Root Safe cpu speeds?

I am currently running the newest Midnight ROM at max 1.5 GHz and min 648 MHz. My question is this a safe range to stay in? I am only maxing out at 300 MHz over stock so I don't think I am pushing it too much.
 
1.78ghz is the highest my phone (and I think any phone) will go without crashing.

I never really had any problems running it that high either.
 
Its going to be different for everyone's phone. You'll know you went too high when you get random reboots and bootloops

As an example, my evos stock clock speed is 1.5.. I can over clock it all the way to 2.1, but others with the same phone can't get above 1.9 without issues.
 
i usually run around 1.296 ghz max on midnight i dont need much more :D, i have pushed it up to 2 ghz and i started getting random reboots. i try to stay under 1.35 to save battery
 
I have the HTC evo 4g lte not the evo v. So when I said my evo that's not the same evo lol



I probably should have said that to avoid confusion
 
I've gone as high as 1.9 before without issues but didn't run it for too long before I lowered it. I usually keep my 1st core at 1.6 and my 2nd core at 1.5, and keep the 2nd core set to "ondemand" so it's not on all the time... no issues and amazing speed.
 
The phone's cooling system was only designed for 1.2, the chip is designed for 1.5, however not all can even manage 1.5. Between cooling and chip variation, you could do a lot of harm quite fast even going over 1.3 depending on your chip.

Just because you aren't seeing errors that doesn't mean it is safe, and and higher doesn't always equal faster either. Some like to live dangerous and some get lucky, some not so much. Overclocking is never a sure thing, you roll the dice and take your chances.
 
I have been running both cores at. 384 min and 1.512 max on performance Governor. I have no issues. Battery life isn't a concern. I have the best extended battery. It makes my phone thick. But it doesn't bother me...... http://item.mobileweb.ebay.com/viewitem;PdsSession=cee669071390a47a19d66936ffea8ddd?itemId=221125209037&index=0&nav=SEARCH&nid=29472659982

Trust me guys. You won't find a better extended battery. Not the cheapest option. But you get what you pay for. I get two days without being a charge. Even at my overclocked cpu settings

Why on earth would you ever run on performance?

Seriously, this. The only time I ever run on performance is if I'm doing a benchmark for some reason.

Performance makes the CPU always run at the maximum specified speed. Just like powersave makes it run at the lowest.

That extended battery will last a hell of a lot longer if you use ondemand, interactive, or basically ANYTHING else

I run performance because I want performance. :-)

Theres never a good reason to run performance governor. Performance keeps it on the max at all times. There is no min.

Any decent gov will ramp the phone up to max when it needs it and bring it back down when it doesn't.

I feel bad for your CPU and that extended battery :o Your phone isn't built for that

Do you understand what that means? Your CPU is running at FULL SPEED constantly. Even when the screen is off, it's running at 1.5ghz. It's not giving you any extra performance; it's just sucking up more battery life than it needs to.

Use interactive or smartassv2, 192 min and 1.512 max, with a screen off profile, 192 min and 384 max. I guarantee you won't notice a difference in performance
 
If I'm correct If you overvolt you can get higher cpu speeds without crashing or randomly rebooting but why do you need it overclocked to 1.9ghz+. :hmmmm2:
 
I always search for the CPU model number and then search for all of the phones that use that same CPU and the highest I find is always what I use but a step above that. I have yet to do it for this phone.

3: Performance Governor:
This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task, such as syncing email, and returns the CPU to the extremely efficient low-power state. This still requires extensive testing, and a kernel that properly implements a given CPU's C-states (low power states).

5. Performance: It has the same min and max frequency so I guess your phone will heat up and throttle really quick, although if you want to benchmark this would give you the best result.
 
When I looked at my cpu while listening to music and texting and other things the first core maxed out at 1.2Gz "what I have it set at" but the second core went up to 1.596, so for me I'm goin to assume that 1.596 is the max kinda safe speed.

idk if it was a glitch in CPU Master or the kernel or what tho

In that "extremely efficient low power state" the CPU is still maxed out, so I doubt there's much benefit

Either way, its always been suggested to not run performance governor
 
I run xondemand with 384 - 1.566, set on boot as my daily. I also have Juice Defender installed and find my battery life to be adequate. YMMV
