Hi
Is there an area on the xda2s where you can maximise your processor speed? On my old Dell x3 you could choose 'max perfromance' or 'conserve battery' etc.
It's just for a 400mhz product it gets quite slow sometimes..........
Apologies if this has already been asked....I did search for it but couldn't find anything...
Thanks in advance,
HPJ

Your right for a 400Mhz it's sometimes slow ... d'ont understand it ...
My previous device was a 400Mhz aswell, and was much faster.
Maybe it has something to do because it has a build-in phone?
Have you tried
http://www.handango.com/PlatformPro...4§ionId=3287&catalog=30&topSectionId=3274
won't it damage the cpu of our pda?.
regards
Not if you dont push it too far! It defaults to 472MHz max, you can switch off this limit and take it further. Mine is stable at 472MHz, never tried to take it further. Overclocking generally wont damage the CPU unless you are daft. As a rule, the PDA will just crash if you take the clock speed too far. The crash may mean a hard reset if you are unlucky!
In short you can kill the proc through overclocking, but its unlikely.
One point to note is that the 'auto scale with cpu load' option on xcpuscaler is a load of [email protected] Does not seem to work at all.
I mainly use xcpuscaler to slow down my proc to 200MHz, dont need 400 MHz to read avantgo or an ebook, or listen to an MP3, but running at 200MHz does give a reasonable increase in battery life.

I have installed the xcpus..., do I configure it so that it varies the speed automatically, but is it always constant to 400 mhz??
does somebody know because??
thank you
XCPU2.85
Anyone has a copy of XCPU2.85 which is not trial version. Mine has expired.
2.82 does not work in 2nd edition.
Try using Pocket Hack Master from Anrom Tomov. Runs good on the QTEK 9090. See www.handango.com
A little note
Dunno if any of you realize this but be careful should you decide to remove pocket hack master..
i noticed that it does not clear the registry of its CPU settings... i found this out by uninstalling the software (after setting cpu speed to 472)... and when i reinstalled it again.. the software defaulted to 472 mhz..
make sure you go to the registry to get rid of some of the settings... just do a registry search for anton and remove the reg entries..
sorry if you guys already know this.. and i don't know if left behind registry keys mean anything if the software is not active but better be safe than sorry right? and i'm a noob here so just trying to help out
Hey guys this is how overclocking is working on Blackstone, on ac or battery power. Stable at 672 MHz. and the phone is that much more snappier.
Install NetRippers Msm7kCpuSpeed V.2 App. in your Device.
Install oruam57s SetCpuSpeed v1.0d on SD card.
Take SD card out and soft reset the phone.
Open registry.
Go to HKLM\Software\Msm7kCpuSpeed.
Edit the values as below:
BootTime = 90000 (This is important. This value gives enough time for the
phone to fully boot up. The phone has to fully boot up
before the OC kicks in)
CheckTime = 20 (Stable at 20, otherwise yoyos between base and OCed
cpu speed)
Command = 0
PerfomanceLevel = 35 (This speed is stable for me without SOD)
ScreenOffPerfomanceLevel = 27
SettlingTime = 10
Close Registry editor, insert SD card in the phone and soft reset the phone.
Once the phone has fully boot up, give it a minute before opening NetRippers Msm7kCpuSpeed and you should see your OCed cpu speed.
If your OC cpu speed isnt stable then take your SD card out,soft reset the phone and registry edit PerfomanceLevel to a lower value.
To restore back to phone default speed:
Open File Explorer.
Go to Windows\Startup folder and delete SetCpuSpeed.
Soft reset the phone and phone default speed will be restored.
Before deleting SetCpuSpeed from Windows\Startup folder , save it in Documents folder so if you want to overclock again, copy and paste it from Documents folder to Windows\Startup folder.
SKTools Benchmark at 672 MHz:
Intiger = 416.5933 Moves/25 usec.(At stock speed Intiger = 332.6351)
Floating point = 9.56 MWIPS. (At stock speed Floating point = 7.47 MWIPS)
I haven't tested it but this should also work on SEX1 and Touch Diamond.
OVERCLOCK AT YOUR OWN RISK.
After install by follow the instruction, my HD work perfectly. And I try to set speed up to 710 Mhz (Level 37) then it hang. So, the stable should be 672 Mhz on battery as above. THK
.
sorry, but i haven't found the link to download SetCpuSpeed v1.0d on SD card? and this works with the original rom ?
by the way, nice work!!!!!!
Battery performance?
How is the battery performance compared to stock speed? I'm gonna try myself anyway but i dont have time now... Just curious

