Using the 666lp clock is fine as long as your device can handle it. You don't need to worry about it shortening the device's life span.

Is there any way to actually test to see if zram helps? Or do you just know?

From My Fusioned LG Spectrum Tapatalk Style
[Nexus 7 Android Development] Metallice:
Yes. Look at free ram. Compressing swap and moving it to your RAM just slows you down unless free RAM is your bottleneck... Which it most likely isn't.

right now im using 555mhz lp a26 and will be sticking to it until im feeling comfortable to switch to the latest one.

I am having a problem right now. I have been switching between motley and m-kernel and doing benchmark. I found that my 3d antutu score does not change with either rom. I tried overclocking the gpu with m-kernel to 516 and the 3d score stays the same. I lowered the gpu to 416 and got the same score around 2900. Same with quadrant, same framespeed with different clockspeed. Is it the same with everyone else or am i having an issue here? There was once my nexus 7 hang and restart by itself. While restarting the speaker output some weird noise but didnt seem to have caused anything.
[Nexus 7 Android Development] Metallice:
Antutu and quadrant 3d won't increase as they don't really tax the GPU much. Quadrant for example runs everything at the maximum of 60fps at 416 so an increase wont improve anything. You need to use a more stressful 3D test like basemark 2.0.

Restart with loud beep is usually from the GPU frequency being to high or voltage related.

[Nexus 7 Android Development] shongsa:
Thanks i will try basemark. Didnt know quadrant was limited to 60fps, with motley's kernel i could get up to 70fps. Is there a sort of framespeed delimiter in motley's kernel?

edit : i have tried basemark and basemark es 2.0 and there are different of framespeed with clockspeed. I tried with clock 416mhz and 520mhz and got 12.05 and 14.56 fps respectively with basemark es 2.0. With basemark i get 6-7fps more on 520mhz compared to 416mhz.
[Nexus 7 Android Development] Metallice:
Yes. It does nothing but inflate benchmarks limited by screen refresh rate and increase battery drain. No real performance gains as the screen can only display 60fps.

[Nexus 7 Android Development] knitler:
If I remember the CPU was bilt for 1.5GHz and runs that untill the OS loads, then it down clocks to 1.3 so that you can save some battery life/heat. so 1.4 is well in its limits.
[Nexus 7 Android Development] ximmox:
a28 is perfect so far, the slight scrolling lag I noticed especially in twicca with a26 and a27 is gone now.

Thanks Metallice, glad you have your/a N7 back!
[Nexus 7 Android Development] Metallice:
No it wasn't built for 1.5GHz. Running above 1.3GHz IS overclocking.

SOCs are built, tested, and binned based on multiple factors, CPU frequency stability being one.

The chips in our T30Ls are in our T30Ls because they were deemed not good enough to be placed in the T30s running at a max of 1.5GHz for whatever reason.

Now it is certainly possible that Nvidia uses some T30 quality chips to meet demand or whatnot, but the fact that many chips have difficulties running at 1.6GHz shows that 1.5GHz is definitely not their native frequency.

SIDENOTE: With Nvidia there is further sub-catagorization for each chip SKU (e.g T30L, T30, A33, etc) based on voltage tolerance. This is commonly known as your "variant". Every successive (increasing) integer variant runs each CPU frequency at 25mV less than the previous.

SIDENOTE2: However I would bet that all the LP cores are pretty much the same considering the higher ranked Tegra3's run the LP max at 620MHz, I can easily get mine up to 700, and everyone seems to have no problem running 666. Also, 475MHz to 700MHz is about a 50% overclock, a pretty big amount for practically all chips to be stable.

Sent from my Galaxy Nexus
[Nexus 7 Android Development] Metallice:
Cool. Thanks for the feedback. Don't known what twicca is, but if it seems that the LP core scaling down too aggressively was the cause of a large part of any stuttering during scrolling. The 2-3 second LP min capping to LP max seems to have solved this issue.

It definitely seems to be the case for for me on my new N7 using perfmon to monitor CPU frequencies. Even with a26, scrolling while using the LP core would drop down to 102 right after completing one swipe (meaning lag on successive swipes as it ramps back up to 666) or sometimes drop to 340 during the swipe for some odd reason (leading to lag in the middle of that swipe).

