Hi all,
I have read much on how people have overclocked their Wizards. Is it safe to do so? Or does the chip get too hot or unstable?
Thanks
Matt
if you over do it ofcause it can / do
plus the batt last for much shorter
also why do you wanna overclock ?
to speed things up ?
well it will not speed up the speed of the memory and flash and sd card so in the end it may not add much in terms of responsiveness
Hi guys!
I haven't yet rooted my Desire(I would have but I was fool enough to install the 2.2 OTA).The main reason for me to root would be the ability to overclock my device.All this time that I have been around here on the Desire and Nexus One forums I have been seeing that our devices are overclocked only up to 1113MHz and only in very rare cases 1267MHz.However,to my great surprise,I noticed on OpenDesire ROM's thread that the Desire can be overclocked @1344MHz(which of course made me think a big HELL YEAH!).Is that number ok for all of us or for some select few?I remember from my Hero days that only some few,lucky guys like myself could overclock up to 768MHz,although there were cases of people,rare,yet not unheard of,that could overclock @844MHz.Is this the case here or are things different with the Snapdragon?
Many many thanks guys!
C'mon guys,no one?

I don't think overclocking to 1267MHz happens in rare cases. I had no problems oc-ing to 1267 and it seems that a lot of forum member were able to do this too.
Why don't you downgrade your HBoot to 0.80, root your phone and try it out?
Just make sure your phone does not become too hot if you try 1344MHz.
I have to ask the question, but does it really matter?
IMHO, the Desire is plenty fast enough that overclocking it simply isn't necessary.
I can understand underclocking to eek out more battery life, but other than gaining a few points on some benchmarks, I really don't see the point in overclocking.

Dave

so this, its really not needed at all. a decent fast rom and 1ghz is more than enought for things to be super speedy. any decent kernal will provide more than enough speed.
overclocking(and lots of other things these days!) reminds me of that bit in jurassic park where they are all sat around the table and geoff goldblum says:
"Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should".
herein lies the lesson, just because you can do it doesnt mean you should do it.
Well,I have my reasons wanting to overclock...First off,I will check if I can see any difference in speed or smoothness.If there isn't,I will just revert the clock back to normal after some benchmarks.
I just am the kind of guy that wants to get the most out of his phone!
I think ALL Desires can overclock to 1267Mhz. It's not that rare and I've not seen anyone having a problem with it.
It does make things a bit snappier as well.

That's what I'm talkin' about man!
And now that I think of it,it's not that much.I mean,the Hero could overclock @768,which is 45% overclocking.The Desire's 1267 is about 27% and 1344 is about 34,5%.Nothing too much!So why not?
Every CPU is different. The Qualcomm Snapdragon is a very different beast compared to the Qualcomm MSM 7200A.
We are just starting to learn what we can do with the Snapdragon without damaging it.

Well my man,in this case the MSM7200A is no beast but rather a pooch that barks to no avail!Good pet however!
Joking aside,the Snapdragon is a beast for a mobile phone,but even beasts get beaten.Now,if I can somehow reach or even get close to the performance of the Galaxy S or the Droid X I'll be happy.Software wise I believe that HTC is far superior ,but it's hardware is a little out of date.Let's see what their new devices will do for us!
Btw,does anyone know if the so anticipated HTC Ace will be anything better than what we already have or if it will be the Evo for GSM users?
Thanks!
The desire is plenty fast as it is and I don't see the point of overclocking it. I've had it to 1267 in the past and it made no difference at all for usability. I'm also the type that overclocks all his computers...

