PVS Bin - Xperia Z3 General

Update: I added a poll.
What do you guys have for PVS Bin.
PVS 5 on mine.
You do not need root, I used RootExplorer ironically enough.
Steps:
Go to sys/module/clock_krait_8974/parameters
Open table_name

PVS 7, bin v1
is it good or bad? lol

Higer the PVS number lower the voltages for the frequencies in the table.
However its not guaranteed that a higher PVS Bin CPU can OC higher than a lower binned part as they take samples when doing binning, so there could be lower binned parts that OC just as high as higher binned parts and vice a verse.
HD2Owner did a nice table here:

It is useful since it uses less power and heats less by CPU clock voltage ratio set by Qualcomm...
Ok just to be clear all are Speed 3 and v1 but PVS is different, mine is 8

PVS 8, you have nice one. I am usually on the low side with my luck on most devices lol.

PVS 8 for me too :good:

PVS12
Sent from my D6503 using XDA Free mobile app

PSV 11

pvs4 [emoji22]

Pvs 8. What is the highest?

I believe it's 15.

pvs4

pvs7

In my 4 exchanges this week for defects, PVS Bin increased each time lol. Went from 5,6,7,8.
PVS 8

PVS Bin ?

So how does PVS BIN affects performance ?
a cpu with pvs bin 4 is a lot better than a CPU with PVS Bin 1 ?

.... I have 4 and no... can't OC, UC, UV... basically anything besides stock values the "lot better" cpu rejects...
Might be also the custom kernels fault ... who knows
Till now the pvs bin has zero info value...

There seems to be a bit of confusion, about the significance of the PVS value. They relate to Process Corners, and in part to threshold voltage, there is a lot more to it than that, but I'll keep it simple.
So far we've seen PVS values of between 0 to 6.
0 seems to indicate a SLOW corner, this means that its leakage current is lower than a 6, but its timings are slower. In theory, this chip should be good for power consumption, but offer less overclocking potential.
So, 6 means a FAST corner, this means that its leakage current is higher than a 0, but its timings are faster. Again, theoretically this chip offers good overclocking potential, at the expense of possibly higher power consumption.
Firstly, don't worry about it, all these chips have to pass Qualcomm's quality assurance, and lastly a higher PVS number is not necessarily the best, it depends on your priorities.
What you said was correct, I couldnt have explained it that well.

Its just binning based on samples from those batches, you could still end up with an OC dud despite having higher PVS as they only sample a few and cant test every single one. But as the guy before me said they all meet quality assurance standards.
Lower voltage can mean lower heat, but there are other factors also at play.

[GUIDE] Snapdragon 805/801/800/600 Clock & Voltage (PVS bin) guide

hi
i did some research regarding the topic and want to share my finds/work with everyone.
the comparison shows all pvs of MSM8974AB 2.3ghz (one m8 - pro_rev1_2p3g) and MSM8974AC (gs5 - pro_rev1_2p5g).
all table data manually taken from latest one m8 kernel sources.
in addition i added one m7 (APQ8064) and lumia 930 (2p2g) chips (pvs0 and pvs6) for intresting comparison.
with this guide in combination with root access, custom kernel and trickster mod you can find out your cpu's pvs bin (compare default voltages).
alternative to find your pvs: adb shell from recovery (su) "cat /proc/last_kmsg | grep bin: -i".
also it serves as a template to try out higher pvs settings on your cpu.
as you see, qualcomm did some impressive work with binning and trying to get most out of each cpu.
however there is usually still some headroom for optimizations if you do some efforts.
same research i already did for the m7 (APQ8064 compared to APQ8064T of galaxy s4) if someone is intrested (let me know).
happy clocking/volting!
i take no responsibilities for potential harm you do to your device. all on your own risk.
please share your results of which pvs level works on your personal chip (also tell stock pvs value of course).