[Nexus 7 Android Development] Metallice:
oh and I'm glad to have a new one as well :D... Thanks in part (probably 50%! when you consider donations from before I broke mine as well) To all of you amazingly generous and supportive people.

Having 32Gb has probably increased my enjoyment of this device by at least 50% (well compared to a working 16GB)(obviously compared to a broken one my enjoyment as increased by 100% :D). 16Gb was an enormous PIA. Meaning Ill probably use it for longer and develop kernel for it for longer :D

[Nexus 7 Android Development] Awesoham:
Hey, that's nice to hear.

BTW what will the 700MHz OC accomplish?
[Nexus 7 Android Development] ximmox:
twicca is a very simple (but awesome) Twitter client.

Most likely so simple, that scrolling is the most taxing thing it does and the downscaling was nearly instant, exactly causing the stuttering you mentioned.
[Nexus 7 Android Development] xtcme:
Oh OK... That's kind of what I remember reading about the 1.5. Yea I'll keep it at 1.4. But from what I understand our units see the biggest improvement with GPU over clock. I wish I knew a proggy that showed me what GPU clocks are at with different kernels. Is there one?
[Nexus 7 Android Development] Metallice:
700MHz overlock of RAM? Possibly a performance boost. Need to test, but hard to tell since it is only about a 5% increase.

Hi, I'm using this on PA2.99, but usbotg doesnt seem to work, with trinity works normal?
[Nexus 7 Android Development] katestar:
Wow, this is cool, can't wait to try this out. Could the errors above 700mhz be due to invalid frequencies governed by the clock divider, so if you input a none supported value, you get errors such as green and red screen. I think we have the same memory as the t33, which is clocked at 800mhz, may I ask if you tried that freq? Also to test performance, might it be worth running some gpu benchmarks at high gpu clock speeds such as 600,666,700mhz to see if there is any improvement? I remember anandtech saying the only reason the gpu on the t33 at 520mhz beats ours overclocked to 520mhz is due to memory bandwidth.
[Nexus 7 Android Development] knitler:
Then why is it that when I first boot I see that in Trickester Mod that for a moment my CPU ran @ 1.5GHz? I don't have it clocked that high.
[Nexus 7 Android Development] Metallice:
Because that's the boot frequency of this kernel.

[Nexus 7 Android Development] necropuppy:
Finally got my 10 posts up.. Apparently my other username wouldn't let me post in general or in any forum at all. Anyway, I did it so that I could just post in this thread, because I love your kernel MetalIce. My device wouldn't suck without it, but it wouldn't be half as cool.

I'm using PA 2.99b9.5 w/ a28 and I've noticed a little lag with the xda HD app, but when I am scrolling at half speed it seems to stutter, if I do a quick swipe, it'll go go without any issues at all. I have my defaults to the ondemand as w/ stock settings (although I played with lowering sampling rate for better battery, which didn't make that much a difference overall except being less 'buttery') using ROW scheduling, which I dig above all the other ones.

Another thing I noticed while I've been typing this, since I haven't been on the forums, I haven't really had to type a whole heck of a lot, and I was just using the screen keyboard, hooking up my bluetooth (apple bluetooth keyboard I had lying around) I notice there is a small lag, when typing or definitely higher when backspacing. Anyone else experience this issue?
[Nexus 7 Android Development] ximmox:
Instead of altering the sampling rate, play around with lowering the up_threshold (I'm using 85 instead of 95 on a28) or try if upping the sampling_down_factor to 2 (or 3) instead of 1 is beneficial to your experience.
[Nexus 7 Android Development] necropuppy:
Ty, that helped with the bluetooth keyboard responsiveness (upping the sampling_down_factor to 3 and lowering the up_threshold 90), although I saw a marked increase when I upped the sampling rate as one would expect.

MetalIce, I was curious if there would be any way to incorporate the Westwood+ congestion algorithm in your kernel? I don't how that would compare to the current Westwood, but would it make difference? I use Veno at the moment, and I am quite happy with it, but honestly I couldn't discern any improvements from westwood to veno, just veno looked better on paper for handling wireless connections.

I am using a26 555mhz version. My tablet twice got hang and restarted by itself. While restarting the speaker output some kind of sound.
