doubleshot Overclock kernels

WARNING:

Installing an Overclock kernel on your device could have negative physical consequences (Read: broken hardware) if misused/abused.

Please educate yourself on what overclocking does and how you can melt your processor.

You proceed at your own risk and any damage that may result is the sole responsibility of the end user.​

Gingerbread kernels:

OC 1.5-A HTC 2.6.35.10 (Gingerbread) kernel

- 1.5GHz maximum CPU clock speed.

- Undervolting? Slight

- Insecure boot, see below:

boot.img - Insecure (default.prop):

ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.service.adb.enable=1

kernel Info:

- Modified CPU table to accomodate Qualcomm 1.5GHz S3 Snapdragon chip speed.

- HTC cuts it off at 1.2GHz on the stock kernel.

- Re-scaled CPU table and L2 cache.

- Max voltage 1.2 volts even at 1.5GHz (HTC was 1.25 volts @ 1.5GHz)

Voltage tables to be posted later - no voltages exceed what the stock kernel came pre-coded with, and we have undervolted the 1.5GHz frequency to 1.2 volts instead of the 1.25 volts HTC put it in for. Runs fine at 1.2 volts, has been for months for me.

(we used that 1.25volts at 1.7GHz instead...)

Otherwise all voltage tables are back to HTC stock, and new frequencies leading to 1.5GHz HTC did not put in had the voltage used from the lower frequency beneath it.

1.5 GHz is where the 'Two-Headed Snapdragon takes flight'.

(quote is the title of a Snapdragon white-paper)

The idea here is to give the superscaler dual-core processor the scaling options to choose from to take advantage of that ability...

OC 1.7-A HTC 2.6.35.10 (Gingerbread) kernel

- 1.7GHz maximum CPU clock speed.

- Undervolting? Slight

- Insecure boot, see below:

boot.img - Insecure (default.prop):

ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.service.adb.enable=1

kernel Info:

- Modified CPU table to extend to 1.7GHz clock speed.

- Re-scaled CPU table and L2 cache.

- See post 5 for the list of CPU frequencies.

- Max voltage 1.25 volts at 1.7GHz (HTC had 1.25 volts @ 1.5GHz)

We used the 1.25 volts HTC laid out for the 1.5GHz frequency for our 1.7GHz frequency instead. Runs great! ...and we stay within a voltage level that was already recommended to us through the code by HTC, so we are probably not putting too much voltage through the chip yet.

(we'll even see if we can knock that down a bit too, soon)

If 1.5GHz is where the dragon takes flight, then 1.7Ghz is where it starts razing villages ~ !

1.7GHz is where this device is most comfortable (in my opinion).

NOTE: 1.7GHz is above ANY manufacturer recommendations -

you are your own warranty now

. (pay out of pocket for breakage - you've been warned)

...The idea here is to give the superscaler dual-core processor the scaling options to choose from to take advantage of that ability:

I said that in the 1.5 kernel, but it's moreso true in this 1.7 one. There are a lot of options for frequencies that the Scorpions can use to scale to exactly the right level of effort needed to get the job done.

I am not sure at what point the table becomes too bloated and we see a hit on performance. I doubt very highly we've hit it yet, especially given the testing i've been doing - this is more a worry for pushing higher then 1.7GHz then here, but something to put out there now.
