Default min freq? - Nexus 7 Q&A, Help & Troubleshooting

Anyone know what the default min Mhz is?
Sent from my Nexus 7 using xda premium

on stock, cpu spy informs me that the steps are:
deep sleep, 51mhz, 102, 204, 340, 475, 640, 760, 860, 1000, 1100, 1200, 1300
I am currently using the Modaco rom, which i believe has the stock kernel

Underclocking?

Why is my aria automatically underclocking itself everytime I lock my phone?
Sent from my HTC Liberty using XDA App
Since we're on the subject, does anybody know what mHz the arias cpu underclocks to when its screen locked/screen off (with NO music player or calls or anything like that going)?
245Mhz if I'm not mistaken.

Just to confirm. My CPU stats show:
245.76 mhz 74% of the time
480 mhz 20% of the time
600 mhz 6% of the time

Because it saves battery and tries to keep the battery maintained at a constant temperature. Your phone works through the "ondemand" mechanism...when ever you need more processing power, your phone will work up to that mHz.

It stays at 245 unless I overclock it back to 600, then when I locked it it went back to 245 and kept doing the same thing.
I had to uninstall setcpu and restart my phone and its fine now

Nexus S 4G / SetCpu

Hey im just wondering what other peoples specs are for SetCpu?
12000-1000 is what I'm normally set at..
but as far as Voltage and Advance settings I don't know to much in these 2 area's...
so just curious in what people do with these options, and if it increases performance?
Kernal: Matr1x 11.5

I usually set mine to 1200 200 set it on lazy and its really smooth and very good battery life. I don't mess with the voltage.
Sent from my Nexus S 4G using xda premium
I usually undervolt and keep the stock 1000 / 100 (usually able to get about -75mV from each level w/ 100% stable. At -125mV I start to notice some instability.)
When I OC though I usually keep the voltage at stock and go 1200 / 250.
Anything over 1200 at stock and I find my phone starts getting unstable - everyone's is different though.
Interactive or Lazy Governors for both.
Currently running NexusBeam 4.1 and Glados 2.2.
Thinking about flashing back to ver. 3 though.
Thanks guys.. you guys dont touch options in advance?

[Q] Overclocking Defy+ MB526 with Quarx CM10 27.10

Has anyone overclocked a Defy+ MB526 with Quarx CM10 27.10 build?
Which CPU Clock and Vsel should I choose? Where?

go to recovery.choose cpu and there will be values,clk1 clk2...clk4
these are the clock values,update them to whatever u need.and set the vsel accordingly,in vsel1 ...vsel4 respectively

I know how to, but I'd like to know safe values first. What happens if I set something wrong?

Use vsel calculator app.will give u optimum values.u can test them by lowering ur vsels 1 ir 2 points at a time .if u lower them too much.the phone will reboot randomly.if u increase them too much.there is a risk to burn the cpu.

I use 300/17 600/32 800/42 1000/52 without problems. To get the vsel I do frec/20+2.
How can I prevent burning my CPU? Is Vsel Calculator safe?

Stay within the safe clock frequency.less than 1300mhz.u wouldnt need dat much.defy is pretty much lagless on 1100mhz.and always set vsel less than tha omtimised value.vsel calculator is perfectly safe.doesnt do anything.just tells u the optimum safe values of vsel corresponding to the clock value by a formula.just simple calculation.nothing more

Calculated:
CPU Freq Recommended Voltage
1100 MHz 57 +/-2
800 MHz 42 +/-2
600 MHz 32 +/-2
300 MHz 17 +/-2
So I should set frequency 4 to 1100 and vsel to 57, right?
And what are Vsel and Recommended Voltage?

Yup, you got it right. Set vsel 4 to 57±2... and freq 4 to 1100.
Vsel is CPU voltage... this is the recommended voltage for the freq u selected.
WAIT... I went to Bootmenu CPU settings and Vsel values are different from Vsel Calculator.
Clk Vsel
300 MHz 30
600 MHz 46
800 MHz 54
1000 MHz 58
Why are they different from Vsel Calculator values? Isn't it dangerous to change voltage values? What happens if I set a totally different voltage?
Sorry for the questions, I'm not an expert of OC...
EDIT: I searched online and I found that voltages are high by default because CPUs are stable at different voltages from phones to phones.
How do I safely determine my CPU's stable voltage without damaging the hardware?
I think you can use the vsel=freq/20+2 formula.
It's always working for me and stable!
My current values 300/17,600/32, 800/42, 1100/57

Its different from vselcalc bcoz it only calculates and estimates that your hardware will run ok with these values.doesnt mean that its your actual values.
You can select any one clock at a time.and lower its vsel by 1 or 2.than reboot into system.and check if it is stable.like you dont face any fc.and reboots.this way your hardware will not damage.and you can find optimum values.if it reboots.simply increase the corresponding vsel by 1 or 2.just try not to go beyond vsel 65.it will not burn.but its not safe.so try to be within 65.. its not that hard.give it a try.i hope this clear things up for you. :thumbup:

I set Clock 4 to 1100 MHz and leaved Vsel to default (58). I saved and booted 2ndboot from bootmenu, and CyanogenMod boot animation showed for a while, then black screen. I removed and inserted the battery and it booted successfully. I played Subway Surfers so I think it's stable, but animations seem slower. Maybe Vsel is too low?
And is it stable at 1.2 GHz and Vsel 62?
EDIT: it's not very stable, it rebooted in the app drawer....

Animation doesnt depend on your vsels...and its safe to go for that.but it wont be needed.1100 is more than enuff

Two more things: which settings does Bootmenu use? If it uses my settings and they are not stable how can I enter bootmenu?
And I read in the user's manual that if the phone heats too much it shows a warning and you can only call emergency, does it apply only for stock ROM or also for CM10?

U can always enter into bootmenu.by pressing vol down at blue led.
And there is no such thing as only emrgency at overheat

I know how to enter bootmenu, but if I set a totally unstable Vsel, the phone should always reboot, so it would be impossible to restore default settings, right? Or does bootmenu use different settings?

Phone will reboot after you are fully booted into your rom.after blue led and boot animation dude

What are your cpu settings?

Currently im running aokp rom on at&t S4 with min set to 189 max set to 1890 governor: intellidemand. What do you guys set yours to?
I run the same thing. Pretty good bat life and performance.

I can reduce cpu voltage on all frequencies by 40 mV but gpu lags at anything above 450 mhz(performance governor), also I'm on doomkernel and I can't properly underclock for some reason...

Mine is 1574 mhz max and 300 mhz min interactive row, stock kernel and @Nut 4.3 ROM..do i need to set on boot the default governor? Battery life is good and not overheating too much while playing NOVA 3..

If you do that all your seffings will go back to default like governors. There should be the option to set the same parameters on boot to keep all like you have right now. I don't know if on rooted Z1 there is this settings but should be because I remember I did all of this with android on different devices.
My Z1 with DoomKernel and the latest Monx Rom
1.7 Ghz Max
300 Mhz Min
Intellidemand and noop
(I see a lot of people are using row though, so may need to test it and see if I notice a difference - that and undervolting..)
Current discharge rate is at 3.2% per hour and that's including wifi never being off, some gaming, instant messaging conversations and emails