Personal preferences dude...What everyone does with their phone is their own business.I wish I could resist overclocking too!
However,I was watching a thread over at the N1 forums in which a dude named Storm9999(genius dude,not just a random one) stated that an overclock @1,3GHz could fry our phones.Is that so?I mean,I know overclocking reduces the CPU's lifetime,but is it THAT MUCH dangerous?
I think overclocking can kill your phone.. I use to overclock my own o2 orbit and it died after a year..
Friend of mine just burned his old HTC by overclocking it and as a consequence is going to buy a desire.
I had my phone overclocked at 1345Mhz for a moment, just to test it, and it made no real difference to when it was overclocked at around 1.2Ghz, which in turn has very very little difference to stock 1Ghz.
I think the only case where you see some small impact is in games.
I've tested HD recording at 1.345 Ghz and stock speed and there was no difference.
If anything, it's going to kill your battery and shorten its life for sure, going so high. If ever I will OC again I won't go over 1.1 and only if I find some tangible improvements.
As said, this phone is always fast, there is no real need to OC, other than for 'fun'.
The fun is what I want...Well,most probably I will have my phone overclocked at the maximum speed it can get for about a week or two and then go back to 1 or 1,1GHz...
Btw,your signature kicks ass andycted!
I rarely play games on my phones, and generally even if I do it's something like Battleheart or Tiny Tower or one of the Kairosoft games (and of course Draw Summin and Wordfeud) or a little SNES emu rather than Shadowgun (Gears of Bore Mobile now with more boring) and such.
Reason being that I already play a lot of high end games on PC and console regularly so... the "simpler" designed games tend to be a much better experience on a mobile. Probably a discussion had a million times on neoGAF or something so I won't expand anymore .
So what I mean to ask is that is there a significant gain in UI/Browser/etc performance with 512mhz GPU OC?
Is the additional battery drain significant?
I'm currently on Liquid 1.3 + Franco 142 FWIW
Lots of power drain with minimal improvement. I just stick with the 384Mhz kernel cause it gives me the least problems.

Another phone for a hardcore non-mobile gamer.
Or better yet, a Vita.
Something I've been pondering on for many a day is: How much more performance will I see if I were to overclock the GPU to 384 Mhz?

A few frames per second. Technically it isn't an overclock. It is a restore to reference clock

I know what you mean.
I read that article the Google developer wrote regarding this matter. Are these few extra frames notable in games? Does it use that much more power?
Speaking of "restoring to reference" clock, why did an image of an iPhone pop up in my head? Oh yeah, they underclock their processors by 200 Mhz.

I'm not sure if it makes a real world difference really. I've always done it in my kernels...just because
Is the GPU set solid at 512 or dynamic and will ramp up/down as its needed? I'm guessing set, as one of the Android brains out there would of already made it dynamic if possible.
Think I have answered my own question really in hindsight

Adrynalyne will no doubt correct me if I am wrong, but I think the fps gain from reference to 512Mhz is something in the region of 3-5 fps? It's a lot of drain for very little gain. And seeing how I've not come across a game that isn't smooth on the Nexus, it seems like a waste of time and juice.

Uhhh... I just said I don't play many games on my phones at all. To make it even clearer, I don't play games when I'm out besides simple ones because I generally rather read something online if I had a lot of time waiting for something/someone since I do so much, dare I say it, proper gaming at home. My mobile is my mobile, it's why I got a gnex, it's a smartphone .
Back to topic, so 512mhz is only a little FPS increase in games (that I don't play ) with minimal gains everywhere else and generally lowers battery life? I'll remain stock clock then . Thanks guys.

I agree with your completely
307 to 384 nets me 3 fps.
I would imagine 512 from 384 has diminishing returns from that. So 3-5 is not a stretch at all for max gain.

Well i have a phone, and in that forum members says that Overclock the cpu shorts the motherboard life, is that true? and for those who are using Overclock, do u really feel something diferent with the performance of the tablet? or do u see something wrong with Overclock? like random reeboots or makes the tablet hot? Im thinking in OC or not my tab, so i wanna see the experience from other members, thx in advance. :good:

