If I may ask, in terms of transplanting ICS to 2X what ROM would you regard as closest to "this would be a factory release?"
Does overclocking improve the response of the ROM? I'm finding what feels like an improvement on the stock ROM 20D with a kernel that gives me 1552 MHz.

I don't understand what you mean by transplanting, but I think you want a ROM that doesn't differ much from possible LG release!! Try the ROM with LG UI 3.0 here : http://forum.xda-developers.com/showthread.php?t=1508492
By overclocking, you provide higher voltage to processor which improves your performance, however decreases your cell's battery life! It can also cause excessive overheating issues and above safety level can fry your ROM. However, if you are Game addict or use heavy apps, overclocking is really a boon.

Hi friends,
i´ve a little question about the OC/UV features of some
kernels like damiangto etc.
I know that OC means to overclock the cpu to a higher
mhz rate. But i dont understand what undervolt means?
Can somebody explain that to me?
And i would like to know how the battery drain is.
Thx
its quite simple really, as the name suggets its reduces the voltage applied to the cpu. Less volts = less juice used = longer battery life.
Ok ive understood. But does that mean that when i oc my phone, that i can uv it so the batterylife will be the same as before?

Yes and no. Although everyone seems to be going on about battery benefits from undervolting I've yet to see conclusive proof it makes any difference. There is also quite a lot of trial and error involved in getting the phone stable with some undervolting.
I'd try it without undervolting.. see how stable it is and then try undervolting by 25mA each time on the higher frequencies before testing stability.
There's no guaranteed way of proving stability either, just try running lots of different apps etc and make sure it's not freezing or rebooting.
If I've made any gross errors of judgement feel free anyone to correct me

Hi. I just wonder about this.
Many times, when a new firmware comes out, after 2-3 days there are custom roms based on it, with tweaks (edited build.prop for example) and other speed mods.
Do they really improve speed? I mean seriously, if someone tests the 3-4 most known stable custom roms, based on same android version, and with the same kernel, also with the same apps on it, will be any noticeable difference in speed?
I see other devs releasing a rom after 3 days, and I can't explain what kind of tweaks could give more speed being stable at the same time.
Maybe custom roms are just modded/themed stock roms, and when there's a speed differenve it's because of the kernel inside.
Just being curious about that (also could make the choice of the rom itself easier...)
Any opinion? From your experience at least.

A mixture of both .

definately a mixture of both. They both make huge improvments over stock. in my opinion anyway
probaby karnel or speed
some costum rome improve your phone speed or karnel speed. especially visuality.

I don't need to improve my phone's karnel speed, it gets enough girls as it is.
However in my experience speed improvement and the smoothness that comes with it are mainly the process of the kernel as that controls the interaction between android and the hardware, where most performance bottlenecks happen. The ROM itself adds functionality, appearence and most important of all...stability.
At least so it appears to me.

I partially agree. I mean, if we assume stock roms are stable, custom roms can;t be more stable.
So, they provide some speed, maybe because there are not so many system apps inside, and mostly they provide some nice mods (visual and functional).
Hi,
Just wanna know people's experiences with roms and battery life?
Which one is the best ? This is subjective but generally speaking which one stands out.
Also, does Froyo have the vodoo battery life - where it just disappearrs? Had this once on mine. GB is better ?
Cheers
I have used stock Froyo and stock Gingerbread, and in my opinion Gingerbred is more better than Froyo in many things.

Overcome Gold , as Far its very good with battery life and its much better than the stock gingerbread
Stock is better because the latest oc has overclock which seems to make my gt warmer.As electronics is my profession I know that heat is a major stress factor for components.
I also share the same opinion as thepitbull regarding overclocking.
You can also use setcpu to underclock but for me I'd rather stick to simpler means.

