I was using setcpu for a on-unlock profile. The setcpu simple interface for changing the three settings I'm really going to miss. Sys tune pro for the terminal, temp & cpu on times. I froze setcpu with titanium b for now.

dark meadow the pack is weird but the tegra 3 graphics are amazingly good and shows real possibilities for the future

With the way motley is going he will have us at 70 sooner than later. Good stuff man, 69 really?? Wow

I see motley got a 65.7 on the nena 2 bench and knocked me out of the 2nd spot. (;
[Nexus 7 Original Development] jombo2323:
Yeah, give it a shot. Grab a computer fan and a power supply and just blow a bleepload of air into it. Either that its possible that to compensate for my slight screen lifting that I got a better CPU/GPU

I wanna see someone over clocking the snot out of one of these while pouring liquid nitrogen onto the board to cool it.
[Nexus 7 Original Development] _motley:
Glad you got it sorted M3drvr:) Let me evaluate that for a second...blonde, M3, and OC'ed Nexus 7...not a bad combination in my book!

Any pics of the M3? Tuning cars (computer tuning) used to be a hobby of mine, but now I tune tablets instead. Just another set of tweaks and voltage tables, haha!

Most of these things won't do much for us. The swappiness and other associated swap settings were being played with on the Prime, but I don't think anybody quantified the results using a benchmark. A lot of young guys were just saying they thought it felt faster etc. Since i/o was slower on the prime, the idea was to stop using the internal disk as much as possible. When I looked at how much swap space was actually being used under normal usage, it wouldn't do most of us any good. I'm pretty sure laptop mode has to do with HD spin-up/spin-down timing and using a interim memory buffer to save power. Since we have SSD, that doesn't do anything for us. That said, don't be afraid to Google some of the stuff and see what it is all about. The worst that can happen is that you will learn more about the Linux kernel;) If you find something you think you want to try, Google the setting + Android and I'm sure someone has tried it before!

Great score!

Haha Charles, make sure you get a pic when you have something setup:p I'll provide a special OC version so we can see how high we can go :good:

Sorry! My cooling method was as follows....walk up to my sleeping 7, turn screen on, start benchmark while letting it lay on my wood desk;)
[Nexus 7 Original Development] simms22:
ive found that there is no cooling needed for the n7 and benchmarking(like on my galaxy nwxus who hates heat). in fact, i get the best benchnark scores when the n7 cpu is pretty warm, between 58-64C :)
[Nexus 7 Original Development] jombo2323:
Hey motley! if you make a overclocked version for me, such as 1.6 to 2.4ghz in 50mhz increments i will gladly go out and get some dry ice and overclock it when its sitting in a cooler full of it!

How does that sound?

i guess also overclock the gpu a little more too, but gpus never like to go over their stock max speed. the only reason the gpu can be overclocked in this is because its underclocked for heat and battery.

Testing will commence!

Also to the guy above me.....

Your statement defies all laws of computers. Why would it work better when its warm? IDK. why do processors even work, they shouldent. i guess anything can happen!
[Nexus 7 Original Development] M3drvr:
I said I feel like blonde Canadian girl. I'm anything but that as my avatar shows.

I had an M3 when I created my account. No more though. I live too far north now for it to be worth having one. But I miss it despite having a 335i now back home. Although I don't get to drive that either right now. Its tuned though. I got into car tuning from my old bf who had a skyline gtr and an M3 when I lived back in Taiwan. And got addicted and now I tune/modify everything I buy including my nexus 7 and gnexus.

Anyways ya I ended having to uninstall system tuner pro as well to fix my problem. Kept reverting to 1.5 even after adjusting bamf settings. Uninstalled system tuner n reinstalled and all is good again
[Nexus 7 Original Development] demandarin:
The pic in avatar is better than blonde girl ;)

All this tuning talk reminds me of wanting to buy handheld Diablosport Diablo trinity to tune my 08 Magnum. I love messing around with cars also. Part of custommagnums.com. xda has taken me away from there though. Tuning and Modding tablets much easier on pockets vs. Cars...lol.

Latest build has been running great so far Motley. Running it at 1.2ghz. Interactive gov. And deadline scheduler. -50mV Undervolt across the board. No issues at all. Plus temps love to stay on the lower end. Stable build, for me, for sure.
[Nexus 7 Original Development] Scott:
Your kernel is the DA BOMB!

I am hella impressed with it!

Thanks for the good work!

[Nexus 7 Original Development] _motley:
LOL, sorry about that. Well, minus the blonde part, my comment still stands since that is you in your avatar:o You sound exactly like me, always tuning everything I buy...lol.

