Why htc evo 3d is 1.2 ghz when the MSM8660 is 1.5 ghz natively?
And if i'll overclock it to 1.5 ghz the processor will have less life?
Thanks.
The 3vo is an overall less stable phone so if they set it any higher it might as well be a brick

every one of my current kernels run the cpu @ the qualcomm spec'ed speed by default
for the 3d, it is 1.51GHz
not 1 person has had an issue with this... and stability is solid
Its not uncommon for manufacturer to underclock processors for overall performance improvement and battery life.

They do it for stability and to keep heat down along with battery life in mind
Same goes for all CPU or video cards for the pc or laptops heat and stability . It's what ran best at the factory when it was designed .

You can do what you want man lol just the more you up the CPU the more battery it will use also if you don't do it right it can burn it up. So just be careful .

if you look at qualcomm`s website you will notice that they state that it is clocked at 1.5ghz. I have been running it and it reduces lag with minimal battery drain. because it was built to clock at 1.5ghz it will run at optimal efficiency at this speed. what causes instability is over and under volting.

I don't know where you get your info from about the 3VO being an already unstable phone to begin with, and setting it to manufacturer standards will only make the phone a "brick."
I really hope that was a troll post and not from a real 3VO owner.
Most ROMS you find, O/C to 1.5ghz anyway. Stability? Pffft.
mmmm.. i can't understand you. please write english a little better. Anyway if i'll set the cpu to 1.5ghz i don't ruin it right? It will not have a lesser life right? Because it's 1.5 ghz native.

Stock speed is what it was designed for . I wouldn't mess with things. You can if you want but whenever you bump the CPU up it does tend to use more battery among heat.

its rated for 1.5ghz -on the reference system-, if a builder make a system which dont follow reference board specifics it has to adjust something to make for it, in this case clock speed.
as generally builder are required to leave a lot of leeway in their specs you shouldnt have problems, just a processor a bit warmer than what specs require and which use more battery than for htc specs.
yet keep in mind that you arent using it as for -htc- specs (which supersedes the cpu maker) so you arent covered by warranty if something goes wrong.

I'm running my EVO at 1.5ghz for 2 months now, and I dont experience any of the mentioned issues, NO extra heat.(maybe because of the winter temperature ), NO battery drains.
Remember that there is a cpu governor which manages the cpu ghz as per the use demands.
Hope this will satisfy your concerns.

Lol I agree cause of the winter... Tho the kernel depends on who messed with it some folks tweak things and other can tweak it to run all the time at a certain speed which isn't good to do all the time..
ya i think HTC did it just to squeeze some more life out of these batteries.
Mmmm... Ok that's right. But you haven't answered to my question >.< Overclock to 1.5 Ghz will ruin the cpu?? Will have the cpu less life time?

how do you know? will you refound him if you are wrong?
dont just give false assurance if you cant put your money were you put your mouth..
1.2 ghz are what the hardware designer set as specs, anything else is a risk - minimal but still there is a chance that something will go wrong and if it happens its not covered by warranty as you are running the thing out of specs.
so its the owner choice, the risk its really small, nearly irrilevant but you cant tell him that there isnt any.

Honestly I forgot the exact amount my sgs ran at but I could UV it by like -125, -100, and -50 from slowest to fastest so -500 seems like a pretty extreme UV...its like 60-70% undervoltage...

I think you should go compare the values of other tegra 2 devices to see if it's common across tegra or specific to the atrix. That's first place to start.
But yes that is amazing that you got -500 mV stable.
PM me if you need some other tegra 2 repository links.
Would I get better speed if I disabled 1ghz frequency and left 1.2ghz the default Max frequency?
Would it be faster?
Or slower? Or nothing?
Don't like the 1ghz frequency. But I notice my phone is a little slower when disabling. It.

Good to see enyo has found where he belongs in xda. Asking questions and learning.
This is a big improvement enyo.
as to 1.2 feeling slower, your putting a massive undervolt on it. Try backing it off a bit and see if responsiveness comes back. Also, higher clock speeds can lead to better battery in theory by completing tasks faster and allowing the CPU to govern back down to a idle state.

Thanks. Your right. Backed to -75mV on 1.2ghz and faster response came back.
Also it because really fast after switching to the Medium Leakage.
I rarely let my phone sleep, so 1.2 is the maximum I'll go for speed/battery.
But, the more you UV, you get laggy if its too low, but stable?

