The low scores are due to low pixclock (700 pink fix has lower pixclock than 650 pink fix stable). Try using Basemark ES to really compare the differences.

The crash is most likely due to increase host1x speed to fix the dmesg errors. The host1x, if set to a different parent clock, will allow better overclocking of GPU but unfortunately gives out dmesg errors.

BTW, so far, good results from simms and pinoyto ;)
[Nexus 7 Original Development] simms22:
running really well here, the regular version not the pink fix. ill post sine graphical benchmark screenies shortly. did you change fsync location or remove the option to disable?

---------- Post added at 11:17 PM ---------- Previous post was at 11:14 PM ----------

nevermind, i found tbe fsync controls :p
[Nexus 7 Original Development] pinoyto:
Running great here too. Dmesg errors are gone. very smooth.
[Nexus 7 Original Development] simms22:
here's a few benchmark screenshots of the 700mhz GPU kernel, today's update, the regular one not the pink fix, of graphical benchmarks or benchmarks that include graphics tests. at 1800/1800mhz ondemand/deadline 15000 sampling rate, 98% up threshold with todays update of the rasbean jelly rom. most importantly its running very well and stable. today someone in the general section called me a trinity fanboy, when I didn't even mention trinity. so, from a trinity fanboy, well done clemsyn :)

[Nexus 7 Original Development] IRX120:
How'd you get such a high read rite score on quadrant standard? Mine is always super low
[Nexus 7 Original Development] simms22:
remount as ext4 script and turned off fsync(turn off fsync at your own risk)

remount as ext4 script in your terminal emulator(the trinity kernel toolbox app does it automatically for you)..

su(press enter)

mount -o remount,noauto_da_alloc /data /data(press enter)

This 1.8ghz 700gpu kernel is impressive. Everything seems faster. Been trying it out and its very stable. Great job clemsyn.
[Nexus 7 Original Development] katestar:
Just wondering if you had any plans to release stock pixel clock increases versions? Or maybe some kind of zip you can flash after you flash the kernel to choose to have stock pixel clock speeds?
[Nexus 7 Original Development] giveen:
Was in an hour long Skype call this morning, and now its overheating.

On this kernel, but no overclock going on. Device is burning hot, no screen, and won't power up or down.
[Nexus 7 Original Development] clemsyn:
Might have drained your battery, try charging it for 10 minutes then connect to computer USB and try to enter bootloader. LMK how it goes.

Thanks to pinoyto for first donation of this project :) Thanks man

1.8ghz cpu and 700mhz GPU has been pretty positive for most testers so I am releasing it in three types depending on pixclock increase. Max pixclock will limit to over 100 fps, mid pixclock will limit it to over 90 fps, no pixclock will limit it to 65 fps.

Also, if you like my work, dont hesitate to click on the "Donate to me" under my sig. Thanks.
[Nexus 7 Original Development] clemsyn:
Next up will be a 2ghz kernel with 700 gpu and then a battery saving kernel ;)
[Nexus 7 Original Development] clemsyn:
Yup, 3 versions of pixclocks released ;)
[Nexus 7 Original Development] CekMTL:
Hey Clemsyn, the for all your hard work!

I think the second and third link for the 1.8 700 point to the same file...right?

What are the chances of this causeing hardware failures.?
[Nexus 7 Original Development] simms22:
always a chance, but the probability is low.
[Nexus 7 Original Development] clemsyn:
Update:

I think we can finally have GPU control ;)
[Nexus 7 Original Development] Rafase282:
That is awesome!
[Nexus 7 Original Development] cammykool:
flashed ClemsynEliteNexus7GPU520.zip seems to run well at 370mhz min 1.5 max

not noticing much of a diffrence from the motley 1.1.1 kernel i had will keep this for higher OC thou!
[Nexus 7 Original Development] Pete7ate:
Thanks for the invaluable and enlightening contribution.
[Nexus 7 Original Development] duyquang27:
Awesome..... waiting 4 battery saving kernel and GPU control.... :D
[Nexus 7 Original Development] genetic608:
Trying out the 1.8 700 right now. The max pix clock gave me a bit of pink during animations, but the mid seems awesome so far.

I've been using the undervolted one at 475/1500 for a few days and this one is MUCH smoother at the same CPU

clock speeds, just a bit toastier ;)

Going to use it for now and I'll report back with battery life and some benchmarks in a few days

Thanx Clemsyn!
[Nexus 7 Original Development] pinoyto:
Clemsyn,

Thanks for the recognition, just a bit surprised that I was the first one to donate.

