Re: Overclock the N900?
 

well I've heard that the safe overclock is around 1.15 GHz so really it's your fault...

Re: Overclock the N900?
 

well, tried to load starving... it just shuts down once starving is loaded...

guess i'll stick to xlv/ulv/lv for the moment

Re: Overclock the N900?
 

yes mine too! After ocing it to 1200 also even limit is only till 1150. Opps! I forgot! After OCing I placed it beside a candle covered with fireworks for christmas.

Re: Overclock the N900?
 

Mine goes all the way up to eleven. So there.

Re: Overclock the N900?
 

Hi guys, i'm new here. I did the OC of my N900 and i'm using LV with 250-850Mhz profile. And I would like to try to Fix the minimum and Max frequency to 850Mhz. I know how to do it, thanks to jakiman, but i have one question. What would be the overall effect of this fixing the frequency to a single value to the Battery Life? would it drain a little bit faster? or it would help lengthen the battery life of my N900? please clear this thing out for me. thanks.

Re: Overclock the N900?
 

I can't answer your question theoretically, but in practice I have mine set for max 900 and min 900 and don't see any difference in battery life.

Re: Overclock the N900?
 

The auto-scaler is pretty well tuned on the N900 to adjust between 4 or 5 ranges.

I do know that when some of the initial testing was happening (back in the 40 to 60-ish range in this thread?) it was found that using any setting below 250Mhz could cause instability, and that "optimal" energy performance was at 500Mhz. Using 500 as a min (with lower voltage) seems to be a theme in most of the pre-loadable profiles.

Personally, I have a 4 tier setup: 500, 650, 800, 950 and battery tends to last me 30ish hours with normal usage, 50ish hours when mainly on standby (eg light texting, no major browsing, etc).

I don't think setting it to one frequency will buy you much, and may actually reduce battery life. The built in scaler is pretty efficient at what it does, and it's running even if you have only 1 state (because technically, you always have two, with one being 0, or "standby"). All of this is based on how you use the device though, so the "best" settings will be different for everyone.

Re: Overclock the N900?
 

hi,

First of all. BIG THANKS to the people who have been working and assissting on this project! you guyz have made this community great :)

I am new to overclocking and linux but i am a good leaner ;) I overclocked my n900 with the min and max frequencies set to 125 and 950 respectively. using conky i realised my frequency still never goes below the stock min frequency (250) even though i have set it to 125.. i did try kernel-config show in xterminal and it does say that the min frequency is set to 125 but according to conky its not.. is there anything that i am doing wrong?

btw can anyone advice me on which min and max frequencies are best for performance and even better battery life.

Thanks all :)

Re: Overclock the N900?
 

Hi.

I've overclocked my phone and now I have a problem with the wiimote.

I play with DrNokNes with the GameGripper or the wiimote usually and never had a problem, until now.
Today I've tried to play with the wiimote but only could play for over a minute or two, after that a "lag" appears: for example in Super Mario World I press the left button and Mario moves to left ONE SECOND later, so it's impossible to play.
If I play with GameGripper or N900 keyboard all works fine, I can be playing for hours with no problem.
I've changed the maximum CPU speed between 250 and 900 MHz (250, 300, 350...) and the problem persists.
Finally I've uninstalled the power kernel and wiimote works fine again.

Could it be a bluetooth problem? I think not. I can send files via bluetooth with no errors.

Re: Overclock the N900?
 

If the problem was really due to overclocking, the pattern should go: overclock, you have the problem. Turn off overclocking, you don't have the problem. Turn overclocking back on, you have the problem. In other words, it's easy to stop overclocking, so it would be easy to test.

Unfortunately, you seem to really be saying that this has to do with the power kernel. At the same time, you seem to have been running with the power kernel before today (true? it's hard to tell from what you said) and just got the problem today. That would rule out the power kernel, if what I just typed is true.

The question to me is, does anyone else running with the wiimote have the same issue with the power kernel?

