Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Yeah sounds like my N9, what were you doing when it happened?

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

i was testing 1375mhz @ 10000 iterations
anyway and to be honest i inteded to burn it up, i felt it lacked some performance comparing what i was seeing from the test results others were posting...

try to be 'safe'

lowering to 1,1ghz with stock voltage, :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Done the same thing :P

Had mine on 1.375Ghz with 1.33v or similar voltage for like a week, but back to 1.3Ghz and a.1275v for me :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

I wonder what clock speed that we can call a safe overclock? :p

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Every chip differs , but I think 1100mhz is the safest , because after 1100 you have to increase voltage on most devices .

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

1300 mhz sr on 1375000 μv is the combination who alows to you to do everything above this settings you cant install or download large files with the first and from the terminal you cant set up easy a file this settings is the limits who you do everything

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

I'm at 1200 sr on and 1300000 voltage.. Want to go higher but i'm afraid that gonna burn it or something. :eek:
That 1300 would be nice number to be. :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

do it no pain no gain:eek:

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

1.3v for 1.2ghz is a bit too much , i'm using this voltage for 1.3ghz sr off , try lower voltages before trying higher frequencies ...

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

By the way, try these as root if you can't download or install large files. It worked for me once I came across this issue.

killall -q pkgmgrd
rm -f /var/lib/dpkg/lock

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

default clockspeed 1ghz @1162500, is that too high?, :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

i seem to be moving right along with 1.3MHz/1.35mV

thought that i had a challenge after testing if so that apply on startup would show.

after applying the apply on startup, seemed i had issues and went into a reboot every few minutes.

once i undid that and then rebooted the device, it was working fine. so i reapplied the 1.3/1.35 w/o the apply on startup and it has been fine now for almost 2 days.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Well, i'm only testing that voltage. Usually it's 1250000 or 1285000.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Seems that most of us are comfortable with 1.3MHz/1.35mV ;)
Nice & fast enough.

I had the N900 on 1.0MHz/?mV. relatively more overclocked.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Here it goes.. 1300/1350000.. Let's see what will happend. :cool:

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

1100 @1162500 , i hope it is safety, :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

lowest stable voltage at 1ghz for me is 1075000 , but it's ok that one too .

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

i try to burn my n9 but nothing is a tiger i try all combination all good stable and strong

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

my final settings i do everything with this

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

it seems that the ones that die like Arie and mine are weak chips with some kind of factory defect
now i'm using my gf's n9 and all combinations work well ...

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

try when opttimize test dont acept calls mesage and mails and plug in the cgarger to phone and with sr off above 1200 all combination works if the test good all good later

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

if the combination voltage and freq is good your phone will works like the wind all apps open at the half of time if the combination was not good even test is good and no reboots you are not notice big diference and its no good perhaps later burning it

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

You´re probably right, the question still remains, however...
What is THE BEST combination?

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Its a non answerable questions.

EVERY piece of silicon is slightly different, so even similar batches could have variations.

Basically the perfect combination is specific to your N9/50 and yours alone.

The best performance is what provides power
-
Do the test at 1.3GHz with 1.28v . 1.30v.. 1.35v .. ... and see what I say
-
the same is valid for active SmartReflex (any energy restriction turn off)
-
make your choice between power and consumption

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

1.3 135 perfect

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

SmartReflex doesn't actually restrict power, it simply tests the cpu using different voltages and whatever is found to be the most stable, it keeps the voltage at that.

Meaning is you use 1.2Ghz with 1.38v it might only ever use 1.27v.

In a mobile device which may be away from a charger for 6-10 hours at a time, this type of voltage control is vital.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Not really, if you use opptimizer smartreflex for the top frequency is disabled on purpose by me and the voltage you selected is used exactly like you selected. The smartreflex switch only enables/disables smartreflex for the lower frequencies. If you don't use 'custom voltage' then I guess smartreflex is still enabled, but you can't go very much higher frequency. You can verify the voltage in the raw output on the main screen.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Ahh yeah, completely forgot that you did that back when this was just a terminal command :P

But I guess that still means im right in the sense that SmartReflex doesn't limit power to your chip then at all for the top frequency, which is where the highest voltage comes into effect.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

yeah if I knew how the other parameters that smartreflex looks at worked I could let it adjust some other frequencies like 1200 and 1300, but those parameters are in hex and not documented so I have no clue. Maybe we can just steal some values from other kernels with faster omap chips, but it might not work well because the different chips all behave a bit different.

These are what I'm talking about:

* @sr_nvalue : Smartreflex N target value at voltage <voltage>
* @sr_errminlimit : Error min limit value for smartreflex. This value
* differs at differnet opp and thus is linked
* with voltage.
* @vp_errorgain : Error gain value for the voltage processor. This
* field also differs according to the voltage/opp.

defaults:

static struct omap_volt_data omap36xx_vdd1_volt_data[] = {
{.u_volt_nominal = 1012500, .sr_errminlimit = 0xF4,
.u_volt_dyn_margin = 50000, .vp_errorgain = 0x0C},
{.u_volt_nominal = 1200000, .sr_errminlimit = 0xF9,
.u_volt_dyn_margin = 50000, .vp_errorgain = 0x16},
{.u_volt_nominal = 1325000, .sr_errminlimit = 0xFA,
.u_volt_dyn_margin = 50000, .vp_errorgain = 0x23},
{.u_volt_nominal = 1375000, .sr_errminlimit = 0xFA,
.u_volt_dyn_margin = 50000, .vp_errorgain = 0x27, .abb = true},
};

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Hmm, maybe see if these SmartReflex paramaters are documented for similar chips? There is a chance that the parameters and hex values are the same across a large range of chips, just to make it easier for whoever makes the chips.

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

My device is acting weird with different versions of kernel modules . With 1.5 version , 1300mhz+1.3v is rock solid while with 1.5.3 it reboots in max 5 minutes if I leave it idle .

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

i haven't had no reboots since i installed opptimizer so maybe i can be quite happy. And maybe, just maybe don't have to be scared to burn my N9 chip..?

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Do it at your own risk, yaaaay, go go go, :D

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Well, i'm "only" at 1200/1250000. :)

Re: overclocking kernel modules + UI for PR1.2 [ko v1.5.3] [ui v1.2.5]
 

Im at 1,1ghz / 1162500/default voltage

Exactly same thing happened to mine with same freq same voltage. Stable without reboot for a week with old version of module but reboot within few mins in idling. Need to bump up voltage to 1.35v to make it stable without reboot