Those are nice cars...would love to have a 335i or a 135i tuned. I was into Nissan 300zx and Mazdaspeeds, but they are far from being on par with those cars you mentioned. Nothing like a good dose of boost on your drive to work:good:

Glad you have your frequency issues sorted out with the app and rom.

LOL jombo...It could be fun if I had the time, but I was really just kidding around with Charles. I could see it if we had a couple tabs to burn and a nice little lab setup, but I wouldn't recommend it just to play around.

Agreed on that. I spent countless time and money tuning and working on cars. I rebuilt my own 300zx engine over one winter and my hands were always sore and cut up all the time LOL.

Glad to hear the latest build is going well. It has been flawless for me as well and I am getting great battery life. I think the fsync disabled really pushes it over the top as far as battery life and idle efficiency goes. I also leave wifi off when sleeping unplugged. I picked it up this morning after a full charge last night before I went to bed and it was still at 100% after 6hrs+ on battery/idle time. Right now I am at 1d 10h and still have 52% left after quite a bit of usage around the house today.

I have a Linaro kernel built for the prime with the ability to turn fsync off, but have only tested it on the JB builds thus far. I need to move back to ICS so I can see what type of performance it gives there. The JB ROMs don't seem to perform nearly as well as ICS did. I have not spent much time over there lately, but is that the general consensus with benchmarks on JB thus far?
[Nexus 7 Original Development] jombo2323:
i think it was far more sinister than that......

Imagine a cold dark night, motley at his desk wondering what to do.

He quickly whips up a kernel with the GPU running at 600mhz. He flashes his tablet and then throws it in the deep freezer after hours of hard cold he boots up the nexus and runs the benchmark as the atoms divide from the GPU being superclocked, he gets a score of 65.7 and then posts it (which I can't figure out how to do) and overwrites a poor civilian's score, effectively kicking them off of the top of the results chart.

Sorry I was bored and could not sleep.

I would like to do some extreme overclocking if you can find the time between optimizations. Just lemme know!

EDIT*

Facpalm you posted while I was typing on this dinky keyboard!

But really I would like to superclock!
[Nexus 7 Original Development] _motley:
Thanks, very much appreciated!

v1.1.1 is now tagged as stable since there are no known issues:good:
[Nexus 7 Original Development] espionage724:
Really? is there a source for this?

Edit: Nvm, searching lead me to a page that says 520Mhz :p
[Nexus 7 Original Development] BrandT90:
1.1.1 is running extremely cool. I was running the previous version and temps would range from 45C-50C idle on GPU OC to 484MHz with CPU underclocked and undervolted. Now I'm below 40C again. Such a great kernel _motley! Thank you!
[Nexus 7 Original Development] M3drvr:
Agreed, mine idles around the 37-38 mark. its nice. Reading PDF's is around 43-44. Rarely do i top 55. Definitely the coolest temperature wise. And i'm on the 520 version.
[Nexus 7 Original Development] airmaxx23:
What's everyone using to monitor the CPU temperature?
[Nexus 7 Original Development] M3drvr:
System tuner (pro), with notification packages in the notification bar updating by the second.
[Nexus 7 Original Development] GreyCelt:
System Tuner and/or Rom Toolbox Pro
[Nexus 7 Original Development] jaysmi32:
Trinity app has a nice cpu temp widget, works great for all modifications to the kernel too! ;)
[Nexus 7 Original Development] airmaxx23:
Thank you for all of the suggestions, I ended up buying System Tuner Pro.

I have the Trinity app but the widget info is only displayed in Celcius. :(
[Nexus 7 Original Development] M3drvr:
you could've used the free version of system tuner as well, but it only updates every 10 seconds i think. Still works decently. I like the faster updates though.
[Nexus 7 Original Development] jombo2323:
so motley, if everyone here is about 50degreesC, is it alright that i max at about 70 while running the 520gpu and 1.4ghz cpu after an hour of real racong 2?
[Nexus 7 Original Development] CharliesTheMan:
Yeap I would say it's fine even though that wasn't directed at Motley. Motley can give better instructions though about the thermal protection and if you could improve performance longterm by running less overclock and cooler settings. But if you're good with your performance like it is and not looking for more, I think that sounds about right, running it in those conditions for gaming is pushing the CPU and GPU constantly and those temps variances sound pretty on par to me from the little bit I know.
[Nexus 7 Original Development] mkiker2089:
Be careful with your temperatures. The Nexus doesn't report it's CPU temp in the standard way so I suspect those reporting 40s are probably looking at the battery temp. The only temp widget I've found that reports the CPU temp is Trinity's. If you are in doubt download a battery widget and see if the temps are the same. People further back in the thread were reporting problems getting the CPU temp to actually show but I can't recall the answer.
[Nexus 7 Original Development] t_007_v2:
Turn on a ceiling fan or something when gaming over clocked. Been playing heroes call that utilizes all four cores and it was crashing on 1.5ghz. Had to knock it down to 1.3 with a ceiling fan blowing then the game plays perfectly. All my other games are buttery at 1.5. Setcpu monitors the battery temp. Sys tuner pro monitors the core temp pretty darn well. Been gaming at around 140f or 60c with no issues.

