I noticed on the black star rom I have the option to overclock gpu. I am wondering if it is a good idea

GPU overclocking carries risk, just as does an overclock of the CPU...
There are many variables that can affect device performance to the negative.
Overclock of the GPU can increase performance, but at a price. Heat, shortening of lifespan etc. are always a risk. not to mention battery life.
It's really your call, but exercise caution whenever you drive a chip beyond it's intended limits. Often times the voltage bleeding will counter any real gains.
A bit more reading is warranted.....g
You have misunderstandings or over clocking. Over clocking, or running a processor at a higher than recommended bus speed or with an increased multiplier, does not, in and of itself, use more power or generate more heat. It can lead to decreased stability. Overvolting is the act of increasing the voltage of said processor in an attempt to increase stability at the cost of increased heat generation, shortened battery life, and possible hardware damage.
I see these misunderstandings perpetuated constantly all over the internet, but take it from those of us who have been over-clocking for decades.

You can use this one safely.
The AOSP-based ROMs (AOKP, CyanogenMod, etc.) are already overclocked and nobody has had trouble.

As someone who first ported GPU oc support to our note, I'm sure this is not the case. If you know something I don't, could you link the source to your information?

Hmm, perhaps I'm mistaken but I only deduced that because the gpu performance matched the overclocked performance of Blackstar.

I don't think that anyone has developed a kernel that allows overclocking yet.
Haha not just yet, we need some kernel devs first

Can start once HTC releases the source packages which might be next week - could be a month - but we're at their mercy.
I'm really looking forward to seeing what overclock speeds we can get out of this.
I find it funny that we all want overclock for it tho. What can't we do with our phones right now that a 2ghz overclock will fix? ...I think I just like knowing its there.

Smartass scaling and undervolt go a long way for improved battery life.
Can any developer explain how it is possible to make a CPU faster and more effecient on battery, and why don't the manufacturers just do this before they sell it?
I understand the basics of how kernels work, but I wouldn't think you could safely double the speed of a processor while keeping it undervolted (coming from the d1)
Do they purposely underclock the kernel and used the same processors in "new" "faster" phones?

Very true. The Thunderbolt is my tenth Android phone since November 09, and in every single case, scaling and undervolting have made worlds of difference in battery life as well as speed. I'm sure that things won't be any different on the Thunderbolt. Of course, the other thing that makes a huge difference is not playing with it for hours on end. New toys always drain batteries pretty fast.

Part if it is what the industry calls "yield", that is just because they produce 10,000 1.5ghz cpu's in a batch, doesn't mean all 10,000 can run at 1.5ghz safely and stable, so manufacturers have to go with the fastest common speed In order to not waste those processesors that can't handle the full speed. Its the same thing with computers and videocards.

Definitely.
I have noticed so far that running SetCPU for just the scaling now is helping with my battery life, so that's at least a bit of awesome.
I downloaded nemisis's kernel 1200 OC and -50UV. it says the kernel is already overclocked. Does that mean i dont have to use setcpu? I never used any of these overclocked or undervolted kernels before. What instances do i need setcpu for?
You need to use setcpu. Its also useful for when u want to use different kernel governers or profiles under certain conditions.

ok so then the enderst special oc 1200 mhz uv by -50mv kernel is basically useless unless i use that app then (minus the UV)? also what are the chances im gunna fry my processor if i keep this overclock kernel for everyday use?
Edit: also how hot is too hot for a battery to get? aka whats a normal range? also after heavy use (like after playing angry birds or tank hero)?
The battery in our phone (cobalt li-on) should never go above 130c. At above 150c you going to get thermal runaway and have a dead or exploded battery.

