overclocked kernel is here

[BrunoNRG]

well it is possible. Have a look at this http://www.anandtech.com/show/2468/6 but I have been running mine for 24 hours seven days a week and I have not got any problems, maybe I should remove the extreme overclocking kernels just to be safe

If that is the reason, I guess these CPU's have a very short life span.

One thing I find weird is that when everytime I connect the data cable from the d-link h7 hub I have to the usb port of the mk802iv, the device reboots itself just like it does when I try to run antutu benchmark... Can this two issues be related?

I've been running mine 24/7 for over a week on 1.9ghz BUT I left the CPU scaling down to the lowest frequency and not maxed out all the time. Perhaps that was the problem ??

I did the same, except when running benchmarks, which represents a minimal ammount of time. For normal use, I had the cpu set to 1.9max and 0.3min interactive governor, for benchmarks, 1.9 min and max performance governor.

I really do think the voltage is dropping too low, causing a reboot. i think you should try with just a basic configuration with just the power supply conected directly to the stick and usb mouse. Realisticly I could prove or disprove my theary by making a kernel that stops at 1416MHz but using the voltage of 1.8. As you say this frequency is stable, so by changing the voltage to the one of the higher clock, if it becomes unstable you have your answer

Can you make such kernel for me to test? I'm currently using an original sony psp slim, 5v 2amp, power adapter

[sam321]

Yes I will do it now

Thank you very much Sam, will try it know.

If with this kernel the device is not able to run antutu it will mean that the power adapter
is the cause of the problem, if it runs ok it's most likely that the cpu is the cause, right?

Edit: Just tested it, device rebooted at 1% on antutu benchmark... So I guess power supply is the problem. I will try to connect the psp charger directly to the device without going through the switch to see if something changes

Like I said before, the power supply I'm using is an original 5v 2000mA sony psp slim charger,
which apparently ain't enough for the mk802iv, what EU plug charger should I replace it with?

[sam321]

Yes thats right

[sam321]

try the power supply that came with the stick, I think what is doing it is the psp charger is not designed to supply 2a constantly

[BrunoNRG]

I finished running a benchmark with the charger plugged directly, without going through the switch, and it went fine... I can't believe that from the begining, the stupid switch has been the cause of the problem...

Now flashing 720p extreme overclocked kernel to see if it remains stable...

[sam321]

And that is why it is worth spending a few pounds on a multimeter as these problems can easily be ironed out

[BrunoNRG]

Finished with no problems, 18465 score, interactive governor 1920max 312min

I don't even know if it's worth to install SetCPU, and test performance governor and 1920 max / min frequency...

Edit: Well... I just tested the configuration I mentioned with SetCPU and, I have no words, but I have a photo:



I can't thank you enough Sam

[sam321]

I am glad that it is working now, I did not think it could be the cpu

Cool man , but my problem still exist like I wrote earlier about wat consumption on CPU test is more than 15W and CPU score is good but on GPU test is only 10W and score is very bad.

With Sam "my_kernel" results are the same (minimal worse). But I don't perform stability test yet - probably next week.

My Cozyswan S400/MK802VI Case Mod

Hello all. Thanks for the efforts, sharing and assistance. Has been ready and upgraded my S400 as suggested in OP. However, a few recoveries later and still unable to flash the "very extreme over clock 1080p" from Sam123. Currently I am on "720p very extreme" by Sam123, with it everything run very well but I am ready for the "very extreme over clock 1080p." Need help, do I need to include the very extreme kenel during the initial flash? By replacing the one in the NEOTV CR 1.0 Neomode Custom Rom 4.2.2? Tried just flash the kernel after initial flash but stuck at boot screen, black android with four color blinking lights.
Thought I would share my cooling solution, please see attached photos. My setup include a powered 7-ports hub, a 320 external storage, USB ethernet adapter with Logitech K400. My power hub act as a power center to all attached devices, including the blower for the case.
My Cozyswan MK809II and a CX-919 are on their way. May need your kind assistance in the near future. Onece again thanks for sharing.

please forgive me, i am new.

for sam (or anyone that may know) I have a few questions.

i have successfully rooted the s400, applied drivers correctly, now i am trying to flash with sam's kernel and i am stuck.

which tool are you using to flash the .img file provided?

is there any steps to follow for the cozyswan s400?

anytime I try RockBatchTool I get error loading the file, or no device found when I click the "switch" button, the device goes into flash mode, but i am not sure if I am missing some steps.

lol @ the heatsinks you guys are running. let's start liquid cooling it, and see how high it can go

this is the error i get loading the img provided. perhaps i am using the wrong drivers? i am not sure.