best min frequency:
lowest possible setting (300mhz in case of MSM8974)
i highly recommend to run those values (exept if you are actually playing demanding 3d games).
use trickster mod frequency lock feature to do so. you will experience amazing battery life.
how to get the maximum battery life:
if you have a MSM8974AB pvs 6 for example, try the following steps:
try the next higher pvs levels (pvs7). don't try AC pvs values on AB chips.
AB chips are binned for lower frequencies while AC are binned for higher frequencies (duh).
so if you have a AB chip, work your way up the AB pvs values until you have freezes or similar and move back.
if you have a AC chip, work your way up the AC pvs values etc...
if you found highest setting that does not cause any problems after intensive testing and usage:
congratulations, you did it. :good:
how to get the maximum frequency:
first try higher than stock maximum clock and see how it behaves.
if you don't reach your desired clockspeed, try the next lower pvs setting of your chip. yes, i said LOWER.
this gives the processor more voltage to reach higher overclocks.
i don't recommend it tho since we all want our phones to last as long as possible usually.
signs of too high overclock:
device lockups (not responding) or sudden reboots during heavy load.
signs of too low voltage:
problems with audio when screen off, long screen wakeup time, lockups and reboots even without cpu-load.
caused by not enough voltage for low frequency levels usually.
snapdragon 805 infos:
HD2Owner said:
here you go. i digged in the kernel sources and found it.
2.7GHz RC1 - speed2-bin-v1 (PVS levels 0-15)
2.7GHz RC0 - speed2-bin-v0 (PVS levels 0-15)
2.5GHz RC1 - speed1-bin-v1 (PVS levels 0-15)
2.5GHz RC0 - speed1-bin-v0 (PVS levels 0-15)
2.3GHz RC1 - speed0-bin-v1 (PVS levels 0-15)
2.3GHz RC0 - speed0-bin-v0 (PVS levels 0-15)
there seem to be two different variants of the 805 (RC0 and RC1).
RC0 seems to use less voltage at higher frequencies.
RC1 seems to use less voltage at lower frequencies.
the voltage tables you can take from the attached txt.
i also attached a txt containing how the bus clocks behave in relation to the cpu-frequency.

enjoy and leave a thanks if you like it please.
edit v2:
fixed some flaws (22 downloads of v1)
@HD2Owner, seems like this would be better in an Original Dev section?
I realize that there's no place on XDA anymore without non-dev clutter, but this information - and a discussion of it - would seem to be better alongside kernel work than in the same section as "India chat", "British chat", "USA chat", and "I'm too lazy to read any thread so I'm going to post a question that's been answered 50294 times in the past 24 hours."
(I'd request a mod to move it, but it's your thread...)
Take care
Gary
sure.. it's not actual development but closely related research yes.
Sorry for the n00bish question, but what can I actually do with this? Im guessing some kind of undervolting / overclocking?
I am running ElementalX Kernel and have the Trickster Mod app installed.

Yea it's for understanding where you device Falls on the overclockability / how much voltage you'd need at different OC rates scale

that's what i want to see here.. :highfive:
i will enhance the first post later with m7 vs gs4.
probably also some general guidelines.
but i need as much info as i can gather from different bins and experiences to make conclusions.
the plan is to post trickster mod voltage settings for all 32 pvs levels when export/import works.
until then you need to manually try the values. please stick to the posted values or report in detail.
@ moderators: feel free to move the thread where it fits best
I am using elementalX with undervolt -45. The values I get from trickster mod do they take into account the undervolting of the kernel or is it something more global that trickster mod does not show?
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.)
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
added some more infos and conclusions in first post.

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!

I'm surprised you guys don't know this but we z1 users have a snapdragon 800 vv and guys instead of overclocking you should focus on undervolting and underclocking because even at 200 MHz GPU max and 1.6 GHz CPU max with -95mv undervolt I have no performance drops in gaming(dead trigger,avabel,etc) compared to stock except the heat has reduced and battery is a bit longer...
Lastly look at the screens in the post after the next post

What's your CPU PVS bin #?

