Unfortunately, my unit passes the test mentioned in step 4 in that article (setting MobileDock Battery Saving Mode and seeing if a keypress wakes the tablet) so I don't think it has the defective chip. Also, this problem only started 2 or 3 months ago and I've had the tablet a year, so I'd have thought it unlikely to be a hardware issue.

Unless......the article does talk about running the latest keyboard firmware as well. Mine says DOCK-EC20N-207. How do I check if this is the latest, and how would I go about updating it?

[MENTION=1637582]MRCANNADY[/MENTION] Out of interest, what version is your keyboard firmware?
[Asus Transformer TF700] Deathman20:
Sounds like the issue was resolved in later models, in 2011... or I'm still brain dead and not thinking straight :)
[Asus Transformer TF700] flumpster:
207 is latest.
[Asus Transformer TF700] LetMeKnow:
I am running your 3.3.5. So far, everything seems to work great. I am able to lower the GPU voltage than the above and stable. I will report back with the temperature and the battery life in a few days, thanks.
[Asus Transformer TF700] berek9999:
In which case I guess I'm back to square one again.
[Asus Transformer TF700] flumpster:
Have you tested the exact same scenarios using stock kernel ?
[Asus Transformer TF700] MRCANNADY:
Sorry, I am at work and left my tablet at home. I will check when I get off of work later tonight.

That's a very interesting article, I kind of thought that it may have been a dock issue, I will definitely review this tonight and post my findings here.

Thanks guys

Just an FYI Hundsbuah, your kernel rocks man! My tab is smooth as silk, no lag, and every app opens as soon as I tap on them.

great job!
[Asus Transformer TF700] berek9999:
Yes, with same result. :(

I'm tempted to try going back to an older version of CROMI from well before this all started to see what happens.
[Asus Transformer TF700] tijsva:
Donations made! Keep up the good work! ;)
[Asus Transformer TF700] Hundsbuah:
how about using the old dock firmware? maybe sbdags can include the older dock firmware as an option to cromi installer. then people with an specific old chipset can select the older firmware to avoid the battery dock drain bug.

Is it possible to download the older dock firmware from anywhere so I can try it? I must admit I don't really know about this - never seen dock firmware as a download. How does it normally get updated?
[Asus Transformer TF700] tjy8tim:
I cannot save GPU frequencies like I can for CPU. it says "Error reading valid cpu values!" Anyone has this problem or know how to fix it? Thanks!
[Asus Transformer TF700] Hundsbuah:
what happens when you re-read the values in the gpu section?

Gesendet von meinem ASUS Transformer Pad TF700T mit Tapatalk 2
[Asus Transformer TF700] tjy8tim:
omg you are good. reading the GPU values first before saving it fixed it!
[Asus Transformer TF700] Hundsbuah:
have you played around with changing gpu voltages with the new gpu ov/uv interface?
[Asus Transformer TF700] tjy8tim:
actually no. I don't know how to access that interface. is it from the app directly? because I don't see it there lol
[Asus Transformer TF700] Hundsbuah:
no for now you have to do it with a terminal with superuser rights. i hope i find some time to include it in my app. it seems i have to change a few lines in my app source to always re-read the voltages. it is caused because the app has the "old" or outdated gpu voltages and not the new ones

/edit: do you have the new cromi 5.0? have you selected gpu uv -25mV?
[Asus Transformer TF700] LetMeKnow:
Hi Hundsbuah,

I have been using your latest kernel 3.3.5. since you released it. Your kernel is very fast and very stable so far on my device. I have not test the extfat and ntfs yet because I am busy lately.. I don't see any issue at all for my daily usage, not a complete test.. :)

The big value added for this release is the GPU UV option on your kernel. Now, users can optimize it to their preferences. With my set up, I can reduce the heat from 57C maximum for the 3.3.4 to 49C maximum for 3.3.5 on the performance mode. My performance mode setting are 1.8G UV CPU and 650M UV GPU. My testing was based on surf the internet, watch youtube, stream movies, and reply messages on xdadevelpors website. I am using the performance mode just for those purposes. I checked the temperature every 5 or 10 minutes with Trickster app for more than 2 hours period. BTW, I use my own UV tables for both GPU and CPU to my preferences.. :) These are my UV tables if you want to test them out..

