[EVO 4G Android Development] EtherealRemnant:
It wasn't just stably hit either... I could run the phone at 1.2GHz for hours without a force close or reboot... It takes about 10 minutes on this kernel with it locked at 1152 before it reboots.
[EVO 4G Android Development] netarchy:
Hrmm, that makes me wonder if it's being caused by the working hdmi-out. The only difference between 3.6.4 and 3.7.x was making hdmi-out work with the fps fix, the OC stuff between the two kernels wasn't touched.

This is all good feedback.

Just out of curiosity, are you using a min of 128 or a min of 245?
[EVO 4G Android Development] EtherealRemnant:
I'm using a min of 245... but even when locking min and max at 1152 it does the same thing. In my case, I've had the reboots, freezes, and FCs since I started using your kernels and overclocking them. I'm guessing its just not enough voltage.
[EVO 4G Android Development] netarchy:
Maybe, but given that the voltage values haven't changed between 3.6.4 and 3.7.x , yet apparently the max stable clock may have, says that more could be involved.

Plus, more voltage = more battery drain ;D
[EVO 4G Android Development] funcrusher:
3.7.3c w/ oc bit my battery pretty hard. Changed over to non-oc and I'm down to 44% after 8 hours.

I used my phone more than I have since I've had it, so I'm going to go through another cycle. My stock/tweaked baked snack kernel setup would normally get me 24 hours.
[EVO 4G Android Development] EtherealRemnant:
Well I have an Epson screen so I started using your kernel before 3.6.4... I don't remember exactly when overclocking was added but I was using fflokes' since his kernel was built off godmode for awhile and unlocked the Epson screen... albeit with tearing...

[EVO 4G Android Development] tommy96814:
is there a froyo version or works on both?
[EVO 4G Android Development] mawst95:
I use 245mhz as well. I used every version between 3.6.4 and 3.7.3c with the same settings 245/1.15. 3.7.3c rebooted on me once after about a day (didn't freeze though). The intermediate versions between 3.6.4 and 3.7.3c -- I never had freeze-ups or reboots but I never used them long enough though. 3.6.4 I've used the longest and never had any issues. It qualitatively has given me the best performance and I don't use HDMI so I've stuck with it. After my reboot with 3.7.3c I hard reset (or the Android equivalent). An n=1 isn't enough to really say that 3.7.3c was the issue, but I wanted to report it...

I've been on the stock OTA rom throughout. HW003 Nova

Well I did a did a nand restore to the the original state with dc. It worked fine, then I went into fresh again.. All seemed good. Then I tried 3.7.3b, 3.7.3c, and 3.7.3c for fresh, still get the problem
[EVO 4G Android Development] JackDaniels7:
how to i actually test the multitouch aspect
[EVO 4G Android Development] PhantomApollyon:
245 has been my min since the start and the only setcpu change I made was to bump down to 1113mhz because of the reboots happening at 1152

I also would like to go on record saying that I'm perfectly fine taking the hit in clock speed to have everything working right, you've done an amazing job with these kernels. :)

EDIT: also just to confirm, I flashed 3.6.4 and its stable at 1152mhz and then flashed ffolkes and it has no issues at 1200mhz...so its definitely not in my head :D

I'm averaging 52 fps when running fps2d, but I'm only averaging 27.3 fps on neo-core. Wtf?
[EVO 4G Android Development] netarchy:
Even the nexus one averages around 27 in neocore (same resolution, same cpu/gpu, no cap). Neocore pushes the gpu to its limits, the bottleneck in this case being fill rate.

Just because the cap on fps is higher doesn't automatically mean everything is going to hit higher ;D.

