turn on force gpu rendering in the developer options.. :p

I had it off already :( What scheduler and governor were you using?

Sent from my KRAKD-out Nexus 7
[Nexus 7 Original Development] simms22:
you want it force gpu rendering on. i use ondemand/deadline sampling rate of 15000 and up threshold at 98%.
[Nexus 7 Original Development] boynamedstacy:
Oh whoops, I read that last post wrong :p I'll try again when I get home. You using STPro I imagine?

[Nexus 7 Original Development] Rafase282:
Thanks, currently I'm not playing any games, just google music, and pdf for my upcoming classes. So I will be doing some note taking hopefully.

HOwever, I want to be able to oc to 1.8 or even more if possible when needed. Specially since SPB shell seems to make things slower.
[Nexus 7 Original Development] boynamedstacy:
Sorry, System Tuner Pro. What are you using to adjust your sampling rate and threshold settings?

-UNLOCKED VZW GSIII
[Nexus 7 Original Development] simms22:
oh, i used setcpu to change it. but tkt to turn off fsync and adjust the cpu speed.voltages stayed default. i tried adjusting voltages with setcpu, but it wouldnt set my voltages. then i tried adjust voltages with tkt, but tkt would only go as high as 1300mV(which is way too low). so, the voltages remained untouched. i probably could have done better and a bit more stable lowering 19 and 2ghz to 1450mV-1500mV instead of 1550mV.

Awesome, thanks dudes. I'll look into getting a higher score after the weekend chores are done.

-UNLOCKED VZW GSIII
[Nexus 7 Original Development] Rafase282:
I have noticed that the fps and scores arent much better than with 1.7

Are people using cooling solutions to get better results?

I even left the case on mine. I know it generates more heat but I like to test with the settings and conditions in which I would normally use it.

With that say, my tablet can handle 1.8, could I get a like for 1.9 or/and 2.0?
[Nexus 7 Original Development] willis936:
With the (necessary) temp throttle you'll get better performance by placing it in front of an ac than overclocking further.

Also your 1.5 final has godly standby time and still performs excellently during gameplay. It never hits over 50C. It would be nice to see the GPU go back up to 650 and the CPU up to 1.6 since those numbers are likely still attainable at reasonable temps with your recent tweaks. Thanks so much for this kernel. It's awesome!
[Nexus 7 Original Development] rabidrotty:
All I have to say is simply amazing. I don't understand why Google doesn't hire you and alit of the talent here. Just freaking wow. I was holding off on the Nexus 7 for October. A birthday present for myself. But I guess I have to reward myself a bit early.
[Nexus 7 Original Development] foxorroxors:
Dunno if it was a cheroot download I didn't try again but with the 1.7/600 when I loaded into the is there were green loads of green dots around some of my wall paper and icons.... anyone else get this? I guess my gpu can't take 600mhz? 1.7/520 works like a charm though.

Anychane of a 580 gpu overclock? =D
[Nexus 7 Original Development] modstorm:
As you said, your GPU can't handle the higher clock speed and as such shows up artifacts (green dots you get). Some peole will get that and others won't not every GPU can handle high clocks well
[Nexus 7 Original Development] JohnCorleone:
Could not hang at 2.0+....is Simms upping voltages and testing in front of air conditioner like normal. 1.9 seems manageable. If I get the OK to raise voltages I will give it another go but had a heck of a time getting recovery back for some strange reason. Had to flash another kernel through Flash Image GUI app....ooh. irc ...be there in a bit

Sent from my Galaxy Nexus using Xparent SkyBlue Tapatalk 2
[Nexus 7 Original Development] simms22:
no, not upping voltages. they are EXTREMELY high as they are. i would have liked to lower them, but none of the apps i tried actually lowered them. and yes, i was in a well air conditioned room . 1.9 is very manageable, even almost stable. 2ghz has to be treated very delicately to get to run, let the device just sit there for a good 5-10 minutes before adjusting it to 2ghz, so whayever boot up process finish running. i watched my cpu %, when it went down to 0 is when i cranked it up.