The profiles are NOT compatible with Galaxy S phones, at least the Fascinate. Some may work for some people alright, but most people experience many different problems, I myself have problems with the profiles. I recommend against using them. Just use it for the governor/overclock.
Hello all!
I hope some of you like numbers as much as I do. I thought I should run my handset through a series of benchmarks in order to see just what the dev community has unlocked within this device.
Here we go:
Overclocked to 1.72 GHZ - Governor: Performance
Cubed Kernel 1.2.5
Genome ROM v2
BenchmarkPi:
Average of 5 - 337.4 ms
Best of 5 - 224 ms
Linpack:
Average of 5 - 463.059 MFLOPS
Best of 5 - 510.427 MFLOPS
ANTUTU:
Average of 5 - 18396
Best of 5 - 19270
Vellamo:
HTML5 -- 1737
Metal -- 636
Quadrant:
Average of 3 - 8131
Best of 3 - 8364
These results put the Droid DNA well ahead of pretty much all competition for the next few months. I imagine things will get even better once AOSP Roms make their way to this amazing device.
So - does anyone with a higher overclock have any stats? I would be interested in seeing how well this processor scales.
That quadrant seems low. I've gotten 8254 stock unrooted.

The benchmarks usually don't turn on all the cores. At least that's what I think because I turn all my cores on and all on the performance governor and I get around the 9500's at 1.83Ghz.
I've received over 9k quadrant and 500+ linpack with 1.5ghz. Strangely, powersave gave me better scores than performance (stock kernel)
On cubed kernel 1.5ghz performance = 587

I managed to break the mystical 10k marker on quadrant.
I've been more of a lurker, until now.
Anyway, this is with cores set at 1890x4, performance governor setting. Running senseless ROM.
I'd like to thank everyone on XDA for their work on android.

By the way, while my phone is stable on these settings it drains my battery too fast to be usable. I leave the cores set to 1890, but as long as I don't have the setting on "performance" I actually see decent battery life. My quadrant drops into the upper 9k's though without the governor set to performance.

Cheers for breaking 10k but why is your I/O score so low? (I've got 15k+ on the Note 2) Also was expecting the 3D score to be a lot higher on the DNA, kernel doesn't have support for GPU OC? IMO with those CPU / MEM and tweaking 11000-11500 should easily come

True. I could probably have a done a little more tweaking on the I/O score. The kernel used for this does support GPU OC, but I haven't found a tool that I feel comfortable using to OC the GPU yet. That and probably more realistically: I moved on to conquering other things once I managed the 10k score that was my goal.
I have SiyahKernel S3 v1.8.9 installed in my S3.
I have now installed " EvenMoreBatteryTweaksGovernor.zip " which is provided by gokhanmoral itself.
Now if i undervolt my phone to -25mV or -50mV will it affect my hardware ? as in my processor(all 4 cores)..will they have any negative effect ?

I read about this guide and after reading this guide i am ready to undervolt but the main thing comes that i already have installed siyah kernel battery saving tweak. so i have a concern that now, if i undervolt my device, will that affect my hardware as in processors ?
i am new to xda else would have posted direct here

I'm not sure what you mean by affect your processor. If you mean performance, no uv doesn't affect your performance unless you set it too low then it gets unstable and goes into bootloop. So you'll wish to tread carefully when going into over -75mv.
As for long-term damage on the phone, I heard many people say differently. Might wanna search and see for yourself. Personally don't really think it'd damage the hardware if you uv a little.

yes, with 'affect on processor' i meant that after a time period will it affect my hardware or not. my processor will be in good condition or not.

Benchmarks are unreliable ..
You have a custom rom and a custom kernel .
So why are you not asking the question in the relevant threads ???
jje
I never trusted benchmarks,but this one is so damn low.
Because I can ask almost everything I want in this thread.In rom/kernel thread just a part of the users answers,here a lot more people are watching so I might have extra chances xD.
Don't worry about benchmarks. Add long as real feel feels fast and not laggy then everything should be good

But it does!Whatever rom/kernel I use,after like 2-3 days of use it becomes laggy.

Ok there are still other things you can do. Maybe something is eating your cpu. Try using cpuspy or setcpu to see what clocks your using. If its at the highest clock all the time that could indicate a cpu hog.
See what processes are using those high clocks with top or another program run on the phone.
Most important though is to see what is actualy causing the low score, which part of the benchmark is causing low scores. Maybe IO or memory performance, cpu might be fine.
