Hi everyone,
I'm a new user of this community and only yesterday I've downloaded the EchoeRom and AEL Kernel for my Samsung SM-G950F.
I've seen that the kernel is more customizable than others that I've tried but i have some trouble with Synapse.
It does work correctly and it is fantastic, I'm trying to get the best Antutu benchmark score possible but I can't overclock my GPU
If I set Gpu frequency over 572mhz when I start Antutu, it crashes after a bit seconds and I hate this.
Now I hope that anyone here can help me to set correctly synapse for overclocking my GPU (I've already tried to improve the voltage with some benefit effects but not enough).

while I realize that many people hate benchmarks the truth in my humble opinion as a windows hacker and android enthusiast is that benchmarks, run properly, can tell you a whole lot. there is some variances but usually that is from screen brightness settings, running at different core temps, background apps, widgets, and waving the accelerometer around like you just don't care lol. and you can say all you want to synthetic means nothing but the fact is even manufacturer's use benchmarks in their testing of new chips as well. just look at the current benchmarks from sd 600 vs sd 800 from qualcom. so I have decided to carefully benchmark every kernel myself to find what gives ME the best user expieriance. maybe it will help the dev's, maybe not. maybe it will help you, maybe you hate my dog and want to skin my cat.
a benchmark can tell you how well the kernel makes use of the hardware so for testing purposes I have used stock rom on all tests. I have set up my cold box for testing so that the cpu and gpu do not suffer and return quickly to normal and have set brightness at 50. testing is done stationary against the back of the cold box proped so that cool air flows over the systemboard. for testing purposes there is only the stock clock widget and micro cpu monitor and a few battery temp/sytem stats apps running. after each benchmark the tablet memory was swept. all benchmarks were run 3 times and the highest score given is used here unless there was a wild varient and then it was tracked down and all benches ran again. after contemplating it i ran some of these plugged up to the ac on my cold box and sometimes i forgot to plug it up. and some using debugging but i honestly doubt that had an effect. so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
im also not really comparing custom kernels to one another but I do to stock kernel, every last one of them are great and offer a lot of features you cant get with stock. all offer performance above stock if the proper settings are used and the overclocks are not to extreme for the framework. they are all also still works in progress so I think they will improve with the developers attention as time goes by. i started with stock kernel and ran antutu, quadrant, velimo, 3d mark ice storm, 3d mark ice storm extreme, basemark x, gfxbench 2.7.0 t-rex hd onscreen, gfx 2.7 egypt hd onscreen
stock kernel
stock ran well and i liked it, but i hated having to long press wifi to toggle and short press takes you to settings, wtf google?
edit.... so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
whatever flo 002 kernel
the kernel ran smooth and i liked it. i have the same complaints about it as i do stock. wtf google?
so on this kernel as you can see it functioned better than stock on every single benchmark. some were close but just a little better is...well...better.
jassy release 5 kernel
this kernel is set up to use an external kernel control app. it will not function worth a hill of beans without it in my testing. and even further than that it seems to not like trickster mod for me as it bench's higher with faux kernel control app paid version. real world expierance is good. fauxclock is set to 1.89 ghz CPU OC. cpu ondemand governor. snake charmer and mpdecision on. intelithermal at 60 and 80 respectfully. gpu at 487. gpu simple governor. fiops i/o at 512 read ahead. as you can see in cpu and gpu performance it face smashes stock kernel then kicks it while its down and makes it cry for momma. i dont know what the dude pasted into this kernel but i like it. jassy worked hard so we could have a full featured kernel that works well. release 6 = win, release 5 o yeah baby performance even ondemand. i could still kick this to performance governor lol
elementalx 0.7 kernel
settings with no external kernel control app.
1988 cpu overclock on each core. 487 gpu overclock. simple gpu governor. stock bus. stock voltage. no stw, dtw. the kernel ran well in real world performance. STW and DTW are awsome features by the way and i really like this kernel but didnt install them for testing purposes, one less potential irritation. as you can see it actually lost a bit from stock performance though in every benchmark except basemarkx and gfxbench 2.7 t rex. that tells me there is a problem with cpu performance in this kernel. also look at the cpu vs gpu in antutu vs stock kernel. so what i like this kernel and with lower clocks, dude it rocks. stw and dtw are wins.
elementalx 0.7
settings with no external control app.
1890 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus.stock voltage. no stw, no dtw. again the kernel ran well in real world performance but as you can see it took a serious hit in performance at this cpu clock setting. the gpu features continue to score high though
elementalx 0.7 kernel
settings with no external kernel control app.
1728 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus. stock voltage. no stw, dtw.
as usual really nice running and here the voltage values are more sane i guess. bested stock in every bench. i figure 1.9 ish before the poo poo hits the fan and performance benches go south rather than north. that seems about the same for the other kernels ive tested too. flar2 really has a winning kernel here with stw and dtw. highly recommend giving it a try
3flo v4 kernel
not testing this one yet as my boy doesn't even have the nexus 7 2013 but I tell ya, I got a good feeling about him. seems dedicated and excited.
