Just came across this on phandroid. Good stuff.
Without Kernel Source, HTC EVO 3D, Sensation 4G Get Overclocked to 1.7GHz Stable
Without Kernel Source, HTC EVO 3D, Sensation 4G Get Overclocked to 1.7GHz Stable
I'm probably in the minority on this, but I'm happy with my stock 1.2ghz Evo3D with the standard interface. I have no plans to root when we're able to.
However, I'm really happy that the root'ers and mod'ers will have the opportunity to open the Evo3D up and see what it can really do. It's going to be fun to watch!
Well based on phandroid, there was no root required.
And I'm against that temporary root. It raises temperature and lags the phone while beating on the eMMC controller.You rooters already know how trustworthy and talented this guy is so you’re free to get as excited as you want. This is a loadable kernel module so all you’ll need is temporary root, something that’s already been made possible thanks to the folks behind Team Win.
Steady - from Phandroid:

I've warned that XDA posts that temp root is meant for devs to find more holes right now and is not for users.
The only two guys here on AF who've chimed in reporting they've done the temp root are myself and wake69.
You all do as you think best, but whatever you do, please don't assume this is at all safe yet.

I'm on record that I hate free Quadrant - but my question is: are you sure about what you think you're getting?
Here is my phone, no temp root running since last weekend, stock-a-roonie, in other words.

Didn't kill anything, didn't restart phone - just downloaded the thing and launched it from within Market.
Either proving what I've been saying about Quadrant or what we both just said about not trusting this temp root.
EVO 3D and Sensation @ 1.8GHz!
HTC is taking far too long with their promised bootloader unlock! I got my hands on an EVO 3D and wrote a kernel module to overclock it (along with the Sensation, I think) with just temp root. I had no kernel sources or the ability to flash custom kernels, and you don't need to overclock your phone, either. This was all done with a Linux loadable kernel module.
At 1782MHz (nearly 1.8GHz), a dual core Android phone is truly a force to be reckoned with. This module also gives you the flexibility to try to go even higher, or specify a lower overclock. See below for instructions and download. SetCPU has also been updated to support the EVO 3D and Sensation better. I'll be doing a technical writeup on how this was accomplished soon, as well as an explanation of the MSM 8x60 clock architecture for future kernel devs.
Disclaimer: Overclocking your phone is always a risk! Please know what you are doing before trying this. The kernel module is licensed under the GNU GPL and comes with no warranty. The relative safety of overclocking similar ARM processors to such speeds and voltages is generally known, but I can't be held responsible if you damage your phone with this hack.
Instructions:
Download the kernel module appropriate for your phone If you're not sure which one to download, check /proc/version and find the version string and then check the part that contains the localversion, which is right after 2.6.35.10 and looks like this: "gb7a86da" or "gcb1cf8"

(To add support for your EVO 3D/Sensation kernel, send me the kernel version string (cat /proc/version) and I'll upload a kernel with support).
1. Temp root the phone using fre3vo, and install everything you need to run root apps. If you lost temp root due to /system/bin/su becoming unlinked (root apps don't detect root anymore), do it again. Thanks #teamwin!
2. Decide which frequency and voltage you want. Frequencies have to be a multiple of 54MHz. For example, 1512MHz = 54MHz*24. Remember how much you have to multiply 54 by to get the frequency you want. For 1782MHz, as I reached, use 33 (54MHz*33 = 1782MHz).
3. Push the kernel module to your device: adb push 8x60_oc.ko /data/local/tmp/8x60_oc.ko
4. Use SetCPU (you must be 2.2.4 or above for proper MSM 8x60 support!) to set the max frequency to 432MHz and min to 384MHz.
6. Go back to the home screen, press the power button, and count to ten.
7. Load the kernel module with the following command, replacing the scpll_l_val with the value you got above and the vdd_uv with the voltage you want (in microvolts). Here is a valid command for around 1.8GHz: adb shell insmod /data/local/tmp/8x60_oc.ko scpll_l_val=33 vdd_uv=1375000
If you do not specify any parameters, the module defaults to 1512MHz and 1250000 uV! (scpll_l_val=28 vdd_uv=1250000) This should be safe for everybody, since that's the MSM 8x60's native speed (of the higher speed bin anyway).
8. If it crashes right after you insmod the kernel, reboot and try again - the second core was likely still active. This doesn't necessarily mean your overclock settings were unstable.
9. Now go into SetCPU and it will autodetect the new max frequency. Set it and try it out. If your phone crashes at or after this point, the scpll_l_val and vdd_uv combination was not stable enough. Reboot and try another combination.
Note: the maximum scpll_l_val supported currently is 37 (1998MHz, or 2GHz!). Let me know if you actually managed to reach this with a semblance of stability, if you want to push for higher... Also, you can undo this mod just by rebooting.

Enjoy! Of course, this would all have been easier if we were just given an unlocked bootloader. Please bother HTC about it!Yeah, we'll get it without them, but they have to keep their end of the deal.

Sources for the overclock module: http://dl.dropbox.com/u/36553/8x60_oc.tar.gz I'll be uploading it to my github soon. It's messy at the moment.
Much better because now there's a running chance at seeing what contributed to the overall numbers.
Honestly, I'm surprised the 2D and 3D graphics are so low and the IO is so high - but if that's how the cookie crumbles, then that's that.
Disturbing to me, tho, that there's such a difference in the total from your run the other day.
But if true, on their relative scale for the software library functions they call during their test, about the IO of the Droid X2, a bit better than the Hummingbird for 2D+3D graphics and about a 70% improvement over the Nexus 1 CPU. Not really bad. (Especially noting OS and display resolution differences.)
If other reports I've seen are true, that's on par with stock SGS2 or LG Optimus 3D.
As a Quadrant Advanced owner, do you get any access to what those tests are made of?