This is good Post but why you didnt provide a corect link for the apps you need SetCpuSpeed 1.0d cab : http://forum.xda-developers.com/showpost.php?p=7426966&postcount=1000
Where to install NetRippers Msm7kCpuSpeed in Storage Card or?
Also Hatori create a cab with the reg setting you need to do so if all is working corectly you can include them i mean to edit the post to be more simple and clear and easy to use
Thanks
I cannot understand what u mean by without having gps? so when we overclock we cant use the GPS of the phone or what?
My results are :
SKTools Benchmark at 672 MHz
Integer 420.1011
Floating point 9.633
Note when i do the Bench i forgot ON my WiFi but the result is still GOOD and i can see faster UI and everything.
Also my question is if i want to go back to default what i should do? step by step.
1st to take out the SD card and reset the phone, then edit the regs back to default and uninstall the Msm7CpuSpeed from the phone, then softreset and after the phone load inser in the SD card then uninstall the SetCpuSpeed 1.0d cab and again soft reset.. is that corect? and after a reset the phone will be back to default settings?!
Thanks in advance
I've been follow the original thread.
Qzytor found a solution for the "Blackstone" users, how to overclock our devices without SOD.
Thanx to him my Blackstone flys now
I've tried running it on my blackstone and it hangs on 672MHz, mine only runs stable at 652MHz (level 34)
I am running an NRGZ ROM though and not blackstonehenge...so that might make a difference.
Very awesome!!! My Blackstone now runs stable at 691,2 MHz (level 36) and it seems to have no (or minimal) affect to battery life! I can finally play Spyro using fpsece at 30fps and Abe's Exoddus at 45fps. Very nice

if you were following the original thread, then you would have known that, originally, having the gps enabled was one way of preventing the device from locking up when overclocked.

Previously (before Msm7CpuSpeed registry value edits) overclocking only worked if gps or wifi was on.
Yes Gps works while the phone is OCed.
For reverting back to phone default speed and where to install NetRippers Msm7kCpuSpeed, see post 1.
OCed my Blackstone only to 652MHz (only one that was stable for me =/
No benefit from the "OC" as far as I can see..
...although others might be more lucky
I was very lucky and easy Overclock my Blackstone with no Problem and the device is just fly but i notice the side effect of this Overclock the Battery DRAIN is alottttttt
Normaly with the ROM im using with one charge i have around 3-4 days Battery so i Overclocked today and when i do it i was on 47% of my battery and 5 hrs latter with litle usage i mean few phone calls etc i was on 10% of my battery very very fast
So i guess if you want to use the Overclock you need to recharge your device very often like everyday or every 12 hrs if you use it alot i prefer to have 3-4 days power and for this reason i just revert back to the default processor speed for now

You're right, worked for me as well but kinda batter drainer, have to recharge every day...
I bought my Blackstone a month or so after it was released, so it may have a lower quality CPU or something..but I can't overclock much at all, so people with performance benefits - be happy!
...I am normally charging everyday anyway, so I don't really mind =]

Dude i bought my HD exactly when was released and i wait few days like week the device to arrive in my Country so i think your problem is not becuase like you think your chip is "old" mine is older and i still can Overclock without problem
anyone know who OCed can tell me how the HD performance playing in RMVB file?
before it, i can play but kinda laggy, if the OC work for better performance, shud really gona try it~

When I was running Energy ROMs I couldn't overclock, I got some freezes or the device just restarted... and I think that's because Energy ROMs for Blackstone are kinda slow and resource demanding.
I'm now on blackSTONEhenge™ HyPer v2.5 (6.5.3.24623) and I have to say that this is the fastest Sense 2.5 ROM I've ever tried, overclocked it to 672 and works well but you have to wait for 1 minute after sense loads every time you restart or else it will freeze. If you are a heavy duty user and you say that you recharge your phone every day, I think the battery won't last 24 hours overclocked.
Hey Guys, what about heat? Cuz if I put Android i can tell that the device is kinda overheated even when is in sleep mode. So is there noticeable temperature changes when we overclock our BS with this?

Yes it it but not as in Android when it almost melts.
You can see that it's heating up but not as if you can't use it...