I inserted the file you sent me to /system/etc/init.d folder and changed permissions. Initially the fps in nenamark 2 went down as if the GPU was underclocked and I was getting 58 fps instead of 72. Unfortunately after a couple more runs, the fps went back up to 71 fps so it seems like the script is not holding.
[Nexus 7 Original Development] Rafase282:
I have problems with the 1.8 with 700 . Reboots when using it after a while. Are you interested on any logs at this point?
[Nexus 7 Original Development] leelaa:
Your device probably can't handle it.
[Nexus 7 Original Development] Rafase282:
Maybe, I ask because it was able to handle the previous 1.8 version fine.

I guess I just experiment and try to make it work or just fall back tot eh undervolted version I was using before.
[Nexus 7 Original Development] simms22:
mess with the voltages, they have changed between versions.
[Nexus 7 Original Development] leonbarroso:
I think the good way to go is the 2 ghz cpu with 700 mhz without pixclock overclock. in real life, there is no difference between 130 fps and 65fps. but there is a huge difference between 20 fps and 40 fps. and high cpu increases memory and I/o benchmarks too.
[Nexus 7 Original Development] t_007_v2:
The 700 gpu kernel gives better performance with a 3d score of 4100+ benched with quadrant Only problem pink artifacts are rampant with that kernel making it unusable unless you like the color pink. When I tested the 700pinkfix I got horrible scores worse than the 650gpu pink fix which is the one I have been using. The 700pinkfix gives me a 2600 3d score and nenamark 2 score of 64fps. The 650pinkfix gives me 3600 in quadrant and nenamark score around 70. Thx for letting me try it clymsen.

Cheers
[Nexus 7 Original Development] danielsf:
Quadrant is dated crap and doesn't really show you the full power of the gpu at all and nenamark 2 is almost as bad. If you want to see how good 700mhz is, use basemark es2 on the play store. Pixel clock increase will give you great results on old and very dated 3d benchmarks like quadrant, but in real life it is pretty useless and the pixel clock increase will show almost no difference in actual games. If you want to see how fast 700mhz is with pink fix, you use something like basemark es2 which will show you that the performance difference between 700mhz no pink fix and pink fix is the same. For me on 700mhz I get about 27fps on basemark es2 (https://play.google.com/store/apps/details?id=com.rightware.tdmm2v10jnifree&hl=en ) and on stock 416mhz I get about 15-16fps. Basically, never judge gpu performance using quadrant or nenamark, use something which will actually stress your gpu as in a benchmark that never gets close to 60fps to measure and compare performance. Pixel clock increase are next to useless for most people, unless you want bigger numbers in archaic benchmarks like quadrant. Hope that helps :)
[Nexus 7 Original Development] simms22:
vellamo had a really nice update yesterday, you should check it out.
[Nexus 7 Original Development] clemsyn:
Thanks for this. This tells us a good thing and a not so good.

The Good: GPU speed throttling works as per kernel and is regulated by the voltage supplied by the vcpu.

The Not so Good : It won't be as easy controlling the GPU as I though.

The script I sent was setting the max rate for pll_c which affects the GPU speed by a divider of 2 and the host1x with a divider of 4.

It seems like at boot, the GPU follows the max pll_c set by the script but as the voltage throttles up and down, the max pll_c rate is changed by the kernel thus resuming the high score in fps.

I'll consult with _motley about this ;)
[Nexus 7 Original Development] clemsyn:
Agreed ;)
[Nexus 7 Original Development] clemsyn:
Thanks for the great explanation. As GPU speed increases the chances of getting pink screen in high pixclock gets higher, thus a lower pixclock will get a lower score in outdated GPU benchmarks due to the limited fps but the latest GPU benchmarks would show the differences in GPU speeds because it will hardly get to the max fps limit.

Also, I noticed with nexus 7 with a default stock speed of 416mhz GPU you score about 15-16 fps. With the Gtablet which we at TeamDRH are working on at the moment, that is an old Tegra 2 device. I managed to score 19 fps with the GPU overclocked to 600 mhz ;) Although again, most Tegra 2 devices can't handle the 600mhz.
[Nexus 7 Original Development] jamesst20:
Wow AMAZING :eek: Why is my Launcher laggy when it open/close with these scores 0o
[Nexus 7 Original Development] simms22:
stock or customs launcher?
[Nexus 7 Original Development] jamesst20:
Both Stock and Apex are laggy ;/ Haven't tried others

