Best kernel for overclocking? - Nexus 4 Q&A, Help & Troubleshooting

[First forum post!]
I recently flashed franco.kernel onto my 16GB Nexus 4 (rooted, PA3+) and I overclocked it, but I was wondering how far I can go. I heard about a possible 2GHZ overclock but I'm not sure what kernel that uses. Any suggestions?

A test kernel someone made awhile back when the nexus first came out it ran fine at 2ghz was a little hot at times but it worked :laugh:

Well, what is the highest that I would be able to overclock my Nexus, anyway? franco goes up to 1.7, I'm wondering whether it's possible to go any higher. And if I could go any higher, what kernel would I have to use? I'm just quite curious.

Faux has one that goes to 1.9 i think

test it. it doesnt test as a 1.9 kernel no matter how hard you try, its not really 1.9ghz. a 1.9ghz clocked cpu, will test like a 1.9 ghz cpu, not a 1.7ghz cpu. there are other kernels that go to 1.944ghz also, they test like 1.944ghz. but that doesnt matter, most phones will not be able to run at a "real" 1.944ghz.

Mine runs at 1.944 just fine, with an undervolt of 150 across the board

bench it, show me that it benches like 1944mhz. just because it says 1.9ghz, doesnt mean it actually is. that can be faked. 1944mhz will bench like 1944mhz, 1836mhz will bench like 1836mhz, and so on. if it benches like 1.7, 1.6, 1.5ghz, then its not 1.9ghz. sure benchmarks dont show real world use, but they do show what speed you are testing by their results. we know what range each speed should test at. fauxs' 1.9ghz doesnt test where 1.9ghz should test at, and faux has been caught before, on other devices, showing that the device is running at a higher speed when actually isnt.

Its becuase it throttles down when benching, its cause the freq cant stay that high the whole time without risking damaging the board so it throttles down to lower "safer" freq. On real cpu on a computer it has fan speeds to go higher when the temp is to high but that solution is not possible for mobile soc.
franco probably belives that 1.7 is the best possible OC since the throttling wont be that high. I would say that he is right but i prefer the stock speed and never mess with OC on mobile soc. But thats just me
More than often to much OC gives the opposite effect and makes the phone slower because of all the throttling.

IMO Trinity is probably best for overclocking, but even it can only go up to 1836 MHz. Also, there are risks to OC as well--which ranges from overheating to red light of death to your phone spontaneously combusting. Just letting you know

[REQUEST] Tegra GPU OC....

Hey everyone...I tell ya, I sure am enjoying all these awesome custom roms and kernels. Great job to all the developers here, putting in the blood, sweat, and tears for the advancement of the community, thank you so much. One feature that I saw in a Xoom build was the GPU overclocked, and while I'm sure it won't interest everyone, and there is probably only little gain to be had from it, I would love to have the option to oc the CPU and the GPU for the highest performance possible...please. Well I think that covers it unless someone else shares my desire to see this feature. Thanks for all your work and consideration XDA and have a great day.
if ur CPU OC than GPU too
Apparently not so on the Motorola Xoom as there are two versions of Tiamat 1.4.4... with and without GPU OC. Tiamat 1.4.4 Full Throttle

oc-ing the gpu doesnt get you anything... gpu is default 200mhz 2d with 300mhz in 3d and it can be uped to 250mhz 2d and 400mhz 3d but it cant be software controlled and it will eat more power...
and no oc-ing the cpu doesn't oc the gpu, its a separate part of the tegra2 processor
Hey Thor, thanks for joining the conversation. Based on what youve seen so far, how well are the tegra GPU cores being utilized? Suffice to say I've pulled off insane desktop GPU overclocks that showed almost nill gain with drivers that werent mature in which the GPU cores werent being loaded past 50% . I realize that the tegra is a horse of a different color, but isnt it still affected by the specific driver optimizations, hence the THD enhancements? Just out of curiosity as I very much trust your experience. I am still interested in trying it with definitive comparisons to follow...well about as definitive as synthetic benchmarks can be anyway.
I just saw that you have a new beta... Yay. I cant wait to give it a whirl.
I have been over locked for a little while. Max I have done is 1506 but it tends to be slightly unstable. I run 1400 now and haven't had any issues. biggest difference I notice is home screen transitions load fast and don't lag and programs load much quicker. there doesnt seem to be any games that will push the CPU hard so I don't notice much of a difference there.

I've had 1600mhz going strong with no instability, benchmark after benchmark, the only issue I've had is the device shutting down when left alone for too long, but I consider that a useful standard function. Otherwise 1600 performance has been rock solid. I decided to take it upon myself to take this girl apart' clean the CPU off, remove the thermal pad, and apply some as5....though the chip didnt really run very hot to begin with. Now until I have the option to go for 1800mhz, I'd like to see where the max threshold is for cpu/gpu oc.
I have mine overclocked also at 1600.. Runs very stable at this speed and benchmarks not too bad:

Can only the 3D Clocks be altered without touching 2D? If yes can you make such a version of the ........... that "nobody" knows anything about?

Very nice quadrant score man, I used to score alot higher until I updated to stock 3.1+ updates. It seems like the higher my OS version number gets, the lower my synthetic performance gets overall.

Wow!
Umm, what rom do you guys run for this? I'm on rooted and CWMd stock 3.1 rom. Can't find a OC kernel for it. Only one I can find is for ASUS based roms. I prefer to keep stock rom if it's possible.
ME: Asus A500 Iconia USA wifi only. HC 3.1

You should try richardtrip's kernel. His kernel is keep updating Very good performance and stability.
thats the kernel i am using o/c 1400 works very well. you can find it in the development thread.