Re: Overclock the N900?
 

Hi, thanks for the reply, I am now using the IDEAL profile with 500mhz(Min) - 850mhz(Max) limits that goes with the ideal profile.

current freq: 850
min freq: 500
max freq: 850
avoid freq: 125, 250
active freq: 0:30,90 500:30,360 550:33,400 600:38,430 700:45,430 750:45,430 805:48,430 850:48,500 and so on...
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0
GOVERNOR=ondemand
UP_THRESHOLD=75
SAMPLING_RATE=150000
IGNORE_NICE_LOAD=1
POWERSAVE_BIAS=0


As indicated on your post, you have a 4 tier setup with 500, 650, 800, and 950 as your only active frequencies? and the rest are in avoid freqs? am i right? My question is, are there any factors do you need to consider in choosing what frequency to skip and to be included in the avoid freqs? like in my case, running on a 500mhz-850mhz only with IDEAL voltages of titan, how would i know what freqs can be skipped and avoided? And lastly, what's the explanation for these skipping/avoiding frequency steps between your min and max preferred freq? what are the possible benefits of it? please enlighten me again once and for all. :D

Thanks again, and in advance.

Re: Overclock the N900?
 

Well, Today I've flashed the phone and installed only the programs needed to play DrNokNes with the wiimote: DrNokNes and wiicontrol.

I've been playing Super Mari* W*rld for about half an hour with gamegripper, keyboard and wiimote without problems.

After that I've installed advanced power kernel and qcpufreq, shut down and reinit, configure qcpufreq witch CPU max speed = 900MHz and start to play.
One minute later the "lag" appeared. I could play with the keyboard and the gamegripper (no lag), but with the wiimote was impossible because of the lag.

Reboot, verify that qcpufreq hasn't modify the CPU max speed (600MHz) and try to play. The lag appears again.

Uninstall advanced power kernel, reboot and play: all works fine.

I've repeated all the steps with the nes emulator (iNes) and D*nkey K*ng: the same problem.

So I think that the problem only can be the phone, wiicontrol or the kernel.

Am I only the one who has this lag?

Re: Overclock the N900?
 

I have different issues with power kernel. In the latest kernel 46, I get random shutdowns regardless of speed. The phone simply shuts down with no warning and then refuses to power up until battery removal. Always happens when phone is locked in pocket and moving around.

Another issue it developed at some point is incompatibility with some software. E.g., late kernels (don't know if 46 only) are allergic to alarmed (a python app). Installing it gets me the "telephony functions (including emergency calls) are disabled" on boot. Skipping alarmed did not yiels the error any more.

And, after installing some new software, I get the telephony error about 20 minutes or so after boot. Boots fine, I can call, text and link up to 3.5G, and after a while I get "telephony functions have been disabled due to a communication error". Needs reboot.

I was ready to return it, since it does it at 600 MHz, but after installing multiboot and backup menu multiboot I booted to stock kernel and it's rock solid for 48 hours straight. If slow.

Anyone else has any of these issues? What could possibly get me the telephony error? Can it b fixed without reboot? Is it a problem withthe modem driver equivalent?

I have seen this problem several times on the forum and they all result the same, reflash. Reflashing stock kernel fixes it but it's not really a fix, plus, it seems t indicate an issue with power kernel.

Help?

Re: Overclock the N900?
 

I don't know, but I can tell you that I'm running kernel 46 and Alarmed and I don't have the problems you describe.

Re: Overclock the N900?
 

It's truely a pain. I have no idea what I would have done without BackupMenu. I flash and I flash.

Odd thing is, it's predictable. I made a batch that restored my settings and installed my software and running it makes telephony fail.

I have since long lost hope of figuring it out, I was hoping for a cure to the symptoms? Say, reconnect with modem driver or somesuch?

Would a logging system help with my sudden death N900 sindrome? Maybe with my telephony problem?

Re: Overclock the N900?
 

@ndi

is your telephony problems occur after you restore settings via backupmenu?