Edit : Nova too..
[Nexus 7 Original Development] simms22:
go to the main phone settings, developer options, then enable force gpu rendering. reboot.
[Nexus 7 Original Development] jamesst20:
thanks, a bit better on the default launcher but no effects on others. Why?
[Nexus 7 Original Development] simms22:
the others might have their own performance settings? i dont know really, i use the stock launcher, and its butter smooth for me. you can try turning off animations in the developer options too, i have my animations disabled.
[Nexus 7 Original Development] jamesst20:
I'm stock rom + stock launcher and it is not as smooth as stock kernel or any other kernel :( But my benchmark is amazing and much better in all point then any other kernel. Nothing to understand :(
[Nexus 7 Original Development] simms22:
your enjoyability is much more important than any benchmark score
[Nexus 7 Original Development] jamesst20:
Yep :P I will probably not stick this kernel then ^^
[Nexus 7 Original Development] leonbarroso:
GL Benchmark 2.5 is freezing and restarting device (On Screen Egypt 2.1 test)

AKOP Nightly + Elite 1.8GHz/700MHz kernel

On Egypt 2.5 freezes at begin
[Nexus 7 Original Development] clemsyn:
which of the 3 kernels did you use re: pixclock?
[Nexus 7 Original Development] clemsyn:
As we get to higher speeds in Cpu/Gpu, more devices wont be able to handle the speed of the kernel. I suggest you use the 600 or 650 gpu since it has a lower host1x speed.
[Nexus 7 Original Development] jamesst20:
max pixclocl + the one you had sent me a while ago for the 2GHz kernel :P
[Nexus 7 Original Development] leonbarroso:
yeah

another benchmarks are freezing too

or it would be AKOP's fault ?
[Nexus 7 Original Development] IRX120:
My tablet reboots and freezes with the 700 kernel I couldn't even tap the screen without freezing
[Nexus 7 Original Development] CekMTL:
Running superb for 24 hours with 1.8 700 NO PIXCLOCK ... it seems that my Nexi is very picky about pixclock.

Even ran the old (self compiled from git) 2ghz and was running ok at that speed, although dmesg was a spectacle to watch... lots of clock errors and nasty things (but again, git is of an old version).

Thx Clemsyn, looking forward to your 2Ghz 700 NoPix. :)

Now off to continue tinkering with my Nexi, so i can watch DVB-T TV channels on it with a DVB stick I have here... almost got it working :)

BTW: at these speeds, my Nexi feels as fast in everything visual, as my ipad2... and THAT is a TESTAMENT! ;)
[Nexus 7 Original Development] Sultanxda:
I don't really trust Basemark ES 2.0 because on my Nexus 7 with the 700MHz GPU overclock I get 25.63 fps but on my year old HTC Sensation I get 33.05 fps. The Sensation is nowhere near as powerful as the Nexus 7 yet it scored 8 fps more.
[Nexus 7 Original Development] simms22:
the difference is also the screen resolution, the nexus 7 is pushing more pixels. besides, you cant really compare different devices with benchmarks, but you can compare the same devices.
[Nexus 7 Original Development] clemsyn:
I'll try to compile a 2ghz tonight, that is if my baby lets me. He has been so fuzzy the whole day.
[Nexus 7 Original Development] Rafase282:
Well no reboots or freezes on 1.8 with 700 gpu and mid pixclock. I never noticed the pink issue. Now I'm going to try disabling one or two cores to see if that was the cause of my problems before.

Edit: I just had to start nova 3 while on performance at 1.8 then it froze and reboot before i could play.

Time to try the no pixclock

Edit: same, cant play nova 3 on performance at 1.8

I doubt the leather cover is the trigger.
[Nexus 7 Original Development] clemsyn:
Try underclocking to 1.7 and see if it helps.
[Nexus 7 Original Development] clemsyn:
Try the 1.8 700 gpu no pixclock. See if it helps.
[Nexus 7 Original Development] leonbarroso:
have you run any benchmark ? (no quadrant)
[Nexus 7 Original Development] simms22:
i posted a bunch a few pages back, including quadrant too. runs stable for me at 1800/1800, without adjusting voltages.
[Nexus 7 Original Development] CekMTL:
Well, I'm not the kind of guy that believes anymore in benchmark, but in daily usage, and when it "feels" well, I know it's good...at least for me.

Now I did run nenamark2 and it gave me 64,2 without locking speed to 1.8 and today I ran vellamo and all was nice and smooth...so it's good enough for me (and kmsg is mainly quiet).

Enviado desde mi Nexus 7 usando Tapatalk 2
[Nexus 7 Original Development] simms22:
kmsg will usually be fairly quiet, do a dmesg. anyways, i checked out the dmesg, i didnt see anything jump out at me.
[Nexus 7 Original Development] Rafase282:
I did that while still using the nopixclock version and it was working well, then i played with activating and deactivating cores, everything fine, went back to the game, and it froze a little while afterwards, it didnt finished the intro.