Hit 65.7 fps today with WiFi off. 1.1.1 is a great gaming kernel!!!!! Louves IT!!!!!
[Nexus 7 Original Development] M3drvr:
I remember. We use system tuner.
[Nexus 7 Original Development] demandarin:
I use it also. System tuner properly display temps. I use tkt temp widget also and reports exact same temp as system tuner. I have battery temp widget(on my elixir widget panel) and its not the same thing.
[Nexus 7 Original Development] _motley:
Yep, System Tuner does works good for cpu temp, but when it heats up fast, it may be behind due to sampling time.

If you want to double check on the temp yourself, from a terminal or adb shell type:

cat /sys/kernel/debug/tegra_thermal/temp_tj

Units are in millicelsius, so just divide by 1000 to get Celsius (or just visualize the last 3 numbers as being to the right of a virtual decimal point)

The stock shutdown temp is 95C, so if you are running at 70C during heavy gaming sessions, that should be fine. If you like to be cooler, then downclock the CPU a bit or try a different GPU clock version. My dynamic edp governor is set at 68 and will work well under most normal circumstances except under repeated heavy bench-marking without and supplemental cooling.
[Nexus 7 Original Development] jombo2323:
Hey motley, im making a custom case for the nexus 7 with a fan and rechargeable battery. you should check it out, ill post a link to your kernel in the top section.

I spilled a beer on mine the other day. So I said "What the hell, how bout calling it liquid cooling."

I snapped a picture from my cell phone which you can buy on eBay for 49.99, just make sure you pay the $10.00 UPS charge and once I receive it, I'll email your picture. Subject line "Charlie's Drunken Chicken Cooling Blueprints."

I have a feeling motley is going to release a 1.6 GHz 600gpu butt kicker (; it's just to quite he's up to something.
[Nexus 7 Original Development] danielsf:
I think 600mhz is a little too much. I wouldn't mind a 550mhz ish one, which could be used without liquid cooling I hope. Although, I have to admit 600mhz does sound so cool, but it is whether it is usable or not I guess. :)

I am a noob to this. Can I just flash the kernel and leave it as is? And if I decide to OC, do I need to mess with the voltage or any other stuff? Thanks in advance!

Might want to try redownloading. I am running Jr4 and build 17 without issue. I flashed the kernel immediately after I flashed the ROM.
[Nexus 7 Original Development] luke05dee:
Thank you so much for this kernel :D The only thing I would love is someway to choose want gpu clock I have like a simple app. Wouldn't it be cool if I need battery I could under clock the gpu or if I wanted performance I could overclock to maybe 500mhz :D Sorry to bother you, it was just a thought :D Do you think it would be possible to ever get voltage control on the gpu, as I read somewhere that when a gpu is on high load, undervolting the gpu (if stable) can result in definite beneficial results (in producing less heat) as opposed to under volting the cpu which is somewhat controversial in it's effects. I don't like to overvolt much, so I will only overclock if I can get there with stock voltages. I am lucky, on my s3 I can OC all four cores to 1.6ghz using slightly less voltage than samung uses stock at 1.4ghz. Again sorry to bother you, it was just a thought :)

Modaco ROM v4

1. CWR = yes

2. Rooted = yes

3. Unlocked = yes

4. Busybox = yes

Just tried build17 its booting now. Hopefully no issues.

---------- Post added at 02:42 PM ---------- Previous post was at 02:31 PM ----------

Build 17 worked great. First boot = no overclocking with SetCPU (I bought the new version with some of my free $25 ;) )

Second boot = overclock available

To all who can't see the overclock:

Reboot again
[Nexus 7 Original Development] _motley:
Good to know about OTG, thanks. I hadn't tested this yet, but was wondering about it.

Hey, good to see you over here! I am using this ROM (r4) currently and it works great.

Hi, please make sure that you are using the latest recovery and that you do a full wipe before installing this ROM when coming from another ROM. There are quite a few running this ROM just fine. A few have reported in this thread that after they went back and wiped/re-installed fresh, it started working fine for them.

Yes, it would be helpful to know the following when folks report back:

kernel log (dmesg output)

ROM you are on (I don't yet know the details of all the ROMs and their ramdisk differences yet, but my guess is this is where the problems may lie)

8G or 16G tablet (don't think there are diffs, but I am not sure. Anybody with an 8G model running fine).

