OverClocking 101

Status
Not open for further replies.
I just started rooting again and have been playing around with kernels and themes and have come across a setcpu question for my droid. I understand w

You probably had a profile in use at the time. Either the charging one or your first battery level one as a rough guess. Powersaver doesn't change the max frequency. It simply limits how fast it gets to it and how long it stays there.

I checked that and nothing was checked on the profiles. Oh well just another oddity.

So I'm fairly new to rooting and overclocking but have decent knowledge in the area of most computers. I'm currently running Bugless Beast v1.1 with one of the recommended bekit kernels, I believe I currently have the 600mhz SV, I setup some profiles via SetCPU and I'm getting decent battery life but my main concern is heat. Even with the 600 Mhz kernal I get up into the 116F to 118F while running something like pandora and browsing at the same time. Now I may just be over reacting to what is probably normal behavior but it seams strange to me that a 600mHz kernel would produce this kind of heat. As it has been said many times every phone is different and maybe mine just runs hot. Any incite would be helpful to put my mind at ease.... Thanks.

Is the 116F battery or CPU temp? If it is battery, that is due to using a standard/medium voltage kernel. And if you are using 3G to do both activities, you are doing pretty good actually. If that is CPU temp I wouldn't worry about idling at that temp for an hour at a time. Again though a low voltage kernel would help with that temp as well.
 
I'm no expert, but I am addicted to my Droid, use it constantly and my temp never goes higher than 110 degrees, and it rarely gets that hot. Utilize the profiles in SetCPU and it should help A LOT. Skull has posted some good starting points regarding the profiles and advanced settings recently. Has done wonders for my battery life, performance and temperature.
 
The 116F is CPU temp. The battery temp stay pretty close but lags by about 5 to 10 degrees. Note that that's just eyeballing the temps as I browsed and had Pandora running in the background. I will try to find a low voltage kernel of the same speed, I believe that P3Droid offers one. Thanks for the reality check, I know from my days of building PC's that heat is the enemy but there is more ways in those situations to keep them cool with fans and heat sinks. your guide was very helpful in getting me up to speed for the OC aspect of this.

Right now I have my profiles set as follows:

Base(Set on Boot): Max:600 Min:250 Governor- Ondemand
Charging: Max:250 Min:250 Governor- Ondemand
Sleep/Standby: Max:250 Min:250 Governor- Ondemand
Battery 1: <51% Max:550 Min:250 Governor- Ondemand
Battery 1: <31% Max:500 Min:250 Governor- Ondemand
Battery 1: <21% Max:250 Min:250 Governor- Ondemand
Failsafe: Temp > 47.5C Max:250 Min:250 Governor- Ondemand

Advanced(Set on Boot): 50000,75,0,70
 
I'm surprised you're running so hot never getting above 600 MHz. I use these settings with the P3Droid kernel and my temp rarely even gets about 100. All CPU governors are set to 'on demand'...

Base - 1000 max, 250 min
Charging - 1000 max, 250 min
Sleep/Standby - 500 max, 250 min
Battery <50 - 800 max, 250 min
Battery <30 - 600 max, 250 min
Battery <15 - 500 max, 250 min
Failsafe Temp 43.9C/111F - 500 max, 250 min

Advanced Settings - 50000, 75, 0, 0

*I'm currently sitting at 82.4 degrees. I usually only get up to 100+ when I do excessive web browsing or navigation/gps usage.

**This may already be understood, but I try and keep the brightness level of my screen way down too. I assume this helps keep it cooler.

I think it just comes down to "every droid is different". Sometime I think I was just better off running stock and not knowing whats going on with it but its just a major frustration at this point. :icon_evil:
 
Do you run a lot of live widgets and apps that refresh constantly? That might be keeping your Droid working overtime even when it's in stanby mode, not allowing it to take a break to cool down. Again, I'm no expert like Skull, just spitballing here.

Oh how I know that feeling all too well!

Fear not. I began this quest out of frustration on the lack of solid information. If you were to go back to stock, you will find that you will be getting about the same battery temp but you wouldn't be able to tell what the CPU temp is since that is not built in to the ESE 81 OTA ROM.

And you are very correct. Every Droid is unique. I can't stress that enough.

So start with a low voltage kernel and see what happens. Just remember to do a nandroid backup first. It might cost you two hours of your time to test. And if it works, you are better off and if it doesn't you have more experience and have only lost a little time.

Spitballing is fine, the only widget I have running is beautiful widgets, I've seen it drop at low as 69F during standby but as soon as I unlock is jumps to ~80F. Its crazy...

Actually that is very normal and spot on to what I have seen in testing.

2.1 coming out of sleep/standby has to spend about 10 seconds playing catch up. And the CPU with a standard voltage kernel really heats up quick under that condition.

2.2 actually is MUCH better at coming out of sleep/standby than 2.1. I am grateful that the Android team spent so much time fixing that issue alone.
 
I notice that little bit of lag when coming out of standby. Learned to live with it I guess. It runs so fast once that little hiccup is out of the way.
 
For those that care, see my sig. That is what I'm running and I've noticed an improvement over battery life. I am not using setcpu either. As far as temps goes, I have no idea. Other then it doesn't "feel" hot. But for those that want to know what stock kernel does with 2.2. I'd have no remorse telling you that it runs faster and extends the battery at the same time.
But I think that could also be because I am launching my apps quicker, jit is doing it's thing, and I have picked up on download speeds from 3G somehow (guess baseband update did that) that I don't have my screen on as much. Even w/ more use out of my phone (by simplying playing w/ froyo) I still get longer battery life between charges. And my definition of between charges is once the phone kills itself, do a full battery charge, and remove from charger.
I will not say how many days I can go off a full charge as my definition of use and yours is different.