I'm going to try uninstalling the app to control the cores and just test with the game to see any changes.
[Nexus 7 Original Development] nemesis93:
So I tryed the 700mhz GPU version with no pixclock overclock and it was buttery smooth? I had previously tryed the 650mhz pink fix and swiping home screens would seem a bit laggy.

I can't run the 700mhz GPU kernel cause my n7 can't handle it I get a bunch of reboots and upon boot on the Google splash I'd get an ugly white noise like line across the bottom and some scary noise coming out of my speaker with a pop to end it.

My question is how can I get the 650mhz kernel to run like the 700mhz did?
[Nexus 7 Original Development] CekMTL:
Well... dmesg takes it's info from /proc/kmsg ... I usually do a "cat /proc/kmsg" in an ssh terminal to get a continuous dump of what is happening.

Only way I found around this was to change the DPI to force it into tablet mode. Runs a lot smoother then. Doesn't happen on motley or stock kernel.
[Nexus 7 Original Development] darkchazz:
700mhz no pixel OC link is down (The following download is not available).

the undervolted kernel also.
[Nexus 7 Original Development] nexus7owner:
How do you get the 2MHz over clock I just wanna try it without a GPU over clock cause I tried the 1.8 with the GPU up and my device was hot if you know what I mean...
[Nexus 7 Original Development] masterg0g0:
Thanks clemsyn for the great kernel, a small appreciation from my end.

6XJ57441SK398830J

Guys please donate, and if possible. Even very small amounts can keep the enthusiasm up for all of us.

Once again thanks

Will try the 700 gpu on my N7
[Nexus 7 Original Development] simms22:
then your device will be even hotter with the 2ghz kernel
[Nexus 7 Original Development] clemsyn:
Thanks for the donation ;) All of a sudden, I started thinking about 800mhz GPU :)
[Nexus 7 Original Development] IRX120:
2GHz CPU

1GHz GPU

Could the device even function?

That be beast though.
[Nexus 7 Original Development] M3drvr:
None of the 700gpu downloads are working.... They download, but it's not a kernel. Downloads are only 270 bytes.
[Nexus 7 Original Development] masterg0g0:
Try to download via a different browser.
[Nexus 7 Original Development] M3drvr:
That worked. Thank you!
[Nexus 7 Original Development] CekMTL:
Hahaha ... well you know... the sky is the limit xD

Or more realistically, the different Nexus will be the limit, some of them will get to that point and some won't...the problem will be for sure the TDP... heat enemy number one, current draw enemy number two...but for sure most of us would give it a try ;)))

Can anyone provide mirrors please? I can't download from rapidshare.
[Nexus 7 Original Development] magooo:
i flashed this kernel over cm10 ... but when i choose 1.5ghz in the settings it always switches back to 1.3 after a while ... even after reboot it. how can i fix it? or is there another stable kernel for overclocking my n7? it seems like	thiskernel is discontinued
[Nexus 7 Original Development] Stephen.k.spear:
Discontinued? He put up a build like 2 days ago...
[Nexus 7 Original Development] luke05dee:
As the tegra 3 has poor memory handling, do you think it would be ever possible to overclock some buses, like overclocking the memory channel to have more bandwidth as I have read that it can have a positive effect on gpu performance http://www.anandtech.com/show/6036/asus-transformer-pad-infinity-tf700t-review/3
[Nexus 7 Original Development] tommykwan222:
Just have a test for the new kernel before.

When I set the clock speed to 1.8ghz and have the antutu test

Round that the score is quite low at 4000 only

Buy it said that run the test at 1800mhz
[Nexus 7 Original Development] B-Man2005:
im about to download the 650 Mhz gpu kernel

is it safe to play at that speed ?

does someone has experience with that ? dont want to overheat it :/
[Nexus 7 Original Development] magooo:
ok ... :D sorry ... i thought last reply was from august .... i don't know why .... i tryed to set 1.5ghz with setcpu now ... it seems to work now ;)

edit: just as i posted this i saw it switched back to 1.3 :(
[Nexus 7 Original Development] tommykwan222:
Yes

I am using this version now
[Nexus 7 Original Development] Rafase282:
Well I'm back to 1.8 and 700 maxpixclock no pink and no issues with stock voltages and using interactive. The issue seems to be overheating from using performance governor.
[Nexus 7 Original Development] t_007_v2:
Been using the pinkfix 650gpu since clymsen released it and it does a excellent job for gaming and is so very stable. Imo the 650 performs better than the 700 from testing nova3, horn, MC3 all the top titles on my n7. there is no need to over clock the cpu past 1.5 for any of the current games out right now it's just overkill. I just bought & downloaded the bard's tale 3.5g tegra optimized version i'm running at 1.4 with the 650 gpu game play is very smooth. If your n7 is in a case or protector heat could build up pretty quickly and lag could happen. The ceiling fan in my room keeps my n7 cool and running like a champ threw hr's of gaming. Game on (: !!