### CPU Under Volt!

echo "1350 1300 1250 1200 1150 1040 970 950 920 920 840 810 810 750 710 630 630 510 510 390 390 270 270 270 200 200 200 200" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

### GPU Under Volt!

echo "1385 1335 1285 1205 1169 1131 1093 1046 989 932 885" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage_control

Thanks again Hundsbuab. Your kernel is super fast and super smooth and a great combination with Cromi X 5.0. I don't think any other combinations can beat this one.. ;) Of course, it is just my own opinion.. :)
[Asus Transformer TF700] Hundsbuah:
wow thanks for your feedback, i really appreciate it!
[Asus Transformer TF700] Eddie Hicks:
I have been using CROMi for quite some time now but I just installed this kernel for the first time. So far everything is fast and smooth with CRMOi-X 5. This is the best my Infinity has run yet and it over a year old. I have a couple of questions. I don't have the slightest idea what to change on the settings for the kernel. Like I said so far everything is running great so should I just keep everything at the default installation settings? I would like a good balance of power and battery life. Also in Hunds app under GPU section Performance mode is set to 200. Seems strange to me that performance mode would be set much lower than powersaver and balanced. Thanks
[Asus Transformer TF700] LetMeKnow:
If I understand you correctly, you mean 200MHz. You want it to be around 650MHz to optimize for speed but not to much heat generating.. :)

About the default setting,, if you are happy about it, you can leave as is. Otherwise, you can play around with it to your like..:) One thing you may want to try is set all four core frequencies the same which give you a smooth feeling under a heavy loads. ;)
[Asus Transformer TF700] Eddie Hicks:
Thanks for the reply. Yes I mean 200MHz. That's what it was set to. I changed it to 650MHz as you suggested. I guess I'll have to search around to find more information on the settings.
[Asus Transformer TF700] sbdags:
Hunds there is a bug with mtp / usb to a pc with 3.3.5. I've just tested 3.3.4 and it works fine but 3.3.5 won't connect over USB. I'll have a quick look in the ram disk to see anything obvious....
[Asus Transformer TF700] Hundsbuah:
/edit: found the problem, here is a new kernel, please report if it is working again:

Changes:

- lp oc to 760mhz with interactive tuning (you need the new data2sd patch if you are on data2sd to get the newest interactive changes)
- should increase batterylife without decreasing performance --> please report!
- new kernel source merge
- 51mhz and 102mhz back (fixed supspend index - please tell me if sods are still gone! - you cannot set 51mhz manually - the kernel enters the state itself)
- minor nvidia hotplug throttle changes
- fixed usb mtp bug

Download Kernel: 3.3.6

[Asus Transformer TF700] tijsva:
For some reason my tablet just reboots randomly while in idle mode. I can play games, browse or use it np, but sometimes the tablet just wont power on anymore, and the back of the tablet feels warm (while i havent used it even :confused: ). Sometimes the tablet drained all of the battery while it still should have enough juice (charged overnight, only 1 hour usage).

Things I have tried:

-Format data + factory reset

-Stock settings from 3.3.5 beta, so no undervolt, with 520mhz gpu, even in performance mode.

Cpu ran great with 3.3.1 (1100mv for 1.7ghz), so I doubt the cpu is the problem (since voltages are higher at stock).

Im currently using the stock kernel with cromi-x, but of course that is not what I want.

Any suggestions? :(
[Asus Transformer TF700] sbdags:
Will test it now mate :)

Yes that fixes it ;) Nice one!

BTW are you removing the two rndis modules now as you left the insmod statements in your init.d file ;)
[Asus Transformer TF700] _that:
Of course you can overclock the LP core, but what is it good for?

Look at the diagram on http://www.nvidia.com/content/PDF/tegra_white_papers/tegra-whitepaper-0911b.pdf page 5.

