Overclocking discussion
-
@thelostsoul Both can technically shorten the life of your pi. But the raspberry pi engineers designed the pi with limits in place to protect it. That is why by default you cannot over volt past a value of 6 and the pi is designed to throttle itself once it hits a certain temp. Even if the overall lifespan of my pi is shortened a little bit by overclocking I dont really care since it is a $35 computer that I will most likely replace due to obsolescence not equipment failure.

I agree.

At what temperature should I be concerned about crashing?

I don't think it will crash per se but it will throttle significantly at 90C to prevent overheating.

@lachniet if your pi is crashing and you've overclocked, then your current overclock settings are unstable. Your pi will throttle (down clock) itself if it gets too hot to protect itself. Throttling is counterproductive if you are overclocking and should be avoided, so be sure you have a good headsink and possibley a fan as well. A misconception a lot of people have is that heat is the reason overclocks are unstable, this is only partially true. There is a limit to how much overclock your pi will handle even if you keep it nice and cool.

@quicksilver I don't think the pi itself is crashing, since I continue seeing a picture. It may be that lr-mupen64plus is freezing...
Tested on 007, with a pretty high overclock
-
@lachniet yes, usually it's the emulator that will freeze or crash when the overclock is too aggressive. In most cases you should be able to ssh in and reboot safely.

It could still be overclocking. When I was Q3 overclock testing I had an incidence where the game was running but I lost my Putty session and I couldn't reestablish access even though I could see it playing. I had to pull the plug. Any overclock can make your Pi do funny things. Have you tried without overclocking, even if slow, to verify if it still freezes?
-
I have only had it crash once with no overclocking, playing Mario Party 3 on lr-mupen64plus. However, that crash happened after about 30 minutes of playing. The crash on 007 happened within a few minutes.
-
@lachniet instability can show up hours into use if your overclock settings aren't quite stable. I should also note that mupen64-glide is currently having issues on the pi and crashes after 10-20 minutes on stock setups so you may want to avoid testing using that emulator until it gets sorted out.
-
@quicksilver Are the same problems occurring on the libretro port?
-
@lachniet I don't believe so. I haven't used lr-mupen64 that much because it has lower compatibility and performance in general (there are a few games that run better with lr-mupen but not many).
-
I have a question. Is the overclocked Pi 3B without + the "same" if the Pi 3B+ is clocked the same, performance wise?
-
@thelostsoul yes, effectively. you miss out on the wifi, bluetooth and networking improvements, though.

want dank said and the jump from a 1.2 GHz clock to 1.4 GHz
