If you have undervolted your Nexus 7 or any other tegra 3 based device please post the results here so I can throw them into a Excel sheet for development.
Using advanced mathematics and complex formulas I will make a undervolted kernel that's stable for everyone. For that, I need ideally 30 results or more. Less is ok but more or equal is better.

I also accept 1 frequency result. You don't have to undervolt everything. I favor the last known voltage that crashes as well if you can send this I am even more happy.

In order to use "advanced mathematics" and "complex formulas".. You might want to provide a format for "the results" you want people to provide.. Without a stream of formatted data to input your "complex formulas" and "advanced mathematics" is impossible..
"Advanced mathematics" and "complex formulas" sounds like you are doing an infomercial.
Pure waffle.

ha! good luck. considering some devices arent stable at all when undervolted just a tiny bit, and otbers are stable with a lot of undervolting, you have a tough road ahead of you.

I see you went with the more direct and honest approach. I tried being more subtle with my response.. :laugh: But yeah.. Marketing hype for a kernel.

Might as well be honest, set him on the right track early in his dev career rather than him rely on buzzwords and fud like some people do.
These are forums for android devices, not Apple devices, the reality distortion field doesn't work here, fancy marketing terms should be left at the door.

My Galaxy Nexus is proof of undervolting being unstable using software while being stable with manually programming the voltages. So I am going to give this a good shot anyway.
My Galaxy Nexus uses SmartReflex to undervolt.
Look at this table I made:
https://docs.google.com/spreadsheet/ccc?key=0AuqacKmGLKJ6dEdJZG5QTmNtQnoyYk0zbm5IanluMHc#gid=1
You see the core or gpu was already crashing at 974mV, which was the reason why I stopped undervolting using the thread. But don't give up, I tried again using SmartReflex because I felt I should be able to get lower. And now I am at 911mV but I did not try to get lower yet.
I plan on undervolting by actually programming it. I don't know how you guys undervolt for the Nexus 7, since I am fairly new with this device.

Using that I can calculate which voltage to take that will work for 90% of us or 99% of us or maybe 100% ?
For that I need some results. The more the better.
The only voltage settings that will work for 100% of people are stock voltages.
you will run into endless problems if you release an undervolted kernel because what works for 75% of people won't work for the rest.
If you adjust voltages to include more people the people that can handle the lower voltages aren't getting the full savings their device can handle. Which defeats the point of releasing an undervolted kernel to save battery.
Undervolting should be up to the individual, just release with stock voltages and make a guide showing people how to undervolt.

^^ Truth
I've done a bit of pc overclocking over the years and we'd always seek out the best steppings to find cpu batches that would give a better clock speed for less volts. What would work on one person's cpu wouldn't work on another sometimes even within the same stepping. (My current machine is getting long in the tooth but it's running a 33% OC below stock volts and stable as a rock.)
When the N7 cpu's are tested the stock voltage is the point where 100% of them will run without issue. Certainly there are many, maybe even most N7's that will run undervolted but until you try it you just won't know. Undervolting needs to be done on a case by case basis.
I uv by 100mv on every step on Franco kernel and I've never had a sod or reboot. Maybe you could release different versions like light, medium and heavy to cater to different users that have sets than can uv more or less. To address all these people naysaying I say just go for it, don't let these people dishearten you from what you want to do. I'm sure there will always be users who are willing to try
sorry to break the fun lol
Opened a thread with undervolting settings in different situation. For now i think its the lowest possible

That's exactly the same as what I have done. 100mV right across the board, and I have also never had a reboot or any other negative effect from doing it. Just a bit more battery life.
I too UV 100mv across the board. Never had an issue. And I OC up to 1.6ghz.

Same here, no issues with 100mv UV on stock speeds. What would happen if we went too low, would it fail to boot at all or is there some safety mechanism that would allow us to boot into boot loader?

