Can someone say to me to how much can be the htc mytouch slide can be overclocked
it really depends on the quality of your chip, some people can overclock well above 825, some can only go up to the high 700s. but usually a good place would be low 825 and high 700, that seems to be the stable range for most slides.
825 is average. Some units go up to 864 stable. Mine is on 844 stable with Miguel's kernel and 825 with CM stock .

i am running cm7 with stock kernal i go into settings then to cyanogen settings then to cpu settings the min. i can do is 245 mhz and max i can do is 1113mhz and it was set to 998 mhz what would be a good setting to set the max at for better battery if able and also not have bad performance?
all of the options are:
245 mhz
384 mhz
422 mhz
460 mhz
499 mhz
537 mhz
576 mhz
614 mhz
652 mhz
691 mhz
729 mhz
768 mhz
806 mhz
844 mhz
883 mhz
921 mhz
960 mhz
998 mhz
1036 mhz
1075 mhz
1113 mhz
I would just leave it at 998. You really don't notice that much of an extra boost by overclocking IMO. You can underclock, I had mine at 768 and didn't notice any slowdown, but can't say it helped battery life tremendously. Try out what you want and take note of your findings. See what combination works best for you.
Defaults are actually pretty good. However if you want to increase your battery life look at some of the other kernels out there. I've choosen Chad's incredikernel. It charges up very fast and has a min CPU of 128 which improves the battery life when the screen is off.

yeah i have the incredikernal on my computer ready to put on my SD card cause ive seen pretty much everything good about that one but then i also see everyone saying that kernals dont really show a difference.. i guess my only option to do is try it out and see where it takes me...

thanks for the reply and yes thats what im going to do
the latest one from cm7 gives me a great battery life
+1 for Chads.
anything with the smartass gov. rocks imo.
Are there any bad things that can pop out if phone is OCed to 768MHz? Does it last shorter, can it screw battery etc..?
Thanks
It's unlikely you will 'pop out' something at 768 MHz. Some Wildfire's will not be stable at that speed, and, that is about the worst it can get, in which case, your Wildfire will lag a lot,and you will have to tone down the frequency a bit.
Battery life may take a hit, but, it wont be anything drastic again, also, as for component life, again, it may take a hit, but, even at 768, it will last till the time you are ready to retire it.
what is the recommended overclock speed, i can overclock to 729mhz and its stable no reboots etc or should i overclock to 691mhz??
Not really necessary, if your phone is not behaving abnormally at 729.
Is the difference with overclocking really that noticeable compared to stock speeds?
It's marginal. Definitely not as much as the overclock %age suggests. The only big difference will be in benchmarks.

i just overclocked to 729MHZ its awesome, the speed is noticable , and its stable i hope its fine and doesn't take more battery life lol
got mine at 710mhz and its stable no problems at all
keep the max overclock value at 729 MHz and the minimum on at least 264 MHz.
This saves battery when phone isn't in use and the speed increase is noticeable, it's rather nippy! (certainly for texting anyway)

Device: HTC Wildfire, 16GB Kingston micro SD
ROM: CM7
Recovery: CWM
Status: Overclocked @ 726 MHz - stable
This thread should be a talk about the lowest possible voltage-levels which are well-known to be stable.
Background:
I'm using a Custom-ROM on my 'classic' Desire.
Nearly every Custom-ROM has a specialized Linux-kernel with "OCUV"-Feature.
(For those, who don't know what this means: OverClock/UnderVoltage )
With OC you can speed-up you Device.
Normally, the Desire has a maximum CPU-Clock of 998 MHz.
Most custom kernels offer an OC up to 1'113 MHz (+11%), some even go up to 1'190 Mhz (+19%).
The UV-Feature enables you to reduce the voltage of the CPU.
So you can save battery (longer stand-by)
or 'protect' your CPU from getting too hot while using CPU-intensive Apps or using Overclocking.
The HTC-Desire-CPU can work with these discrete CPU-clocks (MHz):
Official: 128,245,384,422,460,499,537,576,614,652,691,729,768,806,844,883,921,960,998
Overclocked: 1036,1075,1113 (or even more...)
The concrete CPU-Clock is chosen by a so called CPU-governor, according to the current requirements:
Normally, when the screen is turned of, then the CPU-clock is limited to 245 MHz. Even if your screen is on but you do nothing that looking on a steady-home-screen, your CPU-clock will be low. But when you do somthing (starting an App, playing a game...), then your CPU-clock wile rise (more or less quickly) up to the maximum-clock and will fall down again when your devices idles again.
Additionally there is a table which defines the conrete CPU-voltage-level for every single CPU-clock-speed. There are factory-default-values for this table (see table below). With the UV-Feature (Undervoltage) you can change this table, normally to lower voltage-levels (there is no need to increase the voltage).
But there are limits for UV: If the voltage for a specific CPU-clock drops under a CPU-model-specific value, then the CPU makes sudden calculation-errors and the software (your App or the whole Android-OS) get's unstable and crashes and you have to reboot yout phone.
Perhaps you even have to remove the battery because the device doesn't react on your Power-Button-Presses any more.
But: A (permanent) defect to your hardware is unlikely.
To start-over i present the result of some intensive tests i made with my device:
Code:
MHz Default(mV) Still-ok(mV) CRASH(mV)
128 975 825 800 (thx to rootSU)
245 1000 850 825
384 1025 850 825
422 1050 850 825
460 1050 875 (not yet tested)
499 1075 900 875
537 1075 925 (not yet tested)
576 1100 950 925
614 1100 950 (not yet tested)
652 1125 975 950
691 1150 1000 (not yet tested)
729 1175 1025 1000
768 1200 1025 (not yet tested)
806 1225 1050 1025
844 1250 1075 (not yet tested)
883 1275 1100 (not yet tested)
921 1275 1125 1100
960 1275 1150 (not yet tested)
998 1275 1175 1150
1036 1275 1200 (not yet tested)
1075 1275 1225 (not yet tested)
1113 1275 1225 1200
The voltages between my test-steps can easily be interpolated (for now).
To these 'min-but-still-ok-values' i added a 'stability-supplement' of 50mV and set up my device accordingly. I use the App "OC/UC Beater2" for this.
Now it's running for some days with no crashes. So far i can say: it's stable.
I would like to see other users to test these values and give a response here in this thread (dont's forget to add 50mV!!!!!).
Later (in a few days or weeks) i will suggest to reduce the table-values by 25mV and the cimmunity tests again.
Hope to get some responses. Thx.