-im no expert but my Galaxy S has the same problem after I flash and restore full settings and ROM. the way i was instructed to obliterate the problem is to reflash the modem.bin file which is kinda telephony file.

hope this gives relevant info....

Re: Overclock the N900?
 

I can trigger it by restoring rootfs without restoring optfs under some circumstances. I don't see why, I was thinking maybe it's an alarm daemon issue.

After consulting a few gurus I realized that the alarms get registered with the hardware, so the phone can wake when off, so a corrupt alarm thing could be it. I haven't touched the alarms but with calendar and other stuff who knows.

It could be the source of my pain and why it's so unpredictable.

As for the telephony driver isn't that flashed with a normal flash?

Oh, and, Calendar is out of whack because when the phone powers down and I have to remove the battery 9/10 times it forgets date, time, area and so on so I jump time back and forth like nuts, on a daily basis. Data logging apps are destroyed. Battery eye has negative statistics.

Anyone know when all alarms are synced? Enable and disable all alarms and enter-exit calendar? Restart? Spy on alamque.ini or whatsitsname?

Re: Overclock the N900?
 

Maybe a loose battery contact is the culprit. I have been in the same issue a month back. That's when I bought a new original battery from Nokia and a universal Desktop Charger for my BL-5J and other Li-ion battery. I also had completely no idea why I my phone shutsdown randomly, mostly when the phone is locked in my pocket while I'm walking, sliding up the keyboard, and even when i just hold my phone and tilt it up. Then i found these topics and tried the solution, and viola! No random shutdowns right after that.

As i evaluated the problem and the solution, I guess it all happened because of the universal Desktop Charger that I bought and used to charge that battery. My desktop charger has 2 pins for the + and - which made the contacts loose since it has a larger diameter than the max distance between the contacts of the battery.

Re: Overclock the N900?
 

I thought about it, problem it, it doesn't start again by button. I have to replace battery to start it, so it's not a battery contact.

I am now investigating a CPU freq issue.

Re: Overclock the N900?
 

Don't just think about it. Trying doing it. :D get a thumbtack or pushpin and draw the contacts on your battery closer.

And don't try to immediately power on your device after a shutdown, it has some delays even if it seems to look like it has shutdown already.

Re: Overclock the N900?
 

I have tracked the issue, permanently, to an issue with wlan being either unable to find anything or with with several consecutive failures via syslog.

Also, the issue has 100% repeatability with stock Nokia kernel from PR1.3, so this is definitely not a power kernel issue.

As a result, I'll stop bugging everyone now. I'll reflash (ughhh!) and try to salvage as much data as I can. I wish I could trak this down for the rest of you but unfortunatly I'm losing phone capability every drive and this unacceptable for such a long time.

I'll give it one more shot on the way home and that's it. Reflash.

Re: Overclock the N900?
 

Im running maemo at 850mhz and Nitroid Gingerbread at 900-1150mhz depending to that if i am playing game or something heavy OR just surfing in the net or something not so heavy.

Re: Overclock the N900?
 

Whats happened with Titan? Is there plans on a newer kernel update from v46 to fix issues involving the camera start up.

Re: Overclock the N900?
 

It was that. Multiple consecutive failures in the modem caused the shutdown. The underlying issue was most likely mechanical in nature.

I was a coincidence that it always cored when wifi failed. Failure points were roughly at the edge of wifi.

Re: Overclock the N900?
 

am having a problem were after a reflash my battery severly overheats up to 51c when charging with usb will normal charger is fine. am replacing the battery soon anyway

Re: Overclock the N900?
 

ive been using the power kernel for a long time on ideal.. and something i nticed today is that conky shows the clockfreqs switching between min and max only. if i change the min and max limits, then it will switch between those. All the freqs in between are ignored.
cpu percentage would be 45% for 500mhz and 50% for 1000mhz.

i havent chaned any of the values within the ideal file, so they're all there on the FREQS list. the only avoid freqs are 125 and 250.

whats wrong?

another doubt, if i use the time-in-state script given in the voltage tables wiki, do i have to keep xterm alive. because right now the values are all 0.