When either OCing or UVing, you should ALWAYS test out the changes prior to saving them as a persistent boot state. This way, if you set something too high/low and it proves to be unstable, if you restart the device it will revert back to normal.
In the event that you OC/UV too much, yes, you would see signs of instability. In some cases it could show up as soon as you applied to change, in other cases it could take a while to notice. For example, some games or other high processing powered activities could FC/crash. Or your tablet might freeze or reboot. But again, as long as you didn't save your changes as a boot setting, it will be fine once it reboots.
In the event that you did save it, and the settings were unstable for your device, you could boot up into recovery and then manually erase them from taking effect. Recovery doesn't use those settings, as it's technically a different OS. But that can be complicated a process for some. So test test test save. Or don't save and just apply them manually.
Two other points:
Yes, most (all?) devices do have safeguards to protect itself against permanent hardware damage from OC/UVing. If it gets too hot, they will often shut down to protect themselves.
And just because one device can handle being OC'd or UV'd to a certain level doesn't mean they all can. Very minor differences in each component can impact one devices ability from another. The manufacturers only test to see if they can handle the published speeds/etc., but in many cases they can go higher if set to. In others, not so much.
Thanks for that phonic. Given the range of ROMs and kernel's available and the improvements already built in, under volting may not help a lot but every bit helps. Eg this screen on time is pretty good.Close to six hours screen on time with iirc 35% battery remaining.
Paranoid android with motley kernel. I don't over clock the nexus 7 as its fast enough. In fact I under clocked it to 1000 MHz max before and it was still fast but the screenshots are at stock volts and speeds.
it's actually plain simple. If everyone posts results. I can make a kernel with voltages that work for 75% of all people or maybe for 95% of all Nexus 7 owners.
It's called mathematics. But to do that I need as much results as possible.
Easy to do if you know what you are doing, right ?

So, i'm getting a really low 3D Mark score for a "gaming" device like this, i think that Nvidia do something wrong with the Tegra 3 GPU, i got it running at 650Mhz and i get like 3000 points... other devices on the same range get a lot better scores... what to do to get better 3D on our 4X?
Well this is my score...I'm not sure our much other devices get, but from the results our O4X is in the same range as the Note 2...so I guess that those results aren't that bad...
Btw I used the official CM10.1.0 rom with stock cm kernel...

Are you running anything else? I ran at stock speeds (no overclock anything) and got 4100-4200 on five straight runs. I have no idea what a normal score for the Tegra 3 is supposed to be.
I get same result. My kernel nothing touched from defaults.
I think it is ok all tegra 3 devices get similar scores one x+ gets about 3800.

for benchmarking, stock rom > aosp rom > cm based roms > other roms, from my experience. even when you bring custom kernels to the table, it's the same.
edit:
f.e., on quadrant, stock with custom kernels could go around 6100, aosp rom we have went to 5500, cm based went up to 4800, while others went up to 4500.

yeah, that might be the issue. unfortunately, tegra3 in our phone didn't quite live up to my expectations, which sux since even nexus7 has better performance than our phone. didn't try dead space either, so cant really tell. i did try vice city and nfs, they ran quite good on stock for me.

While it is indeed just a number, it does actually measure something. Unless my configuration is somehow exploiting it specifically to achieve those scores, you might wish to see why you underscore so much and fix it. The phones are identical after all, and no one is talking about fancy coolers or the like as exists in PCs.

I did some testing, and may have the answer for you. The vanilla iodak sets the CPU to 1.7GHz and the 3D and 2D GPU to 520MHz, all of which are maximum values, hence the very good 3DMark scores. If you use an app such as TegraOverclock and set those values you should get the same scores or at least very close to them. I did notice that any attempt to apply an overclock to the GPU was instantly rejected. If I tried to set it to 600MHz it was immediately set at... 300MHz, so as far as I can tell, 520 is the highest possible.