Beastly kernel

So I'm running the stock rom with the 1.8Ghz/ 650 GPU kernel. Scoring 5200 in quadrant, 69.8 FPS in nenamark. Ran Nova 3 perfectly smooth. How are people hitting 8000 on quadrant?
[Nexus 7 Original Development] JohnCorleone:
OK I went nuts and cranked it straight to the max as soon as it booted. I am going to give it another go because 1.9 seemed good. Thanks for the tips. I will get the air conditioner fired up too..

[Nexus 7 Original Development] CharliesTheMan:
I had the same problem with booting to recover with the 2.0 kernel. It seemed that before recovery opened the screen flashed and rebooted to system, almost like recovery ramping up the CPU caused a reboot before recovery opened.

I could boot fine so I took advantage of the negative and copied storage the flashed stock and put my data back and then started over clean.

Flashing the kernel would have worked but I didn't try that GUI program and knew formatting clean wasn't a bad idea anyway, but your way was easier. Just wanted to let you know I had exactly the same problem.

[Nexus 7 Original Development] JohnCorleone:
Yup we had the exact same thing happen. Right when it was going to go to recovery, it low flickered "Google" and just booted back up. Meh I know its savable. I am not done

[Nexus 7 Original Development] simms22:
if anything, force reboot the device. then go into the bootloader, plug in via usb, and choose recovery. if it wont let you choose, unplug and force reboot again. then go into tbe bootloader, plug in, and try again :)
[Nexus 7 Original Development] demandarin:
Cleymson might want to have a deeper look into this. I had what you described happen twice. Days/week apart or so. The kernel was so extreme it crashed my device. Then I wouldn't get past boot up animation. First time I had to use toolkit and I restored a backup. I was unable to get into recvoery without toolkit. Then everything was good. Days/week later I try latest version at that time. Then same thing happens..lol. it crashed while I was benching. Then it kept on bootlooping. Unable to get I to recovery on the tablet itself. I had to use toolkit again. This time I used it to put tablet in recovery and then I just flashed motley kernel. Them device booted up fine. I think what happens is, when it crashes, temps go sky high. Then when it reboots, it keeps trying to bootup with extremely high temps. Therefore it'll either bootloop or stay on boot animation screen. Flashing anotjer kernel cleared it and brings temps back down to normal.

Like others said, not all devices can handle the same extreme gpu & CPU overclock. So be prepared to have to use toolkit or use recoverynif something goes bad. Comes with the territory with extreme testing. Some will handle it fine. Others will get stuck like me n others did..lol

TIP I LEARNED THE HARD WAY: don't bench this extreme kernel with volume all the way up. Or be careful in games at extreme speed. I crashed while playing nova3. Sound crashed also and made extremely loud noise that looped. It blew my speakers or now they sound all distorted and like crap..lmfao. just a f.y.I. so it doesn't happen to someone else. I think it was when I was testing the extreme undervolted version. So it doesn't even need to be at super high speed to crash n case issue. Just know what you getting into :)

this kernel not for the weak hearted or someone who doesn't know how to use other methods to get I to recovery if needed. ADVANCED users only.
[Nexus 7 Original Development] willis936:
The lower scores are not a result of a lower clock rate but of temperature throttling. If the hardware gets too hot it will crash, to prevent this the system will slow things down when it's nearing the point of instability. As any seasoned overclocker will tell you: if you want to go faster you must go cooler.
[Nexus 7 Original Development] droyd4life:
Thanks, been reading a lot here and seems like I need to change governors, get cooling and turn off fsync (whatever that is) to get better scores. Will turning off fsync actually give better real life performance? Also, I realized that the default browser in the glazed rom destroys chrome :confused: looks like were going to need water cooling in our phones and tablets soon LOL.
[Nexus 7 Original Development] simms22:
a few more benchmarks at 2ghz and a time in state of 1900/1900 and 2000/2000..