I cover this in the guide I wrote in general (which has been pushed down quite a ways) but anyways here goes another version.
Overclocking varies from device to device, even of the same model. Variances in tolerance is on a per chip basis, as long as they pass within a certain range they are sent out for production in devices. Overclocking in general is within means of the chip's abilities, if it isn't, you'll know it. Generally speaking, 1.4 GHz is perfectly fine on our devices. 1.5 GHz is also usually ok, but is the upper end of what the Tegra2 can usually tolerate. Few an go past 1.58 GHz, my old G2x's tegra2 could hit 1.7 GHz,but that's well beyond "normal" range.
Overclocking a device is the same as overclocking a PC, you need to be careful with it. Don't just ramp it to 65% overclock and expect it to run fine. Every chip is different. Do it in steps, and test each step before moving on. Test it in normal usage, test it in heavy usage, gaming, etc.
An overclocked device will certainly run hotter then normal, it's running faster, drawing more power, and that creates a hotter running core, no way around it. Keeping in mind there is no airflow in these things, that makes the biggest enemy to CPUs even more dangerous.Does it run so hot that it can shorten component life? Sure it can. Will you still have the device when it happens? I doubt it. Likely, we'll be on Tegra5 before it even begins to show signs of stress.
One of the nice things, though, is our CPUs range so much in speed according to load that just because your Max is 1.5 GHz, it doesn't always run there. Most times, it won't even be in the overclocked speeds. Does it run faster? Sure does. Benchmarks will raise nicely, and games that maybe got choppy before will smooth out, movies that couldn't play well will be fluid, the heavens will align, mankind will discover world peace and I'll win the lottery.
All that being said, I don't usually overclock, in fact I tend to underclock a little to 800MHz. Its usually sufficient to do normal tablet stuff, and I adjust the speed according to what I require. If my movie is lagging, I'll bump it up until it smooths out. Same for a game if it needs it.
In the end, its all personal choice, really. Just because you CAN overclock, doesn't mean you NEED to. IMO a well tuned governor will give as good a result as overclocking in normal usage, and a good I/O Scheduler will also help alot, without adding anymore heat or stress to your device.
TL;DNR:
Overclocking is fun. It causes more heat. It likely won't explode within the time you own it. Or your children. Your battery will suck.
thanks pio for the answer, thats what i needed to read, cuz usually when u talk about OC its like "yeah dude, OC its "tha greeeeeat doi it dude" or something like "dont do it!!! u will decrease your tablet life" and yes, i know that devices are way to diferent even if they are the same model, and also im agree with u, governors and I/O works better than OC but we dont have many for our device, i miss the smartass v2 governor,or the brazzilianwax too, but well, hope someone can port it for us someday.
Hey guys i saw this video on youtube (http://youtu.be/5nrOWZUsEEc) that explains that undervolting wont make your phone save battery life more than 2% even with EXUV. I need explanations for this as i don't really understand.

Well, i don't really understand WHY it doesn't save more than 2% of the battery life. Afaik, EXUV does reduce heat and improve battery life by miles. But that's what I thought. In reality which is this, im not rly sure why that even with EXUV, it still cant save more than 2% of the battery life.

I'm not technically expert with things like this but I have read an article/ blog before that undervolting may damage a phone since it was designed to work with that specific voltage. So, I actually didn't do that even UC or OC. Just saying.....
Undervolting doesn't save battery as your CPU will still try and draw the manufacturer set levels.
If it doesn't get those levels it must step down its own level which essentially means that the activity that needs processing needs more time, and consequently, more battery.
Even if you manually adjust the clock speed of your CPU down to match your new voltages, the same applies.
UC/UV is quite simply the worst voodoo that persists across these forums.

we can control the hardware through software so we can control the voltages and frequencies through kernel
devs can put new frequency levels as manufacturers did (like this :https://github.com/Christopher83/samsung-kernel-msm7x30/commit/899d5a296a43a6d32c2468bba8121c3a1915dd68)
if its not true and if this method doesnt work, Why all kernel devs on XDA trying the same thing??
https://github.com/faux123/android_kernel_oppo_n1/commit/eaa6639979e1144f28c14e6de48994d41e5d20d8
https://github.com/franciscofranco/hammerhead/commit/104890313a73dae0e7d7a13975801cc568d231ad
in summary EXUV and UV are absolutly battery-friendly
and do not forget undervoltage cant damage the hardware but overvoltage(ı mean OC) can damage the hardware

I've based my reply above on this post.
It is a much longer version of what I summarised earlier.
And, sorry, even UC/UV can damage your hardware in rare situations.
It does baffle me why people spend so much time tweaking things as you mention when the net returns are negligible, and often cancelled out.
So to sum all this up. We just have to leave the CPU & voltage tables alone since it damages hardware?
Via the Internet
It's not that you have to, but that chip designer recommends it.
