our gpu is lock to 200mhz so is it possible oc to 300mhz? play games will more smooth than now
because i saw some phone can oc their gpu like htc sensation

i think our phone's gpu would be burned if oc till 300mhz
PowerVr SGX530 can be oc'ed only to 220 Mhz i think,that was the limit for OP Black too
sad......

I'm that this has been brought up before but could someone tell me how overclocking the GPU is done? It seems to me that the CPU is the most stable and is fine at 1200 MHz and going any higher is just a battery killer. But the GPU seems like it's severely underclocked. (or at the very least could do with some OCing )
Are there any apps that support it on the Charge or some tutorials that can show me where I can experiment with some numbers. I know my bro's Galaxy Nexus kernel has GPU overclocking built into it.
Feel free to give me bad news but if there is any hope i'm up to some leg work and phone sacrificing. lol.
It requires kernel support. PBJ overclocks the GPU some, but it isn't customizable. Beyond that, there isn't a way on the Charge.

GPU OCing from a UI isn't possible on this device-AFAIK its only possible on the GSII (maybe the nexus). The PBJ kernel OCs it a bit, but imnuts wants to ensure stability vs raw speed.

OK i have read up a little about live oc, but really i still dont understand it.
In NS tools there are 3 settings.... a % an "oc target low", "oc target high"
As i understand it the percentage is just how much each step of the cpu scaling gets bumped... so if your at 110% @ 1000mhz step it would actually be 1100mhz. And @ 110% the buss speed would be at 220mhz vs the stock 200. (is that correct)
But as far as the other two settings... oc target low, oc target high... what are those?
Really im just looking for a little more incite on how live oc works.
Thanks guys!
You can tell it to live oc within certain frequencies. So if you only want to to be on live oc from 200-800mhz, you can set it to do that

AHHH ok so the min and max are the range in which the live oc takes place. below and above those min and max values it goes back to normal?
how much rise voltages from 1300cpz/100liveoc to 1320cpu/110liveoc?
Bus OC don't work at all. I've tried 3d benchmarks with and without this and there are not difference

you must not be doing it right or applying works for me
EDIT: you do realize it will only over clock the freq of the low target and high target.
For example you run your benchmark and your cpu settings are going to be affected on the I/0 scheduler and cpu governor.
if i run Sio ~ On-Demand @ 100/1000 and my Live OC is 1200/1400 your not going to be using the OC settings because its only designed to, to OC the freq you chose it to.
So to make it work for benchmarking purposes i would run Sio ~ Performance @ 1400/1000 or even 1400/1400 so it would only use those OC'ed freqs. and have the Live OC either 1400/1000 say @ 105% or 1400/1400 @ 105% so it run Straight OC'ed freqs only.
Is it possible to overclock the Adreno 225 GPU, I play mostly N64oid and FPSE on my phone. Its for FPSE mostly because of the Open GL plugin might see some increase by overclocking the GPU. Also dose any one know what its running at currently, i'm not really sure if overclocking the CPU also overclocks the GPU if they are synchronized or something.
Any other emulator users out there that love using their phone for game play?

Yea.....I was just wondering if we had a kernel that had it OCed yet....that is what I meant by possible...with some chips the CPU and GPU need to be scaled the same to work correctly. So if the stock CPU speed is set so is the STOCK GPU speed......I think...do we even have a kernel OCing the CPU for the VGSIII?
Not sure if your trolling or what but Desktop GPU and Phone GPU are two different beasts. Not many people really even care to check what GPU is on a phone and how is stacks up against other phone GPUs. For example the Mali 400 in the Galaxy S II in the US makes the Galaxy S III GPU look like an old Voodoo card next to a GTX 480.....just saying we got ripped on the GPU hardware upgrade for the US iteration of the Galaxy S series. Its actually a downgrade and it blows now that I don't have sprint(because their network is trash).
Currently Verizon does not have a GPU in a phone with 4G that can match the Mali 400. I don't want to wait until the Galaxy Note 2 comes to Verizon...seeing as it has the same hardware as the international version of the Galaxy S III just with a bigger screen. However if a OCed GPU does not get me the performance I am looking for then I will be jumping to the GN2 as soon as it comes out.
The OP of the kernel thread you decide to look at should say whether the GPU is OC'd or not. For example, both TW kernels Trinity and Leankernel have the GPU OC'd to 480 mhz. If you're asking can we users manually OC the GPU, then I can't help you with that.

