Thanks for the reply. That makes sense :) Also, I believe _motley did increase the min pixclock a bit, as even his 416mhz gpu kernel went to 65fps and that is the only reason I switched to faux123 kernel as even at 520mhz it only ever gets to a max of 60fps. May I be cheeky an ask if the no pixclock could be lowered to 60fps? Also, what do you think about the cpuquite driver that faux123 is using, as it seems to have less slow downs, which I guess is because of the less latency of cores activation?
[Nexus 7 Original Development] clemsyn:
If _motley did increase the pixclock, then I'll change it to default on my next release. Now, who is up for a 2gh 725gpu? ;)
[Nexus 7 Original Development] sert00:
count me in clem!do you tried it already?:o

sure it can.i have yet to use it in last months to test new kernel and stuff.it's powrred off from months.

For the 800 timing,i think that ask with a kernel dev that works with t33 tegra3 Soc can help..like the ASUS Transformer Pad Infinity 700 (TF700T)..or at least,some of files from it.are there anything i link you that can help?like the boot.img or similar..?
[Nexus 7 Original Development] Metallice:
Morfic has the ram at 700mhz I believe. Just change the emc top slot from 667 to 800 in tegra 3 dvfs or just swap the emc freqs from soc speedo ID 2 with ID 1 which we use.
[Nexus 7 Original Development] luke05dee:
clemsyn, you said you managed to get the tegra 2 gpu over 400mhz, in the galaxy tab 10.1 forum there was trouble getting it over 400mhz and it just wouldn't seem to work. I don't suppose if you have a minute free you could pop over there and give us some tips please? Here is the page that we talked about overclocking over 400mhz: http://xdaforums.com/showthread.php?t=1833136&highlight=gpu&page=52

Thanks so much, sorry about this being off topic. :)
[Nexus 7 Original Development] clemsyn:
400, I got it at 600mhz ;) I'll take a look there later. I made a post there...I can't find his git though.
[Nexus 7 Original Development] Rafase282:
I'll give it a try.
[Nexus 7 Original Development] clark707:
I'd like to be a tester for this kernel :)
[Nexus 7 Original Development] leonbarroso:

I love see the thing burn ... heheheheheh

but there is an way to control GPU clock ? I Think my device likes more CPU OC than GPU OC
[Nexus 7 Original Development] clemsyn:
Test kernels of 2.0 ghz and GPU 725 released to willing beta testers ;)

1.8 ghz with 650 GPU updated and released ;) Need input. Thanks
[Nexus 7 Original Development] extremetempz:
ill test
[Nexus 7 Original Development] matus201:
For me the whole tablet froze with your 700 GPU kernel after playing NOVA 3 for about 2 minutes.. I love your work, but I think my tablet is not the chosen one to be able to run this :D
[Nexus 7 Original Development] t_007_v2:
Are you playing at 1.8ghz? If you are use 1.3 to 1.5max let the gpu do the work. There is not one game out that needs 1.8 yet but hopefully soon. Cheers

I've been testing the new 700 90fps one this afternoon. It's working great so far with no pink and no crashes. Been playing the bard's tale and some asphalt 7 high rez maps enabled on a7 while sitting on the beach this evening very very smooth on both. Will test it on TDKR a gameloft game that taxes the n7 pretty good.

Nice work clemsyn superb really.
[Nexus 7 Original Development] THADDIUS25:
I will also test for you
[Nexus 7 Original Development] genetic608:
I'd love to try it out. 1.8 700 worked well for me, med pixclock got a bit warm but no pixclock seems ok and I was able to run basemark es getting 25.77.

Of course count me in for the test ;)

I am running the 1.8 ghz with 650 GPU frequency and everything seems to be working great. I only run the cpu at 1.4ghz, and while playing games it doesn't seem to get that hot. Also, I am liking the no pixel clock increase. May I ask what 2d/3d bus's you overclocked and by how much out of interest please? I have attached a basemark e2 benchmark if your interested. What do you think about, maybe a 600mhz version of this please? (As call me a wimp:(, I don't feel that comfortable at as high as 650mhz, my personal limit is about 600mhz :D )Also, stably seems to be fine so far, thank you :)
[Nexus 7 Original Development] clemsyn:
Try the latest 650mhz gpu.
[Nexus 7 Original Development] dosenfisch:
I've tested the new 1.8/650 Kernel and it's faster compared to the old 1.8/650 but nearly as unstable as 1.8/700.