In case you do undervolt only, that should help you battery life?
I'm using Overcome RC1, Gingerbread, and I need to reset the battery and the battery stats, since battery life seems nearly only 25% of stock.
However I know that once this is done, the batterylife is very good.
I will check out beta3 Honeycomb tonight or tomorrow when it gets released, was quite happy with the batterylife of HC Beta 2
Hi there!
I'm new to the Optimus 2x rom stuff. I used a Galaxy Spica before, which I rooted and installed some nice roms on.
On my LG it seems that the custom-roms I chose so far make no difference in speed compared to the stock rom.
Quadrantscore: ~2200 with WIUI 2.5.25 Stable (GB) and ETaNa STOCK_LITE 2.6.32 which is (according to Quadrant) below the O2X.
In some rom-threads I see scores of about 4000-6000 how do I reach that? Did I do something wrong?
greetings, and thanks for your tips
reijin
//PS.: I'm aware, that those scores are not a prefect representation of how the overall experience with a Rom is, but I'd like to know. At least the new Rom feels way better then the original stock rom.
Yeah it's a bit strange. I'm using cm7 on mine, the general performance is really nice and fast no complaints from me but running quadrant benchmark I get scores of around 2200-2300. My friends o2x hits scores closer to 3000 on the same rom. Both using temasek's kernel too.

I only have experience with ICS ROMs and kernels, but I can testify I've consistently had quadrant scores >4000. It's a complicated mix of the hardware you have (no two o2x's are the same), whether your kernel allows overclock, how optimized the io is, etc.
Sent from my LG-SU660 using xda premium
try to use antutu benchmark and see your score. and you're using stock lite which is 1.0ghz the clock. if you want to get higher score try HOC lite, and use OC/UV programs to control your clock cpu. i use pimp my cpu profile i set:
- daily freq: 216-1015MHZ.
- bench freq (like antutu,quardrant, necore, vellamo, and so on): 216-1418MHZ.
- and so on, what ever profile you want
You used spica and you don't know this basics?
Spica's angry anboys can tell you.
I can say that high quadrant scores can be resulted when IO rate is very high. You can cheat quadrant at it will think IO rate is high but it won't make phone a formula 1.
Use app2ad or something that uses ext partition and then run quadrant.
I am afraid y used spica and didn't know it.

With CM9 Harsh kernel i have in Quadrant 3200 points
There's something I don't get it. I have been playing around with CM10 (JB) and Minimoto (GB). Using Vellamo scores as indicator, the performance in JB is much faster than GB. HTML5 scores of 1400 (JB) vs 600 (GB) and CPU scores of 400 (JB) vs 370 (GB). However, that does not translate into user experience.
CM10 is supposed to fast and optimized for speed, but I am getting serious lag. OS is not very responsive to touches, apps take a good one second longer to open than in Minimoto which is GB-based. Isn't ICS and JB supposed to have additional hardware acceleration that GB does not... so why is Minimoto outperforming CM10? I also frequently manipulate spreadsheets on my phone, and the scrolling performance is way smoother on Minimoto than on CM10. What's going on here?
The reason is RAM. There isn't enough really unless you set it to strict memory management.

It's not the RAM. Samsung Galaxy S has the same amount of RAM as the Droid 3, and it's more responsive...
Kexec Ducati is not memory efficient.

^ what he said, kernel just isn't completely optimized for our phones yet.
All that new hardware acceleration takes code to make it work
Something quick u can try tho:
Depending on what kexec kernel compile your using you can try switching cpu governor from interactive to ondemand or one of the other choices.
Certain builds have it disabled, otherwise its set as default
interactive is buggy for some reason and causes crashes/some slowness.
I know it helped me a bit, even though it uses a bit more battery.

Thanks, maybe I'll dual boot/flash a CM10 and try full performance, but with battery issues and camera issues, I don't see how CM10 is stable enough for daily usage.
What's the point of running ICS/JB if the drivers are not optimized and/or if you need to force it at full performance mode to get acceptable performance? Isn't moving from GB -> ICS/JB about performance improvements?