Re: Overclock the N900?
 

okay im not an expert but this is how i understand.

Your n900 runs the Ondemand Governor. Which means, the cpu will run from the lowest freq to the highest depending on what the system or a process needs.

Example you're on ideal 500/1000, and you run an app which needs at least 850mhz. Your cpu will elevate from 500 to 850 in an instant.

So i believe....nothing is wrong....

(someone correct me please)

Re: Overclock the N900?
 

but this situation occered when i just had 1 browser and music playing.

Re: Overclock the N900?
 

Interesting story about the varying capability of the N900 CPU.

I was running:
Starving 125 mhz to 805 mhz as my primary profile
Starving 250 to 1100 mhz when I wanted more speed
Starving 125 mhz to 600 mhz for battery conservation

Then I broke the USB connector on my phone and sent it back to Nokia for in Warranty repair/replacement.

My brand new/refurb? N900 I received as a replacement reboots within seconds if I run ULV, XLV, Ideal, or Starving! I have settled on:
LV 125 to 805 mhz for primary profile
LV 125 to 600 mhz mode for battery conservation

Device reboots if I take the LV up to 1000 mhz so I have:
LV 500 to 900 mhz for more speed
Default 500 to 1000 mhz for max speed

I am still fine tuning but I must say I am a little disappointed this device is not as stable at even Ideal voltages. My battery life isnt quite the same as my original device.

This brings up a question: My old device was used for months before overclocking and undervolting. Maybe this one will get better after some use? Do the chip sets "break in" after some useage?

Re: Overclock the N900?
 

From my experience i believe so. my device never even got to ideal last year.. but after a couple of months on lower voltages i was soon able to use it at ideal voltages. now im aiming on the 'starving' values.

Re: Overclock the N900?
 

I don't think so. I've had 4 different N900's so far with different manufacture dates.
My experience is that the first N900's that were manufactured could operate at lower voltages than newer ones.

the exact thing happened to me. My older unit would do ulv 500 to 1000 or ideal the new one I recieved from nokia reboots above anything lv, maybe its power kernel version related?

Re: Overclock the N900?
 

he guys,

Are you guys still satisfied about the overclocking part?

I am running my n900 for now like 9 months on 1000mhz without any probs.

In the beginning they say all people brick their devices, but it's still alive and kicking.

Are there any kills by overclocking already??
My n900 needs to hold it for 1 more year but i think it should do fine, i am also no heavy user with movies and ****, sometimes navigation or something.
So my cpu rarely maxes out, still I never turn back to 600mhz because the difference in overall speed, just alot snappier, faster, and just snappier xD
Thinking about to run it on 1100mhz but's that feels a little bit to high because of the overvoltage.


Greetz out of holland

Re: Overclock the N900?
 

There aren't any confirmed kills due to overclocking and extremely few claims of damage due to overclocking. It would be very diffiicult to prove anyway, because many of those claiming damage is likely keep making their claims lighter. At first they claimed overclocking would likely brick phones in a short time.When that obviously didn't happen, they started claiming that phones would eventually start acting funny and be less dependible. My phone always acted in ways I didn't expect sometimes even before I had even thought of overclocking, and it still does sometimes today. It never crashes and seems to be in great shape. I'm running at 900 mHz tops.

Re: Overclock the N900?
 

btw, are they still manufacturing the N900?
or when was the last manufactured batch?

I'll be interested in how the most recent batched overclock compared to the initial batch.

My 2009 preorder model can do 1.1Ghz no probs.

I wonder if the Q2/Q3 N900 batches overclock much better?

Titan, any chance you can add more speeds to the kernel? Such as up to 1.3Ghz?
(we know the risks and most likely, it'll just lock up and need to reboot if it cna't handle that anyways. So hardly any risk. =P)