The CPU needs 1.125V instead of 1.1V at 1.5GHz.

GLBenchmark 2.5.1 and Nova 3 freezes every time.

Basemark ES 2.0 is running without problem and ~5% faster.

Can you make a 1.8/650 default pixclock build without increased pll_c and host1x?
[Nexus 7 Original Development] lasset:
Hi

Running 1.8 700GPU, works splendid. Like to be a tester for the new config.

Lasse T
[Nexus 7 Original Development] nexus7owner:
I'll be happy to test also I love the 1.8 so far plus doesn't seem to heat up
[Nexus 7 Original Development] dSlice:
I'm really digging the new kernel you have, 2 days uptime and still have half a battery left! Kudos!
[Nexus 7 Original Development] clemsyn:
Please try my latest 1.8ghz 650 GPU. It has emc voltage decreased to 1.10 mv to help battery life or wait for my extreme undervolted stock kernel for better battery life ;)
[Nexus 7 Original Development] clemsyn:
Thanks.. hoping I was in the beach too ;)
[Nexus 7 Original Development] Rafase282:
Should feedback be provided here or via PM for the 2,ghz with 725 gpu?

Also any tool in particular you want me to try?

I dont remember if it was here or motley's thread that people were talking about outdated benchmark tools
[Nexus 7 Original Development] t_007_v2:
Clemsyn you are like the savior of the n7. You have single handedly pushed this device where few thought it could go. These kernels are not just for testing there suitable for daily use. Been using the 1.8 650 since it's release rock solid and stable as anything can be. Imo makes gaming a joy on my n7. A well deserved donation is coming I promise (;

It was me... Be warned if you test it with quadrant or nenamark they will put your head on a Pike for display in the market Square.
[Nexus 7 Original Development] danielsf:
Been running the latest 650mhz gpu and 1.8ghz cpu build for a while now. I have been playing game after game and absolutely no instability also is it just me who thinks it is outputting a bit less heat that the previous 650mhz build? Not only that but I have two nexus 7's, one stock and the other with this kernel. Doing the same thing on both is interesting, as in scrolling on you tube or on the android market where there are a lot of things to render and cache quickly seems to be smoother and faster on your kernel even at the same cpu clock speed than the stock. This is my favorite build yet, thanks :)
[Nexus 7 Original Development] clemsyn:
PM would be great.

EXTREME Elite Battery Saving Kernel to be released in another seperate thread to avoid confusion.
[Nexus 7 Original Development] clemsyn:
It should ouput less heat due to decreased voltage on emc while in use.
[Nexus 7 Original Development] Rafase282:
The new 1.8ghzCPU and 650mhz GPU version has the link broken, cant download.
[Nexus 7 Original Development] nexus7owner:
I just tested the 2Ghz 725gpu and i guess my device can't handle it ... Now it won't turn on does anyone know what or how to fix this
[Nexus 7 Original Development] superbeak:
plug it in to ac power. Does the charge screen show up?
[Nexus 7 Original Development] leonbarroso:
700mhz or 725mhz is too much for my device

very unstable, freez system and auto reboot

I guess woud be better a gpu control, since we can control cpu already

I think my device would be fine with 650mhz gpu and 1.9ghz kernel, or even 2ghz

with no pix clock oc
[Nexus 7 Original Development] nexus7owner:
Yea I got it to boot idk of I wanna try that again :D
[Nexus 7 Original Development] darkchazz:
I don't know why but my cpu frequency resets to 1.3ghz I soon as I lock the device. I have to set the OC again every time I unlock the device :(

This also happens on other kernels.

Any fix ?
[Nexus 7 Original Development] simms22:
your rom is "broken" and doesnt have the powerHal fix. there are only a few cpu adjustment apps that include the fix(setcpu is not one of them). also, you could try installing/updating your busybox. stericsons busybox app can install/update it for you, its free in the market.
[Nexus 7 Original Development] darkchazz:
Thanks for the fast reply :)
[Nexus 7 Original Development] sert00:
flashing now the 2 ghz version.hope to have an elite chip,like i had on TF when i played with yours tegra2 kernel.let the show begin if my Soc don't refuse that freq.;)

EDIT ok...no problems with the 725gpu..but i think i have problems go over 1.9.when at 2 ghz it reboot fter a minute.i want to up a bit last 2 slot's freq voltage to see what happen..at least to have the time to do a fast bench..

