PVS info are unavailable on the galaxy S5 and the command on the terminal emulator isn't working,with that in mind checking the PVS binning is done in this directory :

/sys/devices/system/soc/soc0/soc_pvs

The issue with elementalX is that the undervolt only works for the lowest clock value and doesn't apply for the rest. Check in Trickster Mod and you'll notice that it's only applied to 300MHz.

also, even without root access, you could use adb bugreport >bugreport.txt then grep the file for infos.
On my note3 with Android 4.3 I don't get any Bin strings but ...

Hmm I can't get over 2.4ghz.
Locks up. Although elemental voltages seem a lot lower than those cited in the document attached to this thread.

I do wonder, is kernel tweaker successfully amending voltages?

I tried to ramp the voltages up whilst in power saving mode, then disabled power saving mode, but it locks up and restarts.

I would of hoped 2.5ghz is easily attainable as I thought we had the same processor but clocked to a lower frequency compared to the S5 etc.

Would appreciate some help with oc'ing.

I am PVS 12 and I've set the voltages specified in the spreadsheet with stock frequency and when I am running Antutu X, CORE 1 is stuck at 1%. I am not sure if this happens with default voltages too or if it's kernel related because I am running ElementalX 0.19. I've rebooted and I am trying to reproduce it now

EDIT: I've tested it with stock voltages, and I get the same problem. I am using Insertcoin ROM and the usage statistics of Insertcoin Control on the notifications(picture attached. Picture just shows the tool I am using. Not the moment when CORE1 locks.)
Picture

Is there a chance that it's not showing correct values for CORE1? Is there another app I can use to test the core usage while benchmarking?

EDIT2: I've found the problem. Everything works fine when I uninstall trickster and then restart. After I install trickster and run the benchmark, CORE1 locks at 1%-5% while others are 100%. I don't change any settings on trickster. Stock voltages and it does not even apply any settings on boot. If it is installed, no matter how many reboots I do, the problem persists. If I uninstall it and reboot, the problem is gone. I am really confused

EDIT3: Will it work if I change the UV_mV_table in /sys/devices/system/cpu/cpuX/cpufreq for each CPU Core? I want to change the voltage without Trickster because of the lock issue. Maybe we can make a flashable for each PVS that changes that file, so we don't have to use trickster

Just an addition.
You can get the pvs number in HTC ONE M8 with:

Code:
su
cat /sys/module/clock_krait_8974/parameters/pvs_number

Are you doing this while in recovery or while it's booted up?
You can try to navigate to that path using a file explorer and see if it's actually there. Make sure you have a file explorer with root capabilities. If it's not there, I have no idea why! :P

I don't know why you don't have it but try this:

Code:
cat /sys/module/clock_krait_8974/parameters/table_name
That should give you, your pvs too if you can't find it using the OP's instructions
