. But i dun think its only E2 hav this problem.. When i testing E2@624mhz and 6300 (live compare), with pressing keypad the E2 got about 2400-2500 (i forgot the real number) and 6300 got 2200.. Without pressing any key, E2 got 2900-3000 and 6300 got 2700.. I tested it with SP Mark06 Java..

A Nokia also have this problem??
But I remembered there was a time when I just flashed to ROKR Ultimate and it can run at full speed even after pressing a key...
After a few weeks, the speed dropped...

So now I re-flashed and still face this problem! :'(

Not sure.. I always got this problem..

Multipress support is an expensive feature, I mean, a multipress kernel is slower than a 'unipress' one.  That's why you get lower performance in benchmark if you press any key.

[sjj]

If its the multi-key causing the problem, then I want to disable it... How to do that?

[Taurnil]

flash a non-multipress kernel.
but... your rokr will suck at games, btw xD

Another observation, when the phone is not overclocked(312mhz) there is no performance decrease when I press a key...

However, on 624mhz, when I press a key, the performance will drop to the speed like a non overclocked phone...
So, I think there is something wrong with the overclocking that causes the speed to drop whenever a key is pressed....

Run a processor benchmark on your PC - don't touch anything. Now run it again, tapping keys and moving the mouse. Surprise!!!

The processor has to process your keypresses along with the rest, doesn't it? The smaller the processor, the bigger the impact of inputs into the system - so on your PC the difference will be minimal - but it will exist - while on the phone...

When I let go of the keys the performance still would not go back to normal speed...

Not immediately. The figures you gave are OK, don't worry. Think about it this way: you're giving your phone extra stuff to process. See if you can do more things at the same time with the same efficiency.

All of us are wrong, I found out something new today...

1. Overclock your phone to 624mhz
2. Start the realtime CPU/RAM Mpkg
3. Make sure the CPU speed is at 624mhz
4. Press any button
5. OMG!  WTF THE CPU SPEED DROPS BACK TO 312 MHZ!!!!!!!!!!!!!!!!!
6. Quit the app and try again, the cpu speed will drop once you press a button, this happens in most of the other applications/games too... Making the overclocking almost USELESS

Someone pls help me fix this!! I'll reward you with some games(unreleased ones!) if you can solve it...

Yeah,I've noticed that several days ago.It means that our E2 is unstable.The CPU can't handle the keypressed.It's useless if we do overclocking..It just makes our battery drying faster.

so.. thats mean.. OC just run when our phone on standby mode.. when we press a button.. it will become a normal??
