Voltage control settings?

I'm on sfr 1.2 with genocide 1.1 final kernel, what are optimal settings for voltage control for speed, everytime I put it at 1.4 it instantly freezes and I have to pull battery, then when I put it at 1.3 it will be fine foor a little while but if I multitask like using music player the phone freezes and I must pull battery again, what should the speed mhz and voltage be?

100-1000mhz= -100uv....
1120mhz= -75uv....
1200mhz=-50uv....
1300-1400mhz=_25uv....
Going any lower with the high speeds gets me freezes and going any lower with the slower speeds gets me freezes and data corruption/loss...I've been stable for some good time with these settings

I tried those settings and my phone froze within 5 secs.
What do you have the initial front screen Mhz set at whats the min and the max set at?

Every Epic is different. I can run 1400 all day but can't undervolt at all. Some people can't run over 1200. It just depends on your phone. If things are freezing or shutting down on 1300 or 1400, your phone most likely can't handle it

The phone runs great and crazy fast at 1200 or 1300 but i was just wondering if i could get that little bit extra boost to 1400, but i guess if my phone cant handle those speeds im just going to have to be happy with fast. lol

Ill attach some shots of my new settings...I know for a fact I can't go below -100 with the lower speeds or else I instantly loose random data...if ure still optimistic u can try them...question though...does your phone still freeze up with overclocking to 1.4ghz and no undervolting?

Also, (well its probably not recommended) some people have paid for the Extreme key for Voltage Control and OVERvolted a bit to get 1400 stable but I wouldn't recommend it unless Xan says you are good. The option is there though. I have it but haven't had the need to try overvolting

Off Topic: Voltage Control Extreme showed up on my Sprint bill and I giggled.
On topic: I've never noticed any performance differences when I overvolted. What benefits have people gained? I'm using Twilight 1.1.1 at 1.3 ghz and the phone glides without extra power.

I think overvolting may help people whose phone crashes say at 1.3. If you have it stable without overvolting, I wouldn't even mess with it. 1.3 and 1.4 are already using more voltage than what's considered optimal for our phones

I find that hilarious that they decided to give up at 1.0. I know that's recommended value, but my phone never even shows any signs of instability at 1.3. In fact, it seems like it enjoys it better.

SRF 1.2 really makes it just sip at the battery. I can't believe how fast it causes it to charge. Can't wait to try Vision 1.3. I'm going to test out the 1.4 and 1.45 settings.

Im at 200-1000. 200 and 1000 -50, everything in between -75

You can use CPU Editor, It's a script that allows you to force dual core and allows a lot of customization. For instance you can run different frequencies on each core along with different govenors and so on, could be great for saving battery life too.

If you have a dual core processor in your Windows 7 computer and one of the processing cores is disabled, you have the ability to make both cores work again. Utilizing both processing cores instead of just one will substantially increase the processing performance of your computer, which will translate into faster operations.

Root your phone. Download system tuner pro from the app store got to Cpu and change the governor to performance instead of on demand... This will use a lot more battery tho.

I actually wouldn't recommend that, in some cases performance is the better govenor for performance but I heard the S3 or the S4 processor is actually optimized for the ondemand govenor. I did some tests and I noticed that they scored pretty close to the same in the benchmarks department, I noticed that the S3 gets hot when using the performance govenor and then it starts to lag here and there but I did not experience this with the ondemand govenor.
OnDemand:
Scales CPU according to the processing needs of the programs running which saves power and is still snappy as ever.
Performance:
Locks the CPU at the top frequency regardless of processing needs which drains battery and can make the S3 insanely hot.

If you read ops request... He wants to know how to make both the cores work at the same time... And I gave him the right answer regardless of what it does to the phone he wanted to know how to do it and I answered.
Now would I recommend having both cores on at all times absolutely not... Phone drains the batter and gets pretty hot.