it puts to 300mhz because is the minimun, in 520mhz the minimun is 200...
Edit: flashed back V20C, getting 3570 stock, i will flash Iodak again.. and test... without donwloading tegra overclock...
Edit again, this is with iodak v6 stock settings it seems that thegra overclock app reduces the performance of our devices...
Stock kernel has its gpu running at 200mhz base, scaling up to 416. Custom kernels can increase that, which leads to higher scores. I got 4k by increasing gpu to 520mhz. I don't see how just having tegra oc installed could break anything
What this app is gonna do?
This will give you some boost that is really required to play games that are demanding on GPU front.
What this app require?
You need to be ROOTed and for that there is a really great app with one touch facility available! The link is http://forum.xda-developers.com/showthread.php?t=2387507
After you get ROOTed just install the Tegra Overclock OUYA EDITION app from attachment and click on OK for one click optimization.
You can also change the actual resolution to somewhat lower to again get a massive boost in GPU intensive games or shall I say those games that scale with GPU clocks very well. (I can confirm nearly 2X boost in RipTideGP2 with all settings maxed out when comparing with 1080p to 720p option provided in the app :laugh
Any kind of hazardous warning before use?
If anything goes wrong then you know where the power switch is! Close the console and cut the power and start again. We have not implemented the on Boot settings for safety reasons...
What about future updates?
I just wish that 4.2.2 gets for the OUYA and that will be a game changer for the console as that support full screen scaling on resolution changing vs screen compensation provided by current android 4.1 version....
NOTE: The app is fully free to use one click solution for OUYA owners and don't require you to get involve in any of cracking stuff Still the app does costs us in development and support front so any kind of donation will be greatly appreciated. If you are planning to buy any Tegra device in future then you can support us by purchasing the original Tegra Overclock app from the market that will in turn benefit you as well..
BTW don't forget to hit the thanks button
EDIT: Version 1.1 Change log
*Nothing new just made the interactive governor as a default rather than performance governor due to heating concern.
*Checked the code so that 2D GPU is set to 520 MHz too, in case it still reports half let me know..
EDIT: Version 1.2 Change Log
***Added requested LBCMT (LastBootCpuMaximumTemperature!) This shows the maximum temperature your device went during last boot.
***Added apply on boot (Works only when the USB device with at least a single file is detected to ensure you don't intentionally mess up anywhere )
The LBCMT will works as soon as you boot once after you open the app for the first time. Also note that YOU SHOULD NOT KILL THE APP manually by task killers or the reporting will be fake. BEWARE....
EDIT: Version 1.3 Change LOG
***Full screen stretched resolution support for CM11 Rom users. Use the special newly added resolution (will only work for CM users currently as no other 4.3 or 4.4 Roms available)
Fixes for temp not showing on custom kernel like EPRJ Kernel.
Thank you for being patient.

Just Press the OK button and wait a few seconds as the settings getting applied. After that Run your Emulator Games and you should notice a difference . Note that Resolution options also cuts the screen area so use them only if a game is unplayable!
is there no way to allow users to set advanced profiles so that they can configure a medium and max overclock setting?
i saw the temps on my core rise up pretty quickly just from fiddling with the UI, not sure if I want to subject this little guy to that much abuse with no really efficient cooling solution under the hood.

it's understandable for the lil guy to get hot quickly when you are overclocking the GPU+CPU, can't expected to run cool unless you put a better cooling fan into you console, i don't mid my ouya running a lil hot, well mines don't get hot enough cause my ouya got a acrylic custom shell with enough vents and airflow that keeps my console way cooler then the ouya stock/factory shell...
its obvious that it would run hotter if the clock speed is higher. no one is disputing that. i just don't see how not allowing the user to specify speed as much of the other CPU overclocking programs like SetCPU allow the user to do.
It's a needed feature IF it can be supported and implemented.
Excellent!
I'll give this a bash tonight and see what improvements there are!

Actually Temperatures are no problem for this chip as it can bear temperatures of 70 C with great ease as the manufacturer mentioned. Don't worry about that also let me know if they are above this temperature so that we can do something about that. If you ask me I am comfortable with 85C as that is what the throttle temperatures (Default mind you!). Just Relax and crush the games already

The custom CPU clock feature conflict the one click feature and not to mention lower clocks are not required as there is no trouble with the highest speed since the cooling is active and with sink. Just don't worry about the temps too much as everything is normal here and the purpose of console is to bear high temperatures with high load even with little heat management..
I have both the old app and the Ouya specific one and it looks to me that 2D GPU clock is set to 260MHz (1/2 of 3D clock). @Kingshoo, can you tell us what the "one click" settings are (governor, CPU clock, GPU, etc).
Much appreciate the work you've done.

Oh really If its working on Half then I will bump that to full to in next iteration
Settings are nothing but final settings in one click. Meaning Performance governor (Because this one has no polling overhead as opposed to interactive). GPU to 520Mhz, CPU clock to 1.7Ghz (1.6 on all 4 cores as set by OUYA). Ram at 800Mhz and also no throttling on Ram and GPU so that performance is reduced only due to H/W limitation or by bad coding practices and not due to some power saving logics

Cool...thanks! Looking forward to v2
BTW...for reference, I had my governor set to performance for a while and it drove the fan to run almost at all times. To the point I ended up shelling 20 bux to buy the Noctua quiet fan. Maybe others have better luck with the stock fan - but if noise is a concern, I found that the "Interactive" governor scales pretty fast with no visible impact on performance vs "Performance".
My 2 cents.
After reading several reviews about Noctua 40x10mm A-Series Blades with AAO Frame, SSO2 Bearing Premium Retail Cooling Fan NF-A4x10, I decided to buy it. I replaced the noisy fan of my OUYA, and the difference in sound is amazing. I had to check if the fan was actually running because barely hear it. Also, the temperature of my equipment dropped ~ 10°C, so overheating issues could be easily fixed, if you decided to overclock. I recommend this product without a doubt. Check on eBay or Amazon.
If you want to replace the fan, here's a guide how to do it. youtube . com /watch?v=rra0FwlHvBA
Well honestly I wasn't able to play games on OUYA but since you people are playing games what the temps of CPU are anyways after say an hour? I am asking this because I don't see a need for custom coolers as 50C or 70C it really don't make any difference to your hardware. Yes the fan noise may be concerning to many but I have cotton plugs in my ears to keep it silent (these really costs cents and not $$!). OK so newer version will have interactive on one click..
My stock fan is totally silent anyway

