One of the "benefits" of CyanogenMod on the Nexus One is the kernel (by "Pershoot"?) that supports overclocking the phone to 1.113GHz.

The usual Nexus One top speed is 0.998GHz. 

I can't do 1.113Ghz reliably. I've tried several times. It locks my phone up within 15-20 minutes pretty much every time. Sometimes almost immediately.....and that's annoying. :-)     

But I backed off to 1.076GHz and it's solid as a rock. I'll take a 9%-10% performance boost. Ta.

It also makes 720p HD video recording just that wee bit smoother.  

How do others find overclocking your Android phones? Working for you?

What phone?
What ROM?

Just curious.... :-)

Can this only be achieved on the n1 due to it's open nature?

overclock can be done on most android phone

my xt720 omap 3440 is running 1ghz, its so much faster than moto's default speed 500mhz :D

have no problem with the phone never crash and stable battery and cpu temp yay

btw im running stock rom android 2.1 update1

whoa 100% increase?! That's incredible... people struggle with that on desktop CPUs cooled by LN2 and running huge volts... I understand the differences between that comparison, but still... wow.

No. It's just easier and there is a big community of competent independent developers. 

My understanding is that you need the source code for the kernel and you need to know what frequencies the processor will support. You can test for the second by trial and error, but you must have the source to be able to do anything.

The "SetCPU" app will let you set high CPU speeds, but the CPU won't actually do them unless the kernel that's running supports those frequencies and the CPU itself also supports them.

To be able to change to a new kernel your phone has to be rooted.  

Most of the Android phones have been rooted by someone. Whether or not the community around any given phone has the skill to compile their own custom kernel to allow overclocking is a separate matter. Many of them do. Certainly among the most popular phones that have been around for a while.

The stock kernel supports overclocking? That sounds outrageous! :-)  

How are you overclocking and what do you use to benchmark it?

I'm curious because "SetCPU" let's you specify target frequencies and it will report the phone as doing them......but a benchmark app (Linpack?) will show it isn't really going any faster than the usual maximum. It just *thinks* it is.

omap 3440 was design to run at 800mhz, motorola underclocked it to 550mhz for better battery performance, all i did was slightly overclock :D

here is how i did it:
1-get root access
2-install milestoneoverclock 1.2 apk or updated 1.32 from xda forum
3-setcpu to set different profile to save battery

i thinks its actually much faster, not sure about linpacl or nechmark tool u r using.
i use quadrant benchmark my result was almost doubled

at 550mhz i scored ~360
at 1ghz i get ~600

battery temp 16(not using)~42c

my benchmark result shows
1-nexus one 2.2
2-moto droid x
3-samsung galaxy S 2.1 (sgx 540 gpu same as iphone4)
4-xt720 2.1 (sgx 530 gpu)
5-nexus one 2.1
6-htc desire 2.1
7-moto droid running at 550mhz

SGX520 (7 MPolys/s, 250Mpx/s@200MHz) for the handheld mobile market SGX530 (14 MPolys/s, 500Mpx/s@200MHz) for the handheld mobile market
SGX535 (14 MPolys/s, 1Gpx/s@200MHz) - SGX540 (28 MPolys/s, 1Gpx/s@200MHz, Max Memory Band (GB/s) 4.2GB/s) for handheld high end mobile, portable, MID, UMPC, consumer, and automotive devices
SGX545 (40 MPolys/s, 1Gpx/s@200MHz)

above is from wikipedia, so no doubt SGS is faster

anyway ill try to get a screen shot of the result, so we all know how its perform

Thanks for putting me on to the Quadrant app. It looks great!

Here is my benchmark. Just ran it and took the screenshot with ShootMe!....then added a title in PicSayPro and sent it to myself in email.

I have a Nexus One running Android v2.2 (CyanogenMod 6.0 RC3) and I'm overclocked to 1.076GHz (approx).

Well, with various 'lag fixes' my otherwise stock SGS scores up to 2300 - but I take that with a pinch of salt. And not OC obviously. I think I've seen 2600 scores for the SGS with OC on xda.

Well done! :-)  

I ran another one last night and it was 1476....higher than the one I posted. 

Then there is this startling result from the guys who write CyanogenMod.

Maybe they run it an emulator on a really fast PC. :-)  

Or maybe they overclock it all to hell and hope they can complete ONE test and screenshot before it locks ups....

Or maybe Photoshop....these guys have a sense of humour.