I assume that NVIDIA knows their processor well enough that they designed the maximum frequency of the LP core in the stock kernel to be at the crossover point of the 2 lines - what do you think?
[Asus Transformer TF700] duckredbeard:
Just flash 3.3.6 in recovery to fix the usb issue? Is there a kernel installer we should use?
[Asus Transformer TF700] Hundsbuah:
yes you are right - i didnt know that doc. ill remove the lp oc and try to uv the lp_core as long as it runs stable, now its running 475mhz at a stock voltage of 1150mV. Maybe its also stable at 1100mV or 1050mV. Ill check this today

no installer, just flash the zip file

[MENTION=1995570]tijsva[/MENTION]: can you try the new version 3.3.6. it has also the suspend index fix. maybe today or tomorrow a new version will be released with again a change in the suspend index due new lp_core knowledge :D
[Asus Transformer TF700] tiernan22:
This is some great work, Hund. I haven't gravitated toward this kernel in awhile because of the battery life. I OC'd to 1700 and it's silky right out if the box. The consumption is on par with anything else out there. I'd be hard pressed to move away from this one as my daily driver.
[Asus Transformer TF700] flumpster:
Good work as always mate.

Running smooth so far with no problems. :good:
[Asus Transformer TF700] LetMeKnow:
Hi Hundsbuah,

I have been testing your v3.3.7. IMO, I think that it is a drawback from v3.3.6 in term of performance. I loose about 600MHz on CPU speed and 200 points on I/O with the same setup on the performance mode.. :( Your kernel stands out comparing with others in term of performance, smooth, and responsive. My tablet is running very well with your kernel and fast, especially 3.3.6. I hope that you could keep the performance as a priority for your kernel....:good: In term of stability, I believe that your kernel is running very stable so far. Overall, I think your kernel is the best of all... Thanks for an amazing kernel that you have.. :) It is just my opinion....;)
[Asus Transformer TF700] Hundsbuah:
I assume you are talking about quadrant? That can be because the kernel only brings additional cores online when more threads are running then in the old versions. This means that quadrant doesn't run on all 4 cores. That's why you have a lower score.

Other question: the tablet does not feel slower right?

Don't trust too much in benchmark test. They don't represent the real world

Gesendet von meinem GT-I9100 mit Tapatalk 4
[Asus Transformer TF700] LetMeKnow:
Yes, I am using quadrant as a quick test in general. If you scroll the pages or surf the internet, you don't notice the differences much.

However, if you are running a few thing at the same times, you will see it better. I have four apps running on the start up. With 3.3.7, it takes about 4 seconds before they are ready for uses. With 3.3.6, it takes only one or two seconds the most. The best test is to install 4 or 5 big apps from the store and try to edit some files from your system. You will see lags or unresponses with 3.3.7. It is less lags with 3.3.6. Please let me know what is your test result is. Sometime, I am off with my test outcome.. :o
[Asus Transformer TF700] steveman29:
I have also noticed that 3.3.6 was more responsive than 3.3.7, maybe because of lp oc. Also I don't think that lp oc would affect battery life, because I didn't notice more battery drain with 3.3.6.
[Asus Transformer TF700] Hundsbuah:
I'll implement an interface to configure the hotplugging config in runtime. There u can configure how and when the kernel brings additional cores online

[Asus Transformer TF700] Hundsbuah:
in general i mean v3.3.7 with lp_core undervolt.

Ok here is the new kernel with tegra hotplugging configuration interface (1st part, maybe i add some more interfaces to control hotplugging) but here ist part1:

Interfaces:

cat /sys/kernel/rt_config/rt_config

This interface can output following (i.e): 4 8 12

in this case it means:

4 / 4 (cores) = 1 this means that the hotplugging driver will only brings another core online if there are more than 1 running thread.

8 / 4 (cores) = 2: the 3rd core will come online when more than 2 threads are running

12 / 4(cores) = 3: this means the 4th core comes online when more than 3 threads are running.

You can change the values with (i.e):

echo "8 12 16" > /sys/kernel/rt_config/rt_config

this means:

8 / 4 (cores) = 2 this means that the hotplugging driver will only brings another core online if there are more than 2 running thread.

12 / 4 (cores) = 3: the 3rd core will come online when more than 3 threads are running

16 / 4(cores) = 4: this means the 4th core comes online when more than 4 threads are running.