EDIT 2 no luck also with a slightly overvolt of 25 mv on 1800\1900\2000 slots..if i choose 1800 min max and do a bench,no prob so far,the gpu works well at 725.Anyway it's the thing that i want,no problem playing with gpu,if the cpu can't reach 2 ghz,no problem,it's only a curioity thing,instaed the fact that my gpu works well at that freq. make me happy more than the cpu.i don't know well this chip,but in my gnex gpu oc is more important and significantly evident to see..

>EDIT 3 spoke too soon..now also on 1.5 cpu after a bench it reboots...what a pity then..

ehi clem,if you have time,can you compile 2 version like this but separate?i think that many people would need that..a 2 ghz 700 gpu or 650 and a 1.8 cpu and 725 gpu...in this mode,who have problem of cpu,can have the max gpu oc with same cpu clock that older kernel,and viceversa.thanks in advance if you would consider doing that.i have a question..what governor you reccomend in yours kernels and is there hotplug function in any of yours governors inside the zimage?curious to know waht governor play best with this tablet..

yesterday we speak about the clock of ddr3 in our device and tf pad (670 to 1600).i tried this 3ad,take a look at the post and at the pdf in the link,hope this help you figuring if the ours ddr3 channel can have 1600 freq...

[Nexus 7 Original Development] Rafase282:
Plug it to the computer with the usb cable and turn it on. It happened to mine while at work. I just demanded a usb cable from a coworker and turned my tablet back to life XD

Going to experiment with voltages. Maybe raise them and see if it works better?
[Nexus 7 Original Development] nexus7owner:
Yea for some devices they don't seem to be stable and 2ghz dont work I just plugged in and then it rebooted hopefully clemsyn can fix this issue and we all could run his 2ghz kernel...
[Nexus 7 Original Development] clemsyn:
Thanks to all the testers of 2ghz kernel. It seems like I would have to increase the vcore from 1.45 to the maximum of 1.5mv. This will disable the ability to go to bootloader from the ROM. Also that increase of vcore should help with the 725mhz GPU. I'll build one tomorrow, I'll apply the low pll_C voltage too. For now, homework with the kids ;)
[Nexus 7 Original Development] IRX120:
Yeah the 2ghz won't even let me get to the power menu before force rebooting, also when I try hand go to recovery via the boot loader it sits on the Google screen is this an issue kernel related
[Nexus 7 Original Development] sert00:
it's a common bug the fact of not go in cwm via fastboot menu.it works only if you are connected at pc.strange the fact that setting at 1.5 the vcore..it doesn't work anymore the reboot to bootloader option.but it's a thing that be fixed before or after clem?have a good time with kids and family!:D
[Nexus 7 Original Development] pinoyto:
Clemsyn

Please make a decrease emc voltage for the 700gpu version. Id like a cooler device too.
[Nexus 7 Original Development] M3drvr:
There no powerhal fix in this yet? Mine resets every time screen goes out still.
[Nexus 7 Original Development] demandarin:
try this.

since this is based off Motley kernel, why not just flash the pwerhal fix along with this kernel? I attached it to this post just in case you don't have it. I have a stockpile of tweaks n stuff like this. just use twrp and flash this as the 2nd zip. it'll flash clemsons first then powerhal fix. then you should be good to go.
[Nexus 7 Original Development] simms22:
that's a handy file to keep around and share, when I see people need it, and that's pretty often. thanks :)
[Nexus 7 Original Development] leonbarroso:
if any kernel works for you, post which ROM you are using
[Nexus 7 Original Development] eliteone:
Ok, now I'm torn..... the new 1.8 GHz kernel works awesome. Where the older 1.8 ones were never stable..... yet I could run the 700 MHz gpu kernel just fine while setting the CPU down to around 1.6 ghz . Yeesh ! What's a guy to do :) thanks for all your hard work, and putting out these great kernels. Are you're new kernels going to be based on your most recent release? Would love to see if I can get 1.8/700 working :)
[Nexus 7 Original Development] benkxda:
Usually I can control the CPU clock with several apps and limit it to about 1.6 GHz or so. How can I do this with the GPU?
[Nexus 7 Original Development] eliteone:
You can't..... Ther are 2 different kernels one at 650 GPU and one running at 700 GPU
[Nexus 7 Original Development] clemsyn:
Update:

