Pro's & Con's of Overclocking - Defy General

I'm curious about how a phone's overclocking works.. Let's say the phone's default vsel/mhz = 57/800 . Would your phone's CPU heat up quicker if it was 57/900 ? Or it would still be the same temperature, meaning the life of the phone will be the same? P.S. I have setVsel and my vsel/mhz are
1. 22/470
2. 32/700
3. 42/900
It's been working fine for the whole day, and battery temps have usually been below 32C. But I have not ran a stability test for longer than 1 test LOL.

LOL, YOU NEED MORE VSEL...
the minimum voltage i recomend at 900mhz is 46 and 42 at 700 mhz...
AT 450 i dont know but i think 40 or 36 will be fine

Yeah you've got to test the individual phone and see how low you can go

How far can you push your defy?

As the title says whats the max o/c can you get out of your defy?
Im on standard 2.1 and can get 1300mhz @ 80vesl and get 1388 in quadrant.
So if your a o/c nutter and try an get the max out of everything tell us what ya can get!

I'm getting 1348 at the stock 800 mhz :/ Got about the same when overclocked. So, meh.
1350/80 stable, 1409 in quadrant. (stock rom)
Sent from my MB525 using XDA App
Pays ROM v5
Quadrant: 1405
setVsel: [email protected] (haven't tried higher than 1100Mhz yet)
I got 14xx (no trick) with 1000 @ 50 and 16xx (no trick) with 1200 @ 62 on finland 2.2.
For how long and how hot did your Defy get?
it ran for about an hour at 1350, and the max temprature was 39°C as i recall. based on abc's results, that jit in 2.2 is a big performance hit, looking forward to the official update

Just ran 1400mhz @ 95vsel
1508 on quadrant
Ran stability test for 2hrs30mins @28°c (had it sitting on an icepack haha)
Stock 2.1 and its very snappy.
Sent from my thumbs
just run [email protected]
quadrant 1709 1st score, 1671 2nd score.
2.2.1 froyo, 3.4.2-155
i got 1589 with 60/1200
Can running such high frequencies and vsels regularly damage the CPU? I'm kind of scared of toasting it, so i stopped at 1100/60 (scaled with setvsel)

i dont think so... did the stability test for around 15 minutes and the temp stays at 38 C
60/1200 with threshold at 80%, everything is so smooth

Hmm, i know have it at 62/1200, with threshold at 60%. 80% makes it feel a little laggy.
Hopefully the processor will last the life of the phone at these settings!

[Q] Safe Overclock

What is the highest MHz that i can go up to without risking my phone too much? My ROM and Kernal lets me go up to 1920 but thats probably not the best idea.

you have reason.... NO GOOD IDEA lol
in a kernel thread (a lot of time ago...) i was read... that was not recomended overclock avobe of 1600 Mhz... And atention important!!! don´t underclock down 170Mhz more or less (because can be the devece cannot exit from standby mode when you unlock the screen....) i cannot remember what was be the thread but i really believe that there is not a concret limit for overclock....
sure that it´s not good any tipe of overclock for improve the performance...
but i have a hero overclocked at 714 mhz (factory stock at 525 mhz) since 2009 and NO PROBLEM never,,,,
and my DHD overclocked at 1200 mhz (with a quality kernel in mode smartass)
and underclocked at 245 mhz more or less and no problem....
judge by your self but use the common sense... cheeeers
At the moment i have it on smartass to 1459 max and 230 min and it seems fine. Do i just judge it on the CPU temp, and if it stays quite low (Around 30c) then im fine?

it depends buddy...
maybe its well.... the normal temp. of my batt. in use is 33-35º (but here in spain we are now at 30º !)
but my question is... are you really sure about its neccesary overclock our DHD?
I think that still DHD supports well all kinds of software with 1 GHZ of power...
maybe for a future thinks....or for gamming but always u can overclock for use a game and then return to 1ghz...
it´s only a suggestion... maybe another OP uses the processor of different mode...
The overclocking limit differs from device to device, so there is no general answer.
As a rule of thumb, when you start getting random revolts or crashes, you have gone too far.
If you want a more professional way, just slowly turn the clock of your CPU up and run a stress test after each time. It takes a bit more time but should get you pretty good results.
How long should i leave the stress test running for?
The reason i want to overclock it a little is that it just runs a bit more smoothly with it over clocked a bit. Just everything in general seems a bit better to use, its not really for gaming etc.