This is ultra-extreme IMHO. I've not heard of anyone getting below 825 until now. I managed 850 for a while, but is happiest at 875

I haven't got any problems with 800, yet (I use it since june - so it should be stable )
Why don't you use a havs kernel - you could also lower the min mV to 800 for more frequencies and it's still stable because of the max mV (you can also decrease them)
PS: I'm using the vipermod

Motivated by your post i tested again with [email protected] - and you are right.
A little more intensive tests and my Desire crashed with this VDD-Level.
Perhaps it also has something to do with the CPU-Temerature.
Anyway - i will adjust the table in the first post accordingly and set the 'stable' VDD-Level to 825mv
Go on, community, such posts are what i hope to see

Hmm, i never tried a HAVS-Kernel.
But for now i want to stay at SVS for the next few weeks, simply to stabilize the table in Post#1.

I am using HAVS with AXI. 875-950 for 128, I dont need vipermod. init.d script works fine for me.
Mine PVT-3 was able to run with 875 mV on all official frequencies. Dunno if my "new" PVT-1 can do that as well.

Wow, that's far, far away from what i observed.
There is absolutly no chance to run on 875mV @998MHz.
Are you really sure about your setting?

Another poster claimed that a HAVS kernel will adaptively adjust the voltage based on both speed and temp. What I'm not clear on is how these voltages are set. Is the kernel using a table like the OP has, does it predict the stable voltage based on actual performance of the phone in use, or do I completely not understand?
I've seen a few 'I think...' explanations but nothing definitive.

Hi oli.henning,
Thanks for sharing those values, I'm noob in setting voltages and cpu frequencies and found your post very useful.
I've tried the still ok settings adding 25 mv for several days and everything was ok, now I reduce all settings -25mv, so ussing the still ok just as it is and working, no fc yet.
Thanks a lot man!
Hi there. I have a strange "issue" with my phone. Substantially, it looks like I have a chip capable of EXTREME undervolting. For example, gpu running @ 160 mhz and ONLY 700 mV. 533 mhz is @ 925 mV. It's pretty exaggerated in my opinion. I stress tested the gpu with all benchmarks and games that came in my mind at all steps. Same performance but huge undervolting. I am using Thunder Lite v3 and Neak kernel 2.02. I am currently, after 3 hours of messing with the gpu, dedicating myself to the cpu. I am now typing this with four cores active @ 1.6 ghz and, attention, 1000 mV. And there's still room for more...
It's too much in my opinion, so this may be a stupid question. Is this normal? Are there any powerful stress tests I may use? I am using multiple runs of Antutu at the moment. Is there a way I can verify the voltages I am applying are actually corresponding to what the cpu gets? It's too much in my opinion. I could have some huge luck, but I doubt.
Hey was wondering if anyone knows off by hand the lowest we can undervolt our phones @ stock freq or what our stock voltages are? I undervolted mine recently and got amazing results but stability seems to vary, using overclock freqs @ 1.89 running @ 1.087 mv 1.83 @ 1.05mv 1.78 @ 1.0375 1.7 @ 1.025 mv I seem to be fully stable pulling 28905 scores on anutu, my friends s4 isn't even this fast was very impressed phones not even hot at all, but I really want to try to tweak the lower freq to help with battery life/temp
solution to the battery drain problem
Overclocking the CPU frequency will lead to battery drain as u know it yourself....don't download any of the battery savers as they are useless .....try Greenify....bcoz it works....and it just is too awesome.....
Undervolted and got these results with anutu, impressive, looks like undervolting gets good results
Stock Speeds 1.7ghz -> 1.050
Barely over Stock 1.78ghz -> 1.075
Mild overclock 1.836ghz -> 1.0875
Higher overclock 1.89ghz -> 1.100 (highest anutu score)
Pushing it 1.944 ghz -> 1.250 (yielded a score the same as 1.89ghz)
what kernel were you using here and ROM? thanks
