Root Dirrk's D01 overclocking kernels with lagfix

[saps]

And yes everyone, it's fine to flash any oc'd or other kernel that has voodoo over any other kernel that has voodoo

As long as its the same revision of voodoo.
If they revise the "formula" again to a voodoo v.3 this might not be true

JT's 1200 came out on saturday in irc right before 12 AM, right after he released voodoo 1ghz to the public. A few of us got it then and everyone's been fine on it except one guy who knew his phone can't handle 1200 at all.

Great stuff thanks. Damn maybe I should get on irc
Since you are on it more than me can you give any update on the progress of the 1.4Ghz kernel

 

[Gitykins]

Well that's alllll up to Dirrk since jt doesn't believe in anything higher, and Dirrk hasn't been on for a while.

The only way would be that thing I posted on xda about the voltages that seems really complicated O_O

 

[zero_one]

installed the 1.2GHz Voodoo. It's noticeably faster, but it constantly freezes (requiring battery pull) while running the 3d section of quadrant.

The Speed Pi is also consistently around 550ms.

 

[Gitykins]

Dirrk or JT?

 

[zero_one]

JT's.

now I'm having freezes just using the phone, going into the messaging app. =/

Thanks for the info. Damn that kinda sucks. I prefer jt's work. Does he just not believe the cpu can run at 1.4?

 

[Gitykins]

No, he says it can but that he's not interested at running it higher than 1.2

 

[saps]

No, he says it can but that he's not interested at running it higher than 1.2

I suppose I can't complain since he's done so much already; even if I dont agree with his stance. I suppose if Im not going to step up and do it myself [which Im not] I have no room to complain

Thats one thing I can say for dirrks D01 kernel, I haven't had the first hang up or reboot. The lv kernel is of course stable since it rarely exceeds 800mhz but it is nice to see an undervolted kernel running such a wide dynamic range as 100mhz to 1200mhz 100% stable. My old lg ally had trouble maintaining a 250mhz to 600mhz range (600 was stock) amd would reboot/kernel panic at 629mhz ! lol

 

[zero_one]

Geez, had a freeze just going through the gallery. Pushing JT's 1.2 makes it really unstable, I'm going back to stock.

 

[zero_one]

Honestly, in retrospect, the phone feels MUCH more stable at the stock 0.2 Voodoo than OC'd on JT's 1.2 GHz Voodoo (this is of course in my experience). I think I was just attracted to the number "1.2" and got excited, but testing it showed otherwise. I put the OC'd kernel through some stability and speed tests and it was noticeably SLOWER than than of just stock voodoo (I'm back on stock now and tested it in all the places that the OC'd kernel froze or slowed down).

I'm gonna stick with stock until these OC'd kernels are ROCK solid from now on.. it just depresses me to have to pull the battery. This of course is in no way meant to insult any of the excellent work that the devs have been doing, but rather to point out what I learned from my experience.

Yeah well I think we showed it was a misnomer to call it a 1200. The range truly was 100-800Mhz so yeah stability was expected. I mean there are and Im sure will be more undervolted kernals for those chasing battery life. Besides many will argue and I would almost confirm that voodoo does more for overall system performance than OCing. So if you have the stock Ghz speed but add voodoo FS and then undervolt it its going to be attractive to a lot of people.
It does seem not every hummingbird is comfortable at 1.2 as well; though most are

Yeah please report back. Overall, most will find the 1Ghz w/voodoo is going to be more than adequate and quite a step up from the stock phone

the standard voltage variant does run at 1200Mhz though...and it is also rock solid for me

Thats a good report. Have you already shared all your results/numbers? I've been here and at xda all day off and on I cannot remember. I mean you got Linpack above 9.5 and 1800+Quadrant?

 

[Gitykins]

.

