Yes, but if used with over_voltage, it will set your "warranty" bit.
My warranty was gone long ago... Good thing i have two :) haha

Re: Overclocking

Hi guys, enjoying the new turbo mode and trying it out at 1100MHz with OV8... But would like to know if there is any way of maintaining that speed all the time rather than having it as an "ondemand" setting? Is this possible?

How about when you boot? Is there any noticeable speed boost at all? It is pretty difficult to tell I suppose and it can be easy to fool yourself into thinking it is faster :P

Re: Overclocking

I am using the calculate pi method to 2000 decimal places, and get 21-22 seconds each time, whereas with the clock speed to 800, Senab on his website gets around 19 seconds and even lower with RAM at 500 (not by much though time echo "scale=2000;4*a" | bc -l Hm.

Re: List of games for Raspberry Pi

Airstrike is great game i found in the debian squeeze package list. Also only uses about half CPU.

Re: Overclocking

I just hit

arm_freq=1100
sdram_freq=600
core_freq=300
over_voltage=6

Core doesn't like going up much on mine... But just ran an hours worth of video playback using xbmc and it worked really well, more responsive than usual. Although it does get a tad hotter, its no problem.

Re: Raspberry Pi Cooling system? Successful!

I just want to emphasize that the 5V pin which, although it is on the GPIO header, has nothing to do whatsoever with how the GPIO pins work. You can't program it, you can't turn if off other then unplugging the USB power lead. It is the same as connecting the FAN to e.g. a battery. I am saying this...

Apologies to Gordon. And thankyou for all the suggestions. Have already ordered the M/F connectors, will see what i can do when they arrive. :)

Re: Raspberry Pi Cooling system? Successful!

I think you're bonkers and I think the Broadcom people are right, don't bother with a fan &| heatsinks... Oh come on. I did this for the sole purpose of learning how the GPIO pins work, picking up some general knowledge, and because i wanted to play an (admittedly tiny) role in finding out the diff...

Thank you all for your responses. Today the fan arrived, along with a 12mm heatsink I ordered and some thermal tape. Placed the heatsink on easy with the tape, and wired up the + wire of the fan, to the 5V GPIO pin, and the - wire to the ground pin. Plugged in the pi and bingo, fan starts up and wor...

Re: Raspberry Pi Cooling system? :D

In short, try to check out that fan's spin-up voltage. If it's higher than 3.3V, it will probably fail to work on your build. Found this site: http://www.digikey.com/product-detail/en/GM0502PEV1-8.N.GN/259-1322-ND/1021172 Says voltage required is 3-6V DC Sounds good! I ordered the fan and parts nee...

Re: Raspberry Pi Cooling system? :D

However, this is a really pointless thing to do. You already seem to understand that the RPi doesn't need any cooling. But you also lose the major advantage of using a SoC, the fact that it is a silent computer. Mounting a fan on acrylic may cause a lot of noise. True, i definitely see your point, ...

Re: Raspberry Pi Cooling system? :D

Current limit and current drawn are two different things If the gpio is limited to 50mA then the fan will simply run slow and constantly hit the limiter how ever if the gpio doesn't have a limiter then the fan will over draw current and may cause damage to the PCB as the tracks feeding the gpio are...

You'd think so, but it's worth checking out the spec of the GPIO before you hook it up. :D Don't want to see the magic white smoke come out. :mrgreen: Haha fair enough...

You see i was sure it did have 5V pins but the more i looked into it the less i was sure. Yeah i thought that would be the way to do it, just wanted clarification, so thankyou!!!
