I tried to post a screenshot of CPU Spy, previously reseted timers and then ran BasemarkOS and Geekbench. (can't because less of 10 posts )
I see in CPU Spy that Max CPU state is 1555 Mhz? That's the A53 cores, right?

So what is the best app to monitor cpu activity?
And why are my benchmarks so low?
For instance, I'm only getting ~25k in 3dmark Ice Storm Unlimited, roughly the same as my previous Nexus 6.
According to Anandtech I should be getting ~36k.

Kernel Adiutor is a free kernel manager. I prefer using ElementalX Kernel Manager (paid app). Both work perfectly fine on Marshmallow, support HMP, and receive frequent updates.
If the phone is hot, then benchmarks will suffer. The big cluster gets throttled and goes offline whenever the temperature reaches a certain point. If it is running cool and you see low scores then idk cuz I don't do benchmarks.
Sent from my Nexus 5X using Tapatalk
If the phone is responsive and fast as you say why do benchmarks scores matter? Benchmarks are pointless, they give you a pretty useless set of numbers that don't equate to real world usage. If your real world usage is good (as you pointed out) then you're wasting time and energy worrying about something that doesn't matter.

I don't care about benchmarks, but they can point to a problem in your phone.
And I really would like to know how a phone sent to hardware testers consistently gets much higher benchmarks than the one I bought. Something's not right.

I've had eight of these and none of them have performed well in benchmarks. Take from that what you will but I believe it's a problem that's common to the SD810, not necessarily that you have a defective unit.

Can over clocking the phone can burn or cause damage to the hardware except excess battery usage and does overclock an 1ghz processor to 1.5 will really give a boost or its just a gimmick

Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!
Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.
OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.
My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine
Most OC kernals are also undervolted anyway so I wouldn't worry about it
to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.
It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...

If you use trinity kernel, you will be able to oC to 1.8Ghz. It used to be able to OCable to 1.9 but I think there were substantial issues with that level. Overclocking will ruin the CPU life span. Overclocking is more suitable for computers. This phone is really quick and smooth out of box. Overclocking it is redundant.

Good question but, to answer the OP 1.94GHz is the max. More may be possible however, no one is foolish enough to risk 2Ghz+.
Okay let's set this straight:
More Overclock --> Faster speed --> Lower stability
Increasing Voltage --> More stability --> Higher temperature --> Dangerous
To be able to achieve a higher clock speed, you need to have a higher CPU voltage in order for it to be stable. If you don't increase the voltage, the CPU will churn out corrupted data, and in the worse case files will become corrupted as they are written into memory. But it WON'T damage your hardware. However, because you are increasing the voltage, you get more heat, which can damage your hardware. So it's actually the overvolting bit that is dangerous, not the overclocking.
As for maximum clockspeed, you might find this article interesting:
"Theoretically, your upper limit would be due to the propagation delay in sending electrons from one point to another, which would be the speed of electricity. Electricity travels close to the speed of light and light travels a foot in a femtosecond (10E-15 s) so the top speed is somewhere in the 10E22-10E23 Hz range. However, this limit will never be reached as this assumes no capacitance and no resistance in the wire."
- Source: Mu_Engineer (http://www.tomshardware.com/forum/250325-28-limit-clock-speed) -
1 GHz is 10E9 Hz, which is nowhere close to 10E22. Even taking into account the resistance of the circuitry, 10E9 is still very low. So 1.94 GHz is simply the maximum STABLE clockspeed you can normally achieve on a Nexus 4. In addition, developers might impose arbitary limitations on how much you can overclock your CPU, but that's just a software limitation.
In conclusion, the answer will depend on which of the following questions you actually want answered:
1) What is the highest stable clockspeed the XDA community has managed to achieve without external aid (i.e. liquid N2)?
2) What is the highest clockspeed allowed by currently available kernels?
3) What is the physical clockspeed limit of the Snapdragon S4 Pro assuming external aids are allowed? (E.g. connecting your CPU to a higher voltage source directly while keeping it cooled with liquid helium. Even then it would probably only lasts for a few seconds.)

I won't because at the moment I fail to see any reason why anyone would need to OC their Nexus 4. So yes I am agreeing with you.
However, OP asked for the highest clockspeed, not for opinions on whether OC is useful. Saying that OC is useless in response to his question is similar to telling someone that they should eat at Burger King instead when they ask you for directions to MacDonald's. It doesn't make your statement any less true, but you are not answering his question.
With some Kernel like Faux you can OC up 1.94Ghz (Turbo Boost Ultimate) but not all CPU hold this frequency.
I think 1.83Ghz (Turbo Boost Mainline) is more reasonable.
Both Kernel just mentioned also OC GPU to 487Mhz.
Personally i don't Think we need to OC our Nexus 4, I've never seen a phone so fast

