Did you try to undervolt Memory Frequency? - Galaxy Note II Q&A, Help & Troubleshooting

Hi,
we also talk about CPU/GPU undervolt but i never heard someone who tried to undervolt the memory RAM/ROM ? In order to increase battery life.
I'm afraid of triying because no one tried yet, isn't ?

Majority of power goes to cpu and gpu and display. So there is no point on undervolting memory.

Hi
Are you sure? If you look at Stweak example for Cpu at 800mhz you have about 1015mv and memory get about 1000mv so it's around the same volt. I conclud that memory drain some battery ??
Thanks

You can undervolt memory, just take a look at the Memory/Internal section in STweaks.

You can but you will have hard time figuring out stable values

Ok thanks guys.
Did anyone tried to do this? ??

Stock vs Overclocked

Is it worth rooting my phone and overclocking it?
Is overclocking it really noticable in performance to say approx 1.5GHz? And is it going to kill battery? Thanks

Yes and Yes to both of your questions. There is a noticeable diffrence in performance when overclocking. But it will obviously use more battery
cant say ive noticed 1.5ghz killing my battery.. might be used a bit faster.. but u can easily offset this by lowering your clockspeed and voltage for your sleep state in addition to minimising the required voltage that 1.5ghz requires, id say my battery life is probably better overall, and i run 1.5ghz 24/7.
of course your mileage may vary depending on usage and various settings.
How hard is it to overclock it? My phone is rooted but I have no experience with overclocking.
I'm guessing it wouldn't be a wise idea?
Yeah this seems a little over my head.. thinking of buying another Xperia Play just to mod the crap out of.
Dont really wanna mess with the overlocking now I think about it incase I fry the chips and kill the phone.
At 1.4 and 1.5ghz its quite safe.
To chill out the battery put some screen off underclocking like at Real low with but not the least
1. 4 ghz scaling interactiveX I get 252/282 MS, thats pretty fast with nitro lag Nullifier too

i currently overclocking my play to 1.6ghz and it runs fine.. games and apps run a lot more quicker
i'm quite interested in overclocking.. been thinking about it for the last months..
but i don't know, 1GHz is quite enough for me.. im not experiencing any slow down..
Well with 1.5Ghz then, you'll be amazed!

Uaed same but not recommended, when you see problems cool it
I used the XDA App to post this, what did you use?

Undervolting//how low can your phone go :D

just a little information/ competition to see which SGS2 is the best , i want to see how low of a voltage you can go. I am using Stability test to test out the voltage, 3 round of classic test at 1.73ghz at 1125mV, and it stable, a little scare to go down more but here some info on my SGS2
running
beastmod 4.2
kernel 2.3.6
Was running originally at 1175 but i undervolt to 1125 and running stable at a stable temp of 41-42..
what's yours
be careful with such drastic undervolting at those frequencies, could result in corrupt nand.

This isn't undrevolting..... this is underclocking.
Undervolting is pretty dangerous with trial and error. The lowest I'll go is -75.
And my frequencies at min 384 and mas 1350 ondemand

no underclocking meaning i would use less ghz than the stock, this is minimizing the voltage on the core.
what your doing is underclock, i put mine fixed on 1.73ghz at 1125mV of voltage

I have never heard of such thing, i'm not doubting you but from over the years, i heard undervolting have positive affect on the CPU by lowering temp and give battery more juice.
where did you get those facts from?

Ohhhh my mistake, I didn't catch the mv after the 1125 lol that's why I thought you were only messing with ghz ha ha ha

As far as I know, there are no dangers associated with undervolting. I run at those frequencies too at -112.5 and have never had a problem of any sort.
I run about 1ghz. No under volt with this ics kernel but with my old gb kernel I undervilted with faux -100 at 1ghz...ran cool even with games and video, great battery life. And honestly 1ghz is plenty for snappy fast speed

i also run 1ghz, runs super smooth across the board

How did you undervolt by -100?

I don't know if you're familiar with overclocking, but the same type of stability issues can occur. When you're undervolting you can think of your stock speed as an "overclock" and you're just trying to minimize the voltage necessary for stability. If you undervolt too much you can experience freezing, corruption, bad lag, etc. It's all the same process for desktop computers, laptops, and anything else you can play with the voltage.
Personally I'm at -62.5, but after seeing how low people are going I might be a bit more adventurous. Don't use the "Set at Boot" option when you're experimenting.

I did it gradually...and the fact that I was at 1ghz might have also made it possible. Started at -50 since most had said it was safe...then tried 60 then 75 then 90 then maxed at 100...worked beautifully.
I have heard and it is true that phones are made very different. Some exact same models can't oc or UV as high or low as others...I got lucky with a really good model...my old nexus S couldn't oc to 1.4 without freezing while others could.

My bet is he used romanbb's FauxClock (which maxes out at -100mv).

Right, I meant that there are no risks to undervolting in terms of physical damage to your phone, only stability issues which is fixed with a reboot, assuming you didn't set at boot. Overclocking is a bit different in that the risk overclocking presents in addition to stability issues is the risk of overheating which can permanently damage your phone. Undervolting can compensate for this somewhat by letting the power supplied to the processor and thus reducing the risk of overheat.

I use system tuner, you can also look for Gideons script that is flashable in cwm to undervolt.
Im undervolted to -75mv for quite some time running a script clocked at 1.518min384

I have Gideon's OC/UV script. How could I edit it to undervolt by -100?

overclock gpu

Any app for overclocking GPU?? not cpu .. i have yoon kernel.
Sent from my GT-I8150 using xda app-developers app
No and there will not be one as the GPU can´t be overclocked. Why don´t you get familar with Snapdragon rather than asking such questions?
And btw. to incrase SD Card performance simply buy a faster one.

Bioshock 2.0 faux settings

Anyone with knowledge of any of the settings on kernels and what they do our mean I would love some help so I can further understand what to tweak and what the limitations are. I bought faux clock, probably shouldn't have since I'm cluelessv to what I should change because I get reboots undervolting too much or over clocking. Mpdecision I have no clue about. Noop/row/zen ect ect no clue. Thanks anyone. I'm on bioshock 2.0 and want to try and max my battery life.

---------- Post added at 03:54 AM ---------- Previous post was at 03:53 AM ----------
I've found that undervolting by more than 50mV doesn't agree with my phone. At -50mV I do notice that my phone runs cooler, haven't done enough tests to see the difference in battery life though.
Also trying to set up a performance setting or wondering if that would even help with the streaming of movies to my ps3 through dlna file sharing. Thought overclocking would help. No use vi just can't figure it out. Any ideas on that issue?
Sent from my SGH-M919 using xda app-developers app
I can't think if any reason for using the performance governor. That causes your cpu to run at max frequency all the time and would be terrible for your battery. Would also cause your phone to get verrrry hot. For things that require good performance you're best off using on demand. Overclocking could help i guess but I've never had the need to overclock... Then again I've never done what you're trying to do. Can't even imagine the need to overclock a quad core phone clocked at 1.9GHz

Overclocking and undervolting CPU/GPU

Ok, so I'm currently unhappy with my battery life. I used to underclock the CPU on my HTC Evo but im not sure how to do this on the S3 i found a guide under the I9300 for this but i need to know if it is usable for our device as well. Also, curious as to how overclocking the GPU affects battery life. Is it the same as overclocking the CPU or is there little to no change? Also i want to know the most common voltages used as well