Cheers
[Nexus 7 Original Development] pinoyto:
Clemsyn,

I agree with this, can you try OC the memory to at least 800 and see how it does. Also tried your 800mhz GPU with no host1x and IT WORKS!!!! I got 28.25 fps on Basemark Taiji but with host1x errors on dmesg. If you move the host1x to the right place, then I can't boot at 800, I can only boot at 750 but hangs on 3d tests...725 mhz works with host1x in the right place...I get 27.08 fps with Basemark Taiji.

IMO, I think stick to 700 mhz GPU, its very smooth for me and increase the voltage a tad bit for more users to be able to run it.

About the pixclock, Just release a no pixclock since it gives us false benchmarks in old benchmarks by giving us over 100 fps but I think uses more battery.
[Nexus 7 Original Development] eugenechiuu:
Hi there, just got my nexus 7 few days ago and been using PA 2.13 and motley kernel.. Was wondering how's the battery drain for Clemsyn's kernel as a compensation for the performance?
[Nexus 7 Original Development] clemsyn:
In my second post, I have the balanced battery/performance kernel thatyoumight wantto try :)
[Nexus 7 Original Development] clemsyn:
Thanks for info, I'll look intothis. Also, in my1.8 ghz 700gpu, I noticed an error in on of my clocks. Will fix it soon ;)
[Nexus 7 Original Development] darkchazz:

The undervolted kernel please
[Nexus 7 Original Development] sert00:
good to see clemsyn develop on nexus 7!remember when i use yours fast kernels on my TF.:laugh:

being a possesor of N7 from 2 days,i read a lot of 3ad but i don't see what exactly the word "pixclock" refer to..can anyone enlighten me?i'm running the med version,no prob so far,all is absolutely smooth.played already few tegra3 games with no lag at all.

What luke05dee post few posts ago,is very interesting..yesyerady,when i read the specifics of tegra3 Soc,i wonder same things,also if we have the minoe powered tegra3 Soc,we have ddr3 ram and with a good gpu\cpu overclock plus a little oc to ram bus,from 667 to 800,we can achieve same exact performance\specifications like tegra3 t33 version..it could be a very good thing!or there are hardware differences also between 3 socket (t30,T30l,T33)of tegra3?

isn't the undervolted kernel version on rapidshare but also in attachment in bottom of second post...?
[Nexus 7 Original Development] eugenechiuu:
Thanks! Will give it a go!
[Nexus 7 Original Development] darkchazz:
Yikes! Thanks for that. didn't see it XD
[Nexus 7 Original Development] magooo:
I cannot use this kernel ... :( does anybody use this kernel with cm10?
[Nexus 7 Original Development] katestar:
clemsyn I believe a little while ago you were talking about looking into dynamic GPU clock speed control through some kind of interface, may I ask how that is going please? As it would be great to be able to have 600mhz with no pixclock.

Also, on the no pixclock 700mhz kernel it says it should be limited to 65fps, I am sure the stock pixclock is supposed to limit it to 60fps, so does it still have a mild pixclock increase?
[Nexus 7 Original Development] clemsyn:
The GPU speed wasn't that easy to control as I thought. Pinoyto tested a script I made that was suppose to lock the GPU speed to 400mhz. It works initially but subsequent tests showed it did not hold. The kernel controls the speed of the GPU by the vdd_cpu voltage. So as the VDD_CPU voltage goes up, the GPU goes up. I can make a kernel which would lock to a certain GPU speed but that would be a lot of work. The best would be for some app developer to make an app to control it so it can be controlled on the fly. I can give him the specifics on how it is controlled. The app should work on every tegra device out there (that is if it could be done).

re; pixclock, I used _motley's default speed of pixclock. Unless he changed it ;)
[Nexus 7 Original Development] clemsyn:
I've been looking at the kernel timings more closely and the memory speed we have is only up to 667 speed. If anyone can link to me timings for an 800 speed memory, that would be great.

BTW, that TF101 still has plently of life. Unfortunately, I no longer own the device, but as with my experience with GTAB, it can be clocked higher for better speeds in GPU department.