/edit: you can also use 11/4 i.e - this means 2,75 threads (because its calculated with average values)

/edit2: with echo "0 0 0" > /sys/kernel/rt_config/rt_config you disable hotplugging with runnable threads

3.3.8 so far is running excellent. Changed the values to rt_config file to 8 12 16, and got my best scores yet on both quadrant and Antutu to date. Tablet is smooth, speedy and running stabile.

Thanks Hunds!

Question, to make the settings stick can I just add that line of to your init.d file or any file in that folder? They don't seem to stick after a reboot.
[Asus Transformer TF700] LetMeKnow:
I confirm that the setting is sticked with the command added in one of the files in the init.d folder.. ;)

So far, everything seems to run great. I will report back tomorrow with some test...

[Asus Transformer TF700] Hundsbuah:
i corrected my explanation of the interface. there was a copy paste mistake (thx flumpster).

in general every app or task or service or background task has one or more threads. a thread can be running, suspended, dead, or sleeping (or waiting for an event). this hotplugging driver only takes care of running (active) threads. with this config you control how many threads can be managed by one core (the fist number you pass to the interface). if there are more active (running) threads in the system, the tegra hotplugging driver will bring up another core online. same procedure for the 3rd (2nd number) and 4th core (3rd number). i hope this helps you out :) if not just write it try to find nother explanation

[Asus Transformer TF700] LetMeKnow:
I ran with 4 8 12 last night and had 4 core setting at 1.6 cpu, 600 gpu on my balanced mode setting. It ran only about 20 minutes and I felt the temperature a little warmer. I did try 8 12 16 setup but I did not like it. So now I am running it with a disable 0 0 0. I think that I like this setting better comparing to the other two. So far everything is running fine without reboot or crash but it seems like something is not correct on my device. I can not confirm what it is. I hope that more people report back so we can push this kernel to the next level... :)
[Asus Transformer TF700] Hundsbuah:
hm ok then it was maybe the undervolting of the lp_core. when was the tab rebooting? when it was idling or if you have worked with it?

@ anybode else who is running 3.3.7 or 3.3.8: who had already a reboot and if yes when? in or near "idle" state or when working with the tab?

i mean "idle" when you were just reading something or anything else where the cpu can clock down and switch to lp_core (low power core)
[Asus Transformer TF700] LetMeKnow:
So far, I don't have a single reboot with 3.3.8. It is running just fine. The response time when you click to open an app or when you are reading something on the internet and want to to go to the next page. It seems a bit slow in reaction.. I don't have a hard prove for it and try to understand what is the cause of it on my tablet. I keep changing new kernels and mess around on the 5.0.1 rom. Maybe I need to do a total wipe on my device and test this new kernel version again.. :)
[Asus Transformer TF700] Hundsbuah:
you can also read about interactive governor and try to tune it with your own settings. you can tune interactive governor with setcpu i.e

[Asus Transformer TF700] schmeggy929:
Is that with rt_config setting still at "0 0 0"?

I have been running 1.8 for all cores and gpu at 650 in balanced mode since 3.3.2. I find performance mode seems to have more lag and scores in quadrant and antutu show lower in performance than "my balanced mode"
[Asus Transformer TF700] LetMeKnow:
No, I switched it to 4 8 12 and still running it at the moment... I believe that Hund kernel has a thermal throttle. If your temperature is exceeded a certain level, your speed will drop and the performance will reduce a lot. Maybe it is the case with your setup on the performance mode. With 1.8 for all core and 650 on the GPU on my performace mode, my score is about 7500+ average and max at 7800+ on quadrant. My antutu score is around 18500..
[Asus Transformer TF700] Hundsbuah:
its not only done be me. its also implemented by nvidia to protect your tablet. throttling begins at about 70°C

lp core oc

[MENTION=2170908]Hund[/MENTION]sbauh,

Is it possible that you can give the users an option to OC and UV on the lp core? It would be nice that we can play around with it.. :) Thanks..
[Asus Transformer TF700] _that:
According to the NVIDIA document I posted recently, the LP core uses more power than the G core at higher frequencies.
[Asus Transformer TF700] Hundsbuah:
that would be hard, because the lp_core uses the same voltage table as gpu and so on. In fact. when you uv the gpu (that interface exists) you also uv or ov the lp_core

correct thats why i went back to stock and use -100mV for 475MHz. Thx again _that!
