[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
I have been reading a few things about the Hd CPU and i know that it can handle this speeds, atleast just for the sake of a few benchmarks. As somebody would see in Z/G2 section there is alot of kernel work @ 1.8,

So the 1 million dollars question is:

Why isn't there such a kernel for our beloved Desire Hd?

[Desire HD Q&A, Help & Troubleshooting] LeeDroid:
A device this expensive! I personally wouldn't run the risk of killing my processor

[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
So how come Z is handling up to almost 2Ghz? I know that the voltage would be high, but ad high as frying the cpu? Even using failsafe from setcpu? How much above 1.51 should the voltage be increased to handle it?

Sent from my LeeDroided Desire HD:-)
[Desire HD Q&A, Help & Troubleshooting] jkoljo:
The voltage has to be ramped up quite a bit. Usually when processors near their limits of frequency, voltage has to be pushed much to get little more frequency.
[Desire HD Q&A, Help & Troubleshooting] :
There are such kernels, but not released to public.

I wouldnt mind testing one on CM7 though :).
[Desire HD Q&A, Help & Troubleshooting] Aamir.Badat:
i wouldnt mined to aslong as there is a proven stable kernel at 1.8Ghz ;-)
[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
Where? I might give it a try, as i said just for the sake of benchmarks. It is sad to se a cheaper device such as Z/G2 to best the crap out of HD in linpack.

[Desire HD Q&A, Help & Troubleshooting] BootloopedMillennials:
Dont know why its sad to see. At similar clock speeds, both the Z/G2 and Desire HD are gonna score in basically the same range. They have the same gpu and basically the same cpu (cpu in the G2 is an underclocked version of the Desire HD/MT4G cpu).
[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
It is not the same desire z is msm 7230 if im not mistaken and desire hd has an msm 8255. The GPU yes is the same. So the real score diff will be based of the cpu.

Τελικά όλοι οι έλληνες είμαστε τρελοί και γουστάρουμε! :D

Yeah,I too pray for such a kernel!Plus,if someone uses it,they aren't obliged to clock their CPUs @ 1.8 all the time.Lower frequencies are still there you know! ;)

WTF did this thing just do? :confused:

Anyway,managed to read it and I've been thinking the same!Plus,isn't that feeling that it's fast awesome?Something like having a 50cc motorbike and making it 90cc! :D
[Desire HD Q&A, Help & Troubleshooting] BootloopedMillennials:
Thats why I said basically similar. The only main difference is one comes out of the box at 1ghz and the other at 800mhz. You clock the G2 to 1ghz Im pretty sure it will score in the same range as the Desire HD. I still think the msm 8255 is an overclocked version of the ms 7230 and they will score similar at the same clock speed. Desire HD might and I say might have a bit of advantage cause of the extra RAM.

Heres a link from the manufacturer page, notice the differences:

[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
Even if they are the same with no diff at all, that is ine more reason to say that it is sad that we do not have a very high performance kernel of our own.

yeah. it seems that there isn't any interest on making this beast fly.
[Desire HD Q&A, Help & Troubleshooting] liljom:
:D

it's funny

I think there is no rational reason to make such a high speed kernel

You wanna be the man, would it be the only reason? I think a dev should do it for you and you can try it if it burns your processor :D

You just request and request, and ask if there is any interest.

You are adults, so go and look around how is it possible to change it, and burn your devices at 1800, 2500 or any MHz ; )

I'm just thinking what will you do with it, when you have it... because the device is smooth already, any game runs nice, with 1.72 based ROMs, there's no lag...

So I imagine, that you have the kernel, and you can make fantastic high linpack and quadrant scores, and you run around and show it to people "Look, what a high linpack score!" lmao
[Desire HD Q&A, Help & Troubleshooting] :
Exactly what I want to do. I will show every and each of my neighbours living on the same street who's their daddy.
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Dude,did you see anyone around here being ironic or rude?Cause you are both!

So,to get this inside your narrow head:Not everyone is conservative on how they use their devices.Some,like me,mariosraptor and jkoljo,like seeing what's the limit of their devices.Not because we like seeing linpack go high,but because we like the feeling that it can do so much.Having a kernel that allows us to overclock as high as 2 GHz doesn't mean we'll be running it 24/7.We'll just run it once or twice,just for fun,and get back to what we were using.Some minutes on it can't do any damage now,can they?

No one will force you to flash it on your device.

And you could as well seize insulting people personally when you don't know what they want or represent.We just "said out loud" our opinion for everyone to hear.If there is demand by more people it might as well be done.Or it might not.I am no developer,but if I was I would have done it a long time now,believe me!

I think an apology is due here.Some people that showed interest in this are much more respected than you and me combined.

With kind regards,

Apostolis

PS:I'm no adult man,I'm 16! :D
[Desire HD Q&A, Help & Troubleshooting] liljom:
I understand.

We have this wonderful device here. I think people bought it, because they know it's fantastic.

I can understand people who want some tuning.

But I think a lot more people should learn developing.

These people are smart, who request this kernel. I'm sure they could do it by themselves : )

Only thing I really don't agree is to ask developers, and I felt like they were bitter, because they didn't get answer in a few hours from any developer.

Let's go guys! You can do it by yourselves ; )

[Desire HD Q&A, Help & Troubleshooting] smog:
Lee I was trying to do it by myself just for fun. just for try. I've set up a virtual ubuntu machine and prepared all the environment, I've downloaded latest sources from buzz git and modified the acpu_freq_tbl array in acpuclock-7x30.c to reach 1,8 Ghz. I've built my new zImage and flashed it to the phone (just the zImage since I am already on latest buzz kernel) but I always get very poor quadrant benchmark and wifi is not working. I can see and pick the higher frequencies in setCpu but I feel the overclock is not really applied... what am I doing wrong ?