Edit...he just got a mpdecision kernel booting and posting good scores but has a cores on touch problem for me. Very beta but it shows that even without a device you can build. Still got a good feeling about this one.
faux123 flo jb 4.3 001 kernel ulta
not coming. I can boot it and even run at highest settings but antutu ehh and im tired lol. maybe ill do it if the overclock structures are changed in some way but ehh not interested in this high on this chip.
faux123 flo jb 4.3 001 ES
settings. faux 123 kernel control paid version. 1.512 ghzcpu. mpdecision off. cpu governor ondemand. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400 and ondemand. fiops I/o 512 read ahead.
so here you can see again the same slight loss in gpu performance which lead to slightly lower scores than stock. cool kernel though and I do like intelli thermal so
faux123 flo jb 4.3 001 kernel mainline
settings in faux123 kernel control app paid version. 1.83 cpu OC. CPU Governor ondemand. intelliplug. mpdecision off. eco modeoff. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400. gpu governor ondemand. fiops I/o 512 read ahead.
so I found the kernel smooth in real world. I looked for my sweet spot and found it around 1.836-1.89 cpu. above that didn't really work out well for me. so in this great kernel the cpu benchmarks higher than stock but for one reason or other the gpu seems to bench lower than stock. all in all a great kernel and omg I love the idea of eco mode and I think with proper cpu governor and eco this kernel would rock some battery butt.
Tiny kernel
Coming soon
Hello everyone i'm relatively new to the world of governors,schedulers,oc,uv and so on....therefore i just wanted to ask what kind of setting do you use on your GT-I9505 for performance, battery life, a balanced profile? I played a bit by switching between different governors either on CPU and GPU and changed a bit in the I/O scheduler (never changed oc and uv things) but i still have a little bit of lag/freeze problems in some kind of 3D games and even a bit of overheating Any kind of help suggestion appreciated! My rom is a kushan rom v8.0 lite with the kernel bundled in it, the tweaking app i use is Stweaks. Sorry for my bad english, waiting for answers! :fingers-crossed:
hello guys, I made the root S7 edge Exynos version, and wanted to know how to set up the most of the interactive governor to improve performance, without too much worse battery, because with the performance governor the performances are excellent but it consumes too. thanks in advance to those who will help me. excuse me for my bad English.
I have to bump this. I am interested too. I installed super stock kernel that came with superman rom. And as I far I saw with synapse. There are tons and tons of possible adjustments. Around 20 or so governors. But some lead my device to be very instable. For instance Hyper I can not recommend. Instant crash and reboot.
As far the default setting is Interactive and it works well. Got like 12 hours with 3 hours Display on time. Performance is a bit lower in the moment as stock. But I have the bfq sqedular running. It's not super for Benchmarks but I hope it's good for video streaming.
i woundering this as well i got galaxy s7 930f running superstock kernel it has a lot of cpu profiles but non bearly works trying to select ,,,Barry allen profile fails ,,,,Intellimm fails,,,smartassv2 fails ,,,,
those that works are only electrodemand ,,, and interactive which as far as i know to close to original profile off the samsung own i think so idk how many tweaks there are in those
the profiles fails when i check A53 profile in synapse and A72 cpu profrile is it only the interactive cpu profile that you can use for those cpus since it says select interactive profile for those cpus ??
kinda confused a bit now .
Hello
Can you guys suggest me some good settings in kernel adiutor app for improving performance i'm using cm 12.1 ROM with telo kernel and if you know a better ROM and/or kernel please tell me
Better use phantom kernel. And look at the forums for good settings.
I'm using Phantom Kernel and I just like to adjusting the CPU and GPU clock based on my usage. On my regular setting I would like to set it up on 1,2Ghz CPU and 450Mhz GPU while using interactive governor. I don't know about other things you should checked the Phantom Kernel thread for more information and see the best that suit on you.
So I installed Kernel Adiutor to tweak the I/O performance and was kinda curious about the governors and all. I noticed that all 4 cores stay on at ALL times. Is this normal behaviour? Why is there no hotplugging? could it be implemented in a custom kernel?
Coming from a Snapdragon 801 which had quad custom cores, it used to have hotplugging to save battery. Thanks for answering if anyone knows

Click to expand...
Click to collapse
My only guess here is probably the Developer haven't add support for the new'er Snapdragon chip/s?
Been using Kernel Auditor for awhile and I see sd820 reads as single cluster where should 2 (big-LITTLE) . Well just a thought
ok that makes sense, do you know of a kernel tweaker which is updated to work with the new snapdragons by any chance?
I found an app that works, for anybody who is interested, EX Kernel manager works great with the big.LITTLE cores on the s820, happy tweaking!
I'm currently trying out the Interactive governor tweaks posted around the forums
