A simple kernel created with the intent to get maximum battery with minimal sacrifice.
Kernel Features:
Undervolted - 800mV(-200mv from the stock 1000) for 245Mhz to 1000mV(-100mv from the stock 1100) for 806Mhz
Default Conservative governor (other stock governors included)
Ext4 Support
and assorted tweaks
Ramdisk Features:
Ro.secure=0 (ADB runs as root)
Removed CIQ daemon startup
Thanks: Bcnice20(great kernel, but different goal) and the rest of the kernel devs with git hubs

***This is a Sense based kernel, not ASOP***
FAQ
Q: Why does it boot sooooo slow? Is it stuck?
A: No, because of the conservative governor + undervolting it will boot slower, especially when rebuilding the dalvik cache.
Q: Does this kernel support overclocking?
A: No, as it isn't the goal of this kernel.
Q: How is the performance?
A: Should be comparable to stock.
Q: Why the lag when I unlock the phone?
A: The way the conservative governor is designed causes that delay as it rams up frequency. Once up, should be running smooth though.
Q: Can I change the default governor?
A: Yes, use a widget/app like SetCpu.
Known Issues
None so far, but potential errors with CIQ/IQ agents as CIQ fixes are not included in this kernel. Suggest removing anything in ROM with IQ in it.

{ 806400, PLL_2, 3, 0, 192000, 1000, VDD_RAW(1000) },
{ 0 }
};
bet battery life is AMAZING with this, too bad im running MIUI as of right now!
Will install over MikShift and post results thanks
Edit:finally got a full charge..will post in a bit

I've been attempting to flash this kernel over the NFX v2.0 ROM, but I can't seem to get it to take. Are there any special steps to do to install it?
Any help is appreciated. Thanks.

Yea never did report back..didn't notice much of a difference personally..guessing results will vary..actually it seemed my battery life got worse..but don't let me deter you from it cause it may work better for you

Check the wiki page
http://en.wikipedia.org/wiki/Texas_Instruments_OMAP#OMAP_4
Omap 4 tecnology.
You can see:
OMAP4430 PowerVR SGX540 @ 304 Mhz
OMAP4440 PowerVR SGX540 @ 384 MHz
OMAP4460 PowerVR SGX540 @ 384 MHz
OMAP4470 PowerVR SGX544 @ 384 MHz
And this last, the memory runs at 440Mhz, when the SGSII runs at 600Mhz, so the Optimus 3D? what frequency are runing the mems? ( if is 300Mhz, that dual chanel is wort? )
Anyway, i think this GPU can be overclocked to 384 Mhz? What do you think?
To overclock the o3d you need kernel that support overclocking. This kernel will come with CM7 rom

But i mean at GPU level, i read the sgx540 is hard to overclock...
Any way i can make my mod of the cam for the CM7 ? or is source close?
I think it's possible coz the same GPU existz in Galaxy S and o/c to 350Mhz and more with Talon kernel wasnt nothing special to make
Might be as easy as changing the source in
/drivers/gpu/pvr/omap4/sysconfig.h
#define VS_PRODUCT_NAME "OMAP4"
.......
#if defined(SGX_CLK_CORE_DIV5)
#if defined(CONFIG_SGX_REV110)
#define SYS_SGX_CLOCK_SPEED 304742400
#endif

apples and oranges comparing the two since only the cpu cores are the same.
hey guys. I like to overclock my phone. Im using Valhalla v1.3.2. GB 2.3.5.
Please tell me how to overclock my phone.

Here you go.
Btw don't overclock too much , it can be harmfull
using tegrak is great and easy, i am at 1.2 right now. i think up to 1.3 is pretty safe. here is a guide to under volt if you chose. overcloacking drains the battery much faster. http://forum.xda-developers.com/showthread.php?t=1294815
i found these settings to work best for me @ 1.2
Lv0- 1200mhz 1228 1095
Lv1- 800mhz 1093 1050
Lv2- 400 mhz 980 995
Lv3- 200mhz 877 988
Lv4- 100mhz 874 948
good luck
thanx guys
I think the highest dsexton702 ever tested it at was 1.6 GHz stable. Of course, you practically never need that much power, unless if you wanted your SGS4G to make breakfast.
Be careful when overlocking. It can damage your hardware when not done properly.
What is the best governor for Max performance?

performance = always max cpu frequency (Not for daily use!!!)
interactive provides a good performance.
Which governors are supported by your kernel?
Hands down
Thanks

thanks ..... :highfive:
I use the governor ondemand, and it works famously battery-wise.
