Its actually on the top, but the effect is much the same. Even overclocked they don't get very hot, but you could try a tiny heatsink to see if it makes any difference to what speed you can get.normal wrote:I just want to know what temps your getting beforeand after? I read somewhere that the RAM on the RPi is on the bottom of the Soc.. so would it be viable to try to cool the bottom of the board to get smoe extra MHz out of the RAM? Do you even need extra heatsinks/etc on the chip?
I'm not sure why overvolting reduces lifetime, I'm sure Google can help there (it's the same for any semiconductor device).HAZZA24937 wrote:Has anyone bothered with cooling attempts? Will it extend lifetime?
Also what exactly happens when the CPU is over volted, how exactly does it degrade it's lifetime?
You never know for sure until that amount of time has passed.reiuyi wrote:I'd like to know what sort of MTBF (mean time between failures) the BCM2835 is rated at. Is it rated for 10k hours, 50k hours, 100k hours, or perhaps 1M hours? What sort of decrease in lifespan are we looking at when the raspberry pi is over-volted beyond its factory preset?
My pi actually. Mine boots fully to to GUI at 950, but then things start getting wonky. I would overvolt, but definitely waiting until they are more easy to come by.mrbrades wrote:Someone on the RasPi wiki got theirs up to 930MHz!
I have successfully set up config.txt to run using 930MHz arm_freq, 350MHz gpu_freq and 400Mhz sdram_freq.
I can't push it to 950Mhz though, it either hangs on 'waiting for /dev to be fully populated; or kernel panics.