Just out of curiosity, I 'd like to know what everyone's cpu PVS binning is. This makes little difference unless you're trying to undervolt, but it doesn't hurt to know.
Non-Root How To:
Use a file browser (I used Root Browser) and navigate here:
Code:
/sys/module/clock_krait_8974/parameters/table_name
Open up "table_name" as a text file. Mine read: qcom,speed3-pvs7-bin-v1. My PVS bin # being 7 on a scale of 0-15. 0 needing the most volts, 15 needing the least at corresponding frequencies (I think I got that right). Overly simplified that would be higher binning=better, but again this makes very little difference.
Here's a example of stock volatges at 2.5 GHz for the MSM8974AC Rev 1:
Code:
PVS 0- 2.5GHz @ 1.12V
PVS 7- 2.5GHz @ 1.05V
PVS 15- 2.5GHz @ 0.97V
Here's a thread from the OnePlus One forums that's helpful if you want to know more:
http://http://forum.xda-developers.com/oneplus-one/general/info-cpu-binning-concept-overclocking-t2817105/ (Note: Moto X's chipset seems most similar to the MSM8974AC Rev 1 or at least has the same binning)
Thats pretty interesting, never heard of this before.
Mine says 6. Guess mine is using a bit more volts?
Mine says 3. Huh?
5...v1 which according to one plus forums means 2.3ghz?? Sad times v2 is 2.5 apparently
Mine said pvs4, but what does that mean?
Is lower better, or higher?
I googled, but noone else seems to be sure either.

No where did you have this from?
The moto x has the msm8974ac and this one has 2,5GHz... According to cpu-z 2.46GHz (or more exactly 2457.6 MHz says antutu device info page)
Msm8974ab has 2.3GHz.
Yeah, the X uses the AC @ 2.5GHz. I think that's what the speed # means. The version in "table_name" is the PVS version not the CPU version. Not sure what that is though. Maybe the parameters used in sorting?
Mine says 8.
8 here as well... Damn had a 13 on my old moto x lol

Droid Turbo PVS bin

What is the PVS bin? It is a known fact that not all semiconductor chips leave the factory equal because of complicated baking process, and for most expensive complex articles like CPU and GPU manufacturers introduced a sorting practice called "binning". Qualcomm also has such scale for their chips, that consist of PVS value range from 1 to 15, to aware Android software how many voltage it should apply to CPU on a certain clock to run error free. The bigger PVS value is, the lesser power required to run CPU stable. So, the story is about energy effectiveness.
Please, share your Droid Turbo PVS bin in a poll.
How to know your bin: use file manager to go to the path /proc/cpu/, and open file msm_acpu_pvs as a text.
PVS bin value is stored as a hexadecimal, so when you see a letter instead of a digit, convert it to decimal like: A=10, B=11, C=12, D=13, E=12, F=15, and vote in the poll above. Thanks! )

LOL. Sorry, added poll lately ) Mine is 6.
Voted. Mines 8.
Does this essentially mean I can undervolt more before the device becomes unstable and reboots, than someone who has a PVS value of let's say 2?

Yes. Probably, your SoC CPU cristal with "8" was in the center of semiconductor wafer, and mine "6" was somewhere closer to the side
The difference in voltage applied not so big, I guess, from 0 to 20mV max in your favor.
As for the "2" CPU, it is tougher, and will be auto driven by higher voltage. Or we set it manually by installing custom kernel with voltage tune support, and try to earn your effectiveness. But then, again, you can start manual control too, tuning voltage down, and Turbo with "2" will suck (

Interesting! Thank you for the explanation! So I guess that's why I'm able to undervolt -70mV without encountering stability issues, where others would get reboots if they did the same.
Mine is 6 and was written as digit
I have a 64gb turbo with 2 :_( :_(

Mine was 6 (which I voted-in)
My wife's phone is 4 (which I cannot vote-in because the poll won't let me vote twice)

) I can't double vote too, having 7 pcs by the hand. PVS bits on them are: PVS4 - 1 pcs, PVS5 - 4 pcs, PVS7 - 1 pcs, PVS9 - 1 pcs.
