Blacklist of locked Down Version´s of RK3188 CPU

[d33]

There was a compile error in the files uploaded which means the override wouldn't have worked, I've fixed and re-uploaded. Apologies to the few who downloaded already.

Or not so easy.... So far the only manufacturer that I know of that is not going to use the T model is Minix... are there others that you know of besides Minix.

Geekbuying is showing the Measy U4B as a non-T RK3188 and I chatted with an agent about this yesterday. I explained that the description on their site was not always correct and the descriptions of several other RK3188 devices had been updated recently to RK3188T. I explained that the only way to be sure was to open up the device and look at the chip. The agent assured me (although I am not actually assured, since the description also indicates an external antenna) that the description was correct and that they'd fix it if it was not.

Nice... I hope that it will work...

Btw, is it possible to get 720p kernel? Not now, but if this will work.

Re: Blacklist of locked Down Version´s of RK3188 CPU

For KitKat ROMs only

Here is a kernel that will output to DMESG the chip type and will overide the 1.4 GHz limit for T chips to 1.6 GHz

Kernel is 1.8 GHz (1.6 for T models), 1080 resolution, 720 DDR, 600 GPU

I have tested on a 'standard' RK3188 and can confirm this boots and outputs the message to DMESG but can't test the T overide

Here is link for kernels download:

and the thred where it was from:

http://www.freaktab.com/showthread.php?5412-overclocked-kernel-is-here

The AnTuTu and dfvs information in my previous message correspond to 720p 1.8ghz ram 1500mhz kernel.
Please don't pay your attention that kernels had been tested were compilled for sticks and didn't support my onboard LAN. The main idea was to test overclocking ability only.
Thank you very much for your friendly intention to help me

Not really wise to BET on something you paid actual money for (not monopoly's paper money),
simply go get the non-T, easy.

Or not so easy.... So far the only manufacturer that I know of that is not going to use the T model is Minix... are there others that you know of besides Minix.

I'm only asking for other people really... personally I don't mind paying for higher quality parts like Minix seems to provide. I already have a NEO x7 on the way for my own use.

Thanks d33, I understand you, but in case I flash my device with 4.2.2 FW + "old" Sam's overclocked kernels I have CPU dfvs tables with 1600, 1704, 1800... with increased CPU performance and total 19500+ score in accordance with AnTuTu (4.0.X), but at the same time something wrong with part of RAM and GPU performances, because I have:
Ram operation 2248; Perfect
Ram Speed 967; Low anough
GPU 2D 1398; Extremely Low
GPU 3D 2104 Extremely Low
Total 19507 Perfect

while mali_dfvs shows me this strange row:
128,179,223,297,297,446
where 297 is doubled and 446 is upper value, when I know it must be at least 597.
Probably there is something else we don't know about, like GPU and part of RAM (which seems to be as videoRAM), adjusting process.
What would you say about it?

[MINIX]

I think they are all the same chip... BUT some pass the stress tests and others don't, those that dont are locked at the lower speed and market -T, obviously some of the chips that pass the test will also go into the -T pile to make the numbers up when not enough failures, so you will find that some over clock and some don't...

Same as Intel, in the old days they were are fabricated as the fasted chip and then graded, the ones that qualified for the top speed were used as that, then they were graded down from there and sold as different speeds, but some basic models were able to clock back to an amazing clock speed as they had to use the best chips to make the numbers up of the lower speeds, some were not able to as they were the failed ones...
luck of the draw unless you use a quality manufacturer that has decided to use non -T's like MiniX, mine clocks to 1800 without an issue and is very fast you pays your money and you get what you pay for.... unless you were lucky

cpu-z app show you frequencies
for overclock T models you can run neomod 1.7 + SAM overclock
or neomod 2.1 + SAM overclock

Do neomod roms run on my CS968?

Kernels created with source code from before the T variant existed don't have code to detect and limit it, kernels created with source after the introduction of the T chip do have code for it. I explained in #329

Until we find a solution for our T models, is there any way to just overclock GPU and RAM? Also....how can we check the current GPU and RAM frequencies?

Dear d33,
But how then can you explain that I have been shown with 1,6 and 1.8Ghz using 4.2.2 wasser FW(ver.1.2.4) +Sam's overclocked kernes? In addition the stock 4.2.2 FW shows me 1.6Ghz too?

I love mine JD, runs beyond xmbc no issues and set up as TV on the go for me got travel pack Micro hdmi and sound pack all for under 140 bucks love it.
