Is it possible to overclock the CPU to more than 1.5ghz? Most ROMs only go to 1.5.
I'm asking because the sensation xl has the same CPU but people are overclocking that to over 1.5 safely.
Virtuous Quattro ICS rom (and its kernel) goes to 1.9 safely
Is there a kernel that is compatible with sense 3.0 or 3.5 ROM?
i'm not sure, i dont use a sense rom

Yes. Endymion/Hyperion kernels allow up to 1.5Ghz.
Unity9 allows up to 2ghz. Its mot recommended however, as the kernel is old, and 2ghz isnt safe

It's not recommended. It's old and has bugs with the front camera.
In the first place, you shouldn't OC higher than 1.5ghz. The chip isn't designed to run a frequencies higher than 1.5ghz for ling periods of time. In the long run, you will damage to motherboard, fry the chip etc. Battery life will also be significantly shorter too.
If your intentions were to do that, i don't think you should have got this phone in the first place, and you should have just stuck with the Sensation.

the sensation xl is shipped at 1.5GHz. There's no need to exceed 1.2GHz in my opinion, at least not yet.

The Sensation has a dual core 8260 Snapdragon CPU, our has 8255 (single core) so i think that 1.5 Ghz for the DS is more than enough and safe, also reading somewhere that the 8255 is designed to run at 1.4 Ghz as an optimal freq and that the mobile manufacturers are free to undercloock/overclock for specific needs
I personally use the 8255 at 1.1 Ghz...never had lags
Hey,
I limited all my kernels, Hyperion, Endymion and Reaper kernels to around 1.5GHz, as it is way more than enough. I did this for some reasons:
- As it has been discussed all over these forums, devices handle OC/UV differently, no matter if the cpu is the same. This has to do with sheer luck with what part you get from the factory, your phone is only guaranteed to work at up to 1GHz. It may seem stable at 1.5 but reboot once a week, some phones may not boot at 1.2, and some phones can chug along happily at 2GHz.
- Every newbie that lands on these forums will instantly set the frequency as high as they can. Then they will get a freeze now and then. Then they pull the battery. Then they kill the phone. THEN they check the forums and read that they should not have pulled the battery.
- With my current roms, where the kernels are tested, there is no need for overclocking. Things run very very smooth at stock values. But I believe in "power to the user", that's why I even give the option to OC. The last time I had to overclock my phone due to lag/choppiness was with Virtuous 2.39 or whatever, months ago.
So ask yourself why you want to go higher. Bragging rights? Quadrant scores to show your mates? Do you even notice a difference between, let's say, 1.2GHz and 1.5GHz? Is it really worth it?
Think about it.
Cheers
So much detail, couldn't have said it better myself In short, 1 Ghz is enough for most, 1.5 is more than enough. Anything above that is DANGEROUS and should be avoided.

We are taking about the XL which has a single core 1.5ghz CPU.

I'm sorry if I missed the point, but is there anything overclocking that much is necessary for? I mean, I'm at 1,3 GHz max now but my phone runs at 1 GHz 60% of the time, rest of the time lower. I never reached something above 1 GHz.. ?
So why overclocking even more?
Edit:
My mistake, 60% of time it's at 245 mhz and only 30% of time at 1GHz.
But my question is still the same..

this guy just treated all of your lives! I love you bestofrhcp!
The thing is the moment runs at 800 Mhz stock so 1006-800= 200 Mhz overclock, or a 25% overclock. Our G1's were built for 385, but I've gotten mine stable up to 729, so an 89% overclock. Granted, the CPU inside the G1 was designed for 528 but HTC underclocked it for battery purposes, so it's only a 38% overclock. The samsung moment has a really crappy samsung chip (pre-hummingbird), but it should be able to squeeze out a few more mhz. I don't have much hope for anything more than 729 on our phones, at least not without an overvolt kernel and some sort of liquid cooling system.

I am really getting sick of all the overclocking nonsense.
There is MORE TO SPEED THAN CLOCK RATE!!!!
You can clock these CPUs as fast as you want, but the overall effect on performance will be measurably negligible. You may, at most, THINK that it is faster when in fact, it is NOT.

