Edit: for what it is worth, note that the lowest slot of GPU voltage is hardcoded at 950 mV (I got that from Trickster Mod support)

Hummm, is to high the lowest but ok, thank you.

You know the all lowest voltages i can set for proc, ddr...?

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

Here are my settings. It's modest but at least the GPU/LP/RAM never have 1200 mV.

I tried to lower the lowest slot for the lp core and RAM, but it always crashed.

Have you applied these crazy settings ... and what about the lp core ? Without this info we can t have a complete picture.

If you apply these settings quit and reopen trickster the lowest slot of GPU should be at 950 again.

[Nexus 7 Android Development] Metallice:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

Also your gpu is definitely not running at those voltages. There is no point setting anything below 950 as that is the lowest voltage for core components not part of the under volt tables.

So the core will always run at the very least 950mV.

Edit: and it is not strange. It works exactly as it should. Its just not simple since there is only one voltage rail.

I find the volume to be very soft especially so when i use my nexus on the tube and there's alot of ambient noise. It sees to be 50% softer than my note 2. I know that the audio chip on the nexus is crap as compared to the note 2 but is there some way to boost the volume?
[Nexus 7 Android Development] R3dbeaver:
stock ROM here. SG: DZ works just fine at High (thats the detected default) between a32 and a35. GPU @520 (tried 600 and 666, couldnt tell the difference)

heck i even disabled 2 cores and still works just fine.

lag probably comes from the server... but just curious, what benchmark did you use?
[Nexus 7 Android Development] Metallice:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

Speaker or headphones?

Yes it seems possible based on earlier changes to the audio codec. Don't really want blow my speakers or whatnot testing though.
[Nexus 7 Android Development] bervin:
headphones, the speakers are soft as well but like you said i don''t wanna blow them too. I would just really like to see the headphones volume being boosted. Stuff like scoobydoo sound or voodoo can't be applied onto the nexus 7 can it?

what i'm asking for is something substantial that will be applied to everything because it is applied at a kernel level not some EQ settings which is just applied to music apps. If something like Voodoo can be done then even youtube will have a audio boost.

Also i've noticed that no kernel dev for nexus 7 has tried to apply something like that as of yet, Metal has done alot in terms of perfomance and battery consumption. Maybe implementing some new features like this will pique his interest and of course i will gladly benefit:fingers-crossed:

I've got a 17" Samsung Chronos I7 I love it. I haven't used a mac since 1993ish. Just can't see myself feeding the machine. I like your kernel man keep up the nice work. You got everything I want including USB DAC. Is 16bit 48000 all we can get with a USB DAC? I'm just a user I don't know much about the nitty gritty stuff. I'd like to be able to output 24bit 96000 to a USB DAC is this a pipe dream? Thanks.
[Nexus 7 Android Development] Metallice:
Oh yeah the Samsung series 7 notebooks are pretty nice. The upcoming 2013 ones especially. Unfortunately no 2880x1800 resolution though. Honestly the series 7 would have been my choice. Still out of my price range though :P

I don't know much about USB DACs. I've always wanted to get one. Not sure if my ATH-M50sLE's are even good enough to bother. Have you tried 24/96k and it doesn't work? All I have done is enabled support for USB DACs in the kernel config. If it doesn't work it may mean that the linux kernel itself doesn't support it.
[Nexus 7 Android Development] Azurael:
Nothing wrong with Apple hardware. That, or a thinkpad are about the only things that will survive my abuse for more than a few months. I even quite like OS X, although I've got Gentoo on mine at the mo. The company sucks though, and I won't buy anything else from them on principal! Still, can't complain for free :)

Looking forward to A36, the battery life on A35 is epic :D

I dunno about bothering with a USB DAC on the N7 though... Aside from the annoying noise the CPU scaling causes, I actually think the audio quality on the N7 is pretty good. At least it is a lot better than my HOX or N4 with my IEMs.

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

Just wondering, what is the reason for raising the minimum freq default to 204?

ETA: and despite my avatar I've always had Macs. What dont you like about OS X? I'm curious not antagonistic.
[Nexus 7 Android Development] Metallice:
It's pretty much a requirement with the decrease in sampling rate, which itself is used to offset the increased up threshold. Just testing things out.

I hate the aqua theme for one. The brushed metal look is ugly in my opinion. I miss aero snap, although cinch works okay. The dashboard is 100% worthless for me. The os x dock used to be superior to to windows taskbar, but now I find the Windows 7 superbar with aero peek to be much better. Finder is just bad and annoying in my opinion, although I kind of fixed that with an addon app. While the trackpad experience is fantastic, using a mouse on OSX is awful. The mouse is slow, the acceleration curve is GIGANTIC and just feels very wrong, but again I fixed that with smoothmouse. Oh and I find launchpad to be another pointless feature. Also app support is terrible. I'm constantly having difficulty finding apps that would be easy to get on windows. For example, there is not one file archiver even close to 7zip or winrar in functionality. It's extremely frustrating.

The only thing I really like is mission control and spaces, but that's about it.

But the hardware, man that hardware is nice.

My captivate is also now a music machine. The S3 I have will probably be the last phone I acquire for quite some time even though the Galaxy IV is apparently coming out this year.

My Atrix (ahh, Wolfson DAC I <3 you) has the best sound with my TDK BA100s, pretty close to my 5G iPod (nice to know how far we've come in 8 years :rolleyes:) but I know a lot of amp circuits don't impedance match too well with balanced armatures (e.g. the One X simply won't produce past about 12kHz, even with the EQ at that end set at +9dB!) Still, I honestly find the N7's output quite tolerable. I don't need any EQ, which is always a good sign, soundstage is quite expansive, and there's good depth and seperation with pretty much any instrument. Considering the fact that I don't even use lossless on the phone, I don't think investing in HP amps and DACs would really be justified for me... (By the way, is there a lossless format that plays nicely with a non-crappy Android music player? I tried some FLAC and Apple Lossless, both of which andLess played, but andLess has a hideous UI and is an unstable POS. I couldn't find anything else that would play 'em. Mind you, I'm not sure I can really tell the difference between downconverted 320kb/s AAC and the original lossless files I keep in my library anyway... Perhaps it's all a massive waste of disk space for my placebo-prone ears.)

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

What version is for 4.1.2 ?
[Nexus 7 Android Development] Azurael:
I've given up caring. On my Nexus 4, I've seen scores from 15k to 21k in Antutu depending on kernel and ROM, and between about 12k and 16k on the N7 but can I tell the difference in the real world? Nope. lol. I don't think there's such a thing as a 'good' Android benchmark. They all seem to be bipolar, with the possible exception of Vellamo where the score only seems to change a little, dependant on WebKit updates and optimisations. But even its results seem to bear little relation to actually using the browser. The biggest difference I've 'felt' on any device came from the Krait-specific Bionic optimisations found in certain ROMs on the N4.

The particular combinations of ROM and kernel I'm using on my devices are based on real world use and are to some extent a compromise between performance and battery life (e.g. Trinity gives me very good 'feel' on both the N4 and N7 but is also a massive battery hog on both, so it's out. M-Kernel gives me by far the best battery life on the 7, but without a noticeable compromise in performance vs. the others I've tried.)

Edit: Plus, if you care more about benchmarks than actually using the device then flash 4.1.x, it always seems to score higher than 4.2.x for me.
