negative digital gain is under eq extras which is under eq settings and eq settings like eargasm etc works for headphones only.

so that won't work for speaker tuning under speaker amplification.

Strange, your ROM lacks the 'free' command !?

But zram is active, it's in the swaps.

JP.
[Galaxy S III Original Android Development] danarama:
Ill be honest I don't trust it. My standby is apparently 1 - 271 mA
[Galaxy S III Original Android Development] Yank555:
Not exactly, zram is not compressed RAM, it's not that easy.

Zram is 150Mb RAM taken away from RAM (you loose it !!!).

In those 150Mb a compressed swap filesystem is stored.

This is activated as swap, virtual memory.

Hence, with zram you loose RAM and get swap instead, but more swap than 150Mb since it's compressed.

Add to that the bad way swap works on android if swappiness is anything less than 100, the maximum... (default is 60).

Hard swap, to work efficiently, needs a swap partition, not a pagefile. A pagefile adds filesystem overhead plus filesystem fragmentation (not really an issue on an mmc memory), which makes it slower than a plain partition (block device).

Since I don't think it's a good idea to repartition internal memory, I would advise putting the swap partition on a fast sd card instead, easy to partition with no risk attached !

Plus the heavy I/O generated will wear the memory faster, and it's better to replace an sd card than internal memory, in the case you wear it out and it breaks.

[Galaxy S III Original Android Development] gaetanolip:
essentially, in your opinion zram eats up ram, isn't it?

yuou prefer swap, in order to increase the number of apps 'active' , alive in ram and not killed , essentially better multitasking..

but, if low memory killer threshold values don't see swap partition, how swap can prevent apps to be killed ????

Going back to stock kernel because I'am being crazy about games that give black screen after

http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache

basing on that swapping to sdcard(external) is slow we already know that.

that link has said for faster systems we don't need swap and compcache.

but if the devs find out through their tests that it improves sgs3 overall, they will have to find where to put swap.

i think even the fastest ext-sdcards won't be able to handle it in giving an unnoticeable slowdown.

the fastest sdcards right now have at least 10MB/s write speeds right? anyone here think that is fast enough to be used as swap?

i was just thinking of internal sdcard, the 11gb usable or whatever's left of it out of the 16gb, since that is definitely faster than extsdcards.

now the question is your concern for the internal memory's lifespan, can someone please confirm that reading/writing of at least 150mb data putting swap to internal sdcard is bad for it?

Can someone give me siyah 1,5 Beta 3 ? I deleted it :( but. Now i want to test it again with Dark knight
[Galaxy S III Original Android Development] Yank555:
That is the very good way to start looking at this, with a critical approach ;)

Here I go :

If you set parameters correctly :

low memory killer limits : they can be changed (I do it in my hard swap mod)

swappiness to the maximum 100 (I do it in my hard swap mod)

You will see more RAM being used (the free part will drop lower, though never to 0, that would be a bad idea), and you will see swap getting used quite a bit, too.

Let me explain why.

Memory is devided into memory pages, that hold data in RAM. Each time a page is accessed, the system flags it with a kind of time stamp, to signal this one has last been used at xxx.

Swap is a container for memory pages to put them away while not being used.

System will start pushing pages unused for a certain amount of time to the swap, and once they are in swap, the memory page is free to be used for something else. How fast this is done is defined by swappiness (from "0 don't swap" to "100 swap to the max").

Is that page requested again, it will have to reload it from swap to push it to an available memory page in RAM, that has a cost. So swapping too much can be bad, it's all about balance, and that may be different depending on the way you use your device. Plus consider swap exists in Linux for computers, servers and eventually we can use it on our phones.

Now you see the cost to use zram :

1) Less available pages in RAM (since you use 150Mb to hold zram)

2) If you don't set swappiness high enough, the system won't swap much, hence not really use the swap at hand (so the RAM you invested to hold zram isn't even used, wasted actually)

3) To free a page in RAM it will need to copy the page from RAM to zram, that has a cost, had you had more RAM and not needed to free that page

So zram is neither "compressed RAM" nor "more RAM". It's RAM used for a RamDisk, used as swap partition.

i have played spiderman and tdkr using stock and siyah beta2 and 3 default or undervolted no black screens.

i'm not talking about oc'ed since those who complained with black screens didn't mention oc.

don't know about beta 4,since i removed it after seeing battery drain.

if you already flashed siyah kernel try to play first with default settings.

then when you want to overclock, try oc'ing cpu first and not everything like including gpu so that it will be easy to troubleshoot.

then when you find everything working if you feel you can still do better you can backread a few pages back and see if the users posting their clocks and voltages have the same roms and siyah kernel versions as yours. if yes then copy their settings and see if it works for you as well.
[Galaxy S III Original Android Development] marck1991:
here it is :)
[Galaxy S III Original Android Development] Yank555:
Let me put it this way :

Memory has a Mean Time Between Failure (just like hard drives), meaning they will break after at least xxx write cycles. So yes they may break down at some point. Another reason not to flash too wildly actually ;)

Now on the other hand, nowadays hard drives are replaced by SSD drives where speed is required, I mean in enterprise computing, which is basically the same kind of technology, so they don't go bad that fast either.