Hi!, i recently flashed my Arc (that is an prototype, a very complete prototype) to an official firmware (2.3.3).
But i have some problems, like i can't make a "factory restore" because i got a blue screen saying "aww snap ...."..
I can't unlock the bootloader, because i has tried with my code generated on SE website and i get an error message.
gingerbreak doesn't works
Super One click Doesn't works
I just can root downgrading to 2.3.2 , but when i do the update, the phone crashes with a blue screen dumping (that takes 10 minutes on finish).
I think that i never can root my xperia arc .
(if someone haves a solution please tell me )
oh yes, the question..
I have runned a benchmark tool(Quadrant Standard) and in the system info i get this CPU values:
Current freq 1024 MHz
Max freq 1024 Mhz
Min freq 122.88.
If my cpu is running on the maximum performance, that's not good for my battery life, and i can imagine that i can't down the clock if i don't root the device.
I have the same max freq. as you so it should not be overclocked and I'm not having any battery life issues.
Are you having battery life issues?
hmm nope, the battery life is about 2 or 3 days depending of the use.
The CPU clocks up as and when needed (this is called scaling), mainly it should drop to around 256mHz (i think) when not in use ad jump up to the maximum if its required, if it is at 1024 all the time it may be that there is something running ie an app that is forcing the CPU to stay up at that speed.
easy way to check cpu activity : ''cpu spy'' from market simple and does what you want
Need help or advice , last week i've been using lollipop rom, im not familiar to the new settings and setups on this so i explore and try the kernel settings. I set my kernel setting to maximum, like cpu which is about 1750 mhz all cores and gpu 450 thermal off etc. Because i hve been seen some comment that the lollipop rom reaches to about 27000 k antutu score . i tried it by my settings which is my phone crashed while testing it to about 25% of testing. Now i just go back to sling rom and try again to test with no modification with the kernel or any optimizing the performance and im surprise that it crashed too and tested with putting my phone on the freezer which i guess im having phone temperature problem but it crashed too. Now while charging and testing in the same time it completes the benchmarking of my phone.
I guess my battery is the reason my phone is crashing when on the heavy load of using
Or some hardware issues? Like cpu,gpu ??
Sorryto my bad english and explanation. Thanks

See this thread and check you PVS value of CPU....
http://forum.xda-developers.com/nexus-4/general/poll-cpu-binning-t2052496
If you are getting slower or slow PVS, try to increase the voltage of 1750mhz freq and run the benchmark...
Hope it helps

Thank you . the result of my PVS is 4. I also suspect that i have low voltage to run the processor thats why when im doing benchmark it shutdown even playing COC.
How can i change my voltage and what is the default voltage ? Thank you again.

trickster mod or faux clock app...
I got really annoying problem here...is anyone check this or never encounter the problem i faced...it seems i cant get the most out of my mi max when needed...when playing games and watch 1080p video, small core stuck at 1017mhz and big cores stuck at 1190mhz..ive change it several times but nothing happened...because of this i got stuttering when playing video and games....ive check the temp throttle, and dissable all of it...but the problem still persist...ive test it with miui globerom and mm rr....same problem with both rom...
how can i get small cores to min 400mhz, max 1401mhz and big cores 400mhz, max 1804mhz when i needed it...
Here some sample image when im playing games and watching 1080p video.

And also my big and small cores setting...i dont fiddle with anything on it..
As much as I see your cores do reach peek clock frequencies I also see a lot of bad configured tunables in interactive governor setup you are using especially timer rates.
Don't have much time now to explain or adjust it me by later today. & I don't know from where you got your config as it have CPU frequencies that are not supported by S65x SoC's so plenty of problems there to start with.

It reaches peak at normal usage from time to time but when playing games oland watching videos, the cores stuck at 1017mhz for small cores and 1190mhz for big cores...small cores max have 1401mhz and big got 1804mhz...so there s a difference in performance when in trottle down like that...ive ask some other users....but they also have the same config as mine...this is the stock config for globerom and ive never change it....
If you can give a screenshots of your config, i would be glad to test it if it work on my device...
Sorry the first 2 pictures doesn't show clearly...

I dont know what stock setting config are...this is the setting i got when flashing the rom....so probably its the roms fault?...or maybe some mode causing this....if i flash the rom again, maybe it will be fixed...?
Can i get any example setting for me to fix it...
Put;
Above high speed delay

40000
Hi speed freq
900000
Target loads
90 600000:95 900000:97 1100000:97
(delate other entries in target loads)
Timer slack 40000
For the big cluster do it like this:
Above high speed delay
40000 1382400:60000
Go high speed load
90

Should be much more snapper, balanced, power aware with a good performance.
Don't charge anything else & in a couple of days tell me how you feel about it.
Have to add that used Interactive is rather old & doesn't have some tunables.
Best regards.
And one more thing...is it advisable to use L speed to improve the cpu load....or might it interfere with the manual setting...

My advice is that you don't use anything that you can not check in code what exactly it's doing. L speed shifted away from using scripts long ago so I don't recommend using it.
Edit:
You can try HEBF if you wish it still uses scripts.