No problem, Leankernel is only available on Rootzwiki whereas Trinity is available on both sites.

OK, first of all I'd like to apologise for all the questions I keep posting. Im quite a noob with android, and coming from an iPhone, it's been a big leap. I'm just overwhelmed by the android system and how open it is! But I do all this cool stuff to my android like everyone else, although I don't wanna ruin a £350 phone by doing something stupid without guidance! (I'm just a big kid really! ) Which is why I keep posting questions, because it's hard to Google/Search XDA for this stuff...
Whenever I search XDA for 'Nexus 5 Overclocking' all I get is ROM threads, so this will be a thread for everything [under][over]clocking! Share your most effective results, and ask the pros questions!
I'll start it off...
I've Underclocked before, but now I wanna Terry out some heavy emulators (dolphin emulator, Nintendo 64 emulator ect.) But I don't think my phone is powerful enough to run these games full speed underclocked... I want to OVERclock it now, so which apps do I need to achieve this, how do I do it, and what are the most effective values for it?
Thanks,
Pro_Vickers.

The kernel defines whether or not you can overclock.
There is no real need to in the nexus 5 though.
If it is choppy at 2.3ghz then there is something wrong with the emulator.
In context I play final fantasy 9 on the psx emulator fpse using opengl graphics (which is limited to single core) and still get a constant 60fps

Hi,
First you need a kernel with overclock (Franciscofranco, Trinity, ElementalX, etc...).
For the apps Franciscofranco have its own app (Francsico Kernel Updater-> FKU) and Trinity kernel also (Trinity Kernel Toolbox-> TKT), all available on the Play Store.
You can use a "generic" app like Trickster Mod, Play store too.
With the apps you choose your max CPU freq and it's done...
For overclocking there is no "most effective value" it depends of the voltage and what your CPU can handle. 2,4/2,5 Ghz seems reasonable (with some kernels you can go above like 2,8 Ghz).
Try a "safe" overclock first like 2,4/2,5 Ghz, and don't set the CPU freq "at boot" to avoid any problem like bootloop in case your CPU can't handle these freqs.
Maybe you'll need to raise a bit the voltage for these CP freqs, it depends of your CPU binning.
You can apply your settings at boot via the app when you are sure that all is stable (so after a few days of test with your use).
In any case you'll need to test in different situations to see if all is fine (hard and normal use)...

I've Underclocked and it's choppy, but I know it's not the emulators fault because of the reviews, and I've played with it before I Underclocked... The problem is, I forgot how I Underclocked, so can you tell me how I clock it back to stock GHz?

I have Franco kernel so clocking shouldn't be a problem should it? Also can I use trickster mod for it? Thanks

Hi,
I've Undervolted -75, so should overvolt or set it back to stock values so I can safely try out 2.5Ghz?

Try with your undervolt...
But in first I would try with the original voltage, not necessary overvolting...
Try and see, only you can know if it will be safe or not...

You only see this CPU freq? Maybe your phone is actually to hot and the CPU freq is decreased?
"Click" on Max CPU freq then scroll down to see all the CPU freqs...

Ok...
Hum... you choose the one you want, you want to overclock so overclock. The stock CPU freq is 2,26 Ghz so if you go above this freq you overclock...
Maybe it's why "But I don't think my phone is powerful enough to run these games", like you said, if your max CPU freq was at 960 Mhz...?
Default the stock max freq will be 2260 MHz or 2.26ghz depending on how it's displayed.
I'd leave your undervolt as it is for now and just increase the max frequency and see if it becomes smooth for what you need

I know that my phone is fast enough (obviously, it's a nexus 5 beast!), and I know that I lowered my CPU frequencies, but it's just that I forgot what the defaults were, and how to change it. I know now, thanks you guys! P.S should I change my min frequency or is that fine?

Ah ok, you should have explained it at the beginning... , you're welcome
Stock min CPU freq is 300 Mhz..., not sure you'll see any gain to set it to 422 Mhz...
Set it again at 300 Mhz and see...
In any case if sometimes you have a doubt about some stock settings, disable the set on boot option and reboot, all the stocks settings will go back. Or in FKU, App settings then clear data for FKU.