The nexus 4 is definitely a great phone for a low price.But people are not buying this phone because of this THERMAL THROTTLING.so,people listen nexus 4 even runs smooth with thermal throttling going on.so, this fix is for people who just dont want thermal throttling.Before we start,this fix requires ROOT and a custom recovery.And a custom kernel needs to be flashed.so if you do any damage to your phone by doing this,I'm NOT RESPONSIBLE.
So first download the faux kernel for nexus 4(codename mako. if you see mako on faux website its for nexus 4) from here: Faux's website which i cannot post because im new to XDA. you can find it by googling for faux kernel website.I recommend the TBM kernels such as mako-jb-kernel 016 tbm which lets you overclock CPU to 1.83 Ghz.But theres also TBU kernels which support overclocking to 1.94 GHz.
Step 1 now download a faux kernel of your choice.
Step 2 paste the kernel to your mobile
Step 3 Boot into recovery mode
Step 4 Wipe cache
Step 5 Wipe dalvik cache
Step 6 Install .zip kernel
Step 7 Reboot your phone
Step 8 Now you have to buy the faux123 kernel enhancement program from play store(this app is from faux and this has intelli-thermal built in it)
Have fun.the faux app lets you select CPU frequencies also
What.

With his enhancement app yes you can control throttling but the problem is that because the phones CPU is getting way too hot, so increasing the throttle threshold or limit basically makes it so when your gaming, it makes things smoother however your CPU is burning faster.

The nexus 4 throttling is caused by the battery reaching a certain temperature not the CPU. It's poor design/cooling system causes heat to build up which raises the temperature of the battery. Once it reaches a low 37 degrees the cpu/gpu are downclocked even if they are well within their limits.

the n4 has a battery temp throttle AND a cpu temp throttle.
i generally disable both the battery and cpu temp throttles, but leave both safety temps as is. for those that say "oh, the extra heat will eventually ruin the phone".. the temp doesnt get any hotter than it does when you normally use your phone, the difference is that you dont get throttled. and even if there was extra heat because of, im not planning on having my phone for the amount of time that the extra heat will take to ruin the phone(years).
Most people say that A57 cores are disabled on MM. But it isnt True. As you can see on screenshots, they are working. Please post screenshot from cpu-z on android N.
It's not disabled completely, they become active as needed when temp is under control for them to be active.

Nope... It's Absolutely true.. 4 cores got disabled and working cores got underclocked to 1.5ghz
Don't belive the're underclocked. A53 cores runs at 1,5ghz as they should. We just don't have any app that can read actuall clock speed of A57 cores. But if they're disabled, I should not get any cpu usage on them. And I'm getting cpu usage on them!
What more, why we have the same benchmark scores as in Marshmallow?
Did anyone test this on lollipop? The cores themselves may not be disabled but I did notice their lack of use, no matter what game or app I use the 4 extra cores stay at 0 %.
Benchmarks such as atutu maybe specifically written to utilize all cores, but seeing their lack of use in general use is troubling.
As for the downclock the specification for this A57 is 2GHZ according to this.
http://m.gsmarena.com/sony_xperia_z3+-6878.php
And I do remember the clock speed being different in MM.
And there's also this.
https://forum.xda-developers.com/showpost.php?p=62151047&postcount=17
So some downclocking was made.
Edit.
Something worth a note, thou some people may know this already, "Stamina Mode" does seem to hae some effect on CPU usage.
After disabling "stamina mode" or setting it to start when battery is low i started to notice some usage from A57 in general use, where before it was not used at all.

Well to truly test you would have to flash all the way to KK, as supposedly the cores are disabled on both MM and N.
But you are correct it doesn't matter, as the A57 is down clocked to 1.56GHz to match the A53, and the A57 is in constant sleep state, may as well be disabled, even when running full HD games it does nothing, i wiuld mind this that much if it helped to keep the phone cooler but even without the A57 Z3+ is a bloody furnace, 60C degrees on a cold day, when in use just browsing the web.
Did you notice any difference when testing MM and N, lags, slowdowns etc?
How about any benchmarks? in antutu i get from 50k to 80k and i didn't notice all cores being uses when beniching, the only way i ever saw all cores in use is when using a CPU stress app.
If i had to guess i would say that the phone switches between A57 and A53 depending on what you do bu i never noticed CORES 5-7 ever being used.
Hi there,
Is it possible to overclock the cpu and gpu?
If so how? Or which rom/kernel?
Running G model 4gb ram
Even if you can, it will chew the battery and heat up.

Not a problem as I would only be using it sometimes not permanently

in theory it is, we had a a kernel that OC'd the CPU way back then, but the SoCs on the Axons are probably low-binned - shutdowns and stuff like that are commonplace
But still, do you know what OC does to a phone? New phones are thermally constrained devices, starting from the snapdragon 800 series onwards. remember the sd805/810 disaster? Well...
If you run your phone at 100% load, it will run at max speed (1.56/2.15) for a very short time (say, 30 seconds), until the SoC reaches a specific temperature. After that it'll go down to a more manageable frequency, eventually going even further down or staying at 1.8 ghz, depending on your specific situation (the pink thermal blob might be bad).
That's why VR mode sets your cores at around 1.8 ghz, to keep them from going hot and lowering frequency even more. Sustained performance is better than burst performance on gaming.
Day to day usage is another matter, because more frequency won't mean thermal throttling when opening apps or unlocking the phone, beside the obvious battery usage
TL/DR: Be prepared to make your own kernel if you want to OC. It might not work