That'd be like turning vsync off on a pc and wondering why crysis still doesn't break 30fps on a particular graphics card.
[EVO 4G Android Development] PhantomApollyon:
haha, Crysis was one of the most poorly coded games in terms of ability to produce a descent frame rate, It was something of a feat to get 60fps on that game :D
[EVO 4G Android Development] astro004:
I've been reading posts about the overclocked and non-overclocked kernals. However, I cannot seem to distinguish between the two in the kernal download section on the primary page.
[EVO 4G Android Development] PhantomApollyon:
Its not so much that the kernels ARE the over clocking, but that they ALLOW for it via something like setCPU.
[EVO 4G Android Development] PeoplesHelper:
Lets see if i can help, first they all are overclocking kernels on that page. the general kernel can be use on most roms ,I use that one on the stock rooted rom works great. then there is damage whom makes specials roms that that kernel works better for then fresh has his. Hope that help.

Great mod, works perfectly on my Evo. Getting 50+fps consistently. Thanks!

Reboots

I was at dinner last night and my phone went into a continual reboot cycle. Each time it would reboot it would start loading all of my widgets but said I had no service. I let it do this three times then tried to power off with no luck. Finally, I pulled the battery and restarted and all was good again. I then noticed that my market had changed to say Sprint as discussed in other threads. I also lost the higher FPS I was getting.

This morning, I reflashed the 3.7.3c kernel and my FPS are back into the 50's. Do you think my reboots last night were caused by the kernel or possibly by the changes to the marketplace? I am running Unrevoked 3 with the stock ROM and this kernel.

Thanks!
[EVO 4G Android Development] 12MaNy:
Yeah, that and neo-core is more of a 3D graphics + sound benchmark. Sorry, I was a bit drunk last night.
[EVO 4G Android Development] Rippley05:
I orginally thought the OC kernal for nova screens using DCs rom was killing my battery faster...but it definitely isn't.

I have SetCpu installed but I put it back on 998400 which I htink is the default for snapdragon, I really don't know WTF I'm doing when it comes to OC'c kernals or whatever..

The kernal for DC seems to be pretty great, its only letting me getting 42-44 FPS tho and I can't notice any difference from DCs stock kernal. If anyone is getting better results please chime in and tell me what I may be able to do!@

Thanks again for the custom Kernal, 42-44 is better than 30 even if I don't notice it right away!
[EVO 4G Android Development] SilverZero:
Quick question: Do I flash my custom ROM first, or the kernel?
[EVO 4G Android Development] netarchy:
Rom first, then kernel
[EVO 4G Android Development] netarchy:
Try changing your performance profile in dconfig, I'm guessing it's probably set to something like battery saver. This sets up defaults that tend to increase battery life, at the cost of a bit of performance.
[EVO 4G Android Development] SilverZero:
Perfect, thanks for the quick reply! I just flashed Fresh 1.0.1 and the Fresh-compatible kernel (3.7.3c). Am I just imagining things, or is the scrolling in the settings menu super-smooth and fast?

I had a similar issue and the reflash seems to have corrected it for now...right now i'm getting about 54fps avg...
[EVO 4G Android Development] Fyahstarter:
Quick question...If I want to try out another kernel, can I install one over the other without any ill effect or do I have to wipe and start over?
[EVO 4G Android Development] sag7392:
Install right over it...I just did with 3 different kernels.
[EVO 4G Android Development] tehpsyc:
I have a quick question. I've read that the latest cyanogen rom fixes the bluetooth stack issue with HTC sense. I don't know if this is something that lies in the kernel or the rom itself, but if its part of the kernel would it be possible to implement this into this kernel?

Same here. And swype is all over the place. Something is messed up.

Hmmm. My fps has been around 53 since 3.7.3c came out and my Swype works great. I am using Fresh Evo 1.0.1 without SetCPU.
[EVO 4G Android Development] THunDA:
So there's certain sweet spots where the voltage changes?
[EVO 4G Android Development] freeza:
So using 128, 245, 460 MHz uses the same battery life?
[EVO 4G Android Development] OneStepAhead:
If the voltage changes above 460, then it would stand to reason that clocking below that would actually use more battery, since instructions would take longer to finish, correct? I would be interested in knowing where all the voltage changes occur. does anyone know?
[EVO 4G Android Development] netarchy:
That's not accurate at all.

