Overclocking?

Hello,
I've seached as much as i can and i guess as a rookie i am still having a hard time understanding all of the benifits of overclocking other than speed. I am basically Autonootered 1.01, would it do me any good? If so which Kernel should i go with or is this for the more advanced?

Do you know what overclocking is? If not read this: http://en.wikipedia.org/wiki/Overclocking
After reading that you still don't understand how OCing will benefit you, and the dangers of it, I don't know what else to say.

As of 24 hours ago I purchased a nook color rooted it, applied the 1.1 update zip, and overclocked the nook Using the 1.1 ghz kernel honestly I haven't notice any speed increases because I did everything straight out the box but quadrant scores are very high

There are no other benefits of overclocking other than speed. That's the purpose of overclocking. Stability and battery life is usually the trade off. With the kernels from http://forum.xda-developers.com/showthread.php?t=925451 I would say the risk of instability is very low. Especially since there are different levels of overclocking with those kernels. As for battery life, it doesn't feel like my battery is draining any quicker but I haven't compared my run time before and after overclocking.
I have had my NC since just after Xmas and I can tell you by my own experience that things were noticeably quicker when I went from an Autonootered 1.0.1 stock (800 MHz) to 1.1 GHz overclock. Before I overclocked I had been running stock for at 2-3 weeks. I mostly noticed the speed increase loading eBooks and websites (using Dolphin HD).
Personally, I would just go and try the 1.1 GHz kernel (kernel-1100mhz-omap3630.zip) within the link above. There a lot of people running on that kernel, including myself, that I don't hesitate recommending it. However, I would download all the kernels so you have them all handy just in case so you can flash to another kernel, such as stock, if for some bizarre reason you can't boot or have stability problems with the 1.1 GHz overclock.

As I stated I wasnt sure of any other benifits, other than speed with overclocking. But I do understand what it is. The majority of the threads i found that people were discussing it were either Froyo or more advanced than autonootered. Just trying to do my homework.
Thanks for the help guys.

[Q] Linpack for android..am i lacking?

Ok so i flash theses beautiful roms and now ive tried some testing and currently on my captivate i ran the "linpack for andoid" app and it states:
MFLOPS: 13.982
time: 6.0
Norm Res:5.68
Precision: Inaccurate result
ok so i looked at the top 10 section ounder my phone and their MFLOPS is between 20-50 MFLOPS...So do i need some tweaking?..I mean the phone is good , Rom is awesome...any thoughts?
Captivate 1007
Phoenix 5.2 (2.2.1 JS5)
Speedmod i897 500hz k13c
UGJK4
Lagfix enabled
(r) Tweaks enabled

I wouldn't worry about it. First, your test said inaccurate results, so try running it a few times, though you probably won't get much more out of it. Secondly, most people believe these benchmarks are a load of BS, and I would trends to agree. If the ROM feels snappier and works smoother than stock for you, there really isn't any use in the benchmark scores. I'm running Serendipity 5.11 with the same kernel as you, and I find my scores are in the low 14's- which, as is for you, seems slow compared to the online results. However, my phone supposedly blows the other results out of the water in the Quadrant Standard benchmark, regularly achieving scores over 1500, and I imagine yours would perform similarly, so no, I wouldn't worry at all.
Overall, most of the roms on here achieve faster performance along with better battery life compared to a stock cappy. I suggest trying out as many roms as possible to find the one that fits you best, as everybody has different tastes, and each rom behaves differently for everybody.
Personally, I think Serendipity is something you should try, as it looks friggen sweet as is, and even better IMO with some tweaks. I changed the battery indicator to the android dude, the font to Armani, and use launcher pro over the base rom. Altogether, my phone is super slick and snappy. Oh yeah, it also accesses HSPA networks, so downloads are way quicker than stock (pretty sure your current rom does too).

that's about right, repeated tests should get you 14+. it does say inacurate so i dont think you have a problem, just a process running somewhere. the hummingbird lacks a bit in this area and snapdragons excel only in this area. i know it is weird that the nexus one and droid incredible smoke this phone in linpack but it is hardly a thorough benchmark. run quadrant on CM7 when it comes out and see what the hardware is really doing without the samsung influence. despite the low mflops you will see good scores across the board.

Thanks alot for the input everyone...jus curious how gen-pop was adding up... but who cares about the numbers i suppose when my phone is soo [email protected]## cool hahha

Just for the record, I'm on stock Froyo, With no SpeedMod, but with voodoo lagfix and I got better benchmark, linpack and quadrant scores than I did with a custom rom and Speedmod kernel before. Add to that the stability of a native ROM and kernel, and I think you know what I am saying here...

[Q] Benefits of OC/UV

What are the benefits of OC/UV (particularly for CM7)?
I know of improved performance due to OC, but what does UV do in regards to performance. Also, how does an OC/UV kernel compare to one without the option?

your processor doesn't need as much voltage as the stock settings--undervolting lets you save battery
personally i want to know.. do you have to UV to OC?

You can do either or both but don't have to do both. At some point UVing will cause a crash. Right before that point it can cause performance issues. See the link below for instructions on how to find an optimal UV level to maximize battery savings and performance.
http://forum.xda-developers.com/showpost.php?p=10936691&postcount=1102
OCing improves speed but can also cause stability issues. For a captivate this usually isn't a problem until you get past 1.2 ghz. After that, it depends on the kernel but I have yet to find a kernel that is completely stable past 1.2 ghz under stressful conditions. Samsung designed the processor to handle 1.2 ghz and in theory it can go up to at least 1.6.

