Re: raspberry pi making a noise (not from audio)

About the only components that can possibly make noises on the board itself are inductors - the changing magnetic field stresses the ferrite, and if they weren't glued correctly, the bits chatter together. Other than being annoying, they shouldn't be a problem - I don't believe their life will be s...

raspberry pi making a noise (not from audio)

This may sound strange but my Raspberry pi 3 while running on only ethernet and power (or even wifi) makes a strange sound, if it's queit I can hear it clearly without needing to get close! It's making me worry, benchamrking didn't make a big diffrence (it did make a diffrence, just a very small one...

Re: Is this overclock safe for everyday use?

If lets say I somehow magically kept my processor as 30 degrees at all time. could I just raise the voltage without problem? I assume at anything near 1.5v or even 1.8v the processor would somehow break without burning itself right? otherwise you could just raise it to infinity :D does the transist...

Re: Is this overclock safe for everyday use?

Hi kamhagh, I'm not yet an expert but i'm going to give you some clues. Overclocking any kind of processor should not be a problem if : -1) the IC timings meet required specifications (memories access time, and so on...) over your temperature range needs, -2) the chip temperatures meet required spe...

Re: Is this overclock safe for everyday use?

Do you have £30 to test it out ;-) Anything over the official overclock region (which is none with the Pi3 at the moment iirc) is a risk and 'not safe' But then where is the fun, do as you do with standard PCs (Intel/AMD) and take your risks :-D yeah i guess :D I have been burning money by stupid s...

Is this overclock safe for everyday use?

So I was overclocking my RPi 3 for fun. and It actually made a good difference. I'm too much of a chicken to go for more but I'm currently at over_voltage=7 and arm_freq=1355 and gpu_feq=450. I haven't tried messing with anything else yet, I ran glmark2 and sysbench and they're completely stable. my...

It works now but the speed is still 15.5mb/S from 23.3 it used to be. It was lagging too I assume all raspberry pies lag! Why is my SD card still slower? Is it possi...

Don't overclock your Pi. Why are you overclocking? Do you have heatsink and/or fan? yes I have a heatsink. It didn't go over 80. when i started overclocking i did it with a better ehatsink. It nevr got more then 60-70 degrees It was a bit slow and I did it for fun too :( have I damages my pi? Or SD...

Hi. I just bought rasp pi 3! And I have a few problems with it.

When I try to use "wget" with or without -c on any link it gives me segmentation fault!
