N64 crashes after 10 min

EndersEnigma

same crash at value
v3d_freq=500

this is quite frustrating.

@endersenigma i told you to remove the overclocks. that's still a VERY aggressive overclock. did you update, also?

quicksilver

@endersenigma have you tried running at stock speed? V3d=500 is still a huge overclock from the standard 300mhz. Your pi might not handle it. What is the exact case and power supply you are using?

The nespi case can cause overheating but that wasn't what happened in my issue. It was due to voltage. Restore your config.txt to default settings and report back

So the plot thickens, if I stop moving just before the freeze at 12 min almost exactly. It freezes for about 15 seconds but the audio keeps playing. If I let it sit till the graphics unfreeze then the game works great. The problem does not occur every 12 min after the first. Just right at the first 12 min.

However, if I am moving when the freeze starts or if I start moving' the audio stops and the freeze is permenant until I pull the power.

I have replicated this 4 times now. The next question is "why". Why right at the 12 min mark does this happen? And why doesn't it repeat at all after that first freeze?

@dankcushions
Without overclocks the games run very choppy and the audio skips a good bit.

Overclocking just the processor seems to fix that problem (1300) but the games are much smoother with the 3D overclock added.

Yes I have updated all packages and tools.

@endersenigma overclock = better performance, lower stability, if you're getting freezes, you need to disable the overclock until you've ruled that out as the cause.

EndersEnigma

@dankcushions
should i just go through the overclocks one by one till i find the culprit?

dankcushions

@endersenigma again, remove them ALL. then see if the crash happens still. if it does, it's a software bug and can be reported.

EndersEnigma

@dankcushions
gotcha. will do that tomorrow and report back.
Thanks for all the help mate.

EndersEnigma

@dankcushions
So I disabled all overclocks, the games still hang and crash (12-14 min of gameplay in). I am not sure what is causing this issue.

@endersenigma please post a copy of your config.txt just to make sure you didn't miss anything. Also what brand/model is your case and power supply? Please also list all devices hooked up to your pi (USB devices, fans, etc.)

@quicksilver
Canakit was my supplier. USB LOGITECH F310 controller is only device connected. Fan is powered by its own plug into the wall.

@endersenigma GPU mem does not need to be higher than 256. No emulator on the pi comes close to using even that much. What case are you using? Do you have a different power supply you can try? I started with the canakit as well and switched. So it may be partially due to that power supply.

EndersEnigma

@quicksilver
the problem is isolated to the N64 emulator. I have no problems with dreamcast or PS1 even when overclocked. I doubt it is the PS but I can see if i have another one to try.

I just installed a new case today.

same issue even with new case.

I will drop down the gpu ram and see if that helps at all.

jonnykesh

@quicksilver he is giving half the RAM to the GPU. You are correct 256MB is more than enough. More is not always better.

quicksilver

@endersenigma did you read the thread that I linked earlier? Like I said I said, I had the same exact issue. Only happened with mupen64-glide. It was a voltage issue for me. I would try a different power supply and see if that solves it (I was also using a canakit when I had the issue)

jonnykesh

@endersenigma who told you to give 512MB RAM to the GPU?

EndersEnigma

@jonnykesh
no change in performance, even the higher demand emulators from 256 to 512. More is better if you are checking to see where the bottleneck is. Since this is a great way to see if its a ram issue by giving more to the gpu, its a great way to troubleshoot if the amount of ram is an issue. My tests show its not in ram or gram. It doesnt seem to be in processor capability either as I have dumbed that down as well in my tests with minimal change till i get into the triple digits. I'm guessing its just a GPU limitation since I have ruled out just about everything else.

quicksilver

@endersenigma who told you that more is better? You are robbing your CPU of memory. Your GPU will never come close to using 512mb of ram. I'm not saying it's the solution to your current issue but you should leave it a 256.

EndersEnigma

@quicksilver
Is there a PS you would recommend since you had this exact same issue before?