 

[saps]

Nice, those numbers are consistent JT's 1.2 voodoo which if memory serves is what you're running. Man long day and I cant remember

 

[ktez]

Hope this doesn't sound like a dumb question, but am I correct in thinking the LV kernels are better on battery life? And the SV are a little faster, but do they drain the battery faster?

i had a rough night, not the kernels fault, but i wanted to start over clean because i figured i had done too much with the phone before now....which was affecting my performance, because i had done the original lagfix and then removed, and lots of apps had been installed and removed, but they left behind a bunch of crap........

after a bunch of help in irc channel i finally got it sorted i think.....so for now i am only running root, for adw launcher and a couple other apps, no lagfixes or oc'ing until we get 2.2 and things are more sorted out and stable

the latest lagfix is a bitch btw, you can easily mess up trying to go back the other way....to sum it up, a nandroid backup cannot undo the ext4 changes the voodoo lagfix made...and even after doing a full Odin restore, system, kernel, recovery, PIT and CWM recovery and many clearing of caches and data reboots....black screens...what appeared to be a very expensive paperweight is finally back to stock...rooted but back to stock...where it will stay a while

you cannot just flash a stock kernel and whatnot back over these new oc/lagfix kernels, you'll end up like i was, with a phone that would not even turn on, blackness......in IRC, in desperation

 

[saps]

jamesnmandy I hear ya. Thats where I was early sunday morning. Its why I imposed my own 24 hour wait on new kernel installations...

...but even I broke down. I installed awhile back. I did run into the same freezing/hanging issue that someone above did in Quadrant. However, all else seems ok. Im going to try other kernals out now since I only have jt's 1.2voodoo. I will say I can make it thru Quadrant at 800Mhz with a score just under 1500, kinda like jamesnmandy was getting yesterday. My linpack is off the charts though over 9.9.
At the end of the day if I have complete stability minus completing Quadrant thats a decent compromise for me. I have yet to see a problem otherwise. I set SetCPU to performance [locking the cpu at 1200] and ran test after test of Speed Pi and Benchmark Pi and no locks up or hangs.

*edit* spoke to soon and crused myself. I had a lock-up using the xda app of all things, there's some irony there Im sure.

I will probably spend some time trying out other kernels tonight. I will report findings as they merit mention

 

[saps]

Hope this doesn't sound like a dumb question, but am I correct in thinking the LV kernels are better on battery life? And the SV are a little faster, but do they drain the battery faster?

Yes precisely.
I asked Dirrk what his voltages are and he was kind enough to share the values:
lv1000 & 1100 is at 1225mv
lv1200 is at 1250mv

Sv 1100 is at 1275
Sv 1200 is at 1300

This confirms my suspicions. The Epic guys proved the hummingbird can run 1.2Ghz on 1250mV, its just not a guarantee for each and every cpu.
Again to remind all, out of the box the SF runs 1Ghz at 1300mV. So any of the LowVoltage kernels should give a moderate increase in battery life, especially those 1000 and 1100 models.
I started with jt's1200 and now Im going to work back, probably try jt's 1000 before moving on to some of Dirrk's.
If you can run the lv1200 that is going to be the best option as you will get extra speed and better battery life. It does seem not every cpu can handle the low voltage. I have not tried it yet but rest assured I will get to it

Lemme guess the one where you are going up the stairs right? I found the same thing

JT's.

I had a freeze while using the xda app, how ironic is that

Geez, had a freeze just going through the gallery. Pushing JT's 1.2 makes it really unstable, I'm going back to stock.

Yeah I mean we talked about this before the voodoo does most of the improvement. And between voodoo or an OC, the voodoo is the preferred choice of most performance boosts. Now both is preferred at least for me but. There isnt anything wrong with running just 1Ghz with voodoo. In fact you might try grabbing one of Dirrk's LowVoltage models. That way you'd get superior battery life and the extra performance

 

[saps]

Not to get into too much of an e-penis show but this Linpack is the highest I've seen or even heard of from a SF so:

 

[saps]

OK so jt's 1Ghzvoodoo checks out error free. I threw everything I had at it, 0 locks or freezes. 10 consecutive Quarant runs, 5 straight minutes of Speed Pi, NeoCore, the SetCPU stress Test, video playback, you tube you name it I probably did it.


BTW if I didnt say it yet I love the bootanimation jt picked. Just about worth it just for that change. I would say anyone who wants a nice boost and a fun new bootscreen can safely go with jt's 1000.