Ive also checked that i cant change the governor either...it stuck at interactive....this things occur if the battery and cpu heats up to 38-40°....at 40°, all cores is lock away from any setting...ive tried to diactivate all the temperature throttle...but its the same...no effect...still lock....then if the rom is the culprit, then ive used RR rom and Miui GlobeRom...2 of a different Rom all together...still persist this problem...so im stuck to dont know what to do rather than flash unmodified stock rom and see whats happened...

First of all all monitoring apps aren't real-time secondly they some times have the problem with displaying correct informations for 2,3,4th cores on the big cluster (I don't know why) falls displaying how they don't work but believe me they do. Tried to do a bit of monitoring my self & depending of game & or video player the cpu utilisation varies but little cores do meet their max frequency when needed & big ones do stay around 1200MHz when used but if you ask me that is perfectly normal & desired actually if it whose otherwise you would got thermal throttling. So this doesn't have to do anything with thermals nor CPU governor, it's probably imposed by the cpu ctr driver. I don't know where you got idea how any of this is crucial for either gaming or (good forgive) video playback; for GPU its crucial that one of CPU clusters (or with hot plug at least one core) scale along as it determines the RAM frequency, on the other hand video decoding (for supported formats) it's done on a DSP so it's desirable to CPU's actually stay as much as they can on active idle frequencies (periodically syncing system tasks) if you use unsupported video compression or for some other case choose to use software video decoder then CPU's jump to full frequency as they get utilised.

For monitoring real time cores, i go to development option and select Show cpu usage option....that i think doesn't lie....the problem im facing is that why doest the cores doesn't stick to selected frequency....ive never seen it do that on other phone before...even when the phone heats or overclock...theres always for us to change it manually if we want to..so for my case, its not like that...it persistently selected what it want...
The problem im facing is in fact a video playback...Hevc x265 1080p 24fps.....so if your aware, hevc is a new encoder for video playback with lower size but better quality...but to run it, it needed more processing power...ive tried with same format but with 720p only...it runs flawlessly...so i assume 1080p will do the same....but in this case...its not....yes the video only support software decoding...and i used mx player for it...since it support it, ive set it to run at max performance....to run all cores to play video...
Ive run the video at 34° battery and cpu...small cores run max clock...and also 2 big cores run max 1800mhz....the video runs smoothly...until the temp reaches 37° the big cores start to slow down to 1600mhz....then after a while 39° 1190mhz....then the video start stuttering badly until in unwatchable....
So this behavior of big+small cores is for me kinda unnatural or is it, it supposed to be acting like that...i dont know...this is the first cluster core phone i ever used...so if it supposed to be acting like that, then are we getting the most out of the phone performance if it always dumb down like that...
Monitoring does lie (check by running Volumark bench when it happens) & that temperature/frequency down scaling is not normal behaviour.
I do know what H265 is (& even how it works) I also know both hardware (QC) and software (Google) libs on firmware are broken for it (surprisingly Vp9 just works fine). I still think how H265 full profile FHD culd be a little to much for a CPU alone.

That's why im scratching my head all this time...ok ill do some research more and post if anything new or if im able to solve it...thanks for the knowledge...
Just for curiosity...i ran Volumark at cool temp 32° and all cores run well....got 72 at Volumark.
But i run again with temp 38° and my cores, like i said earlier, big cores max at 1200mhz and the other one offline...got 39 at Volumark.

As I told you that isn't normal behaviour. I would re flash firmware or better yet if you have a full backup in recovery if I whose you.
This is my logcat...if someone have some free time or care to help me solve my problem, care to take a look...
Im hoping someone could provide me an answer for me to fix my problem im having...i dont think i can live with a phone that behave like this...
Im not able to read it and hoping someone can...just post it here.
I take this log out from kernel audiutor...so i hope thats ok..

Uffff. Log didn't show much at least not reasonable to me. There are cuple of IO denials at the end. Did look last cuple of pages. It's really hard to get to the bottom of this, actually impossible regarding how much potential problematic things you are using, from xposed framework to the fact that you are on beta MiUI relase to the fact you used various tuning apps that changed the behaviour. Sorry but I cant really help you. If this persist after flashing full official stable firmware freshly then try to catch the fresh logcat right afterwards down frequency cpu happens along with screanshots, post it hire and fail the official bug report at MiUI forums (with a screanshots & logcat attached).
Best regards.

Well, i did a fresh install but using latest Official dev Rom, did not touch nothing or change anything on the rom after install...just install couple of apps and do the test....but unfortunately, the problem still there....
Here are the fresh log cat, if your wanna take a look and feedback...this is the last time i think...i will try to contact post it on Miui forum as well.