Hehe It might be placebo but Raging Thunder 2 is MUCH more playable at 700 Mhz than at 528.
It is true that there is more to speed than clock rate, I'm not going to argue about that. A Core 2 due at 3.3 Ghz doesn't compare to a Core i3 at 2.2 Ghz, since the core i3 has more cores and is a more efficient platform. But a Core i3 at 1.6 Ghz in a netbook won't compare to a Core i3 at 2.4 Ghz in a desktop. Clock speed can make a big difference in performance. You can optimize all you want but using brute force helps out. Of course I only overclock when I want to play some 3D racing games and I'm close to a power source. I usually run it at 352 or 480.

Why would you want to OC that much, I'm sure your battery last all of about 4 hours tops
I'm currently running phoenix ultimate w/Tagrak.
It's OC'ed at 1.3 GHz ATM.
It has made a seeming performance change to my phone. But i want to take it further and OC to 1.5 or even 1.6 if possible. After hours of researching, the CPU in the Cappy is capable of running at 1.6 at the fastest.
Does anyone know any APP that will allow you to OC higher than 1.3 GHz? and has OC'ed higher than 1.3?
Thanks a bunch
What kernel are you running? AFAIK the only kernel that supports 1500/1600mhz is Onix, which is the kernel I'm running. Best OC experience I've gotten on the captivate was 1344. I was using Phoenix with the Paragon 1344 kernel.
Once you get Onix, voltage control will let you OC to 1600, but you might not even be able to hit 1400 and stay on for more than 5 mins (my situation)
I'm pretty sure this should be in Q/A, no?
There is already a thread in this section (currently 4 posts down) about this topic.

the kernel needs to support the different timing modes used. onix will allow up to 1600. to my experience nearly all phones go up to 1200 a vast majority to 1280-1300 im barely stable @1300 myself. but 1344-1400 is the limit with only a few exceptions. every chip is different and i have a feeling the earlier phones had less consistant manufacturing. samsung may also be cherry picking chips that clock better for the galaxy s 2 mini which is supposed to be a hummingbird clocked up to 1400 out of the box.
keep in mind that 30% overclock is significant. if i tried that on my pc it wouldn't run very long.
I can get mine stable at 1.4 using Onix kernel and Serendipity rom. I tried 1.5 and 1.6 but was not able to get it to run.
I've come to the conclusion that OC achieves very little... UV even less.

I've been trying to map out the hardware, and near as I can tell without physically opening up the device...
Seems we have the 8660 version of the qualcomm snapdragon processor, and not the 8260 version.
The 8260 is rated at 1.2, the 8660 is rated at 1.5
I'm pretty sure that we have the 8660 governed down to 1.2 instead of the 1.5 it should be at.
Can anyone confirm or deny this and explain why?
I'm drafting a paper on snapdragon that i'll post when it's done - but honestly i'm taking a week off and just playing with the phone - all the games i've gotten and haven't really used and so forth.
Hmmmmmmm that would mean we have a better processor then the sensations. Ha +1 for Doubleshot. I will do some research on it and let you know.

Without actually pulling it and inspecting the processor, I looked at this thread:
http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)
which tells us that we have the 8260 chip. However, the 8260 and 8660 are both rated at 1.2-1.5, so who knows...
In the end we need overclock anyway just for fun, and WE NEED kernel source so we can get low voltage kernels!!!
it's a MSM8x60 series Snapdragon processor.
The MSM8260 is for HSPA+, and MSM8660 is for multi-mode HSPA+/CDMA2000® 1xEV-DO Rev.B. This basically means MSM8x60 will offer support for most of the contemporary mobile broadband air interface protocols such as HSPA+, LTE and WiMAX.
MSM8x60 features Adreno 220 GPU (88M triangles/sec, 532M 3D pixels/sec, 1080p video recording and playback up to 30 frames/second) and it supports for 24-bit WXGA 1280x800-pixel resolution displays.Not bad!
So yes 1.5ghz should be ok, since they are likely to be the same. but i m Wondering if you need a sort of special Thermal Compound or if it will be ok. Maybe a different battery, more amps since it may drain too fast and damaged the battery?

