Flashing will erase your internal sd. Make first a backup if you need it!
My releases are previously tested but not garanted to work . Flash and use at your own risk!
Use Rockchip Batch Tool to flash the firmware, use Restore button.

Seen using the overclocking 21 days. graphics no problems.The problem is a fever.
Personally, the CPU clock 300-1800 / / 1600 or 1200 should be removed.
Changed steps and raised gpu 798mhz voltage a little more. This should fix random benchmark artifacts on screen.
CPU GPU DDR
[312mhz,850mV] [133mhz,925mV] [200mhz,950mV] SUSPEND
[504mhz,875mV] [200mhz,950mV] [720mhz,1200mV] NORMAL

Updated main rom with kernel fix.
admin, it seems i got a problem when trying to edit my topic.

This looks like great work. Waiting for my new tab to arrive in the next few weeks and think about adopting your work for it. Where can I find some of your sources?
I am especially interested in the kernel sources. I never got a Rockchips based tablet that really does power management through controllable DC/DC converter chips. Most times the PWM or DC/DC drivers where fake.
But we'll see with the next one.
First I appreciate your work here, and I think it is fantastic that you released such a cool rom.
But one question..
We should all respect the rules of the GPL, right?
I have looked at your overclocked kernel, and one thing is unclear to me. How can it be that the kernel build machine string is root@five-server2? This is exact the kernel build machine string from here http://www.arctablet.com/blog/forum/fnf-ifive-tablets/rom-fnf-ifive-mini3-android-4-4-2-kitkat-custom-rooted-firmware-based-on-v2-0-1-20140105/. This seems to me, as I understand it, like the string from the stock kernel, okay a little bit younger.
Did you compile the overclocked kernel by yourself, or did you patch it? I'll only ask because, if you compile it by yourself, you should release the source as stated by the GPL, if not and you patched it through RKPatchomatic or something similar, you should mention it and give credits, that would be fair.
BTW. if you patched it, you should keep in mind that the clock-data is not patched, and if the normal delimiter in clock-data is present, it could happen that the kernel states to have 1.8GHz, but never reach this frequency.
Astralix and JochenKauz,
First, thank you for appreciating my work.
Regarding kernel source. So far as i know, there is no rk3188 kernel source released for our tablets. I wish i had it and being able to share it with you.
As you have realised, my oc kernel has just been patched.
The only reference i have is the released source kernel for mk908 been posted here a time ago:
As you know, rk3188 sticks and tablets have lot in similar, specially regarding arm dvfs frequencies and voltage tables.
You could take a look in arch/arm/mach-rk3188/board-rk3188-ds1006h.c. There you will find what you are looking for.
Once you properly search in stock kernel, you will get this:
Marked green=cpu table
Marked blue=gpu table
marked yellow= ddr table
It is not the easiest way since working with binary maybe give you headache but it does seems to work. I do not recommend it due to high risk of going wrong when editing.
Benchmarks gives better cpu and gpu scores and monitoring frequencies does seems to work.
I hope i helped you. BTW can you give me more information about RKPatchomatic?
EDIT: rkpatchomatic tool does just the same job made easier :D. As i see, it does search for those voltages in stock kernel but the script is not updated, since ddr table search wont work on 4.4.2 anymore since its value format has changed in new kernel. :b
as I have seen, you found on xda the RKPatchomatic on your own.
The problem you sometimes have is, that in clock-data another limiter is set, and you can patch the frequency table, but it won't work. I have seen this on RK3066 Genio and on a RK3188 Pipo S3. In both cases it does not work correct and only shows a maximum of 1800.
Other problem is, that you loose a frequency step, cause you cannot extend the table with more steps.
I hope that we get in a few days our new RK3188 Odys Iron tablets for our crew, and then we will start our custom kernel project for RK3188, perhaps we could get a custom kernel for iFive too.