Thanks! Works great. Do you feel the HoneyVillian rom runs faster with the v2.4 Kernel or about the same as stock Acer 3.1 HC rom with v2.4 Kernel?
So far I can keep stable at 1.5 after 2 hours of use. It's also slept for 30 mins and seems ok at that too.
Also what kind of Scaling do you guys use? Ondeman, Interactive? On my phone I use ondemand.

How are your benchmarks so high?

It's been about a year since any benchmarking threads have been created for the A500, and I'm interested to see how people are getting better performance.
I'm running Flexreaper v5 and I score around 6200 in AnTuTu. One other ROMs and other kernels I'm getting around 4300. However, the AnTuTu comparison charts show quite a few people scoring 7500+ with the A500.
How are people getting such high results?
Overclocking maybe?

Hoping for something a bit more specific. Kernel, ROM, CPU Frequency...
BTW - Mine is OCed to 1.5 GHz
Think I found one of the ROMs that's getting such high performance. I got the JB ROM from he would cannot be named, and this thing flies! 5600 in AnTuTu with no OC. Set GPU to 400 MHz and OC'ed CPU to 1.6 GHz, and that clocked in at 7225.

I'd be a little careful at 1.6. Runs a little unstable, and is only for benchmarks.

It looks like the new kernel allows clocking up to 1.68, so I have just left it at an even 1.6. I haven't run into any major instability so far (knock on wood), and I really like how smooth it is. I've finally been able to play Asphalt 7 smoothly (good way to blow off steam at work). Thanks, though.

Overclock TF300 2,0 GHhz

Hi, how can i overclock my tf300t (Clean rom 2.5 oveclock 1.6ghz) to 2.0 Ghz? i read something in the forum but there isn't any kind of guide, i want know if the tablet is stable with this frequency, and if i risk something.
thanks

Why would you need to overclock so high? Do you want it to explode! xD
Seriously though, would probably advise against it. It's like a whole 700/800 MHz higher than it's meant to run at stock. I'd say it would be very unstable, and probably wouldn't get very far battery-life-wise. 1.6GHz really not enough :/

1.6ghz is ok? or i'll risk something?
I did that speed already. But it is very very unstable. random reboots within 10 minutes of use. also the battery life is very low. and the whole tablet is to hot.
i only was using it to see how fast it could go. that was the max. i am at Cutom Rom - 07/10/2012 - [email protected] Edition V02 - The Ultra Fast Rom - based on last Asus Firmware 10.4.2.13 at this moment.
this is very stable. balanced speed is 1.3 and thats oke. Normal performance speed is 1.6 but i only use that when playing games. You dont need those high speeds for daily use.
If you have the financial means to buy a new tablet - you can try all the time to work on this frequency.
With 1,6ghz i'll risk to break the tablet?
i used 2.0ghz about a week daily use. But now im lowered it to 1.8ghz and it is stable my everyday use. and battery lenght is very good maybe better than stock (i made undervoltage, so cpu uses -50mv less power in any speed than normaly/stock )1.8ghz use 1150mv and lowest speed use 775 mv)

well, if you raise voltage up it may help, but i thing the problem is, that every tablet cpu is "diffrent" than other. This i mean, that these cpu is specsed in other speed than 1.6, 1,8 or 2.0ghz, and some invidiuals might work good in these higher speeds, some get randon reboots / freeze, or some of cpu:s dont even boot higher speeds. (i found out that when few people test my kernel, and it not even booted. And someone it will work fine.) This thing can "cross" by made kernel force cpu speed 1.0ghz at bootup (and i made this my kernel)
Also these tf300 tablet is manufactured atleast couple of diffrent cpu type /cpu id, so kernel have to had support all of these overclocking
It just like computers, some cpu can overclock higher than others, and if you go too high you need extra cooling, and in tablets, it is not possible, like normal pc's
*Most of this is my conclusion only, it may not be 100% accurate truth, but this how i see this thing. And if someone knows better etc, you can correct me *

Well im not home right now, so i dont have any 2.0ghz or 1,8ghz kernel with me, i have only 1.7ghz oc kernel, so you can test it if you want. But just like always, im not taking any responsibility, so test /use it with own risk. https://www.dropbox.com/s/vvmti4knwkeflde/Nixu_Kernel_OC_1700_v0.1_alpha.zip
i'm afraid now loool, what would happen exactly?
after flashing the kernel is locked to the screen asus, does not want to start

[Q] How to overclock gpu?

Hey!
My question is actually in the thread.. My brand new nexus 10 seems to be lagging in playing 3d games. That's why I was wondering if I could overclcock the house a bit to make the whole thing smoother Thanks a lot!

It's lagging due to thermal throttling not GPU speed overclocking may make it worse

PS if I remember right I think the thermal throttle point is kinda low on the nexus 10

Overclocking isn't going to help. Try it if you want but you're just going to end up with more lag.
You need to underclock the CPU, undervolt the CPU and GPU, and also slightly raise the thermal throttle temperature to about 90 (from the stock 80).

Try to under volt as much as you can and I find even 1.2ghz more than sufficient. 1.5ghz might make you throttle.
This Exynos chip is a serious powerhouse.

GPU Slow?

Hey XDA,
Not to sound like a nerd about benchmark scores, but testing using 3D Mark, my Graphics Score w/ a 600 Mhz overclock can't beat my Nexus 7 2013 at 487 Mhz.
I'm using Faux's Kernel, and I'm not sure what's wrong.

your phone probably cant hand the overclock properly. just because you set it to a number, doesnt mean that your device can perform at that number.