Cool...thanks! Looking forward to v2
BTW...for reference, I had my governor set to performance for a while and it drove the fan to run almost at all times. To the point I ended up shelling 20 bux to buy the Noctua quiet fan. Maybe others have better luck with the stock fan - but if noise is a concern, I found that the "Interactive" governor scales pretty fast with no visible impact on performance vs "Performance".
My 2 cents.

Greetings,
This driver is obtained from Qualcomm's 07 Aug 14 drivers for "Qualcomm Adreno 3xx GPU on Nexus 4, 5 & 7 devices running Google Android 4.4.4 KitKat".
All credits go to the folks at Qualcomm for making the developer version of these lib files available for us to play with.
This is for testing purposes only. Please don't flash without backing up first and then start screaming if something happens to your phone!
The package only contains files for Adreno 300 and 330. I cooked the packaged to be flashable on our SM-G900T or any SM-G900 with the Adreno 330 chipset.
I'm on a "XtreStoLite_G900T_ROM_v1.3_UVU1BNG3" ROM, which is a super clean/slim version of the stock rom. This is also Android 4.4.2, my AnTuTu benchmark results dropped from 37400 to 35800 after flashing this package.
I'm requesting someone with a KitKat 4.4.4 ROM to test this and report back their before and after benchmarks.
I appreciate your feedback,
Hmm, interesting.. I'm only on 4.4.2 or I would help out..
Turned out the 3D performance on antutu version 5 with this driver puts our phone one head and shoulder above everyone else!

And this means....... I'm sorry but I don't understand the purpose... Is this supposed to make Tw snappier?
Thanks in advance!
It is updating the video (graphics) drivers. It probably improves the touchWiz performance as well (don't have evidence to support this), but what i noticed was a huge performace increase in the 3D graphics score. This will make games run alot smooter and more efficiently.
To clarify, this file resembles how your Mac/PC has a video card with say NViDIA or ATi video cards and they have their own driver releases. Our phones graphic chipset is designed by Qualcomm and it gets its own drivers as well. Hope I answered your question, and didn't make it worse!

In order to get any real "TouchWiz/Nova/Apex/etc" performance increase from it you'd have to flash this, then venture into Developer's Options and enable Force GPU rendering and Disable Hardware Overlays. And even then our device is so performance driven that you likely would likely not even realize the difference other than giving the CPU a break for a few cycles and possibly seeing a battery life increase depending on whether the CPU or GPU pulls more juice. These drivers are largely made to increase the 3D performance of your device when gaming and while it wasn't meant for us I'm glad to see someone took the time to let us benefit from it.
I'm going to flash it on an NG4 (4.4.2) release and see how it holds up to GPU rendering no hardware overlays. I don't game so if you want an objective test on that someone will have to pick up my slack. I'll report back when I know if it truly impacts it.
Tried flashing the update and ran into a couple random fcs for a few apps. Nothing device-breaking or anything, but I also didn't notice any real difference in performance or framerate in games. But I do appreciate you posting this, I'm always up for trying a little experimentation on my device to find something new. Thanks man.

Don't worry, I didn't forget about you. It takes a few days to really put it through its paces. But here is what you want to know: It works in 4.4.2 Touchwiz (Alliance Rom B4 for me)
Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.
In the power draw category I need more time with BetterBatteryStats and I need to adjust some variables. I want to underclock the GPU to the point of perceivable lag (if that is possible) and then I want to adjust the governor with KTweaker and see if I can't get better battery life. I will simultaneously lower CPU speeds to keep my core temperatures down and keep the battery cool. If these things are successful and battery life is interchangeable between the two, I may run the GPU full time for rendering the ROM. Keep in mind though, only custom kernels allow this kind of tweaking. If you use a stock ROM you are stuck with CPU and GPU clock speeds where they are so battery will drain faster.
Give me about a week to test my theory on this and see if I can find an equilibrium for CPU and GPU temperature and speed. I'll post the profile I used with KTweaker when I have my results. Until then, if you want to help and find your own settings and post them here along with battery life that would be awesome.
Edit: For what it is worth, to test application launch speeds and UI fluidity with the GPU I completely turned off system animations, I set Nova Launcher Animations Speed to Faster than light and scroll speed to "Fast" (personal preference). I got the same, or better response time using the GPU to render the UI.