I was running newts rls1 and getting 3600 quadrant and 6500+ antutu. When I switched to rls3 everything went down...so back to rls1 for me.
Other people have pointed out and I find this to work, that if you use setcpu and check "enable profiles", the 2nd core is turned on. I went ahead and set a screen off profile of 192/192 (max/min). I"m experimenting with these values, though. It seems I can knock down my mA use (per Battery Monitor Widget) by using the profile. The cpu does appear to be scaling properly. Many people have said not to use any of these cpu things and I did have some trouble with setcpu previously but it seems to be doing its thing with RLS1 anyway.

Programs probably just are't reading it right.
Speaking generally, the 2nd core will sit idle until needed, so it may be 'offline' when those apps check.
Until we get custom kernels/kernel source, there isn't much that can be done about it.

Lunatic summed it up perfectly. There are 2 cores, but the applications can't "see" them
http://forum.xda-developers.com/showthread.php?t=1496934 If you read through this thread the OP talks about the mpdecision not working properly. Basically it's the file that governs when both cores are on etc. It is something that can affect synthetic benches, but not real world performance. Probably why current ****s given by HTC = 0. Quadrant = trash and benches are for jerking off to numbers which generally is not an indicative to device performance. But whatever floats your boat I suppose .
Kool txs every1,,and I do use benchmarks to how my current Rom or tweak us working,,most of us are visual and need a program to tell us how it is..but I'm glad there s alot of hardcore peps to do the schooling
Perflock. There is no CPU management. Using setcpu doesn't do anything...its all in your head.

Well think about it, 4 cores consuming 1400 millivolts each.
Undervolt by 100 millivolts and you have saved the equivalent current of 400 millivolts (100 per core).
Thats close to a third of the total consumption of one stock core.
Sent from my GT-I9300 using xda premium
Undervolting is pointless unless you are planning on overclocking and want to reduce heat.
Battery savings from Undervolting are about 2-3%
This is insignificant and isn't worth the potential instabilities.
Plus it's not even a big consumer of power, The power the cpu uses is dwarfed by everything else in the phone.

The CPU is still the largest consumer of power unless you have extremely bright colours showing on the screen. Plus the phone can be undervolted very far below stock settings as it is, so savings should be more than what you quoted. For gaming I'd say my mali patch would bring quite some advantage in terms of power, since the CPU lock is gone and ASV scaling on the GPU can actually take place now, Netarchy already included that into Ninphetamin.

Somewhere on XDA I've been reading about some1 testing high (nearly max) voltages against as low as possible voltages (but if I remember correctly it has been a single core CPU). His result of this test was that even with such extreme voltage differences he was not able to save one percent of battery.
While I'm not too much into CPU voltages and undervolting I can't say anything about it for sure. But I'll be looking for that article...

I think I know what thread you are talking about and I completely disagree with those findings, at least on the S2 I did proper measurements myself with -100mV on various frequencies and the power advantage was almost equal to the CMOS power formula f*V² on full load applications. I advise people to stop comparing such articles from different architectures as the Snapdragons or the OMAPs as they have different types of power saving states which influence the measurements greatly. The Exynos is relatively "stupid" in terms of lower power states and relies heavily on DVFS scaling so voltage brings a greater effect on the dissipation.

Don't worry.
Undervolting is basically adjusting the voltages so the cpu uses less voltage aka electricity. It helps a little but it can make your phone unstable so watch out. Of you undervolt use the system tuner app on the market. You should definitely under clock if you want to save power too. When you undervolt be sure to underclock, and don't do it too low or your phone might freeze! That's why your shouldn't go so extreme on it.
Overvolting is basically adding more voltage to the cpu. There is no point in doing it for our amazes to be honest. It is already a battery hog. I guess it can help if you want to over clock a lot but there is absolutely no point in doing that.
In older legacy phones if you wanted to over clock because the cpu would be so weak, like 600mhz then you would have to overvolt to over clock to like 1ghz if you were lucky. Our devices are 1.5 ghz dual core and sense isn't THAT bad. There's no point in doing overvolt in this phone though.
PS, check out my rom in the development section.

I just saw it in Venom Tweaks and was curious. The most I underclock to is 1 GHz; cuts down the CPU maximum by a third and doesn't hinder performance to much. What voltage would you recommend at that clock speed?
P.S. I have I plan on flashing it to try it out when I get WiFi access. Trying to cut down data usage since I don't have WiFi at home.