The voltage used for 128 and 245 is the same (only because the evo has problems setting it lower than the value they are set at it would seem).

HELP!!!!

I flashed the kernel "netarchy-toastmod 3.7.3c" using RA-evo 1.7.0.1 and all it does is freeze my phone at the HTCevo white boot screen....... when i format my SD card and wipe the partition it works fine but DC wont allow me to send apps to SD.... any ideas??

I cant use this...

The tearing is just AWFUL! maybe someone can tell me if im not doing something i should but everytime ive tried one of these fps fixes i get terrible tearing issues when an image on the screen moves side to side. the latest being the worst. ive gotta Nova screen using the newest baked snack and i cant understand what would make this usable.:(
[EVO 4G Android Development] ewilson:
Someone please help me understand the benefit in flashing these kernel. What is the benefit in higher fps. What I'm looking for is a better way to send higher mms, better video encoding. Will these kernel allow this. Please help me understand how to use the faster fps.
[EVO 4G Android Development] freeza:
Gotcha. So using 128 or 245 would use the same amount of battery power. Which means there's really no point in using 128?
[EVO 4G Android Development] reallynotnick:
Cool, I have been wanting to see these for awhile, I assume these are the undervolted numbers?

I have seen people able to decrease the voltage to 950mV, idk if that is possible with your kernel but it would be nice.

[EVO 4G Android Development] edtate:
Not everyone's screen is the same. Use evoswitch to find the best refresh rate for your screen. Just mess around; I had the same problem when i was on the 1.47 ota kernel before jumping ship to cm6.
[EVO 4G Android Development] netarchy:
The benefits of uncapped fps are apparent through all general use of the phone.

The UI feels smoother/more fluid, the touchscreen is more responsive, many games tend to run better, etc. It's more of an overall benefit to the user experience of the phone.

The best thing I can suggest is to try the fps fix, and that will probably answer your questions better than anyone ever could.
[EVO 4G Android Development] donnieblasko:
This just happened to mine - had it sitting on my desk all day, and it suddenly rebooted, and came back with no gps, no radio, no service, and acted really sluggish (at the very least it was FPS capped, although it seemed < 30fps in the menus). I rebooted, and reflashed 3.7.3c just in case, and everything seems to be working fine now.

Hopefully this isn't a reoccurring problem.

Does anyone else notice a battery use issue with 3.7.3c I was using 3.6.4 and seemed fine. After flashing 3.7.3c my Cell Standby, Android System, and Phone Idle have all gone up 10% or more than normal.
[EVO 4G Android Development] MSmith1:
I'd have to agree. After a couple of days of testing, 3.6.4 gave me MUCH better battery life when using SetCPU. I'd love to see that type of battery life again. Perhaps undervolting the low end? I know a lot of people are obsessed with speed and benchmarks and I completely understand that but, I am as obsessed, maybe even more so, with battery life. There are a bunch of builds per each revision already but I'd love to see a "battery saver" build. Just a suggestion for us that are obsessed with battery life.

Edit: By the way, impeccable work Netarchy. You are a G and your work is MUCH MUCH appreciated.

Thanks for getting back with me this is my first android phone coming from Wm,and iPhone. Question I'm running DC 3.2.3 with everything working including 4g great speed on 4g. Wifi working now which one of your kernel show I flash on top of this DC rom. Will I lose wifi and Bluetooth and 4g. I've been reading and see a lot of people loosing this. If I restore from clockmod back just In Case things break will it overwrite this kernel. Sorry if I'm really asking question already ask and answer.
[EVO 4G Android Development] onyx00:
Another piece of feedback - 50 fps when flashed initially. Now 40 fps after reboot. Weird. I'll have to mess around with the specific refresh rates when I get a chance. But I need to know how I would go about doing that - do I have to change something in the Kernel or is there an easy to use app to change the values?

Or even better, any thread discussing tweaking these?
[EVO 4G Android Development] MSmith1:
Just caught this bug too. I was averaging 53fps back to locked in at 30...