Thanks for the detailed response, can I flash this over a cm rom or only "touch wiz" and/or after I updated/flash this no Mauer what rom I flash will it stay. ..?
Thanks in advance! I'm still a bit confused...

I haven't tried it on CM yet, I'm about to flash the 09/04 build of CM11 by Albinoman with KT's kernel. But I won't flash these drivers prior to running the build 24 hours or so to make sure there aren't bugs that existed before flashing the files. So, if you've been running CM for awhile and want to test this build just nandroid, flash, and report any issues.

Ooo that sounds like a killer combo cm + kt kernel + adreno update = project slip n slide lol nah but I'm really curious of what results you might get [emoji4]
And once I flash this, can I go back or will it erase the update once I flash a different rom?
Thanks in advance!!

I'll keep you posted. I wasn't impressed overall with it's performance in Touchwiz on battery life with the CPU underclocked, so I am branching out to a more AOSP-like build. I'll keep you posted to what I find out.

This can't be right because right now I haven't flashed the driver update and look at My score
Now imagine that's without kt kernel just stock kernel, I'm on xtralite 3.5a t-mobile, so what if I flashed the kt kernel AAAAND the adreno update.... would my phone explode?!?!
I'm thinking twice now whether I should flash thisor not. ..
You have a good point. I think antutu v5 also rescaled their scoring system. Anyway, post your new score if you decided you want to give it a shot.

This maybe off topic, but does this works on other devices like Z2 or HTC M8 using the same GPU?
43718 before
43292 after
All I did was reboot into recovery, flash the ZIP and then run the test, same clock speed etc..

You guys make me sad. Benchmarks are not now, nor will they ever be, an acceptable means for telling you how capable your device is. Your scores in AnTuTu are about as capable of telling you your phone's speed as your ESN is at telling people who your phone belongs to. It is just arbitrary numbers that will fluctuate up and down based on the slightest inconsistencies.
Drivers, just like in Windows/Linux/Mac, are meant to optimize the performance of your hardware. That's it. This driver likely optimizes the GPU cycles to make it more efficient and lower heat output while performing better in games. You know why hardware review sites start out with benchmarks saying what it can do in a perfect world but still ends the review by telling you it gets 75 FPS in Borderlands 2? They do that because while synthetic tests are nice, what would be the point if our games don't play better? It is the same concept here.
I'm begging you, uninstall AnTuTu, re-install your favorite mobile game and just base performance off of whether it plays better or not.
Side Note: Drivers didn't appear to do anything in AOSP CM11 when I gave it a try. Sorry I am so late on reporting in, college takes up a lot of my time. Also, using the GPU to draw your applications does eat more battery whether you use these drivers or not. So there is no marked improvement from lowering CPU speed and using GPU only to render.

I figured since the OP stated he got less points in Antutu, I would go ahead and use the same app and test to compare...
F*ck me right?
Regardless, I don't notice anything different either, my stats are in the sig.
Hey I'm new to this undervolting thing. I believe I just undervolted by -25 globally using kernel auditor but my mV numbers in the boxes don't match the ones in this video(https://www.youtube.com/watch?v=T8THaPMp2ao). For example my bottom box 1040mV but the video's is 1010mV. Can someone please tell me what I did wrong and how to fix it?

If the app doesnt tell you, Wipe data on the app and reboot. Stock voltages are applied every reboot, until the app applies custom.
find out what you devices bin number is, then youll know what voltage chart your device should use.

Hey I've been experimenting on my kernel mostly based off another youtube video and i've been getting systemui closes after I reboot. I know it is either lmt launcher or kernel auditor that has been causing it. Do you think kernel auditor is the culprit?
it has something to do with lmt . I figured it out.

Undervolting isn't going to do much of anything for long term battery life. CPU's are very minimal battery users for most day-to-day operations, so your actual battery life gains are going to be minimal, <5%, if you notice anything at all.

I'd say even less than 5%, more along the lines of less than 1%. but its decent for lowering temps slightly as well. me, I dont undervolt at all, yet see from 5.5-6.5 hours screen on.
