Blacklist of locked Down Version´s of RK3188 CPU

[valzja]

nop... still strips...

[d33]

Higher voltage 1.5v kernel

[valzja]

ok

still no luck - strips on screen

[d33]

about this:
1.6 with fast RAM with desktop 1920x1080
strips on screen

1.7 with fast RAM with desktop 1280x720
strips on screen


i'm starting to think that this "T" junk is not for overclocking...
maybe should try 1.4ghz with RAM overclocking....

ok

[d33]

Any future people that test all I think we need to know is the fastest stable kernel and the leakage level from DMESG

Digger: 1.6 GHz with leakage level 6000
valzja: 1.6 GHz with leakage level 6000
mikele: 1.6 GHz with leakage level 4000
Norbert6: 1.7 GHz with leakage level 4000

[valzja]

Two additional kernels:

1.6 with fast RAM with desktop 1920x1080
1.7 with fast RAM with desktop 1280x720

NB. the kernels are not "720p" or "1080p" the resolution just describes the desktop. It is the HDMI settings that describe the frame rate and res set to the TV

d33, i found problem with your first build kernel 1.6ghz what i used - after ~15min of movie in XBMC my wifi drops in speed dramatically... only wifi turn off and turn on fix this... before starting to watch i have 11mbps, after 15mins of watching it drops to 0.6, but after off/on operation everything is back.

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

The 1.6 GHz build used reduced voltage to see it that made more/less stable.

I think we have an answer!

Present for Norbert > 1.7 GHz kernel with 720 DDR

Thanks a lot for your work, but I'm very sorry to say that this kernel cause some problems, after a short time the system freezes, again with a striped screen
I was able to run Antutu though, and it gave me around 400 points more than your original 1080p kernel.
Again, thanks for your efforts, really appreciate it.

[d33]

and what this means ?

Explained previously in the thread

[d33]

Two additional kernels:

1.6 with fast RAM with desktop 1920x1080
1.7 with fast RAM with desktop 1280x720

NB. the kernels are not "720p" or "1080p" the resolution just describes the desktop. It is the HDMI settings that describe the frame rate and res set to the TV

[valzja]

leakage level = 6000

and what this means ?

[d33]

this is my results of tests (my device - CX-919 v2.0)

i have made one more test:
i installed your previous build kernel, but only 1080p
Antutu freq - 1200 - 1600
Antutu score - 17307
dmesg here: https://dl.dropboxusercontent.com/u/...6cpu_1080p.txt

with the same build but 720p kernel i got Antutu score 18338, not a big deal, but UI runs smoother...

i hope this will be use-full info...

leakage level = 6000 @ 1.6 GHz

[d33]

@d33

My 1.6GHz DMESG is a big file you can find it here : http://uptobox.com/a3cdnwcd8dix

interested by 1.6GHz with faster ram !

Thanks

mikele's report

<4>[ 0.733400] DVFS MSG: aclk_gpu: dvfs_adjust_table_lmtvolt get leakage_level = 4000
<6>[ 0.734310] CPU is ROCKCHIP RK3188T
<4>[ 0.734349] cpufreq: delete arm freq(1800000)

So mikele can get max 1.6 stable with leakage level 4000

[valzja]

this is my results of tests (my device - CX-919 v2.0)

kernel_15_override_RAM
blank screen in boot or strips on screen

kernel_16_LV_override_RAM
blank screen in boot or strips on screen

kernel_17_overide_720_RAM
strips on screen

kernel_17_override RAM
Antutu freq - 1200 - 1700
tryed to run antutu - got strips on screen, and then after reboot only strips.

kernel_18_override_extreme_RAM
Anturu freq - 1200 - 1800
after few minutes of checking got strips on screen, but after reboot - blank screen after boot animation
but befor that i managed to get dmesg: https://dl.dropboxusercontent.com/u/...k18extrRAM.txt

kernel_18_override_RAM
strips on screen after boot animation

-----
what i done is - i only flashed kernels, originally i have your previous 720p kernel, who work fine...
can this be because i have installed originally 720p kernel and now flashing 1080p ? maybe i should try full re-flesh ?

can we do one more test ? d33, can you make kernel_17_overide_720_RAM but only 720p ?i have made one more test:
i installed your previous build kernel, but only 1080p
Antutu freq - 1200 - 1600
Antutu score - 17307
dmesg here: https://dl.dropboxusercontent.com/u/...6cpu_1080p.txt

with the same build but 720p kernel i got Antutu score 18338, not a big deal, but UI runs smoother...

i hope this will be use-full info...

Wow amazed at difference in leakage levels.