Like everyone before me has said, OC will make your processor work more (which will eat up more battery, and send the temps a bit higher).
UV is a way to "fix" that problem by controlling the voltage used by each Mhz/Ghz range. The mini guide that QuarkGluonSoup posted is a great way to start off.
Most Captivates start have random errors past 1.2Ghz, but the highest I've seen (stable) are 1.4Ghz.

Odd as it sounds, my battery life on CM7 is close to 50% better when it is OC'ed to 1.2 ghz and UV'ed than it was on the froyo ROMs under the same conditions.

That really is odd :S I think I'll try it myself.

Benchmarksssssssss!!!

Hi guys!
can you post your SGS configuration and tell us how do you score with Quadrant Benchmark?
mine is that:
SGS i9000m
kernel speedmod 13c - rom ZeroGingerMIUI with no OC Lagfix ---> 1800
kernel speedmod 13c - rom ZeroGingerMIUI with 1.2ghz OC Lagfix---> 2100
kernel super optimized - rom ZeroGingerMIUI with 1.2ghz OC Lagfix--->2350
kernel hacked Supercurio for GingerBread - rom Ultibread v1.4 Lagfix(no system) --->2000
yes, i'm a bench_maniac!

Stock I9000 XXJVK --> ~awesome scoreon my user experience benchmark.

Awesome... no words to describe!

Quadrant doesn't reflect real life performance at all. I used to get 2200+ with a lagfix on 2.1 but it was no where close to the real life performance of what I experience now on 2.3.3 JVK with no lagfix where Quadrant score is just 1020 .

Nice

quadrant doesn't reflect the actual user performance/experience because in the past i've had high quadrant scores but poor user experience.
but as the versions change (i.e eclair>froyo>gingerbread) i get lower scores but better user performance.

Agree my user experience benchmark is also off the scale .
Quadrant crap as always .
Why dont you post all these benchmark quadrant posts in the same place if you want to compare size.
jje

1200 on miui

Mine is scoring "awesome" too in user experience!

I personally think this thread should be removed I'm afraid.. For starters, there are a billion other quadrant threads, and nobody has F***king bothered, as mentioned to collate the values into a table. Also, nothing is worse than breeding a culture of people who believe that Quadrant accurately measures the mobile performance for all workloads.

I agree with Ausy that this kind of thread is not of much practical use. I run Quadrant weekly, but only to compare my phone to itself as a diagnostic. If the Q score changes radically, I try to find out why. I also use it to compare ROMs.
However, I don't see that the benchmark scores of two different phones will tell you anything of much value when you compare them.

[Q] Fastest Captivate 2.3 Rom?

Which of the current 2.3 ROMs is considered the fastest/most responsive? Or which ROM would be considered the fastest based on the mods & tweaks used by the developers? I'm not to versed in the technical side of things to discern which tweaks/mods/kernels/etc give way to the most stability, speed, and response and would like the community's opinions on the matter.

Probably CM7, I just started using it and there is never any lag. I haven't even OC'd it yet. This also comes with the price of having to live off a wall charger though.

If you mean fastest in clock speeds, then thats a balance betwen rawr clock and how much battery life you can get out of it. Keep in mind these phones clock easily 1.2ghz-1.3ghz no issues past that you need to increase the voltage. So you can in theory get 1.6ghz-1.8ghz but you will live next to a charger. If you mean fastest on how it feels Id have to say Continuum moved awesome few months back (haven't used it in a while) Atomic Fusion if the ext4 version comes out. But there you should just test them out.
On a side not if you want to OC your phone and not have to pay for the oc app, then Id suggest you stick to I9000 ports or AOSP's like CM7 or MIUI. Native roms like Cognition 5, Atomic Fusion and Nuclear Fusion need Tegrak for OC/UV.

Which of the I9000s seem to run the fastest/smoothest? I've been looking at Dlev and Darky but how does Apex/Symply GS II/Mosaic/Sensation compare?

I actually read in the Glitch kernel thread that when overclocking, higher voltages doesn't always mean more stability. I'm OC'd at 1.5ghz right now really stable and I was UV'd at -50mv but I just dropped it to -75mv to see if its stable there. I'll keep dropping it till I have issues.
Oh yeah, and CM7's battery life has got WAY better over time, so I'm not having to worry about charging all the time either.

From my experience to maintain a stable phone i over volt the "step" that's overclocked, and then undervolt the other "steps". Im by no means a expert nor is there a full proof way to do it. Each phone kinda reacts differently on the overclocking past 1.2-1.3ghz.

Which of the I9000 roms should theoretically run faster due to the tweaks/mods used by the developers without the need to overclock?

There if no need to overclock for daily use. Only if you are playing very demanding games. And only during those games.
As for fastest rom....have a search this question gets asked a lot with always the same answer and result:
There is no best rom, all phones are different as well as tastes, what's best for me on my device may not be on yours. Flash and try a few and make you own decision...

CM7 is fastest but Display and Sound quality is not as good as stock ROM .

Before school started for me and i couldnt access a charger when i wanted to, i used MIUI at a stable 1.6 GHz ALL of the time with odemand govenor and i got like 18 hours with moderate use, on Glitch V12! And you dont need to overvolt for higher speeds i have tested it and its better to undervolt higher clocks, i get better battery and performance!

For the 10th time Each phone reacts differently to Overclocking. There is no sure way to get it OC/Uv. On my phone past 1.2ghz i need to over volt.

Well i ran 1.6 GHz undervolted at ever clock speed fine, had better performance than over volting, so its different
