I have been overclocking my CPU lately, sitting good right now at 1.2 ghz. I have it undervolted as well to prevent overheating. My question is what temperature do you associate with too hot? 100 F? more?
I dont like letting my phone get over 95 F, but im just curious to know what is considered a safe temperature range.
I cant directly measure my CPU temp, as that feature is not offered on our phone which really sucks, i have to go by the battery.
I have not the slightest clue but I would think you would go by how it feels in your hand and whether or not you can "smell" the cpu burning. I usually dnt clock it above 1.2 unless I'm gaming which is bad but I have it setup by a laptop cooler so it never overheats. Id say anything more than 90 would be pushing it.....

Not true put it like this our phones automatically shut off @ 122*F I go to 115*F when i play GTA 3 @ 1.5Ghz, but i can clock to 104*F just streaming music on WiFi.
So id say personally probably around 110*F+
Yes 105*F is hot but don't run it that high forever though.
But thats the battery, CPU stays fine so id say if your running 100*F+ For more than an hour than it might overheat??? Not completely sure but like i said everyday i play GTA 3 and get up to those temps.

Do you undervolt your cpu or run it on stock cpu voltages? I'm currently running samurai assassination and my phone always crashes if I undervolt it, and usually crashes when I run it at max voltages, but only when I overclock.

I would consider 114 f overheating, that's when I have setcpu underlock to 800 mhz

Used to but because i play GTA 3 now i dont if undervolt that defeats the sole purpose to overclock so i can play without lag, once you undervolt it decreases performance but however gains in battery life.

The term is underclocking.It might help, but CPU temperatures vary with each phone, the best bet would be to just give it a try.

If you haven't already, you might want to also install a widget that monitors vital stats, like temperature. I use one called TEMP+CPU Pro. It monitors CPU usage, clock speed, temperature, and available RAM and only takes up the space of one icon on your desktop.
I've been capped to 800mhz on a kernel that goes up to 1.3ghz for 2 weeks now. No problems.
Well if it makes your face smile, I run at 600mhz.

Every Epic is different. I can run 1400 all day but can't undervolt at all. Some people can't run over 1200. It just depends on your phone. If things are freezing or shutting down on 1300 or 1400, your phone most likely can't handle it

The phone runs great and crazy fast at 1200 or 1300 but i was just wondering if i could get that little bit extra boost to 1400, but i guess if my phone cant handle those speeds im just going to have to be happy with fast. lol

Ill attach some shots of my new settings...I know for a fact I can't go below -100 with the lower speeds or else I instantly loose random data...if ure still optimistic u can try them...question though...does your phone still freeze up with overclocking to 1.4ghz and no undervolting?

Also, (well its probably not recommended) some people have paid for the Extreme key for Voltage Control and OVERvolted a bit to get 1400 stable but I wouldn't recommend it unless Xan says you are good. The option is there though. I have it but haven't had the need to try overvolting

I think overvolting may help people whose phone crashes say at 1.3. If you have it stable without overvolting, I wouldn't even mess with it. 1.3 and 1.4 are already using more voltage than what's considered optimal for our phones

I find that hilarious that they decided to give up at 1.0. I know that's recommended value, but my phone never even shows any signs of instability at 1.3. In fact, it seems like it enjoys it better.

Sounds right. The stock settings are 1000 high and 400 low. Most people can lower the minimum to 200 with no problem. Some can run at 100 with no problem. Same goes for overclocking. Not all phones can handle 1300 and 1400. Then if you undervolt on top of lowering the minimum to say 200 or 100, you may be getting the wakelock or "Sleep of Death" lol

Thanks yall...after research..i thought i undervolted too much...but i been at that setting since i bought set cpu...i think the difference was..i switched kernel to genocide yesterday..aka..the same day i met the sleep of death..im back to the vision kernel now...what are some of yalls settings for set cpu???
I can go 1300 high to 100 low with on demand and no lock. But runs a little to hot for my taste so I usually go to 1000 to 100 I prefer battery life over speed. I am also running Bonsai that has great battery life on top of it.
For reference im running lostkernel latest release exp+ and starburst 1.7.
At stock clock i hit about 3700 quadrant score. At 1.4 I hit about 3900. But when i go to 1.6 it freezes the phone just about every time and i have to do a battery pull. I can get it to go through maybe one out of 30 times, and i score like 4600...
Is this just the physical limitation of the processor, or is here something i can do? Quadrant always does better on a second back to back run. I wanna see if i can hit 4800. Any input appreciated!

Hmm, well to get the scores I get, I set min to 1600, max to 1600 and performance mode, but I wouldn't leave it like that, I just do it for benching. That would destroy your battery. Any other time I leave it at max 1400, min 200 and on demand and my phone doesn't get too hot. I wouldn't put your phone in the freezer when it's hot. Rapid cooling of hot metal/electrical parts can cause serious hardware damage.
Kinda like how you should never spray cold water on an over heated engine block, same principle.

Its not really a problem. I just noticed my battery was lasting way longer when the phone charges while in deep sleep. I use system panel to monitor cpu usage as well as cpu spy. My setup is crispy clean 2.61 rom, I don't shut any syncs off. I just been running it with the normal samurai governor and decided to experiment with diff governors. In a normal day for me my epic would be at 25-30% battery level. With the phone deep sleeping and charging, on a normal day my epic is now at 50-60% battery. If anybody has the time maybe they can try the same setup and let me know if it does the same for them.
