Re: SD Card Benchmarks

But in many tests on the raspberry pi it says it's slower than the SD card. On my computer with a USB 2.0 port it's much faster. Why would this be? A bug? The raspberry Pi's USB port is driven by the CPU and shares it's bandwidth with the network card and other USB devices. Running a "load tes...

Re: Pi shuts down soon after powering up at random points

Bake it in the oven ;)

Do you have a volt meter? Check the voltage between TP1 and TP2: http://elinux.org/images/d/d1/RPI_Test_Points.JPG (to rule out power supply problems, or crappy microUSB cable)

Re: Raspberry Pi doesn't stay powered up for long.

It seems that the second PI we received was more stable than the first one, despite it having the capacitor loose in the bag. After soldering the cap back it has been running for two days now, playing video in a loop. The first one won't last even 5 minutes before freezing, even with a "cold&q...

Re: Pi shuts down soon after powering up at random points

No change, sadly. It still shuts down. However I do not notice any excessive heat from it when it crashes. But also, I did not notice any mild plastic melting on mine after 2 minutes. So do you suppose my oven wasn't really running at 500F? If the plastic didn't melt, for sure the solder did not re...

Re: Raspberry Pi doesn't stay powered up for long.

DAMN!!! This model took only 2,5 days to crash. USB port had Card reader and PI was under some load.. :twisted: Is this Batch also bad!?? Doing more duration tests... Now with no USB device. The USB ports can't take much load at all. Got a voltmeter? Check TP1-TP2 voltage WHILE the Pi is booting up...

OK.. PowerSupply gives 5.0, polyfuse gets 4.9, and passes 4.8v through with Nokia N8-00 USB cable. Even with Hama Micro.USB-2.0 HighSpeed 1,8m with gold connectors cable did not work good. TP points were 4.7v. So.. Cable takes atleast 0.1v - 0.2v off.. :evil: 4.8v is the absolute bare minimum your ...

109F and more, no fan, 89F with fan... That's not overheating ;) When it gets to 185f then it's overheating. If your Pi is stable when cooled by a fan, you have the same problem as everyone else here. Your Pi was under cooked from the factory. Either send it back for a replacement, or cook it in th...