Currently in contact with cpajuste and see if we can control GPU ;) Will wait news from him ;)

So far, the latest Elite kernel is the 1.8ghz 650 GPU. Would appreciate input re: battery life. THANKS.
[Nexus 7 Original Development] IRX120:
Why doesn't the 1.8 and 2ghz work on some devices and not others? My GPU aparantly cannot function over 650 as those kernels immediately freeze on boot.
[Nexus 7 Original Development] clemsyn:
Its because some devices have better batch of tegras than others. BTW.

Big Thanks to leonmbj for his donation.
[Nexus 7 Original Development] leonbarroso:
so, any chance to get 2GHz + 650MHz GPU ?

Thanks for the props Clemsyn, good work! I know some of the folks in my thread will appreciate the ability to open it up a bit and break out the ice packs. It will be interesting to see what types of benchmarks can be had. What do you have the pixel clock set at for this version?
[Nexus 7 Original Development] Rafase282:
I just did that. FPS got a max of 111

But the overall score was 7181
[Nexus 7 Original Development] boynamedstacy:
Damn bro. Sweet!

You heard correct :D As I mentioned a bit ago, the tegra 3 has a sort of heat protection that will throttle back speeds if she gets too hot. I'm no stranger to frozen bags of peas, that's for sure :p

Sent from my Glazed-over Nexus 7

What up Motley! Thanks to you we have a dope and stable base to use to help reach these scores. As always, thanks a million brother.
[Nexus 7 Original Development] demandarin:
Well I just peaked @ 69.7fps for nenamark2. I can't score well for nothing in quadrant. My scores staying horrible. In the 5500-5600 range. Even at 1.7ghz. I think I know what's happening but DONT know why.

I've noticed THST the device will eventually run at 1.7ghz for a few secs/mins. After THST, CPU spy shows it never hitting those speeds again. It stays at 1.3ghz. Even though I raised freq. To 1.7ghz. That's why my quadrant so low. I've tried different gov. And such. I can make it througgh quadrant but the scores suck. Its because my device seemed to have locked itself to 1.5ghz or lower..lol.

I remwber motley mentioning were can only increase the voltage so much. Any more than THST and kernel log will report errors trying to run increased voltage that's higher than Max threshhold. Causing decrease in performance.

Any insight into this? Ill try benching at 1.5 & 1.6ghz and see if quadrant gives me better numbers.
[Nexus 7 Original Development] Rafase282:
Okay so I tested this and I like it. About teh toolchain you used, is that the linaro one that mortley uses?

If not, it would be nice to have him make a new experimental build with your changes. :p

[Nexus 7 Original Development] clemsyn:
According to secret, if it hist the temp limit it throttles down to 912 (not 1.3) so this is weird. Make sure you don't increase the voltage higher than 1240 for 1.7ghz since the limit set is 1240. If you set it higher then it does not run at 1.7.

No, I used my old toolchain coz I'm too old to learn Linaro :)

But be careful!
[Nexus 7 Original Development] clemsyn:
The GPU speeds scales up and down (and the vcore scales with it) depending on the voltage of the CPU, so as the CPU speed goes up, in which the cpu voltage goes up accordingly with the CPU speed, the GPU goes up too ;)
[Nexus 7 Original Development] benkxda:
OK. Thx for hat. This is different to the PC and new to me and others.

So it would be good for "non play smartphones" to have a medium CPU and low GPU frequency (battery!). A "only play tablet" should have high CPU and GPU frequencies, which means clemsyn's kernel.

The results are showing a really fast device comparing to the stock version. But honestly, I guessed it would be faster in some tests. There are way better results to be found in the web.

What are your experiences with benchmarks?
[Nexus 7 Original Development] tucstwo:
Not complaining just saying, the latest kernel updates with the 700 MHz GPU, none of the run more than 2 seconds on my N7. I still have to run your old 1.8 650 kernel if I want to use my N7. AOKP build 4. I guess perhaps my device doesn't cooperate with gpu settings that high.