I am going to see if I can create an Anykernel install so we can slip the kernel without altering the ramdisk of the ROM. This could be the problem. If anybody running the EOS ROM knows how to repack the boot.img with my zImage, please give it a whirl and report back (there are not any kernel modules to pack). I may have time to do it tonight.

Hi, thanks for the feedback and suggestions. I'm sure we'll get there in due time. So many ideas and so little time...this thing called work keeps getting in the way LOL.
[Nexus 7 Original Development] giveen:
Must have not seen my next post ;)

motley, its working great. Thanks for your hard work. Wasn't able to OC till second boot.

---------- Post added at 03:02 PM ---------- Previous post was at 02:53 PM ----------

Couple interesting points:

1. Got best quadrant score at stock 1300mhz

2. Quadrant is detecting speed at 1600mhz, no matter what I speed I set in SetCPU

3. 1600mhz set using SetCPU caused bootloop

Kernel: Build 17

ROM: Modaco v4

Also, I had set it to "on demand" governor

1500mhz "interactive" caused a boot loop as well. Think I'll just stick to stock speed till your next build.

[Nexus 7 Original Development] danielsf:
I can't seem to undervolt, in set cpu it just won't set when I click apply, also when I try other apps it won't apply either. Any ideas please? I am on stock 4.1.1 and what are the voltages you are all running at please? Just to give everyone an Idea of how far this device can be undervolted :)
[Nexus 7 Original Development] Prey521:
Same here.....it allows me to change the values, but they never actually apply.
[Nexus 7 Original Development] antiochasylum:
What do you guys mean by bootloops?

Like once you set the speed, it reboots and wont boot up again? I hope you are UNticking "Set on boot".

Or does it freeze, reboot and go into bootloop then. Also when it boot loops, does it get back into the homescreen, or just displays the X over and over?

Because as long as you untick set on boot, if you overclock it, it should not bootloop. It will return to stock settings.
[Nexus 7 Original Development] giveen:
I do not do "set at boot" but it boots to the X and reboots. I can fix it by clearing cache in recovery.

Also after much testing of various speeds, governors, and voltages.......nothing beats stock speed, governor and voltage on this kernel under quadrant test

Also even-though I am set to 1.3ghz, it keeps jumping to 1.6. I'm going to have to go back to stock as I don't want to OC that high, but at least I know my tab is perfectly stable at 1.6ghz :)

[Nexus 7 Original Development] _motley:
Well, nothing being planned yet:laugh: Clemsyn is the proving grounds for higher clock speeds/voltages and he is using this kernel as as his base, so we can see how that goes. I did some experimenting back a few versions ago with raising the core voltage to 1250mV and 1300mV. This was the core voltage required to push the cpu voltages high enough to go to 1.7+/600. I released an alpha 1.7/520 version (with a 1250mV core if I recall correctly) and some folks were reporting random reboots, especially when screen was turned off which was kind of weird. That kernel didn't have fsync off capability, so the scores in Quadrant weren't as staggering as the ones from clemsyn's current expermental kernel. Hell, even this current kernel is scoring quite a bit higher now with fsync off.

Here is my current thinking on this... On the current version (v1.1.1) without trying real hard, @1.6/520 I have scored a 6938 on Quadrant, 65.7 on Nenamark 2.4, and nearing 13k on Antutu. Not bad at all for 1.6GHz. I can also run CF bench reliably and turn in a good score. Temps are good under heavy load and battery has been stellar with fsync off and wifi off when screen is off. After my last charge, I went about 7hrs at idle time before it dropped below 100% battery and was at 89% after 19hrs with moderate usage (browsing, some video etc.). As we test higher clock speeds (CPU and GPU), I think we need to look back at the current performance at 1.6/520 to see how much it really is yielding in comparison. We also need to make sure we are testing with tools that really show GPU performance increases properly (Nenamark 2.4 perhaps, but better yet Nenamark 2.5). The higher pixel clock rates that are now being used in testing, begin refreshing the same frame over and it isn't actually giving a real world FPS increase. At this point, it is just going to use more battery doing this extra work. Some benchmarks will show this as an increase, but Nenamark 2.5 should show the real world numbers so we can compare.

I really thought for sure when I got the tab that I would want to decrease dpi to 160-170 and run in full tablet mode, but I keep going back to stock hybrid mode and seem to like it better.
[Nexus 7 Original Development] demandarin:
I learned my lesson yesterday from running 1.7ghz & 600mix gpu. F'd up everything..LOL had to use toolkit to get into recovery & restore a backup. Nothing else would work.

IM back on latest stable 1.1.1 484mhz gpu. Set my cpu@ 1.3 ghz -25mv Uv across the board. Battery life really good.

@ motley since 520mhz gpu brings the heat, do you think a good middle ground might be wise? Like a 504mhz or something