(not to cut out the helpful info in your post)
The anker battery solved my number one issue with a stock phone, which is heat. The phone would heat up tremendously, much more so then it seemed it should.
My theory was spreading the same level of drain over a higher volume of charge would help with the heat issue, since heat = waste. Lithium-ion batteries become extremely inefficient the more load is put on them.
I don't know if it's the quality of materials, or in fact the drain being spread over a greater volume is what solved the issue - most likely it was a combination of both.
If anyone has been following the development of the snapdragon, series 2 (we have series 3) processors suffered from severe overheating problems, resulting in the chip only being usable at lower and lower temperatures.
Overclocking our processor will definitely generate more heat. A stock battery will give the device a very low survival rate for such an act, though the aftermarket anker battery might give you a chance. Without the anker battery you'd probably have to have it plugged in to some power source to get any usable run-time out of it at full speed.
Thanks for posting some info on the processor - i'm confused because I know in build.prop it's listed as 8660 architecture - but i'm sure I saw the 8660 designation somewhere else in the system files - damned if I can remember where though.
Qualcomm doesn't seem to differentiate between the 8260 and 8660 in any of their documentation, and i've sent them an email to see if they'll clarify it a bit for me - though I had no business to send the email from so I doubt i'll get a reply.
I have tried it and it doesn't work properly, my battery drains out like hell.

Don't know if it means much but I just ran CF-Bench and it lists the board platform as msm8660. If it is the same processor as the EVO 3D, it explains the earlier rumors of it being a 3D phone when leaks first started to show up on the web. A quick search on PDADB.net shows the EVO 3D as the oldest phone with that processor. It also shows the 4G Slide as a 8260 so I guess we just need someone to physically look at it. It would be interesting for someone with a sensation to see if CF-Bench reports a 8260 or 8660 for them.

1.8 Ghz? How?
Excuse me, I should say you can get it to 1.8, but 1.6 is the the highest that's really stable. I seem to have read that may people have gotten 1.8 with few issues however.
Sent from my SAMSUNG-SGH-I997 using xda premium
There was a kernel that reported 1.8 incorrectly.
I have looked at those 1.7 GHz kernels and there is some interesting development going on with voltages to make it more stable but it is a weird bastard conglomeration of clocks and those kernels have there own issues. The limiting factor it's not the quality of the CPU but that the multipliers are locked at no more than 8 times the buss speed. Overclocking beyond 1.6 means buss overclocking which causes all kings of issues that must be worked through often by under clocking other things. most infuses are perfectly stable at 1.6 with no special treatment like exists in those 1.7 kernels but heat can run away and cause crashes when using the cell and GPS radios. It would be cool to run some benchmarks on Miui with 1.7 GHz to see if you can break 5000 in quadrant but really it is only 6% more than what we have in a perfect stable form. Not to mention that the CPU is throttled and would rarely see that speed and tweaking the governor would probably do more for the user since going to 1.7 means compromises in other clocks and potential problems.
It's not a matter of possible but a matter of why?
And for the record the best experience I had with my captivate was on froyo with glitterballs' stream kernel which had some cool stuff going on with hardware acceleration running jfs lagfix at 800 mhz. If I could get some of that in a GB kernel that I could run at 600 or 800 mhz with the insane undervolt my CPU can tolerate I'd be in heaven. Battery life for days!
does anyone know if setting the CPU SPEED to 1.5 GHz is dangerous while the SENSATION XL has the same chipset as the desire s has (Qualcomm Snapdragon MS8255) and the SENSATION XL's CPU speed is set to 1.5GHz .
sensation has msm8260 (dual core 1.2-1.5 GHz and adreno 220)
Sensation XL indeed has MSM8255.
Just like in PCs, chipsets in phones are binned not only by their type, but also by their target frequency. You don't go overclocking Core2Duo 1.8 GHz to 2.4 GHz because it's "the same CPU", right? Because it isn't the same CPU. The same applies here.
אז זה מסוכן או לא ?
English, please.
Answer - would you run the CPU on your computer at 1.5x the speed it was made to run, because there's CPU with the same name (i3/i5/i7/whatever) that runs at 1.5x the speed?
The same answer applies to your phone.
I expect people to be able to make minimal logic work with their own brains rather than just answering "yes/no". I think that this way people actually understand more than what they've asked for.
i guessed that was the answer but just wanted to be sure...
thanks anyway !

No it won't. It depends on the specific part, and few parts run stock 1.5 GHz without stability issues surfacing / burning out very fast (if overvolted).
If you really want - you can try it on T-Mobile G2, that has MSM8255 of the earliest bin, with stock at 800MHz. Good luck, don't forget to write how did you like a phone as a toaster.
I suggest refraining from bad advice, especially when it's in the forum and it's not your phone you're talking about. You can burn your phones as much as you like, but don't go around suggesting it to others. Just let me understand something: you have stock non-rooted ICS and have no idea about such basics as which guide to use to downgrade, but you allow yourself posting about chipset frequencies?
