EvilZ Kernel pushes HTC EVO 4G LTE clock to 2.1GHz

6a00d83451c9ec69e20167665a8808970b 300wi - for some reason we don't have an alt tag hereZarboz is a developer who’s released a working custom kernel named the EvilZ Kernel for the rooted HTC EVO 4G LTE, that can overclock the processors to 2.1GHz on some EVOs and still run stable.

Overclocking the processor generally causes the phone to run faster, but eats up more battery life and in some cases actually slows the phone down at certain speeds. It also causes more wear and tear on everything, as the phone runs hotter. (However in two years of overclocking the EVO 4G LTE’s predecessors, I still have yet to blow one up.)

The performance gains by the overclocked kernel show up in Quadrant scores as about a 7-10% increase by going from 1.5GHz to 1.9GHz, so there are some improvements to be had. Most EVOs can overclock to under 2GHz, but if you manage to overclock and lock your EVO up, you may simply have to wait for the battery to completely run out – power+vol-up+vol-down is evidently a kernel-level power-switch, and not a hardware-level one.

The kernel is still in beta candidate stages, so it might not be wickedly stable at the moment. But it probably will be soon enough.

One other interesting tidbit about the development of this kernel is Zarboz created this without having an EVO 4G LTE in his possession. All work has been done blindly, with testers reporting back on what’s going on.

  • You could just pull the battery… oh wait… :D

      Oddly you can, was reading about how to do it. Does take a micro screwdriver though.

  • Moving to RC this week and starting on some AOSP

    the battery is actually a torx 6 youll need and the light grey piece of plastic under the “back cover” there are 6 screws you will need to remove.. once removed you will notice a small white plug.. this is your battery plug. you will need to use tweezers to seperate the contacts just be careful nto to bend them.. and bam battery pull.. Good news is.. my betas are over it and have a RC working now

    Thanks for the mention guys!

      rock on, next major step feel free to drop me a line and I’ll take a look at your kernel. Not that my looking does anything other than spur me to write about it or not.

      Glad to see more source-level kernel devs for the LTE out there.

  • I saw that the few i REALLY liked jumped ship for the S3 … i have abuddy with a LTE and he was having some dropped frames ona video

    well that started kernel work to OC gpu for him

    and figured i should share

  • Paul have a few Rc canidates up

    adding in sweep2wake as we speak :D