Please help

P.S.:

I add the following elements to the array:

{ 1632000, PLL_2, 3, 0, 192000, 1275, VDD_RAW(1275) },

{ 1728000, PLL_2, 3, 0, 192000, 1300, VDD_RAW(1300) },

{ 1804800, PLL_2, 3, 0, 192000, 1300, VDD_RAW(1300) },

{ 1824000, PLL_2, 3, 0, 192000, 1325, VDD_RAW(1325) },

and modified the cpufreq_frequency_table freq_table array accordingly

Well,sorry for probably saying too much,but I was frustrated seeing your post.

Well,I do understand everything I should about programming,but high school in Greece doesn't leave me enough time to learn some programming.Unfortunately... :(

Two years from now you'll be seeing development from my side for sure! :p

Anyway,we asked devs because they already have their kernels ready.For them it's as easy as adjusting some numbers.Just because of that. :)

Well,why don't you make it 2 GHz? :D

Seriously though,it's all or nothing!My opinion?2,the end.

You have clarified you accept no responsibility,so what users do in their end is their responsibility alone. :)

[Desire HD Q&A, Help & Troubleshooting] Jacob1369:
Did you disable perflock from setCPU?
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Might be perflock if it's directly from the HTC sources.

But beware that the voltages are a little low and it may crash.Apache,for instance,used 1250mV @1516 MHz and crashes were frequent for some(Not me luckily! :D ).I think upping every frequency's vdd levels by,say,25mV will be ok. :)

PS:The developers who made the G2 2GHz kernel used 1500 mV I think.Dunno if it was also the case with 1.8GHz...
[Desire HD Q&A, Help & Troubleshooting] Jacob1369:
I use the OC method from this old post:

http://xdaforums.com/showthread.php?t=815808

And test speeds by changing values via GCScript:

pll2_l_val=78 vdd_mv=1000 vdd_raw=234 = 1497MHz

- Fast but stable for a few days, maybe 4 or 5 before needing to restart or DHD will freeze while processing multiple tasks. Seems to hang with Sense UI but not on Launcher pro.

pll2_l_val=79 vdd_mv=1000 vdd_raw=234 = 15++MHz

- Extremely fast but very unstable. I got tired with battery pulls especially using an Otterbox...

pll2_l_val=77 vdd_mv=1000 vdd_raw=234 = 1459MHz

- Daily driver. I just use the 1497 settings to show off with my friends that are on SGS and iP4... :p

1.8 or even 2 is definitely possible. I agree with a DIY-kernel and if there's no time to learn how to create one, just wait till its released... :D
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Well,that's known to be a not-so-stable mod,but it would do the trick once...! :rolleyes:

Anyway,with that I couldn't even manage 1.4 GHz.When the frequencies are built into the kernel we can talk ok! :D

And give the other guys something to admire! :D
[Desire HD Q&A, Help & Troubleshooting] Jacob1369:
Yeah, I'm actually holding off till a better built-in solution arrives (I do mean better than what's currently available). I've tried custom OC-able ROMs but wasn't satisfied and I figured I'd stick to this trick since it works just fine for my needs. It won't be applied every restart but makes it safer that way... :D

(Edited: 1459 is the daily driver... not 1479)
[Desire HD Q&A, Help & Troubleshooting] smog:
Noway! Kernel is not perflocked checked into .config (I took it from 1.2.2 buzz kernel) and with setcpu. I can see the clock is set correctly to 1,8 Ghz but I always score the same as 1,5Ghz in quadrant (slightly more than 2500). Maybe there is some other thing to change in the sources. Any hint is appriciated
[Desire HD Q&A, Help & Troubleshooting] mariosraptor:
hi everybody. i can see that there are alot of posts. i started the thread cause i was dissapointed that the DHD had no kernels such as the Z. a kernel like this for us that want to try it is offcourse crazy to use 24/7 so if one accepts to use it(that includes me and as i see some more fellows) it would be as i have stated for the sake of benchmarks and why not to show off, doesn't matter that i am an adult and some more the only thing that does matter is that we have a great device and we want to maximize its abbilities.

i feel like tuning my car. so to conclude, if could make it myself i would have done it already, but work and girlfriend and alot of training do not leave me much of free time to compile a kernel of my own. so to those who can(i do not like to beg), if you can please compile it.:D

this is a custom kernel with possibility to adjust maximum frequency, so you can test the boundaries of your device.

its not a good idea to have kernel with hardcoded frequencies above 1,5GHz, because every device is different and what is stable on one, need not be stable on another...

Anyway,it gets better results because for the Desire Z the frequency values are hardcoded into the kernel,while with kamma's kernel we only alter the max frequency through a script.Awesome work kamma,but if someone(fingers point Lee here? :D )can make a kernel with the values hardcoded up to 2 GHz?

And can someone please explain why the GPU can't be overclocked?Thanks! :)
[Desire HD Q&A, Help & Troubleshooting] kamma:
this is nonsense.

1. The method, you set max freq with my kernel is the same as if its hardcoded.

2. If anyone make kernel with hardcoded freq, whats the right voltage, to suite most of users?
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Woah,chill out dude!Nothing is wrong with your work and we appreciate and admire it.I just tend to believe that setting really high frequencies makes the frequency "jump" too much.Going from 1450MHz to 1750 leaves a 300MHz "gap" which possibly has an impact on performance.

I might as well be wrong,but we can only try and see! :-)
[Desire HD Q&A, Help & Troubleshooting] kamma:
i am calm. i tried to explain it.

if you just use the OC for benchmarking, there is no problem with a gap, because you should switch to performance governor, which gives the max performance/frequency but for serious usage it could be problem.