[EVO 4G Android Development] netarchy:
If you grabbed the epson2 kernel on the dc thread, it is VERY out of date (and only works for people who have an epson panel in their phone), if you're using DC get the DC compatible build from the first page of THIS thread. ;D
[EVO 4G Android Development] ewilson:
OK thanks I will do that. I also have version 0003 is that epson panel
[EVO 4G Android Development] netarchy:
It appears that every person who has posted with an issue of fps going back to <30 at some point is using unrevoked.

Unrevoked is _not_ a full root, and there is a very good chance that if you're not fully and properly rooted you may run into issues.

I personally have no confidence in unrevoked, ESPECIALLY after unrevoked 2 screwed up 4g for a lot of people.

I highly advise fully and properly rooting your phone, complete with nand unlock.

For windows users, you can use SimpleRoot to root your phone.

Linux users can use Bash SimpleRoot.

Running the Fresh 3.7.3 version and wondering if anyone else has noticed any issues with trying to pull up the camcorder from another application, as opposed to opening up the camcorder directly.

I run the camcorder app, eveything works fine. I if try to access camcorder from Vignette, or from the camera app, or from 3D Gallery, or anything else, then phone instantly reboots.

I don't remember this issue happening at all with the 3.7.3 non-overclocked normal version. Why is there a Fresh version? Everything seemed to work just fine with the normal non-fresh version of the kernel.

Do you see the same problem with 3.7.2a by any chance, or is it specific to 3.7.3c?
[EVO 4G Android Development] randymac88:
What is your recommendation for MAC users? The only method I have found is the OTA route which seems a little clunky. I used unrevoked3 and am running Baked Snack and it's been awesome, but no NAND unlock. Thanks in advance.

I rooted using the full toast part 1+2 going the long way (full adb) here. Still have the reverting back to 30fps problem. Got hit with it today for the first time. I was steadily averaging 53fps.

[EVO 4G Android Development] netarchy:
The general pop build is not 100% compatible with all the features of fresh rom, and in some cases people were experiencing issues, so I packaged my kernel with the ramdisk from fresh to make a fresh compatible version.

If you were not one of the people having issues with the normal build on fresh, by all means use it.

[EVO 4G Android Development] netarchy:
New Revision: 3.7.4

Notes for 3.7.4:

- Updated bluetooth code, courtesy of cyanogenmod

(You may have to re-pair your bluetooth devices)

- A new audio boost tweak has been applied

(This should not have the issues of the previous audio boost)

- Fixed an issue that would cause some Nova users to mysteriously

revert to 30fps. (Bad nova! no cookie!)

- Successfully avoided maiming any sabretooth'd tiger-striped cows

during the production of this update.
[EVO 4G Android Development] netarchy:
First you'll need to copy the kernel zip to your sdcard

To flash a kernel you'll need to boot into recovery.

You should always make a nandroid backup whenever making changes to the system (so you can revert back if the proverbial poop hits the fan).

You'll want to flash the zip while in recovery mode, and then reboot to use.
[EVO 4G Android Development] ewilson:
I'm still on the last version 3.7.3 first time flashing this kernel on DC 3.23 do app2sd work with this kernel I check the option on DC config but its not working reboot many times uncheck check nothing is copying over to SD card. I also open root explore all apps still on internal. it was working before I flash kernel. I hate running apps on internal memory.
[EVO 4G Android Development] netarchy:
The custom rom compatible builds combine the ramdisk from the custom rom, with my kernel. For apps2sd to work, it requires some modifications to the ramdisk.

If the DC devs advertise that apps2sd works, then it should work, otherwise your mileage may vary. You should check the DC thread to see if the rom supports it, and if so, how to activate it.
[EVO 4G Android Development] ewilson:
Yes the rom support app2sd I was working before flash to this kernel just didn't know if this kernel breaks it or not. On the rom it allow me to check the box just that no apps get moved over. Is there a better way to move apps over to SD
