[Asus Transformer TF700] lucius.zen:
Hello all,

After reading feedback I have done some more work. In the past three days I have tried over 25 different voltage tables, this is by far the best. I literally cant get it to run any better, even a slight change throws cpu behaviour off. This time around the scaling and cpu times are even more balanced than the last version. While the last table improved scaling overall the mid range frequencies were still underused. With the recent tweaks I have been able to encourage the cpu to utilize mid range freq more, even while in performance mode. While in performance mode I ran several benchmarks, did some very heavy browsing, typed up an essay in google drive, and watched 4 hrs of HD video as a test. I must say i really nailed it this time.

Even while using the tablet in performance mode the bulk of the processing time is spent at lower voltages and only moves to 1.85 when absolutely necessary. I made a graph of cpu times at diff frequencies and the distribution of times resembles a smooth reverse bell curve that starts at 425 and goes up to 1.85. With the original voltage table the distribution of cpu times had absolutely no pattern and primarily bounced between 425 and 1.85. All the mid and low ranged frequencies are now used at a much higher rate (for some reason 1.7Ghz is the only frequency that still isnt used - im assuming its bc the hispeed_boost is set to 1.85 Ghz). Aside from scaling performance, the temp stays in a better range. I also havent had a single random reboot or ANR, even after repeatedly running Antutu and browsing 10 tabs in theverge.com.

IF YOU ARE HAVING ISSUES WITH CRASHES..... DONT PANIC......AND DONT RANDOMLY CHANGE THE VOLTAGES. The scaling is bang on (i wish middle freq were used even more but I have reached a plateau in improvement) and changing any individual value in the table changes the way the cpu uses different frequencies. IF VOLTAGES ARE TOO LOW SCALE THE ENTIRE TABLE UP 25 VOLTS AT A TIME UNTIL IT IS STABLE. DO NOT SIMPLY CHANGE INDIVIDUAL FREQUENCIES AS THIS WILL CHANGE CPU BEHAVIOUR. You will probably need to do this bc these are absolutely the lowest voltages for each frequency that i can run on my tab, and my tab has a history of running well at low frequencies

I also added a new little trick. I dropped the 1Mhz frequency right down to 600 mV bc it is only used when the tab is asleep. If by chance your tablet starts getting warm simply shut the lid for 2 seconds, it will almost immediately drop the CPU temp 8-10 degrees. it used to drop about 5 degrees when i shut the lid. If your tab freezes when you close the lid then the voltage is too low, scale up 25-50 mV.

ALSO...ANDROID TUNER NOW SUPPORTS THE GPU OC INTERFACE. I emailed the developer of Android Tuner and he added support for our kernel a few days ago!!!!. GPU settings are also reapplied at every reboot so it doesnt need to be reset. Please use AT to set and apply voltage tweaks, I have used setcpu, nofrillscpucontrol, trickster MOD kernel settings, and system tuner. NONE OF THEM APPLY THE TABLE PROPERLY and dont allow you to keep track of changes in performance like AT does. Stick with it please, the dev also provides amazing support :).

Here is a link to download the voltage table, put it in the "voltages" directory in the "at" directory in your internal storage. You can now simply load the voltage table from the voltages control tab in android tuner.

For some reason the stock browser doesnt like opening google drive links, others browsers do work. I will upload a new link when i finish work i cant right now.

If you have any questions PM me. I have a lot of school work to do and cant be trolling around forums lol.

Happy tweaking,

Lucius
