Notes
-All settings can be adjusted with the ElementalX app
-Defaults to stock CPU frequency, to use higher frequencies, do this:
Code:
echo 2499000 > /sys/module/cpu_tegra/parameters/cpu_user_cap
GPU is not overclocked by default, change like this:
Code:
echo 984000000 > /sys/kernel/tegra_gpu/gpu_cap_rate
-USB fastcharge is disabled by default, to enable:
Code:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
-fastcharge increases input current from 500mA to 900mA.

OC and NTFS support! Thank you for that!

---

Yes!! Used your kernel on the Nexus 5 and it was amazing
Smashed down on the mighty Nexus 9

---

Tytyty
Edit: almost 60k!!

---

60k that's sick!

---

This has made my day, really pleased your here!!!!!

---

This is wy i love XDA
would love to now how much the usb fast charge will diver from normal charging.

---

oh lawd elemental X is here....

---

Maybe a stupid question but is the fast charge safe?
And is there someone who felt that 2.5ghz oc made the tablet unsafely hot?

Normal is 0.5A and fastcharge is 0.9A, so almost twice as fast.

USB fastcharge is safe for the tablet, as it can handle up to 1.5A. There is a risk that the computer you are plugging into can't deliver 0.9A, as USB spec is 0.5A, but I've never seen a motherboard that can't handle it. Some USB ports will limit to 0.5A, in which case fastcharge will have no effect.
Also, you have to replug the USB cable after enabling fastcharge in order to get the higher current.
The tablet should stay around the same temperature while overclocking, as the thermal trip point is the same and the overclock is only 200MHz. However, there is always a risk of instability when overclocking.