CPU?

My phone has been freezing sometimes, and I think that maybe my phone isn't stable i have it at 600-28 800-38 1000-52 so what's wrong? How do I even use a stability test to check if it's okay?

There's a built-in link for Stability Test in SetVsel, you can download it from Market. Try to set 30vsel for 600MHz, and 40vsel for 800MHz, 28 and 38 was the stability limit for me. Maybe 52vsel should be increased to 55-58vsel.
Alrite, I put it at 30,40,& 58. The stability test ran the cpu 15 times in 25 min. How's that??
IMHO 52 vsel is definitely too low for 1000. I never get completely stable going below 55-56, I keep it at 58
52 is ok..i have 48 on 1000
my limits are [email protected], [email protected] and [email protected], these are stable. 28 for 600 and 38 for 800 is too low (at least for me). i dont think 52 for 1000 is too low.
that is just my experience. I have never tested below 55 on CM7 though, I have just assumed it to be too low since that was my conclusion with other roms. It would seem fine below the 55 mark but I would experience random unexplained freezes and reboots. I leave it on 58 now because it has seemed to cure the random problems.
Everyone's mileage will vary!
Thanks a lot, but are the results of my stability test alright?( 15 cpu runs in 25 min.)

Make sure to run the stability test at each frequency

Very Weird: SetVsel -> Quadrant Result depends on voltage (not clock) !!!)

Hi,
I got this very weird results from Quadrant:
@ standard voltage for 300/600/1000 I get 1450 points
@ 22/33/53 voltage for the same clock I get only 1100 points
=> so the performance is directly dependant on voltage, not clock! My system ran stable for days under all circumstances.
to be more precise: Only the voltage for Vsel3 (= 1000mhz in my case) is important
What does that mean ? Can someone explain ?
nope..thats now true..try to run the test again..i bet u will get comparable difference in score..
more vsel value does nor give more score..
processor needs some minimum amount of voltage(threshold) to run smoothly..once it crosses the minimum voltage the remaining voltage is the excess voltage..which doesnt affect the performance of the cpu..and excessive voltage produces heat which is not gud for the mobile
so do the test again or even lower the vsel value and test again..u will not get less score(if u get less score then do the test again and u may get more score).
btw pls correct me if i m wrong
I ran the test about 5 times with each setting.
@ 55 voltage I always get good results, below 54 I always get bad results.
strange...i have [email protected],[email protected],[email protected] get 2200+
btw i m running CM7
yeah I know that CM7 is very effective but I'm still afraid of the whole flashing process... And I don't know if CM7 can be returned to stock froyo if necessary...
I'm on nordic right now, which I flashed with RSDlite...
its very easy to flash CM7..just follow the tutorial..u should try CM7..it is awesome..
All the best

Undervolting??

Has anyone tried to undervolt his Note 8?
I'll be undervolting my N5110 soon...
So, am I the first one to it or what?
Please share your sets.
Here's my settings. I run CivZ ROM with built-in kernel
I messed with the same rom... yes I undervolted and overclocked and done as much as I could do. Went back to 4.2.2 stock and still get about the same performance, and battery life. One thing that I could not live without, is my 64gb SD card. Too many issues with FAT32 and my music and video files. EXFAT is the only way to go with 64gb SD cards. With my stock ROM, I get 8 to 10 percent every hour, and 15 percent every hour playing HD video through miracast to my TV.
I'm doing it right now, following this guide (not as closely as I should, most likely).
@Alastor_ru : how did you get your values? Mine are generally lower, besides the fact that Voltage Control allows 850 mV as a minimum.
Thanks, but what about the higher freq's voltages
I think that you have up to 1.9 GHZ or 1.8 at least
@bradipovsky, that's the same guide I will follow

I use SetCPU, it has 600mV as a minimum.
I perform several steps while set voltage to lower and lower values and stop to play with it, when I get my current settings. As I noticed, the biggest power eater is the screen, so undervaluing doesn't bring the big savings

I don't use the highest freq's, cause it's not needed for me. I limit the highest CPU freq to 1GHz.

Well, 8" of screen of course don't help the battery I'm doimg it mainly to limit the heating, so high frequencies are the most important. I think it's a better option than underclocking, but that's just my opinion.
I'll share my values later, but I don't think they're ideal yet.