Can't wait until the rest of us can try out this 2ghz kernel. #excited

On another note , the 1.8ghz 650gpu kernel is running great maxed out
[Nexus 7 Original Development] boynamedstacy:
Been running 2.0GHz for two days now without reboot. That is until I floor it and run a couple bench tests. Still looking for a solid rom to help reach the illusive 8000's :D

Sent from my SCH-I535
[Nexus 7 Original Development] JohnCorleone:
The bench tests are what keep it running at max freq the whole time. Simms and I test a little differently. I set my min and max (say 51/1900) but I use on demand and deadline

like I do in my daily use which isn't a true stability test. Running it wide open (2000/2000 performance is the way to find out if it is truly "stable" for daily use. Also videos and games are another good way to push the device because they make it get warm and use lots of juice. The funny thing about the 1800 650 GPU was I completely forgot I had it set there. I was just using the thing and noticed higher battery drain with screen on so I checked. There may be some 1850 max CPU with like a 550 (/probably still too high) that people could get away with using. . I went crazy and bought an unlocked quad core S3, Evo LTE (2) and this so I am willing to push this the most because its the cheapest to replace. Trying to resist the unlocked quad core 1.5 all black One X I can get tomorrow. I am starting to get loopy from maintaining all of these devices...

Another thing to try if you're getting less than stellar scores is to turn on force GPU rendering in developer options.
[Nexus 7 Original Development] clemsyn:
:) Thanks for the link. I think they also need to give credit to _motley in the post in which this kernel is based. This would not have been possible without his kernel :)

BTW, will try to fine tune the 2.0ghz more and see what we can do but I believe we have hit the ceiling :)
[Nexus 7 Original Development] modstorm:
Sadly I couldn't get mine to run at 2GHz :( Highest i was able to go was 1.9GHz however I couldn't get quadrant to run :/ As soon as I max out 2GHz my Nexus shut's down. I also tried increasing the voltages (1.9 and 2GHz) by 50Mv with no difference. Hope one day I will be able to run 2GHz :)

[Nexus 7 Original Development] Tom Fagerland:
Is this kernel any good for someone who's more interested in battery than performance, and stability even more than that? If not, what should I look at instead?
[Nexus 7 Original Development] nory82688:
First impression of the 2ghz kernel is it flies. Seriously. I didn't run any benchmarks, because I wanted to see how it ran during everyday usage . Clocked @ 2ghz max and 51mhz min on interactive , it ran great through everything I threw at it , lol until I tried YouTube like an idiot haha it froze and rebooted (which Im not surprised it did, 2ghz is insanely high clock speed) . I remember someone earlier saying make sure your volume is set low because he blew his speaker from something (thank god I remembered that ). Also, the tablet isn't even getting hot like I thought it would clocked @ 2ghz, but maybe its because I haven't attempted the performance governor yet like everyone else.
[Nexus 7 Original Development] demandarin:
This kernel is for the opposite. Performance over battery life. St least Initially as I'm sure Clemson will tweak it for better battery at high speeds.

MOTLEY, Faux, or trinity kernels are the ones you want to run for best battery life. But pick the versions that have stock gpu speeds or only sligghtly higher. The super high clocked ones burn battery faster. You can also underclock for better battery life. Plenty of people running kernels at 1.1ghz and see no loss in performance and get great battery life.

---------- Post added at 04:29 PM ---------- Previous post was at 04:23 PM ----------

That was me with the speakers..lol. its smart to have volume low because if it crashes and sound crashes also with it, it might pump out sound Way too loud too long. It'll overstress the speaker/driver. To where it blows or sounds seriously distorted and have crackling sound to it.

The reason your temps are staying low is because you aren't running benchmarks. Those will spike up the temps fast. I wonder why YouTube made it crash though. If you have flash installed try you tube on browser and see if it does the same thing.

Was just about to mention that. Battery life is great! Got this today-
[Nexus 7 Original Development] nory82688:
Now that youve tweaked the voltage a bit, do you think it will be a bit more stable for everyday use at that voltage? Or is that specifically for benchmarking?

Also, if you don't mind me asking, what did you use to tweak voltages and have them stick?
[Nexus 7 Original Development] simms22:
well it does feel more stable. i was using it at 2000/2000, im sure that it would be much better for every day with the low end lowered. and i used the trinity kernel toolbox. morfic made a new one for me to test with this kernel because the voltages in clemsyns kernel are much higher than in trinity kernel and the tkt app didnt support such high voltages. now it does, and morfic pushed it to the market as an update.
[Nexus 7 Original Development] nory82688:
Ok, yeah just updated my trinity app ;) I'll try out your voltage ( I know it varys from device) and see what happens as far as stability. Thanks again bro

Edit: 1475v was too low for 2ghz for me, so I bumped it up to 1575v and so far so good. Havent had a reboot yet, and have actually been able to watch YouTube again lol

My settings are still 2ghz MAX, 51mhz MIN on Interactive Gov.