A good SD card is absolutely fast enough to hold swap, remember swap data are the memory pages that aren't used much which are put aside so the really fast memory, RAM, can be freed. Swap is best if it's held on a fast device, but on a computer system, it's held on a harddrive, even on server systems.

I've been using a class 4 sd card as swap container, and my phone flies way more with than without it.

My biggest issue with zram is that the goal is to have as much RAM as possible, so zram is a nogo for me. I then rather add some slower swap to free up faster RAM :D

[Galaxy S III Original Android Development] TMaLuST:
Guys I have a problem with 1.5.4 beta and 1.4 version of this kernel:

I'm running latest cyanogenmod 10 03/08 rom.

I was trying to undervolt the gpu in stweaks, and obviously i took it too far away and my phone froze.

I then decided to run the reset profile zip, but it seems that it doesn't work: my phone freezes as soon as the boot is done.

If I change kernel everything is fine, but I'm assuming that the resetdefaultprofile isn't working with cyanogen10 roms.

Is there any way I can remove the gpu undervolt profile in stweaks?

Thanks

Beta 2 was the same problem for me so all the siyah kernels.

And it doesn't matter if you have OC it or not just change some settings and restart phone removed

savegame deadtrigger and black screen Dark knight and Nova so far.

Tried stock kernel with mobileOdin but phone hangs on black screen after startup so flashed back to beta4 but game problem is still there.

Only sollution is remove game and reinstall it again with data then DONT reboot your phone.

Oh yes save your save games (data/data/.... folder name of the game)

Hey, I do use cool tool, but I haven't used it much in a while.

I discovered that Swype Pad is costing me some performance! (which sucks since I use Swype Pad a LOT and their developers don't really answer emails...). With SwypePad enabled I score around 40-42fps. When it disabled I get around 44-46fps. But I'm still missing around 4fps! I have no idea what could be causing it! I did notice MaliStatus drains a lot of performance!

I think I maybe need to nandroid, install a fresh rom, and install like ONLY siyah and basemark and see what happens maybe :P

The only other services running in the background apart from some normal google ones are: whatsapp, hotmail, swiftkey 3. Really can't see what else is reducing GPU performance... I even tried uninstalling ChainFire3d driver!

Does anyone have ANY ideas? 0_o

Well,I dunno how you guys have these problems.You must be doing something special. :p

Just joking,but I'm not having any problems with black screens and saved data being deleted.My problem is elsewhere.I just played NOVA 3 for about 1 hour with my GPU at 666MHz with 1075mV.Not a glitch,all was perfect(And battery didn't **** all over me).I played Dead Trigger for like 5 minutes and it was freezing for a second every 4-5 seconds.It was awful.Like trying to race a 40 year old car or something.Then I upped my voltage for 666MHz to 1100mV and it played smoothly.700MHz with 1100mV suffered from the same problems however.Now,if you ask me,NOVA 3 looks more demanding on the GPU.Quality of graphics is comparable between the two,but NOVA 3 has much larger environments and all the effects from the *Tegra 3* version of Dead Trigger(which I run),like rag doll physics and overheating gun barrels.So it's a wadafuq situation.Will see how it goes...

PS:Smart Statusbar also affects GPU performance negatively.

I don't think, there is real difference between swap file and swap partition on flash card + it simpler and not dangerous.

I'm using 100m zram and 256 swap.

Seems to be stable and smooth and my GPS navigator was not killed by incoming call.

I hope zram has more priority or op can provide a way to set it separately for swap and zram. Also I'd prefer less than 100M amount of RAM for zram.

You're entitled to your oppinion :laugh: Mine's clearly different, though ;)

Maybe you're not taking into consideration the difference between swap residing on a filesystem vs. on a block device.

As for swappiness, take into consideration that Android Low Memory Killer impeeds linux kernel to swap efficiently by killing tasks before RAM gets low...

I've been running with these settings almost since I run Android, on 4 different devices, without any issues and devices behaved as expected ;)