Naturally the second core will come on when it needs to based off the type of governor set. As said before performance governor locks at Max. SmartassV2 does not have smp so the second core never goes offline. Simply turning on the second core really won't give you a noticeable difference in performance.
But using root explorer or terminal emulator, setting
/sys/devices/system/CPU/CPU1/online to 1
Then change same files permission to read only will yield an always active second core.

[Q] Seeder entropy generator, does it make a noticeable difference?

Well sorry but it definitely makes my system faster no matter what these other people say. I find for instance that Tapatalk can get hung up quite easily but when I run this mod forums load instantly every time.
So, try it out and see for yourself.

Or instead of using the app (since it murders the battery life) you could just change the min frequency of your CPU to like, 600mhz or higher and it does the same thing as this app

No it doesnt do the same thing. I have my cpu set at 1800 performance and this mod clearly makes a difference above and beyond that.
And it may burn battery a bit faster but it doesn't "murder" your battery. I've been heavily using my phone with the mod on for 6 hours and have used about 40% of the battery. Pretty normal burn rate for browsing, texting and watching netflix non stop.

N7100 Quadrant Scores vs. SGH-T889 Scores, Huh?

Played with a Friend's International Note 2 recently and was shocked to see the Quadrant Benchmark scores to be above 7081. No root, no custom ROM, Pure Stock N7100. I ran the tests on his phone several times and the average was between 6900 and 7100.
Our T889's can only go up to 6400 and on average, 5900 - 6000.
I know these are just numbers and don't have any significant impact on the phone's performance but,
What gives?

If I may speculate, our phones do have extra crap from T-Mobile that's consuming RAM and clock cycles constantly while the international Note 2 doesn't. That's the best theory is could think of. I ran Quadrant earlier and got ~4200 something on my Note 2 while getting ~5700 something on my T-Mobile SGS3.

FWIW, I am running Jedi Master 8 ROM with SaberKernel 8 on a T-Mo Note 2, and I just got 7008 on Quadrant. I don't know if that's due to crapware being left out of the ROM, or the non-stock kernel, or something else, but at least it demonstrates it's not a hardware limitation.

If you are getting in the range of 4000, that's because you have power-saving mode enabled. Disable that! Lol. :laugh:
I honestly don't know what T-Mobile services are running in the background, can you please shed some more light on this.
All I see is T-Mobile's My Account always running in the background.
I always have ~470mb of RAM used of 1.75gb when there is nothing active.
Is the kernel that bad in the Carrier Note 2's?
I don't want to root my phone. :crying:

tmobile roms always score lower than the n7105 roms no matter what i did a test

That was the problem! I guess checking the power-saving settings was an oversight and one that gimped my Note 2. I noticed Quadrant reported my CPU clock speed at 1.1 GHz and I couldn't figure out why until I checked the power-saving settings. Problem solved! :good:
Now I'm getting about ~5800 from quadrant

I have only flashed 3 roms for the last 6 months just became a member. The JDEVIL Roms with no kernel on my phone score around 8500 . Im impressed. I like quads . They may not be 100 percent on real life feel. But you csn kind of use them as a gauge. That OP is a nice guy as well and I like that too

I need to root my phone, lol.

My experience is this...
On stock, I never came across a game that this phone made unplayable by way of graphics, sound or any other phathomable benchmark
On Custom Roms based on my own and others' test all games are just as good, play-wise, but with better battery life and overall phone longevity
Dont get me wrong, some games are just better played with a controller.... if thats a knock on GNII then its also a knock on every other phone made
As far as Xperia, it stock, vs GNII stock, may be better but I know the capability is there with the GNII (emulators will eventually pick up) and if im not mistaken there are already some options available that can bring the GNII very comparable to the Xperia, while also being an overall better PHONE

I just ran it on my stock T-Mobile Note 2 and I got a score of 5671. It's a great score imho, considering I'm all stock and going to stay that way. I just find it crazy how much T-mobile's boat ware lowers our benchmark scores. I find it doesn't effect real time performance in any way. Just that it does mess with benchmark scores. Not really a issue if you ask me.

How much do you undervolt?

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

Sent from my SGH-I747 using xda app-developers app

The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.