[Nexus 7 Original Development] clemsyn:
In the second post, I have the 1.5ghz version which is undervolted. It should be great for battery life, that is if your device can handle it ;)
[Nexus 7 Original Development] clemsyn:
;) Aint this fun :)
[Nexus 7 Original Development] clemsyn:
:) Yeh, somehow we are just trying to break that 2.0ghz speed but that 1.5 extreme undervolted should be great balance between battery life and performance.
[Nexus 7 Original Development] clemsyn:
Thats great ;) _motley is a big part of this project. Thanks.
[Nexus 7 Original Development] nory82688:
this message is to anyone that is running the 2ghz kernel. if anyone had trouble getting into recovery and finally got in, how did you do it? ive tried going through the regular power menu on the tablet, ive tried going through rom manager, ive tried going through the bootloader, and also tried adb reboot recovery. everything is a no go for me. should i re flash CWM? Should i some how push the new kernel through adb? any help would be awesome lol
[Nexus 7 Original Development] pinoyto:
I agree. Clemsyn's 1.5 kernel is GREAT in battery life. My nexus7 is maxed out at 1.8 (runs 1,9 but unstable) but I've been using his 1.5ghz undervolt version daily. It's just that it's mixed with all this overclocking stuff so I suggest a seperate post for the undervolted kernel, maybe?
[Nexus 7 Original Development] modstorm:
Connect the tablet to your pc (usb) and then try to reboot into recovery. It worked for me that way :)
[Nexus 7 Original Development] pinoyto:
Have you tried connecting it to computer USB and entering bootloader from there (Have to be completely powered off). I have told clemsyn about his issue too, but I think it might be the high voltages causing it. But that was how I did it, and also I used the original cable.

[Nexus 7 Original Development] Rafase282:
Where do I get this one?

Nvm found it.

Will try it out. I have my tablet set to dual core and make it go into single core when the screen is off and at max 1.3 unless I need extra power to save battery on the 1.8 version, I neger got the 1.9 or 2.0 to test.

[Nexus 7 Original Development] simms22:

[Nexus 7 Original Development] espionage724:
ouch. Did you do anything else like init.d tweaks or anything? Maybe try using performance instead of ondemand if you haven't already. Also what ROM are you using?
[Nexus 7 Original Development] simms22:
you didnt set your cpu speed to 1800 high/1800 low. if you let it scale, the device will decide to use a slower cpu speed. also, you need to go to the devices main settings, developer options, and enable for gpu tendering. AND you need to disable fsync and run the ext4 mount script.
[Nexus 7 Original Development] t_007_v2:
something else must be wrong interactive 1800\102 he should be seeing high 5000 scores without the io tweaks. 3d score is horrible very weird.

my interactive w cfq 1800 / 102 is 7400 avg.

---------- Post added at 10:55 AM ---------- Previous post was at 10:50 AM ----------

is the 45c in the top left the core temp? you must of had it sitting on ice for a 2000/2000 bench???? should be reading 60c+ in a normal environment. nice score
[Nexus 7 Original Development] simms22:
plus throw heat throttle on top. looking at the scores, either he let the cpu scale or it was heat throttle(or both), because those arent the scores of 1800mhz.

---------- Post added at 10:59 AM ---------- Previous post was at 10:56 AM ----------

45C is after it started cooling off. during benchmarking it went into the high 60C's. no ice, a well air conditioned room works well.
[Nexus 7 Original Development] Bunie89:
i set the minimum speed to 1800, max 1800, and used Performance Governor. got 3700. Still not right =/ even turned off FSync with Trinity Toolbox.

EDIT:

I just noticed it behaving weirdly!

if im scrolling up and down a page, it will scroll smooth for like 5 seconds, then scroll with dropped frames for 5 seconds, back and forth. is this normal?
[Nexus 7 Original Development] simms22:
then its the heat throttle biting you. find a source to cool the device down. anyways, performance always gives me lowered scores.
